Certificate of Adjudication 14-5437A authorizes the diversion and use of up to 102,000 acre-feet of water per annum from the Colorado River for industrial purposes.
| |
| The purpose is to identify and establish principles, practices and standards to effectively conserve and efficiently use available water supplies and provide historical and projected average industrial water demand.Facility Location The South Texas Project Electric Generating Station is owned by NRG Energy, Inc., Austin Energy and CPS Energy as tenants in common. Until late 1997, Houston Lighting& Power Company was the designated Project Manager for the owners. In November of 1997, the STP Nuclear Operating Company (STPNOC) assumed operational control of the South Texas Project. The South Texas Project is located approximately 15 miles southwest of Bay City, Matagorda County, Texas, along the west bank of the Colorado River. The station encompasses a total of 12,220 acres. The South Texas Project has two, 1,350-megawatt Westinghouse pressurized water reactors and both units together produce enough electricity to serve over two million homes and businesses throughout Texas.With nearly 1300 employees, the STP Nuclear Operating Company is the largest employer and source of revenue for Matagorda County.Water Use Data Water Accounting Data Water is an essential component in electricity production.
| |
| The South Texas Project uses both groundwater and surface water for station purposes.
| |
| Most of the water used by the South Texas Project is needed to condense steam and provide cooling for plant generating systems. A diagram of the plant water systems is shown below.71t' ., 1 South Texas Project Water Conservation Plan Groundwater provides onsite drinking water for station personnel, replenishes the Essential Cooling Pond, and is used for other industrial purposes including makeup to the reactor and steam systems. Groundwater is supplied by five onsite wells with a combined capacity of approximately 1950 gallons per minute. Surface water is diverted intermittently, based on reservoir level and water quality, from the adjacent Colorado River to the station's Main Cooling Reservoir.
| |
| The Main Cooling Reservoir is a 7000-acre, above grade, off-channel reservoir capable of impounding 202,600 acre-feet of water at its maximum level. In addition, the Essential Cooling Pond, a 47-acre, below grade, off-channel reservoir that supplies water to cool important plant components is capable of impounding 388 acre-feet of water. Various water rights permits, contractual agreements and compliance documents authorize the South Texas Project to maintain these reservoirs, impound water diverted from the Colorado River, and to circulate, divert and use water from these reservoirs for industrial purposes to operate the plant. Colorado River water is diverted using two 240 cubic feet per second and two 60 cubic feet per second pumps to the Main Cooling Reservoir through a 108-inch pipeline where the water is used for cooling. The table below lists surface water and ground water usage for the last 5 years.Table 1 South Texas Project Electric Generating Station 5 -Year Water Usage 2004 21005 2006 2067 2008 5 year Previous Permitted Average Plan Amount A Average Surface Water 62374 5694 50012 58740 10303 37425 46549 102,000*(Acre-feet)

| I I I I I* Certificate of Adjudication 14-5437A and Contractual Permit No. CP-327**Coastal Plains Groundwater Conservation District Permit No. OP-04122805 After being used in various processes at the generating station, the water is routed to wastewater treatment facilities located at the generating station where it is treated and discharged in accordance with a Texas Commission on Environmental Quality wastewater discharge permit into the Main Cooling Reservoir for reuse. The main consumptive use of water is evaporation and designed leakage of water from the Main Cooling Reservoir and Essential Cooling Pond. The annual consumptive use of water through evaporation is limited to 80,125 acre-feet per year by the Colorado River diversion permit. In 2008, the amount of water consumed from the Main Cooling Reservoir was 38,186 acre-feet or 0.58 gallons/kWh.
| |
| The typical consumption for a 2 South Texas Project Water Conservation Plan nuclear plant with pond cooling is 0.4- 0.72 gallons/kWh'.
| |
| This is also consistent with the report "Water Demand Projections for Power Generation in Texas" prepared for the Texas Water Development Board by the Bureau of Economic Geology, 2008. STPNOC provided comments and a simplified water balance for inclusion in the 2008 report.Projected Surface Water Demands Surface water demand is dependent on climatic conditions as well as the capacity factors of the generating units. Although no routine discharge has occurred from the Main Cooling Reservoir, current projections on reservoir water quality and additional demands up-river may necessitate use of our permitted reservoir blowdown system to maintain water quality.In September of 2007, NRG Energy, Inc., CPS Energy and STP Nuclear Operating Company filed a Combined Construction and Operating License Application (COLA)with the United States Nuclear Regulatory Commission to build and operate two new additional units, Units 3 and 4 at the South Texas Project site. In September of 2008, STP Nuclear Operating Company filed a revision to the COLA application to reflect a change in the engineering, procurement and construction contractor for Units 3 and 4.The proposed units will be built adjacent to the currently operating Units I and 2 on existing station property.
| |
| The station's 12,220-acre site and 7,000-acre cooling reservoir were originally designed for four units. The proposed new units will produce 2700 megawatts, provide enough power for an additional two million homes and businesses, create jobs and provide other substantial local economic benefits.
| |
| Surface water use is expected to increase to 102,000 acre-feet per year by 2020 verses 2030 due to the new units. The 2011 revision to the Lower Colorado Regional Water Plan will reflect use of 102,000 acre-feet of surface water per year by 2020 for steam-electric water demand in Matagorda County. The consumptive use limit remains the same as specified in the diversion permit.The 2011 revision to the Lower Colorado Regional Water Plan will also reflect the 2006 amended contract between STP Nuclear Operating Co. and the Lower Colorado River Authority.
| |
| Under the contract Water Delivery Plan, the available surface water supply of backup water from the Highland Lakes is limited to 20,000 acre-feet/year (as a 5-year rolling average) with two generating units in operation (as is the case through 2015) and to 40,000 acre-feet/year (as a 5-year rolling average) with any additional generating units in operation (beginning in the year 2016).In 1996, the South Texas Project and Houston Industries Incorporated initiated a joint effort with Ducks Unlimited and other agencies to establish a 110- acre wetland habitat for migratory waterfowl at the station. Surface water (220 acre-feet in 2008) is diverted from an adjacent Lower Colorado River Authority rice canal to flood the area from November to March of each year. The agreement with Ducks Unlimited expires in 2011 but current plans are to continue flooding the area as in previous years.1 Power Generation Water Use in Texas for the Years 2000 through 2060, Final Report.Prepared for the Texas Water Development Board by Representatives of Investor-Owned Utility Companies of Texas, January 2003 3 South Texas Project Water Conservation Plan Projected Groundwater Demands Due to the addition of Units 3 and 4, groundwater demand is projected to double, up to the permitted limit, by 2020. STPNOC is also evaluating installing additional wells to meet the increased demand of a cooling tower that is part of the new units design. Any new wells will be installed and permitted through the Coastal Plains Groundwater Conservation District.Existing Water Conservation Measures In past years, water conservation has not been the major impetus for operational changes or installation of new equipment at the generating station. The surface water contract has a guaranteed purchase price whether the water is pumped or not. The modification process associated with making changes to a nuclear generating facility is very costly so potential water savings do not necessarily equate to economic savings. However, the station traditionally has implemented water conservation measures to incorporate best management practices necessary to preserve this valuable resource.
| |
| The following list identifies measures that are currently in place at the generating station. Please note that these measures are subject to change from time to time.1. Main Cooling Reservoir Blowdown:
| |
| No routine discharge has been required from the Main Cooling Reservoir.
| |
| Main Cooling Reservoir water quality is maintained by selective diversion from the Colorado River during excess flow conditions.
| |
| : 2. Flush Valves: Automatic and manual flush valves have been installed to help maintain a minimum chlorine residual in the far reaches of the potable water systems while minimizing water use.3. Cooling Towers: Cooling towers are used for the Nuclear Support Center. Cooling tower blowdown is routed to sanitary waste for ultimate discharge to the Main Cooling Reservoir for reuse.4. Landscape Irrigation:
| |
| Most of the area around the generating station is not watered.Limited watering is conducted at the east entrance and certain office buildings.
| |
| : 5. Closed Piping System: By using piping systems to transfer all water within the generating station, transportation losses are virtually eliminated.
| |
| : 6. Meters: Water meters on each well measure the amount of groundwater used at the generating station.7. Main Cooling Reservoir:
| |
| The Main Cooling Reservoir is capable of containing 202,600 acre-feet of water that is stored and re-used. Internal outfalls discharge into the Main Cooling Reservoir, which is then re-used as cooling water. The Main Cooling Reservoir Maximum Operating Level has been increased from 45'to 47'MSL to take advantage of reservoir makeup opportunities when river flows are high.4 South Texas Project Water Conservation Plan 8. Reuse of HVAC Condensate:
| |
| Modifications were implemented to re-route the Mechanical Auxiliary Buildings and Fuel Handling Buildings HVAC condensate from sanitary waste to the Essential Cooling Pond.9. Reuse of Steam Generator Blowdown:
| |
| Blowdown from the steam generators is reused in the secondary system.10. Chemical Addition:
| |
| Addition of ethanolamine in the secondary system reduces the number of ion exchange demineralizer regenerations required which minimizes water use.11. Reverse Osmosis for Demineralized Water Production:
| |
| Use of reverse osmosis for production of demineralized water increases the capacity of ion exchange demineralizers.
| |
| This reduces the number of demineralizer regenerations and associated water use.12. Reverse Osmosis for Silica Removal: The use of a reverse osmosis unit to remove silica from the refueling water storage tank requires less makeup water than a feed and bleed operation.
| |
| : 13. Re-use of Stormwater:
| |
| The majority of the stormwater collected in the berms that provide secondary containment for oil bearing equipment is treated and discharged to the Main Cooling Reservoir for re-use.14. Essential Cooling Pond: Conjunctive use of groundwater for maintaining water level and quality reduces the need for blowdown from the pond to the Main Cooling Reservoir.
| |
| Blowdown from the pond is returned to the Main Cooling Reservoir for re-use.15. Rainwater Harvesting:
| |
| Rainwater is collected in the 7000 acre Main Cooling Reservoir and 47 acre Essential Cooling Pond for reuse. The annual local rainfall is 42 inches. This equates to an average collection of 24,665 acre-feet per year.16. Waterless Urinals: Waterless urinals conserve water and require less maintenance.
| |
| One has been installed in the Nuclear Support Center, one in the Unit 1 One Stop Shop, and two at the Metrology Laboratory.
| |
| Conservation Measures Implemented Since the Last Revision 17. Main Plant Potable Water Meter: A flow totalizer was installed in June 2005 on the Main Plant Potable Water System to measure the amount of potable water supplied to the Units 1 and 2.Protected Area and the west side of the site.18. Replacement of the Unit 1 and 2 Low Pressure Turbines:
| |
| Replacement of the low pressure turbines in Unit 1 in October 2006 and Unit 2 in April 2007 gained approximately 70 megawatts for each unit. Due to the improved efficiency of the new turbines with no increase in reactor power, the heat load on the Main Cooling 5 South Texas Project Water Conservation Plan Reservoir was reduced. This modification is an example of increased generation using the existing surface water resource.19. Amendment to Certificate of Adjudication 14-5437A:
| |
| This amendment was granted by the Texas Commission on Environmental Quality on March 17, 2009 and allows diversion of surface water above the Bay City Dam. Colorado River water above the Bay City Dam is not within the tidal influence of the Gulf of Mexico so water quality in the Main Cooling Reservoir can be preserved during low river flow conditions.
| |
| : 20. Flow Meter Instrumentation:
| |
| Instrumentation was installed in the reservoir makeup pipeline in March 2008 to verify surface water diversion consistent with the surface water supply contract.21. Fire Protection System: Extensive work has been done over the last 3 years to fire hydrants and valves to repair internal and external leakage.22. Kaydon Units: Use of the Kaydon units was discontinued for turbine electro hydraulic control fluid filtration in 2008.Water Management during Drought Conditions The water right for the South Texas Project, granted with a 1974 priority date, includes a special provision to limit diversion from the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflows during low river flow conditions.
| |
| As the last diversion point on the Colorado River just upstream from Matagorda Bay, the diversion facility is within the tidal influence of the Gulf of Mexico. As mentioned previously, reservoir quality is maintained by selective pumping during high river flow conditions
| |
| (>1200 cfs). The contract Water Delivery Plan shown in the table below has been incorporated into standard operating procedures that require actions at decreasing Main Cooling Reservoir levels, where reservoir water quality is sacrificed to maintain level during drought conditions.
| |
| Main Cooling Reservoir (MCR) Level Actions Normal operating level between 40 and Pumping under River Permit when river conductivity is 49 feet Mean Sea Level (MSL) <2100 pis/cm OR River TDS level is < 1260 mg/L.(Notes 1, 2 & 6)Pumping under River Permit when river conductivity is< MCR conductivity. (Notes 1, 2, & 6)MCR level between 36 and 40 feet MSL IF water deliveries are being made to meet bay and estuary requirements, THEN daily communications with LCRA are required, as necessary. (Note 3)(Chemistry/Environmental action)MCR Level at 37 feet MSL STPNOC requests LCRA to prepare for delivery of backup water when MCR level drops to 35 feet MSL.6 South Texas Project Water Conservation Plan Pumping under River Permit when river conductivity is<10,000 pts/cm OR River TDS level <6000 mg/L. (Note MCR level between 32 and 36 feet MSL 1) Daily communications, as necessary, with the LCRA if deliveries are being made to meet bay and estuary requirements. (Note 3) (Chemistry/Environmental action)LCRA begins staged deliveries of firm water to ensure that MCR level does not drop below 27 feet MSL. (Notes 4 & 5)MCR level below 35 feet MSL Delivery of firm water subject only to the LCRA bay and estuary restrictions; NOT River Permit stream flow restrictions.
| |
| Note 1: Current stream flow restrictions of 55% of river flow over 300 cubic feet per second (cfs) would apply unless and until such time as permit is amended to establish other limitations for diversion.
| |
| Note 2: Reservoir blowdown will commence as necessary to maintain MCR water at an average of 3000 ps/cm.Note 3: To maintain MCR level as high as possible, the LCRA will communicate to STPNOC if the LCRA determines that any additional supply may be available in the river for diversion by STPNOC over and above the amounts to be supplied by the LCRA to meet its other demands. STPNOC may divert such water at its discretion, subject only to the LCRA bay and estuary restrictions.
| |
| Any diversions of water by STPNOC that is made available under this condition and that would not be permitted under the River Permit stream flow restrictions would count towards the maximum quantities to be made available as provided in Note 4.Note 4: The LCRA will provide firm water for diversion by STPNOC up to installed pumping capacity, with a minimum rate to be specified by STPNOC to assist in maintaining the reservoir level at or above 27 feet MSL. Under no circumstances will the LCRA make available firm supply under this condition totaling more than 20,000 acre feet per year (af/y) (rolling five-year average) for 2-unit operation OR 40,000 af/y (rolling five-year average) for any additional generation capacity.Note 5: At 30 feet MSL, STPNOC and the LCRA will pursue an emergency suspension of permit pumping restrictions. (Chemistry/Environmental action)Note 6: WHEN river conductivity exceeds addendum specifications, THEN diversion only allowed with approval from Chemistry or Environmental Management.
| |
| Water Conservation Goals and Initiatives Although no routine discharge has occurred to date from the Main Cooling Reservoir, current projections on reservoir water quality and additional demands up-river may necessitate use of our permitted reservoir blowdown system to maintain water quality.The 2006 revision to the Lower Colorado Regional Water Plan reflects use of as much as 80,000 acre-feet per year by 2010 and the 2011 revision to the plan will reflect full utilization of the water right by 2020 to support four unit operations, making a run-of-river surface water reduction goal impractical other than to stay below the permitted amount under the water right for surface water and below the water supply contract for stored water.STP Nuclear Operating Company is committed to operating the South Texas Project in a safe, reliable, economical and environmentally sound manner. Water conservation is part of this commitment.
| |
| In reviewing water conservation measures, the ability to conserve water is most often a function of the design of the installed equipment and therefore there 7 South Texas Project Water Conservation Plan is limited potential to conserve additional water after a system is installed.
| |
| Including water conservation, and its associated economic benefit, as one of the considerations used when comparing new project alternatives may ultimately have the greatest impact on water use at the generating station in the future. Additional water conservation measures will be evaluated and implemented, when practical.
| |
| General water conservation initiatives are listed below.1. Consider water conservation and its economic benefit when evaluating modification and project alternatives for systems, processes, or equipment that use water.2. Monitor the quantity and quality of incoming water from both groundwater and surface water sources.3. Ensure water leaks are prioritized and repaired in a timely manner.4. Provide water conservation awareness to station personnel.
| |
| Specific conservation initiatives are listed below.1. Continue with the plan to raise the Main Cooling Reservoir maximum operating level from 47' to 49' MSL.2. Calibrate the instrumentation in the reservoir makeup pipeline to verify surface water diversion consistent with the surface water supply contract.3. Monitor the amount of demineralized water produced per day.4. Measure the amount of water being returned to the Main Cooling Reservoir via the well water header pressure relief valve to determine if a cost-effective alternative exists.5. Add a totalizer to the Nuclear Support Center cooling tower blowdown supply line to optimize the amount of water supplied to the cooling tower.Water Conservation Plan Elements Recommendations, evaluations and revisions to this plan will be tracked using the South Texas Project Corrective Action Program.Water Use Measurement Surface water is diverted from the Colorado River and stored in the Main Cooling Reservoir located onsite. River water is diverted using two 240 cubic feet per second and two 60 cubic feet per second pumps to the Main Cooling Reservoir through a 108-inch pipeline where the water is used for cooling. The quantity of surface water diverted is conservatively estimated using pump capacity and run time.Groundwater supplied from five onsite wells located at the generating station is used for potable water and other industrial uses. Groundwater is measured at each well using an inline flow totalizer.
| |
| Reports on water usage are submitted annually to the Texas Commission on Environmental Quality and the Texas Water Development Board.Reports of groundwater usage are also submitted to the Coastal Plains Groundwater Conservation District annually.8 South Texas Project Water Conservation Plan Leak Detection Inspection of piping for leaks is viewed as a normal part of all employees' duties.Operations personnel perform routine inspections each day; they note any evidence of leaks and submit work requests for repairs. Employees also report plumbing leaks promptly.
| |
| A procedure has been developed for leak identification and prioritization for timely repair (OPGP03-ZA-0133, Fluid Leak Management Program).
| |
| The program also provides guidance for a proactive approach to preventing leaks.Best Management Practices Best Management Practices (BMP)2 that were considered during the development of this plan are as follows: " Industrial Water Audit* Industrial Submetering Industrial Water Audit The Industrial Water Audit BMP was used to identify the relationship between water coming into the facility and the various uses of water within. Based on the 2008 annual water use report, the largest use of surface water (100%) was evaporation and designed leakage from the Main Cooling Reservoir.
| |
| The two largest uses of groundwater (80%) at the facility are associated with the production of demineralized water and makeup to the 47-acre Essential Cooling Pond.Industrial Submetering The Industrial Submetering BMP was used to consider calibrating the meter in the reservoir makeup pipeline to verify surface water diversion.
| |
| This meter has been installed but has not been calibrated at the higher river flows due to the prolonged drought that started in 2008. This BMP was also used to consider addition of meters or other flow totalizers for potable water supply as well as the Nuclear Support Center cooling tower water supply. Additional evaluation of adding a flow totalizer or other measure device in the makeup line to the Essential Cooling Pond was not feasible due to its underground location and safety function.
| |
| Adding a totalizer in the secondary makeup line also proved to not be feasible.
| |
| A strap on flow meter is used periodically to estimate the supply to the secondary system.2 Water Conservation Best Management Practices Guide, Texas Water Development Board Report No. 362, November 2004.9 South Texas Project Water Conservation Plan Other Water Planning and Conservation Involvement The South Texas Project was chosen to represent the electric generating utility interest for the water-planning region that encompasses the Colorado River Basin. The South Texas Project actively participates in the Lower Colorado Regional Water Planning Group to identify strategies to meet future water supply demand projections for the region and update the regional plan accordingly.
| |
| The South Texas Project was also actively involved in providing review and comment on the Coastal Plains Groundwater Conservation district rules prior to their adoption and subsequent revision.Regional Water Planning and Coordination This plan is effective May 1, 2009 and the next revision must be submitted not later than May 1, 2014, and every five years after that date to coincide with the Lower Colorado regional water planning process.10 WR-8.

(Notes 4 & 5) Delivery of MCR level below 35 feet MSL firm water subject only to the LCRA bay and estuary restrictions; NOT River Permit stream flow restrictions.
| |
| Note 1: Current stream flow restrictions of 55% of river flow over 300 cubic feet per second (cfs) would apply unless and until such time as permit is amended to establish other limitations for diversion.
| |
| Note 2: Note 3: Reservoir blowdown will commence as necessary to maintain MCR water at an average of 3000 Jts/cm.To maintain MCR level as high as possible, the LCRA will communicate to STPNOC if the LCRA determines that any additional supply may be available in the river for diversion by STPNOC over and above the amounts to be supplied by the LCRA to meet its other demands. STPNOC may divert such water at its discretion, subject only to the LCRA bay and estuary restrictions.
| |
| Any diversions of water by STPNOC that is made available under this condition and that would not be permitted under the River Permit stream flow restrictions would count towards the maximum quantities to be made available as provided in Note 4.Note 4: The LCRA will provide firm water for diversion by STPNOC up to installed pumping capacity, with a minimum rate to be specified by STPNOC to assist in maintaining the reservoir level at or above 27 feet MSL. Under no circumstances will the LCRA make available firm supply under this condition totaling more than 20,000 acre feet per year (acre-ft/yr) (rolling five-year average) for 2-unit operation OR 40,000 acre-ft/yr (rolling five-year average) for any additional generation capacity.Note 5: At 30 feet MSL, STPNOC and the LCRA will pursue an emergency suspension of permit pumping restrictions. (Chemistry/Environmental action)Note 6: WHEN river conductivity exceeds addendum specifications, THEN diversion only allowed with approval from Chemistry or Environmental Management.

| ==SUMMARY==
| |
| STP Nuclear Operating Company has contracted MACTEC Engineering and Consulting Inc, (MACTEC) to develop a Conceptual Site Model (CSM) for Units I and 2 at the South Texas Project Electric Generating Station (STPEGS) located in Wadsworth, Texas (Figure 1-1). The purpose of the CSM is to document the geology and hydrogeology as well as to characterize known and potential releases of radionuclides to the environment.
| |
| This information will then be used tp assess impacts of radionuclides on groundwater quality and to design a groundwater monitoring network so that historic and future (potential) releases can be characterized, documented, and remediated, if warranted, before impacted groundwater can migrate off-site.This work has been completed as part of STPEGS' ongoing commitment to environmental protection.
| |
| STPEGS has entered into this Groundwater Protection Initiative as an active member of Electric Power Research Institute (EPRI) and is using this opportunity to voluntarily evaluate current and historic groundwater data to determine if the current monitoring network is appropriate for groundwater characterization.
| |
| This work has been completed by an independent contractor and was performed in compliance with the Groundwater Protection Initiative established by the National Energy Institute (NEI) (NEI 07-07) and the EPRI Groundwater Protection Guidelines for Nuclear Power Plants (EPRL 2007).The NEI 07-07 guideline provides methods and approaches to characterizing, monitoring, and reporting the presence of radioactive isotopes in groundwater at nuclear power stations.
| |
| To better characterize site conditions and develop the CSM, the following tasks were completed: " Assessment of available maps, construction drawings, and aerial photographs;" File review to identify historic releases of radioactive liquids to the environment;
| |
| * Interviews with plant personnel;
| |
| * Evaluation of systems that contain radioactive liquids;" Site walk downs;* Review of Condition Reports to assess historic releases and corrective actions;* Evaluation of drilling methods, well installation and groundwater sampling techniques;" Inspection of existing wells;0 a Evaluation of existing analytical data; and ES-i P.ATrojecrs\5TP

| |
| * Evaluation of data management.
| |
| The following summarizes the current CSM for STPEGS.The geology below Units 1 and 2 consists of stratified interbedded sands and silts. The shallow groundwater is encountered at approximately 20 feet below ground surface (bgs) and groundwater generally flows towards the southeast, towards the Colorado River. Within the shallow aquifer, there is a downward gradient that may carry impacted water released near the surface to deeper zones. Below the shallow aquifer, there is an aquitard approximately 150 feet thick. This is underlain by a deeper aquifer that provides potable water to the plant and surrounding properties (STPNOC, 2008a).Groundwater flow velocity for the shallow aquifer is dependent on the gradient.
| |
| Although the sandy layers in the aquifer generally have higher hydraulic conductivity, the gradient is very low resulting in a very slow groundwater velocity.
| |
| The deeper aquifer is actively pumped for supply water, this increases the hydraulic gradient (and flow direction) and therefore also increases flow velocity.
| |
| However, as noted above, there is a significant sand and clay aquitard in-between the shallow and deep aquifers that prevent hydraulic communication between the two water bearing zones.There are two general ways that radionuclides can enter or be released to the environment:
| |
| I) from the Main Cooling Reservoir (MCR) infiltrating through the overburden soils to the underlying groundwater, and 2) from releases or leaks from plant systems that carry radioactive materials.
| |
| The MCR contributes tritium to the aquifer as part of the plant's design. The MCR has had measurable levels of tritium at concentrations up to 17,000 pCiIL since commercial operation.
| |
| Tritium first began to appear in relief wells about 2 years after detection in the MCR. Extensive monitoring around the MCR completed in 2006 found tritium had migrated to a well about 700 feet west of the MCR as measured from the Dike road. Wells within about 150 feet of the MCR also typically contained detectable tritium. This suggests that the groundwater may migrate about 700 feet per 18 years or about 40 feet per year (ft/year).
| |
| This is consistent with the Updated Final Safety Analysis Report (UFSAR), Section 2.4.13.3.1.2 where the migration rate in the shallow aquifer was conservatively assumed to be about 77 fl/year (Bechtel, 2007).ES-2 p,~TrojeM\sSTIP-EMR GW lmitiativ,\4.0_Delhv=Mets\4.1_Rcpma's\NU~

| Gvwndwater EmIaititve\Text\Fin=l Cuntcepml Site Model.doc Conceptual Site Modelfor Units I and 2, Groundwater Protection Initiative MA CTEC Ernineering and Consulting, Inc., 6234084613 Based on an evaluation of the systems, the most likely source of radioactivity (i.e. tritium) in groundwater within the protected area is from releases associated with the Total Dissolved Solids (TDS) piping and from the secondary system steam condensate.
| |
| The TDS lines have had documented releases that were subsequently repaired, however limited volumes of radioactive water were released to the environment.
| |
| The secondary system steam and condensate also carries radioactive fluids that are drained via steam traps in small quantities to the ground surface. For both of these lines, the concentrations of tritium within the systems may be present at concentrations up to 80,000 picoCuries per liter (pCiL). These leaks and releases are most likely responsible for very localized presence of tritium in groundwater that have been detected at concentrations above background but well below the Environmental Protection Agency (EPA)Maximum Concentration Level (MCL) of 20,000 pCi/L. Please note that all of the systems within the Protected area are located approximately one mile from the property boundary and more than 2.5 miles from the nearest private residence.
| |
| The current groundwater monitoring network at STPEGS further supports this CSM. Slightly elevated levels of tritium (with respect to background) have been detected in groundwater samples collected from wells around the MCR, with only one location exhibiting slightly higher concentrations.
| |
| Geologic boring logs from this location are not available, but this localized occurrence is most likely due to heterogeneities within the formation and the well most likely intersecting a more transmissive zone. Furthermore, the maximum concentration that could be detected in groundwater would be equal to the concentrations in the MCR. As these levels are below the EPA MCLs, there continues to be no significant risk to human heath or the environment from impacted groundwater associated with the MCR.Similarly, although tritium activities in groundwater do not exceed the EPA MCL of 20,000 pCi/L within the protected area, elevated activity has been detected at wells MW-221C and MW-221E, near a historic release from the Unit 2 TDS pipeline.
| |
| Tritium was detected above background first in the shallow well (MW-221C, screened at approximately 40 feet bgs), and later at the deeper zone (MW-22 1 E screened at approximately 80 feet bgs). Due to the slow velocity of groundwater in this area, it is not expected that detectable concentrations of tritium will migrate past the protected area boundary or past the property boundary as the concentrations will naturally disperse within the aquifer and the tritium will decay. There is no significant risk to human health or the aenvironment from impacted groundwater associated with the TDS pipelines.

| |
| These potential data gaps include: " Areas east of the Unit 1 TDS pipeline (including areas downgradient from historic releases);" Areas downgradient from the condensate release areas; and* The deeper aquifer, below Units I and 2.By plant design, tritium has also been detected above background at wells located on the west side of the MCR. Although these data are expected, this does present a data gap when defining the lateral extent of tritium detected in groundwater.
| |
| With the exception of these specific groundwater monitoring locations, the current well network is adequate for screening level data, However, as noted below, additional care should be taken to prevent further degradation of the wells and to protect the groundwater from potential storm water runoff.The CSM is an iterative process. The following conclusions may be drawn on the data presented in this report: " Geology below the site is generally uniform, consisting of stratified, interbedded silts and sands." Shallow groundwater contours indicated that groundwater generally flows slowly to the southeast, towards the Colorado River, with localized impacts from subsurface structures and groundwater mounding from the MCR." Deep groundwater flow is impacted by on-site pumping wells, however regionally groundwater will flow toward the south, southeast, towards Matagorda Bay.a There are approximately 520 piezometers and 35 monitoring wells around the MCR and 25 monitoring wells within the protected area of Units 1 and 2.* Seven monitoring wells are sampled quarterly to evaluate groundwater quality.ES-4 P:-Vroj"tsM\STP

| |
| * The existing groundwater monitoring wells near Units 1 and 2 provide adequate screening level data, but are not protected in accordance with industry (EPA and Texas Commission on Environmental Quality [TCEQJ) standards.
| |
| * With the exception of tritium, no other radionuclides have been detected in groundwater.
| |
| * Low concentrations of tritium have been detected in the shallow aquifer, but at levels well below the EPA MCL of 20,000 pCi/L. These values are also well below the Offsite Dose Calculation Manual (ODCM) limit of 30,000 pCi/L." Slightly elevated concentrations of tritium have been identified in the shallow aquifer west of the MCR and in the shallow aquifer adjacent to the Unit 2 TDS pipeline (as a result of a documented leak).* No radionuclides have been detected in the deeper aquifer or in samples collected from supply wells." Based on a review of available data, it appears unlikely that radionuclides in groundwater (i.e. tritium) migrate past the facility property boundary in excess of regulatory standards.
| |
| Based on a review of available data, there are no significant or unacceptable risks to human health or the environment from site-related radionuclides in groundwater.
| |
| 0 In addition to these conclusions, the CSM has also identified the following data gaps:* The low concentrations of tritium have been detected at MW-258, west of the MCR. To better define the lateral extent of detectable tritium in the shallow aquifer, additional groundwater monitoring should be conducted to understand the -horizontal boundary of* detectable tritium." Several releases have. been documented from the TDS pipelines and associated tanks.Groundwater downgradient from the Unit 2 TDS pipeline has been evaluated, however there are no groundwater monitoring wells downgradient of the Unit I TDS pipeline.* Small quantities of steam condensate are vented to the ground surface via steam traps.There are no groundwater monitoring wells downgradient of the steam traps.* Samples collected from the deeper aquifer have not detected radionuclides.
| |
| However, these samples were collected from the supply wells that are not only screened across large areas, but are also are pumped at high rates. By design, if any radionuclides did migrate to the deeper aquifer, samples collected from the supply wells would be diluted. With the current understanding of the geology and the very low concentrations of radionuclides 0 (tritium) in the shallow aquifer, it is not likely that radionuclides would migrate through the ES-5 PAProjeccASTP

| |
| Should conditions in the shallow aquifer changed significantly, additional investigations within the deep aquifer may be wan-anted.
| |
| Based on the conclusions and data gaps presented above, the following recommendations are proposed to further refine the CSM and to better assess groundwater quality east of Unit 1 and west of the MCR. Additional recommendations are also provided to further support groundwater characterization.
| |
| Groundwater Monitoring Network Recommendations: " Install six additional groundwater monitoring wells to supplement characterization of tritium impacted groundwater.
| |
| These explorations are summarized in Table 10-1 and are shown on Figures 10-1 and 10-2.Monitoring wells MW-801 through MW-803 should be installed to better characterize groundwater quality in the upper parts of the shallow aquifer immediately downgradient of the TDS pipeline and tanks for Unit 1. These wells should be installed with screens intersecting the watertable.
| |
| Monitoring well MW-803 can also be used to monitor groundwater quality down gradient from the condensate steam traps.* Monitoring well MW-804 will be installed within the deep aquifer, but only if radionuclide concentrations in the lower portion of the shallow aquifer exceed the ODCM criteria of 30,000 pCi/L.* Monitoring wells MW-805L/U will be advanced to monitor the upper and lower portions of shallow aquifer groundwater quality west of the MCR. The upper well will be installed to intersect the watertable; the lower well will be installed at approximately 35 to 45 feet bgs, at a similar elevation as the existing well MW-258.* Wells to be installed in the shallow aquifer may be installed using either hollow stem auger or casing drilling techniques.
| |
| * The well to be installed within the deep aquifer (MW-804) will only be installed when data suggest that there may be a plume migrating downward within the shallow aquifer. Because there is always a slight risk of cross contamination between aquifers, this deep well should only be installed when the radionuclide concentration in the lower portion of the shallow aquifer ES.6 PAPWjects\STP

| Inc., 6234084613 exceeds 30,000 pCi/L. This value is 1.5 times the EPA MCL, and is also equal to the NRC reporting criteria as documented in the ODCM.Monitor existing groundwater wells within the protected area annually and monitor new wells semiannually.
| |
| If data indicate that a release has occurred then the frequency should be increased as warranted.
| |
| Groundwater Sampling Recommendations: " Install dedicated tubing within wells that arc sampled regularly to minimize the potential for cross-contamination." Install compression caps to wells completed with flush-mounted protective casing wells to minimize the potential for storm water runoff and other releases that may enter the well and impact the shallow aquifer.* Groundwater sampling techniques are adequate for collecting tritium samples however, should any other radionuclides or chemicals be included in the analytical suite, then additional samples should be collected using Low-Flow/,ow Stress Groundwater Sampling (EPA, 1996)techniques." Collect groundwater samples from newly installed wells at a semiannual frequency for the first year, then if data do not indicate a release, annual sampling will be appropriate.
| |
| Should initial results indicate that releases have occurred or that groundwater is impacted by tritium at concentrations exceeding background values, additional wells may be installed to better delineate the plume and to identify potential sources.Because the current understanding of groundwater indicates that there are no immediate receptors downgradient, or a history of any groundwater samples exceeding the EPA MCLs, the schedule for installing these wells or modifying sampling techniques is not critical and can be prioritized as needed with ongoing groundwater investigations currently underway for Units 3 and 4.ES-7 P:\PwjctsTP

| ==1.0 INTRODUCTION==
| |
| | |
| STP Nuclear Operating Company has contracted MACTEC Engineering and Consulting Inc, (MACTEC) to develop a Conceptual Site Model (CSM) for the Units I and 2 at the South Texas Project Electric Generating Station (STPEGS) located in Wadsworth, Texas (Figure 1-1). The purpose of the CSM is to document the geology and hydrogeology of the Site, identify known and potential releases of radioactive liquids, and assess groundwater quality with respect to radionuclides in the environment.
| |
| The CSM will be used to design a groundwater monitoring network so that historic and future (potential) releases of radionuclides can be characterized, documented, and remediated (if necessary) before impacted groundwater can migrate off-site.
| |
| As tritium is found in all radioactive liquids at nuclear plants, and because it is the most mobile radionuclide in groundwater, tritium data is used as a 'tracer' compound to identify if releases occurred.
| |
| Should elevated concentrations of tritium indicate a significant release, then other radionuclides will also be evaluated.
| |
| The development of this CSM has been completed as part of STPEGS' ongoing commitment to protect public health and the environment.
| |
| STPEGS has entered into this Groundwater Protection Initiative as an active member of Electric Power Research Institute (EPRI) and is using this opportunity to voluntarily evaluate current and historic groundwater data and to determine if the current monitoring network is appropriate for ongoing groundwater characterization.
| |
| This work has been completed by an independent contractor and was performed in compliance with the groundwater protection initiative established by National Energy Institute (NEI) (NEI 07-07), and the EPRI Groundwater Protection Guidelines for Nuclear Power Plants (EPRI, 2007).
| |
| | |
| ==1.1 BACKGROUND==
| |
| | |
| In 2006, as the nuclear industry started focusing on groundwater protection, STPEGS drafted an action plan to better understand situations involving inadvertent radiological releases that had the potential to reach groundwater.
| |
| This action plan was also developed to support communications with the stakeholders such as the local communities, State Regulators, and the Nuclear Regulatory Commission (NRC).1-1 p:wnAVcts\STP

| |
| Inc.. 6234084613 In July, 2006, STPEGS' initiated several actions to support the NEI Groundwater Protection Initiative.
| |
| These include the following: " Developed a site specific plan of action to assure timely detection and effective response to situations involving inadvertent radiological releases to groundwater." Revised procedures to include the notification of Environmental Personnel of spills that involve radioactive material (including secondary water that may contain tritium).* Revised procedures to include formal and informal reporting to appropriate state and local officials, with follow-up to the NRC for significant onsite leaks/spills to groundwater used as a source of drinking water as well as for any groundwater sample results that exceed the Criteria of 30,000 picoCuries per liter (pCi/L), established in the Offsite Dose Calculation Manual (ODCM).* Established guidelines for calculating reportable quantities associated with leaks or spills.* Revised the Reporting Manual to include: 1) informal-notification to appropriate state and local officials;
| |
| : 2) submittal of a 30-day report for any water sample that exceeded ODCM criteria; and 3) reporting of spills and leaks that exceed the Reportable Quantity (if appropriate) for a substance that cannot be remediated to specified limits.* Added an event code to the Corrective Action Program for 10CRF50.75g Decommissioning Items to capture spills and leaks that could impact groundwater.
| |
| * Completed an evaluation of underground pipes, tanks, and the Spent Fuel Pool.* Discussed tritium data with local officials to build trust and to better understand local concerns.* Worked with the Environmental Department at Comanche Peak to ensure consistency for informal reporting to the Texas Department of State Health Services.* Verified that historic groundwater data collected from wells around the Main Cooling Reservoir (MCR) are consistent with expected results.* Completed the Industry Groundwater Protection Initiative Voluntary Data Collection Questionnaires.
| |
| This CSM continues STPEGS' ongoing commitment to protect groundwater and the environment.

The plant buildings encompass approximately 65 acres. The MCR is 7,000 acres and there is a second man made pond, or the Essential Cooling Pond (ECP) that is approximately 47 acres (Figure 1-1). The remaining areas are bottomland, forested pastureland, mixed grass and shrub communities with some areas leased as farm and grazing lands. The elevation of the plant ranges from 15 to 50 feet above Mean Sea Level (MSL) with most of the protected area of the plant constructed at an elevation of 29 feet MSL. The land surface slopes towards the Colorado River, located three miles to the east (STPNOC, 2008b).STPEGS has two 1,350 megawatt Westinghouse pressurized water reactors (PWRs) identified as Unit 1 and Unit 2 that produce up to 3,800 megawatts of thermal energy. Two steam turbine generators then use this energy to provide up to 1,350 megawatts of electrical power each. The protected area (plant buildings) is shown on Figure 2-1. The main surface feature at the Site is the MCR which is formed by a 12.4 mile long earth-filled embankment, constructed above the natural ground surface. The MCR encompasses approximately 7,000 acres, with a normal maximum operating water level at 47 feet above MSL (STPNOC, 2008b).The reservoir contains plant related cooling water with tritium at a concentration of approximately 13,000 pCi/L and is monitored by approximately 520 piezometers and groundwater monitoring locations.
| |
| Per design and per NRC license, low concentrations of tritium are allowable in groundwater as a result of the MCR water infiltrating through the soils, eventually reaching the watertable.
| |
| Groundwater results from monitoring points have never exceeded the Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL) of 20,000 pCi/L, and are not expected to (STPNOC 2008a).2.1 SITE HISTORY In 1971 the Houston Lighting & Power Co., the City of Austin, the City of San Antonio, and the Central Power and Light Co.

Three years later, application for plant construction permits was submitted to the Atomic Energy Commission (AEC) for two reactors located on farmland just north of Matagorda, Texas; construction began in 1976 following NRC approval (STPNOC, 2008b).Unit 1 received a low-power testing license on August 21, 1987, obtained initial criticality on March 8, 1988, and was declared commercially operational on August 25, 1988. Unit 2 received a low-power testing license on December 16, 1987, obtained initial criticality on March 12, 1989, and was declard commercially operational on June 19, 1989. Combined, the two units produce enough electricity to serve approximately two million homes (STPNOC 2008b).STPEGS is currently owned by NRG Energy, Inc, the City of Austin, and CPS Energy as Tenants in Common. STP Nuclear Operating Company (STPNOC) has operational control of STPEGS as well as the responsibility for implementation of associated environmental programs, including complying with NEI 07-07 (STPNOC 2008b).In 2007 STPNOC applied for a license to build and operate two new units (Units 3 and 4) at the Site. As part of the application process, soil borings have been completed and groundwater monitoring wells have been installed to characterize the geology and hydrogeology of the new sites. Data collected to support Units 3 and 4 have also been used to develop this CSM.2-2 PAProjeas\STP

| |
| | |
| ===3.1 REGIONAL===
| |
| LAND USE The areas around STPEGS are predominantly farm and grazing lands for beef cattle. Farm lands in the immediate vicinity include sod and rice farms as well as catfish aquafarming.
| |
| Figure 3-1 shows land use around the plant. Based on a well survey conducted in support of the UFSAR for Units 3 and 4, there are several wells on site to supply potable water and the nearest residence with a private drinking water well is located about 2.5 miles from the plant. Wells identified in this search are shown on Figures 3-2 through 3-4 (Bechtel, 2007).3.2 DEMOGRAPHICS In 2006 Matagorda County had a population of 37,122, ranking 78th in Texas. The County also held a per capita personal income (PCPI) of $24,962. This PCPI ranked 175th in the state and was 71 percent of the state average, $35,166, and 68 percent of the national average, $36,714. The 2006 PCPI reflected an increase of 6.7 percent from 2005. The 2005-2006 state change was 5.8 percent and the national change was 5.6 percent In 1996 the PCPI of Matagorda was $17,619 and ranked 117th in the state. The 1996-2006 average annual growth rate of PCPI was 3.5 percent. The average annual growth rate for the state was 4.7 percent and for the nation was 4.3 percent (www.bea.gov, 2007).The economic base for the area is primarily agricultural.
| |
| The land surrounding STPEGS is used for the following products:
| |
| beef, rice, grain, sorghum, soybeans, and cotton. There is also a commercial fishing industry along the lower Colorado River, East and West Matagorda Bay, The Intracoastal Waterway, and in the Gulf of Mexico. Aquaculture farms are also being developed to harvest catfish for consumer use (STPNOC, 2008a).S 3-1 P.-Projects\ST?

| ===4.0 PHYSICAL===
| |
| SETTIING This section presents the physical setting of the plant, including the regional and local topography, geology, hydrogeology, surface waters, and meteorology.
| |
| Information is summarized from previous investigations as well as the current geophysical investigation that is underway in support of Units 3 and 4.4.1 TOPOGRAPHY The regional topography is relatively flat with a gentle dip towards the southeast and other shallow areas around natural wetlands, streams, and Little Robbins Slough. Closer to STPEGS, the topography has been influenced by construction; the area around Units 1 and 2 has an elevation of approximately 29 feet above MSL with highest elevation being the berm around the MCR, at an elevation of approximately 65 feet MSL. The local topography is shown on Figure 1-1.4.2 GEOLOGY The regional geology of Matagorda County includes the Gulf Coastal Plaines physiographic province within the Coastal Prairies sub-province, which extends as a broad, band parallel to the Texas Gulf Coast. Geology underlying the STPEGS includes deltaic sands and clays. Specifically, there is a thick wedge of southeasterly dipping sedimentary deposits ranging in age from Holocene through Oligocene.
| |
| The regional geology of the area is shown in Figure 4-1 (Bechtel, 2007).The geology of STPEGS has been classified as part of the Beaumont Formation which extends from the ground surface to approximately 14,000 feet below ground surface (bgs). The formation includes sands, silts, and clays deposited in an alluvial and deltaic deposition zone. The soils and groundwater directly below the STPEGS have been referred to as the "Coastal Lowland Aquifer System" and include deposits from: alluvial plains; delta, lagoon and beaches; and the continental shelf Typically each of the stratigraphic units range from several inches to tens of feet thick and are uniformly encountered across the site, with the exception of impacts from construction(Bechtel, 2007).4-1 P-.\Projcts\ST'P

| |
| The filled area extends around both Units I and 2 reactor buildings and the Cooling Water Circulation lines, and extends up to 50 feet bgs. The area of excavation is shown on Figure 4-2. Cross sections depicting the geology are shown on Figure 4-3. Cross sections developed to support the Updated Final Safety Analysis Report (UFSAR) for Units 1 and 2 are shown in Appendix B (STPNOC, 2008b).4.3 HYDROGEOLOGY This hydrogeologic system near STPEGS contains numerous local aquifers in a thick sequence of unconsolidated clays, silts, sands, and gravels. These series extend to thicknesses greater than 1,000 feet and contain groundwater that ranges from fresh, young waters to saline brines (Figure 4-4). The aquifers are pumped locally for municipal, industrial, and irrigation needs. The specific aquifers near the STPEGS include:* Chicot Aquifer;* Evangeline Aquifer;* Burkeville Confining Unit;" Jasper Aquifer," Catahoula Confining Unit; and" Vicksburg-Jackson Confining Unit.As noted above, the Beaumont Formation has been identified below STPEGS. This formation is associated with the Chicot Aquifer and, to a lesser extent, the Colorado River Flood Plain. The aquifer within this formation supports most groundwater wells in the area. The aquifer consists of two zones; shallow and deep, separated by a stiff clay layer that is approximately 150 feet thick (Bechtel, 2007). This sequence is also depicted in Figure 4-4.For the purposes of evaluating radionuclides in groundwater, the shallow geologic environment is the most important to understand in assessing the migration of potentially contaminatcd groundwater and would most likely contain the highest concentration of radionuclides.
| |
| However, as the deeper aquifer is used for potable consumption, this zone was evaluated as part of this effort.4-2 PA.WmjetSTP

| |
| Near the industrialized portion of the site, the localized mounding from the MCR (that has static water level at approximately 40 to 45 feet above MSL)slightly deflects groundwater flow directions, radially away from the MCR. Additional localized impacts are also likely due to the deep foundations of the building within the protected area. The locations of existing wells at STPEGS are shown on Figure 4-5.Groundwater contours in the shallow aquifer below Units I and 2 are presented in Figures 4-6 and 4-7 (however the current monitoring well and piezometer network does not allow for a detailed interpretation to show the specific influences from subsurface structures).
| |
| In the shallow or upper zone, the specific yield for the sandy deposits generally ranges from 10 to 30 percent, with the clay having a much lower storage coefficient, estimated in the confining layers (ranging from I x 10"4 to I x 10-'). The horizontal hydraulic gradient of the shallow water table is very low, as expected with the horizontally bedded soils and regionally flat topography.
| |
| Groundwater velocity in the shallow aquifer is estimated at approximately 40 feet per year (STPNOC, 2008b).Groundwater elevations indicate there is a downward vertical gradient between the upper portions of the shallow aquifer (encountered at approximately 20 feet bgs), and the lower water bearing zones within the same unit (encountered at approximately 80 feet bgs). This is most likely a localized occurrence due to the mounding caused by groundwater recharge from the MCRP, Within the native soils, groundwater velocity in the vertical direction is likely to be much less than the horizontal velocity, however, areas of fill are expected to be more isotropic.
| |
| The deeper aquifer, located 250 to 300 feet bgs, flows on a regional scale toward the southeast.
| |
| However, flow direction is locally influenced by the STPEGS' water supply wells. Groundwater from the deeper aquifer is currently used at STPEGS Units 1 and 2 in plant operations for fire suppression, sanitary, potable drinking water, and demineralized water production, and makeup water to the ECP. Groundwater is pumped from the deep aquifer using five production wells that range in depth from 600 to 700 feet bgs. These wells pump at capacities, or flow rates, of 200 to 500 gallons per minute (gpm) and create a cone of depression in the potentiometric surface that extends across the northern portion of the MCR. Groundwater contours for this zone are shown on Figure 4-8.0 4-3 P:\PtjecnsSTP

| ===4.4 SURFACE===
| |
| WATER There are several surface water and wetland features on the SIP property.
| |
| The most obvious water body is the MCRK The ECP, Kelly Lake, Little Robbins Slough, the toe drainage systems, the MCR Reservoir Makeup Pump Facility (RMPF) and spillway, wetland and estuaries, and the Colorado River also provide aquatic habits for wildlife.
| |
| The delineated wetlands are shown on Figure 4-9. Each feature is discussed briefly below: " Main Cooling Reservoir.
| |
| As noted above, the MCR is a large unlined man made structure designed to circulate cooling water for Units 1 and 2. The static elevation of the reservoir is at approximately 47 feet MSL or 42 feet above the water table. By design, reservoir water infiltrates through the soils column to recharge groundwater below. There are approximately 520 piezometers and 35 groundwater monitoring wells installed around the MCR_ Most of these are used to evaluate the integrity of the reservoir, however six wells are sampled quarterly for radionuclides as part of the plants Radiological Environmental Monitoring Program (REMP).* Essential Cooling Pond. This is also a man-made structure designed to hold sufficient water that if needed would support Units I and 2 in providing additional cooling water. This reservoir is much smaller than the MCR, but is not lined and water is likely to infiltrate into the underlying soils eventually reaching the water table. Note that the tritium levels within the ECP are currently non-detectable because the makeup source is from groundwater from the deep aquifer." Kelly Lake. Kelly Lake is a small shallow lake located to the east of Units I and 2. It is approximately 4 to 6 feet deep and is most likely not recharged by groundwater that is encountered at approximately 15 to 20 feet bgs." Little Robbins Slough. Little Robbins Slough is a natural channel that formerly ran north-south across the present location of the MCRP During construction, the channel was relocated around the west side of the MCR. This slough receives water from the toe/drainage system as well as water from nearby and upstream drainage ditches." Toe/Drainage Systems. The toe system runs around the MCR and captures surface water runoff and seepage from the MCR, ultimately discharging into the Colorado River and Little Robbins Slough. This is a shallow system that may lose some water to groundwater below, but most likely is not in direct hydraulic communication with the underlying groundwater.

Reservoir Makeup Pumping Facility (RMPF). The RMPF is used to divert water from the Colorado River to the Main Cooling Reservoir.
| |
| The RMPF is located north and upstream of the permitted discharge point." MCR Spillway and Blowdown.
| |
| The spillway is used for the emergency release of water from the MCR. The blowdown pipeline is the permitted discharge (TPDES) from the MCR to the Colorado River." Low Lying Wetlands.
| |
| With the construction of Units 1 and 2 and the MCR, there are several large low lying unnamed wetlands that support ecological habitat. These areas are generally located to the east of the MCR and adjacent to the Colorado River.* Colorado River. With the exception of the MCI, the Colorado River is the second most notable surface water in the area. It is the largest river within Texas with a total drainage area of 42,300 square miles, 11,400 square miles of which do not contribute to the river water supply. Groundwater within the shallow aquifer near STPEGS discharges to the Colorado River, East and South of the plant.4.5 METEROLOGY STPEGS is located within a sub-tropical maritime climate region that is also influenced by more continental climate patterns associated with areas to the north. The seasons are characterized by short, mild winters and long, hot and humid summers. Rainfall is common throughout the year with an annual average of approximately 42 inches per year. The prevailing wind direction is from the south-southeast, shifting to north, and northeast for short periods during the winter (STPNOC, 2008a).0 4-5 P:\Pwjects\ST'P

| ===5.0 SYSTEMS===
| |
| As part of the NEI Initiative, an evaluation of all systems that contain radioactive liquids was completed to determine if there are potential areas that warrant investigations and/or future groundwater monitoring.
| |
| These systems include sumps, storage tanks, spent fuel pools, and piping.For assessing the potential impact of radioactivity on groundwater, the systems that are located outside of structures, or within the yard area, are evaluated in this CSM, as these systems have a greater potential to impact groundwater quality, should a release or leak occur. These systems are described below and are shown on Figures 5-1 and 5-2.5.1 COLLECTION SUMPS At many plants, sumps are located outdoors where they may leak or overflow and impact the underlying groundwater.
| |
| At others, they are specifically designed to capture shallow groundwater to prevent water from impacting operations.
| |
| At STPEGS, collection sumps are present throughout the Mechanical Electrical Auxiliary Building (MEAB) to collect liquids for appropriate treatment prior to discharge.
| |
| These coated sumps arc located inside the building as are the associated pipes.Leaks from this type of system, should they occur, would be observed visually and corrected.
| |
| STPNOC personnel also conduct sump run-time trends; should there be a significant change in flow, the systems would be investigated and any leaks repaired.Additionally, because the buildings with deeper foundations were' constructed at elevations below the water table, any releases of tritiated water from internal systems to the sumps would not impact the soils and groundwater outside the structures.
| |
| At the deeper elevations, the groundwater gradient would push groundwater into the building.
| |
| Therefore, releases to the sumps or to floors would not leak out, but would require active pumping to remove the accumulated water. Water could then be sampled and routed to the appropriate treaunent system, if necessary.
| |
| Based on a walk down of sumps within the buildings, as well as facility knowledge, there is little potential for liquids within the sumps or associated piping to release tritium to the environment.
| |
| Please note that there are several sumps used for liquid collection that are located outside the buildings; however, those associated with storage tanks and berms are discussed further below.5-1 PPr:ojects\STP

| | |
| ===3.2 STORAGE===
| |
| TANKS There are several storage tanks at Units I and 2 that store radioactive water, as well as wastewater.
| |
| These include: the Waste Monitor Tanks, Total Dissolved Solids (TDS) Lanks, Liquid Waste Storage Tanks, Refueling Water Storage Tanks, Oily Waste Treatment System Tanks, and Service Water Tanks. Although each storage tank area is bermed, or inside a building, and inspected regularly should a leak occur, tritium could be released to the environment.
| |
| For the purpose of this report, only tanks that store radioactive liquids are addressed below.5.2.1 Yard Area Waste Monitor Tanks Yard Area Waste Monitor Tanks are associated with the Liquid Waste Lines and are constructed of stainless steel with welded seams and welded nozzle connections.
| |
| The waste line system piping is mostly located within the MEAB with a few sections in the Fuel Handling Building (FIB), Reactor Containment Building (RCB) and Turbine Generator Building (TGB). The piping crosses the yard area, within a guard pipe, leading to the Waste Monitoring Tanks (WMT), D, E, and F.These tanks are located on the southern side of the MEAB (See Figure 2-1).The concentration of gamma emitting radionuclides in the water in the outdoor WMT is maintained below 10,000 pCi/L. The tritium concentration could be as high as the Reactor Coolant System (1 to 5 billion pCi/L). Should leaks occur, the system is designed to capture the radioactive liquids within the WMT Sump and the associated Emptying Pump, which would then discharge the liquid back to the WMT.Bly design, the potential for significant releases of radioactive water from these Lanks is low.Regardless, plant operators log the WMT levels daily as part of their rounds and would observe a decline in liquid level if significant leakage were to occur. On a less frequent basis, they are also monitored by the waste system engineer as part of normal system monitoring and freeze protection walk-downs.
| |
| The benna around the tanks are also inspected and cleaned every six months. The maintenance history of the outdoor WMTs has not recorded any leakage from the tanks, and has noted only a few leaks associated with the pump seals. With over 20 years of documentation, there have only been six work orders recorded for external leaks associated with these tanks.5-2

| Inc., 6234084613 5.22 TDS Tanks The TDS tanks are part of the Condensate Polishing System, and each unit includes the following tanks:* 50,000 gallon Cation LTDS* 60,000 gallon Mixed Bed LTDS* 16,900 gallon Cation HTDS* 16,900 gallon Mixed bed HTDS #1* 16,900 gallon Mixed bed HTDS #2 These tanks are located to the east of each of the Turbine Generator Buildings (TGBs) within concrete berms. Tritium concentrations associated with these tanks are typically in the 2,000 to 80,000 pCi/L range and several reported leaks are associated with piping around the tanks. These locations are discussed further in Section 6.0.5.2.3 Liquid Waste Storage Tanks The Liquid Waste Storage Tanks (LWSTs) also referred to as the Waste Holdup Tanks, typically contain concentrations of tritium in the I to 5 billion pCi/L. However, at STPEGS, both LWSTs are located within the MEAB. Should they leak, the releases would be captured by sumps within the MEAB and the water contained.
| |
| Furthermore, should a release go undetected, the hydraulic gradient at the lower elevation levels within the buildings is into the structure, so releases would not be expected to seep out into the surrounding aquifer. At STPEGS, the LWSTs are not a likely source of radioactivity in groundwater.
| |
| 5.24 Refueling Water Storage Tanks Similar to the LWSTs, the Refueling Water Storage Tanks (RWSTs) are located within the MEAB.Should they leak, the releases would be captured by sumps within the MEAB and the water contained.
| |
| Furthermore, should a release go undetected, the hydraulic gradient at the lower elevation levels within the buildings is into the structure, so releases would not be expected to seep out into the surrounding aquifer.5-3

| |
| | |
| ===5.3 SPENT===
| |
| FUEL POOL At many nuclear power plants, spent fuel pools are typically areas that are of particular interest with respect to potential releases of radionuclides to the environment and more specifically to groundwater.
| |
| At STPEGS, the bottom of the spent fuel pools is located on the first floor (elevation 21 feet, 11 inches) in the FHB. The basement floor, or next level down, was constructed at elevation
| |
| -29 feet MSL, so there is approximately 50 feet between the bottom of the pools and the next floor level.The area under the spent fuel pool is periodically entered by plant personal.
| |
| Should a leak occur, not only would it trip alarms, but it could also be visually observed and repaired.
| |
| Additionally, the spent fuel pools have a leak chase channel on the back side of the pool line welds, within the concrete.
| |
| These leak chase channels discharge to telltale drains that are also monitored regularly.
| |
| Furthermore, any weld defect would first leak into the chase channel, then to the telltale drains and would not impact the concrete or be released to the environment.
| |
| As noted with the building sumps, the lower floors of the building arc at elevations below the static water level, and therefore the hydraulic gradient of groundwater would be to enter the building so releases would not be expected to seep out into the surrounding aquifer. Releases of radioactive water would be contained within the building, and pumped/treated as radiologically impacted liquid waste. At STPEGS, the Spent Fuel Pools are not a likely source for introducing radionuclides to groundwater.
| |
| | |
| ===5.4 SYSTEM===
| |
| PIPING Most of the systems that carry radioactive liquids are within the buildings, where the liquids are piped directly into tanks (also located inside). Should leaks occur within these structures, not only would the leaks be visually observed, but they would be captured by floor drains and sumps (discussed above in Subsections 5.1 and 5-2). However, there are several systems that are located within the yard area where a release would not be captured by a floor drain and sump system.Leaks from these piping systems would be the most likely sources of releases of radioactivity to the environment, and if a leak occurred, groundwater quality could be impacted.0 Potential systems within the immediate vicinity of Units I and 2 include the following:

Although the discharge is part of the system design, it still has the potential to introduce tritium to the underlying groundwater prior to surface discharge.
| |
| These systems are the primary locations where tritium could be introduced to the environment.
| |
| As part of a voluntary self assessment, STPEGS also participated in the EPRI Groundwater Protection Initiative:
| |
| Materials Degradation Master Matrix (MDMM) and under this initiative documented all piping details with respect to how likely systems could degrade and leak tritiated water into the environment.
| |
| The results of this effort are provided in Appendix C.A brief description of each of the piping systems that have been identified as potential tritium sources is provided below. The location of each of these systems is shown on Figures 5-1 and 5-2 and additional details are provided in Appendix D.5.4.1 Liquid Waste Discharge Piping The liquid waste system is designed to process radioactive liquids for eventual discharge into the MCR under the NRC License. The system collects radioactive water from various sources within the plant including the equipment drains, floor drains, laundry and regenerated wastes. The liquids are processed through a collection of demineralizers, filters, ALPS and holding tanks (to allow for decay of the various nuclides present in the water) to reduce the concentration of radioactive nuclides in the water below the limits for release into the environment.
| |
| The majority of the liquid waste system piping is located within the MEAB with smaller sections in the FHB, RCB, TGB, and yard area. The portions of the liquid waste system that are in the yard area are associated with WMT D, E and F on the south side of the MEAB. There is one section of 5-5 P:APwjcctsSTP

Otherwise, all of the yard area liquid waste piping is above-ground.
| |
| Most of the liquid waste piping is made of Schedule 40S stainless steel. However, one section of buried piping in the waste line has a 6-inch guard pipe made of class 7 seamless carbon steel. There are also' limited portions of the system made to the other specifications, however, with a few exceptions most of this piping is no longer used (i.e. waste evaporator package, auxiliary steam supply, etc.).Given the low operating pressures/flow-rates in the liquid waste system, and the materials used for the process piping and the process fluid (such as very dilute boric acid and tritiated water), a leak from this system is unlikely.
| |
| However, the locations with the highest potential for leakage are mechanical joints such as flanges and valve packing. Because most of the liquid waste process piping is located indoors, the only area where leaks would present a realistic groundwater contamination issue is on the piping around the WMTs in the yard area and the WMTs themselves.
| |
| Given the materials of construction used for these components and the methods of construction (almost every joint is welded and the one section of buried pipe has a guard pipe surrounding it), leakage or releases to the environment is unlikely.The liquid waste piping that is in the yard area and the WMT is monitored daily during operator rounds. They are also monitored by the liquid waste System Engineer as part of normal system monitoring and freeze protection walk-downs.
| |
| If a release did occur in the yard area, it would quickly be detected.
| |
| Additionally, as noted above, plant operators log the WMT levels daily as part of their rounds and would observe a decline in level if significant leakage were to occur downstream of the WMTs.54.2 Total Dissolved Solids Discharge Piping The TDS pipelines run from the east side of the TGB of each Unit, traveling underground South and then East, entering the North side of the NC Basin. The lines are constructed of filament wound, glass fiber reinforced, thermosetting epoxy resin pipe with threaded, mechanical adhesive or combination type joints.0 5-6 P:XProjects\STP

Prior to 2002 steam generator replacement, this concentration could have been higher due to primary to secondary leakage. Leaks have been documented in this piping and historically identified when water is observed at the ground surface. Since 1994, Unit 1 piping has had 18 underground leaks and one above ground leak. Unit 2 piping has had seven underground leaks.Underground leaks were repaired by excavating the piping and making repairs in accordance with plant procedures.
| |
| Documentation for the releases and repairs are provided in Appendix E. This condition has since been addressed by modifying the timing sequence on the inlet valves to the neutralization basins. Currently, the TDS pipelines are monitored as a routine part of operational rounds and if leaks are identified, they are immediately repaired.5.4.3 Auxiliary Cooling Open Loop Piping and Circulating Water Piping Because they run in parallel from the MCR across STPEGS, the Open Loop Auxiliary Cooling Water Piping and Circulating Water Piping follow similar routes and are discussed as one system.These piping systems are shown together on Figure 5-1.The Open Loop System provides cooling water from the MCR to several systems at the plant, including:
| |
| * Auxiliary Cooling Water and Circulating Water/Closed Loop Heat Exchangers;
| |
| * Non-Essential Heating Ventilation and Air Conditioning (HVAC) Chillers;* Steam Generator Feedwater Pump/Turbine Lube Oil Coolers;* Main Turbine Lube Oil Coolers; and* Generator Hydrogen Coolers.There are two pumps per unit that each operate at approximately 11,900 gpm. The Open Loop piping runs underground through 10- to 30-inch diameter pre-stressed concrete cylinder and pre-tensioned concrete cylinder (bar wrapped) pipe. In addition to piping water from the MCR, this system also receives liquid radiological waste from the Non-Essential HVAC Chillers OC Return Line.

| Inc., 6234084613 The normal failure of this type of pipe is a complete rupture (or fish mouth) and such a failure would be visually observed by plant personnel and immediately repaired.
| |
| Additionally, if a failure occurs, the Control Room will also get an alarm indicating a loss of discharge pressure.The Circulating Water System provides cooling water to .the Main Condensers for removal of beat to the MCR. Three to four pumps are in service (per Unit) with each rated at approximately 225,000 gpm. The piping is made up of 84-inch (located in the Turbine Building), 96-inch and 138-inch (located above and below ground level) pre-stressed concrete cylinder pipe.Similar to the Open Loop piping, the normal failure of this type of pipe is a complete.rupture (fish mouth) and such a failure would be visually observed by plant personnel.
| |
| However, if the failure occurs on the supply side to the condensers, the Control Room will also get an indication of a plant anomaly due to a change in condenser vacuum or a change in pump discharge pressure.A Life Cycle Management Study was conducted for the system's buried pipe in 2002/2003.
| |
| This system has nine failure mechanisms that are categorized into seven categories:
| |
| corrosion; soil* composition (sulfate, chloride and acidic); atmospheric exposure; stray current corrosion; galvanic corrosion cell; differential aeration cell; and hydrogen induced cracking (cathodic overprotection).
| |
| Each category has been assessed and with the exception of the hydrogen induced cracking, all have been addressed and resolved.
| |
| The hydrogen induced cracking assessment is ongoing. Additional details for each failure mechanism are provided in Appendix D.In addition to assessing the potential failure mechanisms, this system is monitored regularly.
| |
| Should there be a leak, it would result in catastrophic failure, not only releasing tritium to the environment, but disrupting plant operations, resulting in a shutdown of power generation.
| |
| As noted above, a failure of this type would not only be visually observed, but sensors within the control room would also alarm, indicating a rupture. In addition to the assessment noted above, the pipe material that is exposed to the atmosphere is sampled every 12 years. Every 2.4 years, or every third cycle, the pipes are also drained to perform material condition inspection to assure that the repairs and deficiencies are corrected and documented.
| |
| Every outage (or 1.5 years) a visual inspection is also completed of the 96-inch above ground pipe and the buried 138-inch pipe.0 5-8 PAPirojcc\STP -EPKJ ow Imtwtivde\4.O DekivnbI~c\4.

| ====5.4.4 Reservoir====
| |
| | |
| Blowdown Piping The Reservoir Blowdown system runs underground adjacent to the spillway and is the permitted discharge from the MCR to the Colorado River. Although there is potential for this line to leak, a release would follow the discharge path via the spillway and discharge to the River. Furthermore, because the approximate concentration of tritium within the reservoir is 13,000 pCi/L, any leak would: 1) not exceed the MCLs of 20,000 pCi/L; and 2) would only migrate further downstream/gradient, discharging to the Colorado River (below allowable limits). This line has been tested in 1997, however this line is not commonly used. There are several monitoring points already along this line and to date, none have had elevated concentrations of tritium.5A.5 Oily Waste Treatment System Piping The Oily Waste Treatment System Piping receives oily waste water, in part, from the TGB sumps in both Units 1 and 2. The lines run underground in between Units 1 and 2, from the Oily Waste Surge Tank to the Treatment System. The piping continues underground and discharges to the MCR. The Oily Waste Treatment System discharge piping is made of ductile iron pipe and cement line.This piping is monitored as a routine part of operational rounds. Plant procedures direct operations personnel to check for process piping leakage in the course of their normal operator rounds. There have been no reported underground pipe leaks and five above ground leaks from pipe or hose breaks, which were repaired as soon as the leaks were identified.
| |
| A slow underground leak from this system may not be detected immediately; however the typical tritium levels within this system range from 1000 to 50,000 pCi/L.5.4.6 Auxiliary Steam System The Auxiliary Steam System pipes were not initially identified as potential systems that could release tritium to the environment.
| |
| However, by design, these lines discharge tritiated water to the ground surface. As this is condensate, the actual tritium concentrations may be detected up to approximately 80,000 pCi/L.5-9 .P:\Prjects\5TP

The steam then travels from the Auxiliary Boiler to the TGB and then to the Liquid Waste stations in above ground from the south side of the TGBs to the Fuel Handing Building The lines are constructed of seamless carbon steel and arc monitored as a routine part of operational rounds.There have been no reported leaks, however as noted above, condensate is released to the ground surface. In addition, due north of the Auxiliary Feed Water Storage Tank and along the south of the TGB on both units, two drain lines continuously leak a mixture of steam and water to the ground surface.5.4.7 Condensate Storage and Transfer Piping The Condensate Storage and Transfers system runs underground between the secondary Makeup Tank and the TGB for each Unit.

| |
| | |
| AND KNOWN RELEASES Known and potential releases are assessed under the NEI initiative to identify the current areas where elevated radionuclides could be present in groundwater; to better understand where the likely source areas are; and to better design the groundwater monitoring network.By design, the MCR releases tritium to groundwater.
| |
| The MCR is a man-made 7,000 acre reservoir.
| |
| With the water elevation of 47 feet MCL, or approximately 42 feet above the static groundwater elevation, the MCR water percolates though the overburden soils causing a local mounding of groundwater, influencing groundwater flow directions in the shallow aquifer. Tritium concentrations within the MCR are approximately 13,000 pCi/L, well below the EPA MCL of 20,000 pCi/L.The infiltration of MCR water to groundwater also introduces low levels of tritium to the shallow aquifer. This impact is part of the plant's design and therefore low concentrations of tritium in groundwater are expected.
| |
| For the purpose of the NEI Initiative, it is important to monitor the extent of impacted water so that the plume boundaries are defined. As long as concentrations are below the acceptable level, no further action will be warranted.
| |
| Similarly, the venting of steam and condensate through steam traps to the air and ground surface does introduce tritium to the environment, however at concentrations that should not significantly impact groundwater quality. Releases from the secondary systems are quantified and reported in accordance with the Offsite Dose Calculation Manual.The intent of the Groundwater Protection Initiative is to understand historic practices and current systems to understand where radioactive liquids could be released to the environment and to ensure that these areas are being monitored, should groundwater become impacted.
| |
| Because of the potential for impacts to the environment, releases should be documented in a Condition Report coded for decommissioning (as required under Code of Federal Regulations 10CFR5075[g]).
| |
| Because the operating levels and allowable discharge of tritium are typically above, the EPA MCL, many lesser historic releases may not have been documented.
| |
| To better assess historic releases, a thorough review of all available files was conducted, followed by interviews with STPEGS 6-1 P:Prhojn\tsSTIP

The documented releases are summarized on Table 6-1 and the locations of theses releases are shown on Figure 6-1.Historic releases occurred across the plant, and upon review, most of the significant releases have been in association with the TDS pipelines-These lines are constructed of fiberglass and have a history of leaking, although all leaks were immediately identified and repaired (Appendix E).These leaks, along with other historically documented releases do not pose a dose-based risk to workers, but they have introduced tritium at concentrations above background levels to the underlying aquifer. This condition has since been addressed by modifying the timing sequence on the inlet valves to the neutralization basins. Releases have also been documented from other systems and storage tanks, however, most of them were of insufficient volume to impact groundwater, or were captured by the storm water collection system and eventually discharge to the plant area drainage ditch (PADD) (see Figure 5-2).6-2 P:AProjectsSTP

| MONITORING NETWORK Groundwater has been monitored regularly at STPEGS since plant construction-Twenty-five groundwater monitoring wells were installed to support construction within the protected area and approximately 520 piezometers and 35 wells were also installed around the MCR to continuously monitor the integrity of the herin Although these wells were not installed to specifically assess tritium in groundwater, they may be used as data points to understand current conditions and to evaluate groundwater quality. Groundwater samples have been collected from various locations site wide as needed, however seven required monitoring well locations are monitored quarterly to specifically monitoring tritium concentrations in groundwater.
| |
| Two of these quarterly monitoring locations are located within the protected area. Groundwater samples are also collected from the water supply wells that draw potable water from the deeper aquifer. The locations of the wells and piezometer stations are shown on Figure 4-5.7.1 GROUNDWATER MONITORING WELLS AND PIEZOMETERS In addition to reviewing groundwater data, the EPRI Guidelines for complying with the NEI Initiative also recommend reviewing well installation and groundwater sampling methodologies.
| |
| The following actions were completed to better assess the appropriateness of existing sampling points:* Conducted a review of the well/piezometer installation procedures;
| |
| * Completed a visual assessment of all wells within the yard area and selected wells around the MCR; and* Observed groundwater sampling techniques.
| |
| The following subsections describe the findings from each assessment.
| |
| 7.1.1 Well and Piezometer Installation Groundwater monitoring wells and piezometers have been installed following industry standards, with an appropriate sandpack around the screened interval, bentonite seal above the screen, and the remaining annulus backfilled with cement grout.

It should be noted that for most, if not all wells, wells screens were installed based on a predetermined depth interval and may not be monitoring the most appropriate interval.However, these data may be used to assess overall conditions of the underlying aquifer and used as a screening tool to better understand the distribution of radionuclides within the water bearing zones.In addition to the existing wells network, concurrent to this evaluation, additional groundwater monitoring wells are also being installed in support of the licensing and planned construction of Units 3 and 4. These locations are also shown as proposed locations on Figure 10-2. However, unlike the historic wells, these wells are being installed with the intent of intersecting specific water bearing zones to provide data for the overall groundwater model. As data is available they will also be incorporated into this CSM.7.1.2 Condition Assessment Most historic wells within the yard area have been completed as flush mounted mad boxes. Some have also been completed with the protective casing extending above ground surface. Based on a walk-down of these wells, several of them were damaged and many did not have compression caps or seals. Should a significant rain fall occur, storm water could enter the well, possibly impacting the geochemistry within the well. A summary of the well conditions is provided in Table 7-1.Existing wells and piezometers installed around the MCR were generally completed with above ground (or stick-up) protective casings. With these, there is less of a potential for storm water to enter the wells. These wells are also sampled and inspected at a higher frequency and appear to be in better condition.
| |
| The new wells currently being installed for Units 3 and 4 have been completed as stickups with locks and have been installed using techniques accepted by EPA, NRC, and Texas Commission of Environmental Quality (TCEQ).7.1.3 Sampling Techniques Groundwater samples are collected on a quarterly basis from nine monitoring wells at STPEGS as well as from the drinking water supply wells.

Groundwater samples are collected by evacuating three to five well volumes to ensure that the samples represent formation water, and not the stagnant water within the well. Typically the same tubing is used for all wells, unless it is worn or visually dirty, in which case it is replaced.Because the water table is located at approximately
| |
| -15 to 20 feet bgs, a peristaltic pump (or IscoTm pump) is used to pull the water to the surface at a maximum rate of approximately

| per minute. During the observation, only one sampling event at well MW-256 was observed, however, based on interviews with the technician, the rate of pumping for this well is typical of others at STPEGS.After sufficient purge time/volume, the appropriate volume was dispensed in the sampling container, and marked with the sampling time and date. Samples were then brought to the on-site laboratory for on-site analysis.7.2 ANATLYICAL DATA Radiological data has been collected from groundwater wells and piezometers since the construction of Units 1 and 2 and of the MCR_ Data are managed by the Chemistry and Health Physics Department and furnished to all stakeholders in the Annual Environmental Operating Report. Available tritium data are provided in Tables 7-2 and 7-3 and are summarized on Figure 7-I. Groundwater samples are also routinely collected for other plant-related radionuclides.
| |
| These data are presented in Table 7-4. Data are also published annually under the Annual Environmental Operating Report that is available to local and federal stakeholders as well as the public.7.2.1 Results No tritium concentrations in groundwater collected from wells and piezometers at STPEGS exceed the EPA MCL of 20,000 pCi/L. No other radionuclides have been detected in groundwater.
| |
| Tritium results show that in general there are low concentrations (i.e. less than 5,000 pCi/L) of tritium in shallow groundwater as a result of: 1) the water in the MCR infiltrating the shallow soils and reaching the water table; 2) from releases from the TDS pipeline and potentially from condensate that is released to the ground surftce.7-3 P:APnjects\STP

The most recent tritium data for wells MW-258 and MW-259 near the western boundary indicated just detectable concentrations, 260 pCi/L and 400 pCi/L respectively.
| |
| Both wells are within feet of the property boundary and are separated from each other by about 20 feet. Tritium detected in these wells indicates that the plume may extend slightly beyond the site boundary.
| |
| These wells were installed with a screened interval at approximately 45 to 50 feet bgs. There is no data from groundwater encountered at the water table or from deeper depths. However, as the MCR is the source of tritium, concentrations will not increase above the MCR concentration, and with radiological decay and dispersion/advection, groundwater concentrations will likely be much lower.Two other monitoring locations around the MCR also reported elevated concentrations of tritium.Increasing trends were noted at MW-235 during 2007 with reported concentrations of tritium at concentrations up to 740 pCifL (with more recent data from 2008 reporting tritium concentrations at 1,000pCi/L).
| |
| However, trend analyses show that MW-251 tritium concentrations have been relatively stable over time, with the highest concentration reported at approximately 5,000 pCi/L for samples collected in 2006. Even though these locations contain elevated tritium, there are additional wells in the area that delineate the plume and no additional investigations are warranted.
| |
| Increasing trends were noted at MW-235 during 2007 with reported concentrations of tritium at levels up to 7,400 pCi/L (more recent data from 2008 show tritium concentrations at 1,000 pCi/L).MW-251 concentrations have been more stable, but are also reported at approximately 5,000 pCifL for samples collected since 2006. Even though these locations contain elevated tritium, there are additional wells in the area that delineate the plume and no additional investigations are warranted.
| |
| Within the protected area, there are some slightly elevated tritium data that are associated with two specific releases from the Unit 2 TDS pipelines.
| |
| The Condition Reports associated with these leaks are provided in Appendix E. Groundwater data collected from monitoring wells 221C and 221E show tritium concentrations ranging from 15,300 pCi/l to 5,140 pCi/L in the upper portion of the shallow aquifer and from 571 pCi/L to 1870 pCi/L in the lower portion of the shallow aquifer.Based on the trends over time, the higher detections were first reported from samples collected from the well screened closer to the water table in the upper portion of the shallow aquifer. With time, these tritium concentrations declined and the concentrations from the well screened in a S deeper zone increased As noted in Section 4.0, there is downward vertical gradient in areas 7-4

It could also be hypothesized that the groundwater sampling techniques of purging three to five well volumes may have pulled the shallow, impacted water, already with a downward gradient, further downward.However, as the concentrations are now declining it does support the theory that the elevated tritium was due to a specific release and with the source terminated, the groundwater concentrations are decreasing both via radioactive decay and more likely via dispersion within the shallow aquifer.The other potential source of radionuclides to groundwater would be the areas where small volumes of condensate are vented to through steam traps to the ground surface. With the current monitoring well network, there is no indication that the small volume released to the ground surface has impacted groundwater quality.Groundwater data from the deeper aquifer show that there is no detectable tritium within the deeper aquifer.7.2.2 Database Management The analytical data are stored as both hard copy and electronically.

| ==SUMMARY==
| |
| This section provides a summary of the CSM for STPEGS. The geology below Units 1 and 2 consists of stratified interbedded sands and silts. The shallow groundwater is encountered at approximately 20 feet bgs and generally flows towards the southeast, towards the Colorado River.Within the shallow aquifer, there is a downward gradient between the upper and lower zone that could carry radionuclides released near the surface to deeper zones. Below the shallow aquifer, there is an aquitard of approximately 150 feet thick- This is underlain by a deeper aquifer that provides potable water to the plant.Groundwater flow velocity for the shallow aquifer is dependant on the gradient.
| |
| The sandier layers generally have a high horizontal hydraulic conductivity; however the gradient is very low, resulting in a very slow velocity-Within the deeper aquifer, groundwater is actively pumped to supply water for STPEGS. This pumping increases the horizontal gradient within the deep aquifer and therefore increases flow velocity and flow direction.
| |
| However, because there is approximately 150 feet of a clay and silt aquitard between the two water bearing zones, there is no measurable hydraulic communication between the shallow and deep aquifers.
| |
| Therefore, pumping of the deep aquifer does not appear to influence groundwater flow in the shallow aquifer below Units I and 2.Tritium is the only radionuclide detected in groundwater at STPEGS. There are two general sources for tritium to enter or be released to groundwater from the plant: 1) the MCR water infiltrating into the soils and underlying aquifer, and 2) releases from systems located within the protected area.By design, the MCR contributes low concentrations of tritiated water to the aquifer below. The MCR has had measurable levels of tritium for about 20 years, and first began to appear in relief wells about two years later. Extensive monitoring around the MCR completed in 2006 indicated that tritium migrated to a well about 700 feet west of the MCR as measured from the dike road.Wells about 750 feet north of the reservoir did not contain detectable tritium (<300 pCi/liter).
| |
| Wells within about 150 fret of the reservoir typically contained detectable tritium. This suggests that tritium may migrate about 700 feet per 18 years or about 40 ft'year. This is consistent with the UFSAR, Section 2A.13.3.1.2, where the migration rate is conservatively assumed to be about 77 0 ft/year (STPNOC, 2008b). Since the tritium concentrations in the MCR water are generally around 8-1 P:\Pr-ojects\5TP

| |
| Geologic boring logs from this location are not available, but this localized occurrence is most likely do to heterogeneities within the area where the well intersects a more transmissive zone.The second way radionuclides can be introduced to groundwater is from releases or leaks. Based on an evaluation of the systems, as well as a review of historic releases, the most likely source of tritium in groundwater is from releases from the TDS pipelines and from the steam and condensate that is discharged to the ground surface. For both of these lines, the initial source concentrations of tritium can range up to approximately 80,000 pCi/L and are most likely responsible for localized elevated concentrations in groundwater near MW-221C and E.Groundwater data from the monitoring network further supports this CSM_ No tritium concentrations in groundwater exceed the EPA MCL of 20,000 pCi/L, and tritium concentrations above background level have only been detected at well 221 C and 221 E, near a historic release from the Unit 2 TDS pipelines.
| |
| At these wells, elevated levels were first detected in the upper zone of the shallow aquifer (at MW-221C) and later from the lower zone of the shallow aquifer (MW-221E).Based on the site conditions, historic releases, and current data sets, there are a few areas where releases could have occurred and could be impacting groundwater that is not currently monitored-These data gaps include:* Areas east of the Unit I TDS pipeline (including areas downgradient from historic releases);" Areas downgradient from the condensate release areas; and" The deeper aquifer, below Units 1 and 2.By plant design, tritium has also been detected above background at wells located on the west side of MCR. Although these data are expected, this does present a data gap when defining the lateral extent of tritium detected in groundwater.

| ==9.0 CONCLUSION==
| |
| S This report has been completed to support NEI Initiative (NEI 07-07) and the implementation of the EPRI Guidelines for Groundwater Protection.
| |
| As such, the CSM was developed to document historic releases of tritium within the context of the local geology and hydrogeology to enable an assessment of potential impact of site operations, with respect to tritium, on groundwater quality.Although the CSM is an iterative process, the following conclusions are based on the data presented in this report-" Geology below the site is generally uniform, consisting of stratified, interbcdded silts and sands." Shallow groundwater contours indicated that groundwater generally flows slowly to the southeast, towards the Colorado River, with localized impacts ftom subsurface structures and groundwater mounding from the MCR." Deep groundwater flow is impacted by on-site pumping wells, however regionally groundwater will flow toward the south, southeast, towards Matagorda Bay.* There are approximately 520 piezometers and 35 monitoring wells around the MCR and 25 monitoring wells within the protected area of Units I and 2." Seven monitoring wells are sampled quarterly to evaluate groundwater quality.* The existing groundwater monitoring weUs near Units I and 2 provide adequate screening level data, but are not protected in accordance with industry (EPA and TCEQ) standards." With the exception of tritium, no other radionuclides have been detected in groundwater." Low concentrations of tritium have been detected in the shallow aquifer, but at levels well below the EPA MCL of 20,000 pCi/L. These values are also well below ODCM limit of 30,000 pCi/L.* Slightly elevated concentrations of tritium have been identified in the shallow aquifer west of the MCR and in the shallow aquifer adjacent to the Unit 2 TDS pipeline (as a result of a documented leak).* No radionuclides have been detected in the deeper aquifer or in samples collected from supply wells.* Based on a review of available data, it appears unlikely that radionuclides in groundwater (i.e. tritium) migrate past the facility property boundary in excess of regulatory standards.

| |
| In addition to these conclusions, the CSM has also identified the following data gaps: Low concentrations of tritium have been detected at MW-258, west of the MCR. To better define the lateral extent of detectable tritium in the shallow aquifer, additional groundwater monitoring should be conducted to understand the horizontal boundary of detectable tritium.Several releases have been documented from the TDS pipelines and associated tanks.Groundwater downgradient from the Unit 2 TDS pipeline has been evaluated, however there are no groundwater monitoring wells downgradient of the Unit I TDS pipeline.Small quantities of steam and condensate are vented to the ground surface via steam traps.There are no groundwater monitoring wells downgradient of the steam traps.Samples collected from the deeper aquifer have not detected radionuclides.
| |
| However, these samples were collected from the supply wells that are not only screened across large areas, but are also are pumped at high rates. By design, if any radionuclides did migrate to the deeper aquifer, samples collected from the supply wells would be diluted. With the current understand of the geology and the very low concentrations of radionuclides (tritium) in the shallow aquifer, it is not likely that radionuclides would migrate through the aquitard to the deep aquifer for the following reasons: 1) all tritium would decay by the time the groundwater migrated through the aquitard; and 2) any dilution be advection or dispersion would fbrther decrease the concentrations.
| |
| Should condition in the shallow aquifer changed significantly, additional investigations within the deep aquifer may be warranted.

| Groundwater Monitoring Network Recommendations:
| |
| Install six additional groundwater monitoring wells to supplement characterization of tritium impacted groundwater.
| |
| These explorations are summarized in Table 10-1 and are shown on Figures 10-1 and 10-2.Monitoring wells MW-801 through MW-803 should be installed to better characterize groundwater quality in the upper parts of the shallow aquifer immediately downgradient of the TDS pipeline and tanks for Unit 1. These wells should be installed with screens intersecting the water table.. Monitoring well MW-803 can also be used to monitor groundwater quality down gradient from the condensate steam traps.Monitoring well MW-804 will be installed within the deep aquifer, but only if radionuclide concentrations in the lower portion of the shallow aquifer exceed the ODCM criteria of 30,000 pCi/L.* Monitoring wells MW-805L/U will be advanced to monitor the upper and lower portions of shallow aquifer groundwater quality west of the MCR. The upper well will be installed to intersect the water table; the lower well will be installed at approximately 35 to 45 feet bgs, at a similar elevation as the existing well MW-258." Wells to be installed in the shallow aquifer may be installed using either hollow stem auger or casing drilling techniques." The well to be installed within the deep aquifer (MW-804) will only be installed when data suggest that there may be a plume migrating downward within the shallow aquifer. Because there is always a slight risk of cross contamination between aquifers, this deep well should only be installed when radioactivity measured in the lower portion of the shallow aquifer exceeds 30,000 pCi/L. This value is 1.5 times the EPA MCL,and is also equal to the NRC reporting criteria as documented in the ODCM.10-1 P.-ProjeC\STP

| |
| * Monitor existing groundwater wells within the protected area annually and monitor new wells semiannually.
| |
| If data indicate that a release has occurred then the frequency should be increased as warranted.
| |
| Groundwater Sampling Recommendations:
| |
| .Install dedicated tubing within wells that are sampled regularly to minimize the potential for cross-contamination.
| |
| 6 Install compression caps to wells completed with flush-mounted protective casing wells to minimize the potential for storm water runoff and other releases that may enter the well and impact the shallow aquifer.* Groundwater sampling techniques are adequate for collecting tritium samples however, should any other radionuclides or chemicals be included in the analytical suite, then additional samples should be collected using Low-Flow/Low Stress Groundwater Sampling (EPA, 1996)techniques.
| |
| * Collect groundwater samples from newly installed wells at a semiannual frequency for the first year, then if data do not indicate a release, annual sampling will be appropriate.
| |
| Should initial results indicate that releases have occurred or that groundwater is impacted by tritium at concentrations exceeding background values, additional wells may be installed to better delineate the plume and to identify potential sources.Because the current understanding of groundwater indicates that there are no immediate receptors downgradient, or a history of any groundwater samples exceeding the EPA MCLs, the schedule for installing these wells or modifying sampling techniques is not critical and can be prioritized as needed with ongoing groundwater investigations currently underway for Units 3 and 4.10-2 P:\Pwjects\STP

The documentation of the well installation is presented in Appendix F. Following the well installation and development, groundwater samples were collected and analyzed for tritium. These data are reported under separate cover, in the Annual Environmental Operating Report. As the data results further confirmed the CSM, no additional investigations are warranted at this time.The five wells installed under the Groundwater Protection Initiative have been added to STP groundwater monitoring program.P.\Projecm\sSTP

Full details of the mefthod and equipment he pro-poses to use for centering and holding the well pipe.2.3.2 The Contractor shall submit the following at the com-pletion of each hole: A complete soil log of each relief well boring and an as-built relief well installation sketch.2.4 GENERAL 2.4.1 Location The location, number and design depths of the wells will be ap-proximately as shown on the drawings.
| |
| The exact location and A-2998 10/. L/e6-2-15340300 Attachment 1 9Y510851018 Rev. I 6 depth of each well will be established in the field by the Resi-dent Construction Engineer (RCE). All wells shall have outlets as shown on the drawings.2.4.2 Disposal of effluents Water used for drilling, developing, and testing pressure relief.wells may be discharged into the Rain Cooling Reservoir (NCR)unless directed othervise-.
| |
| ---The Contractor shall use temporary piping to carry the effluents into the reservoir without causing erosion or damage to the embankment or other structures.
| |
| 2.4.3 2!EM of Well-The. design depths listed in the schedule indicate the approximate lengths of well screen and riser pipe required for each well.The well hole shall be drilled at least 2-feet deeper than the bottom elevation of the well screen. The top of the well screen generally will be placed at the top of pervious sand stratum.The actual depth to which the well shall be drilled and the lengths and spacing of slotted and unslotted pipe to be assembled for each well will be determined by the RCE in the field.2.4.4 Obstructions Encountered If obstructions are encountered in the foundation which are such as to render it impracticable to advance the drill hole to the design depth, the depth will be adjusted, if so directed, in order to utilize the well in the final system at the depth actually obtained.
| |
| The Contractor may be directed to abandon the well, plug the hole by backfilling with suitable material as prescribed in subsection 2.12.2 and construct another well at an adjacent site. Where obstructions are encountered, drilling shall be continued until it is demonstrated that further efforts to advance the drill hole are impracticable.
| |
| Such demonstration shall include, but not be limited to continuing drilling opera-tions when no gain in depth is being made for a minimum of 15 minutes. Wells which are abandoned because of impracticability of completion to the desired depth will be paid for to the extent specified in the contract.
| |
| Payment will not be made for the wells for which abandonment is necessitated by faulty operation or neglect of the Contractor.
| |
| | |
| ====2.4.5 Delay====
| |
| of Work In the event the Contractor is prevented from surging, developing and/or test pumping any well because the groundwater level is drawn down lower than the top of the well screen, work on that well shall be suspended, and shall not be resumed until the groundwater level has risen above the top of the well screen, in accordance with subsection 2.11.3.0 A-2998 10/28/86-3-15340300 Atttachment I 9y510B81018 Rev. I 2.5 WELL SCREM AND RISZR PIPE well screen and riser pipe shall be 6 inch inside diameter, flush joint, schedule 40 PVC pipe. The riser and screen section shall be joined with solvent cement meeting ASTH Standard D2564-80.The bottom of the well screen shall be plugged with a PVC cap cemented in place. Screen openings shall be uniform in size and pattern, and shall-be spaced approximately equally around the circumference of the pipe. The width of the slots shall be .050 I inch plus or minus 0.005 inch. The number of slots shall be such as to provide a total slot area of not less than 30 square inches per linear foot of screen.2.6 WELL FILTZR Naterial approved for the filter around the well screen and riser pipe shall be a washed sand composed of hard, tough, and durable particles free from adherent coatings.
| |
| It shall contain no vegetable matter nor soft, friable, thin, or elongated particles in appreciable quantities and shall meet the following gradation requ irements.U.S. Standard Percent Passing Sieve No. (ASTM D422-72) _b Weight 3/8 inch 100 4 90-100 8 70-90 16 30-55 30 10-25 50 0-10 100 0-3 Materials shall be uniformly graded between the limits specified above. All points on individual grading curves obtained from representative samples of filter material shall lie between the boundary limits as defined by smooth curves drawn through the tabulated grading limits plotted on a mechanical analysis dia-gram. The individual grading curves within these limits shall not exhibit abrupt changes in slope denoting skip grading, scalp-.ing of certain sizes or other irregularities which would be det-rimental to the proper functioning of the filter.2.7 WELL ACCBSS AND OUTLRTB Access and outlets for the pressure relief wells are addressed in Section 3.0. In general., the flow from each well will discharge onto concrete aprons as shown on the drawings.
| |
| The final top of the relief well riser pipe shall be set above the concrete back-fill as shown on the drawings.
| |
| A backflow check valve shall be installed on each well. The backflow check valve shall conform to the applicable provisions in Section 3.0.A-2998 10/28/86-4-15349300 Attachment 1 9Y510881 018 Rev. 1 2.8 DRILLING 2.8.1 General Wells may be drilled by the reverse rotary, bucket auger or other approved methods which will insure a properly formed hole suit-able for proper placement of the well screen, riser pipe and well filter.--Methods, which involve radical displacement of the forma-tion, or contaminate the pervious foundati-on, -will-not be per-mitted. Effluents shall be disposed of in accordance-with sub-section 2.4.2. During the drilling operation, 2 lbs of 70 per-cent Calcium Bypochiorite shall be added to the drilling fluid at the beginning of drilling.
| |
| The addition of Calcium Uypochlorite shall be done upon completion of the displacement of the fresh drill fluid. As the filter sand is placed in the hole, 70 percent Calcium Bypochlorite shall be added to evenly distribute a minimum of 2 lbs per ton of filter material placed.2.8.2 Reverse Method If the reverse rotary bmthod is used for drilling wells, all of the drilling fluid shall be removed from the filter and the nat-ural pervious formation.
| |
| If the walls of the hole above the top of the filter require support during surging operations, a tem-porary casing similar to that specified in subsection
| |
| | |
| ====2.8.3 below====
| |
| shall be placed so as to extend from the ground surface to at least 3-feet below the top of the filter. The diameter of the hole shall be such as will permit the placement of the minimum thickness of filter as specified in subsection 2.10. The drill-ing fluid shall be an approved suspension of fine-grained soil (not bentonite) and shall have the characteristic of being readily removable from the walls of the formation by surging or other approved methods.2.6.3 Temporary Casing Method Temporary well casing may be required to support the sides of the hole during drilling and placement of screen, riser pipe, and filter. The temporary casing shall have an outside diameter of not less than 18 inches, shall have sufficient thickness to re-tain its shape and maintain a true section throughout its depth, and may be in sections of any convenient length. The temporary casing shall be such as to permit its removal without interfering with the filter or well pipe. The Contractor may set the tem-porary casing by any approved method which will not displace the natural formation outside of the temporary casing. Removal of material from inside the temporary casing shall be done in a manner that will not disturb the material ahead of the casing.The water level inside the casing shall be maintained above the natural groundwatek level during installation of the casing. In the event the temporary casing should become distorteds the Contractor may be ordered to remove the distorted casing and A-2998 10/28/86-5-15340300 Attacbment 1 9Y510BS1018 Rev. 1 install a new casing at no additional cost. When temporary casing is used, it shall be carried to a minimum depth of 2-feet below the prescribed bottom elevation of the well screen.2.8.4 Samples The Contractor shall take soil samples for use in determining the depth at which the top of the well screen is to be set. Samples may be taken from the drilling fluid at the pump discharge if the reverse rotary method is used or they may be taken from the tools used in advancing the boring if other methods are used. The Con-tractor shall furnish the depth of the bore hole from which the sample is taken and shall furnish any other information available which may assist in determining the depth from which the sample was obtained or where any soil changes might have occurred.2.9 INSTAALLTION O RISER PIPE AND SCREEN 2.9.1 General All riser pipe and screen shall be in good" condition before in-stallation and all joints and accessory parts shall be securely fastened in place. The successive lengths of pipe shall be ar-ranged to provide accurate placement of the screen sections in the pervious strata. Particular care shall be exercised to pre-vent damage to the top of the riser pipe during installation and throughout all subsequent operations and any damage thereto shall be repaired at the Contractor's.expense.
| |
| After surging and pumping operations*
| |
| the top of the riser shall be finished as described In subsection 2.11.6. The riser pipe and screen shall be centered in the well and held securely in that position during placement of the filter by means of centering guides and a tremie holder, or other approved method.2.9.2 Installation The assembled riser pipe and screen shall be placed in the hole as indicated on the drawings and in such a manner as to avoid jarring impacts and to insure that the assembly is not damsged or displaced.
| |
| The riser pipe shall be held secure at the designated elevation during placement of the backfill.
| |
| Immediately after the installation of the well screen and riser pipe, the depth of the well shall be measured under the direction of the RCE. After the screen and riser pipe have been placed, a filter shall be constructed around the screen section as specified in subsection 2.10 and the well surged and pumped as specified in subsection 2.11.2.9.3 Alignment Each completed well shall be' reasonably straight and plumb. A variation of 6-inches will be permitted in the alignment of the A-2998 10/28/86-6-! S340300 Attachment

| ?9¥510881018 Rev. I combined riser pipe and screen from a plumb line from the top of the well; however, this will not relieve the Contractor of the responsibility of maintaining adequate clearance for installation of the bailing, surging and pumping equipment required for test-ing the wells.2.10 PL&AEBEWT OF WDAL FILTER ell filter shall not be placed- in the hole before the nell screen and riser pipe are installed.
| |
| After the well screen and riser pipe have been installed, well filter shall be tremied to the bottom of the hole, in an approved manner, so that no sig-nificant segregation will occur. bhe filter shall have a minimum thickness of 6 inches between the outside of the well screen and the natural formation, and shall be placed to the required elevation as determined by detailed requirements at the time the vell is installed.
| |
| At the start of operations, the tremie shall rest on the bottom of the hole and be filled with well filter.After the operation is started, the elevation of the well filter in the treaie shall be kept above the fill in the vell at all times. -If a temporary casing is used, the well filter shall be placed in increments not to exceed two feet; the tremie and casing shall then be raised in increments equal to the increments of well filter placed, except that at no time prior to completing the operation shall the bottom of the temporary casing be less than one foot below the top of the filter. The alternate placing 4 of well filter and withdrawing of temporary casing shall be con-tinued until the well filter has been placed to the required elevattion.
| |
| 2.11 DEVELOPMNET OP WELL 2.11.1 General Within 4 hours after completion of the placing of the well fil-ter, material which may have entered the well during the placing operation shall be removed, and development of the well shall be commenced so as to achieve a stable well of maximum efficiency.
| |
| Development of the well shall consist of surging and pumping as hereinafter specified.
| |
| The method and amount of surging and pumping considered necessary to develop the well shall be ap-proved. Effluents shall be disposed of in accordance with subsection 2.4.2.2.11.2 Surging Within 4 hours after installation, the well should be pumped for at least 30 minutes. Development of the well should be started within 12 hours. after the well has been pumped. The well shall be developed by surging with a smooth-fitting double surge block while simultaneously pumping the space between the packers with air, or a auction pump, so as to draw fresh water through the A-2998 10/28/86-7-1534Q300
| |
| .o o *Attachment 1 9Y510BSlO5I Rev. I screen and filter simultaneously with the surging operation.
| |
| The surge block shall be raised and lowered at a rate of about 2 ft/sec. The well will be surged for not less than 1 hour. The amount of material deposited in the bottom of the well shall be determined after each cycle (about 15 trips with the surge block per cycle). Surging shall continue until the accumulation of material pulled through the well screen in any one cycle becomes less than 0.1 foot. The well screen shall be cleaned with a bot-tom-suction pump, or a suction pump with a hose extending to the bottom of the vell when the accumulation of material in the bot-tom of the well becomes more than 1 foot at any time during surg-ing. All material in the bottom of the well shall be removed at the end of the surging operation.
| |
| Material pumped from the well shall be visually inspected to see if any foundation sand or silt is being removed.2.11.3 Pumping Tests 2.11.3.1 General Upon completion of installation, surging and development pumping, and before final acceptance, each veil shall be subjected to a pumping test. The test pumping and sand infiltration tests here-inafter specified shall be performed before placement of the con-crete backfill prescribed in subsection 2.12. The pumping rate shall be adjusted by the Contractor so that the water level in the well is at all times above the top of the uppermost veil screen. In no event shall the pumping tests be performed when the water level in the well is drawn down to a point lower than the top of the well screen. In such cases the test shall be suspended and shall not be resumed until the groundwater table has risen above the top of the well screen and the Contractor has received approval to proceed. Prior to commencement of the pump-ing test, and again after completion of the test, the depth of the well shall be measured, under the direction of a representa-tive of the RCE.2.11.3.2 Equipment A. Pa The Contractor shall provide a pump capable of producing the specified drawdown over a period of time sufficient to satisfac-torily perform the pumping test specified.
| |
| The use of deep vell pumps will be permitted provided that the pump itself is kept within the riser pipe, and the Contractor demonstrates that all specified requirements of pumping and sand measurement can be complied with.

| |
| 2.5.3.3 Monitoring Equipment The equipment used for obtaining the standpipe piezometer measurements shall consist of a down-hole probe unit connected by an electric cable to an ohmmeter-type gauge. Submergence of the probe's bare electrodes beneath the water level in the piezometer activates the readout unit.The equipment used for obtaining the pneumatic piezometer measurements consists of a portable readout unit whuch, when connected to tubes attached to the pneumatic transducer, will give a direct readout of embankment hydrostatic pressure at the transducer location.-9-4634a/O135a 9Y510YS1004 Rev. 6 2.5.3.4 Monitoring Procedures A. Standpipe P ezometers 1. To obtain a measursent at the field'installation, probe shall be lowered into the standpipe until a signal is obtained at the read-out.
| |
| The depth Is to be read to the nearest 0.1 foot-t and recorded.
| |
| ... ...2. Step 1 shall be repeated by raising probe several feet and reloaering, and data shall be recorded on the form.3. Until two measurements within 0.1 foot of each other are obtained, Step 2 shall be repeated.4. Cap on standpipe shall be replaced after the probe is removed.S. Average of two or three measurements (as the case may be)for each standplpe plezometer shall then be entered in the"Readingso column on Reservoir piezometer data form (Fig.9). Data shall be recorded to the nearest 0.1 foot.B. Pneumatic Piezometers These remote sensing devices consist of two tubes leading from an observation station connected to two openings in the cell body. Hydrostatic pressure exerted on the cell causes the diaphragm to close. The procedures outlined below permit a measurement of embankment hydrostatic pressure to be made by allowing nitrogen to be introduced by one tube until the pressures on both sides of the diaphragm are balanced thus allowing air to return to the observation station through the second tube.1. Check zero setting on Output Pressure guage with Transfer and Vent valves open. If adjustment is required, release pressure within the gauge (i.e.. leave valves open), carefully move the glass lens cover, and turn the recalibrater screw until the pointer resets at zero.2. Close all the valves on the Pneumatic Pressure Indicator.

| Each cycle of readings (and every second cycle during initial filling) shall coincide with a cycle of relief well flow readings.2.5.3.6 Reporting When plezometers are installed, the initial data shall be reviewed and the readings taken before the instrument stabilizes need not he reported.
| |
| The piezemeter data shall be reported to Site Engineering Manager on the Reservoir Piezometer Data forms for the standpipe and pneumatic piezometers (Figures 9 and 12 respectively) and transmitted to the SEN using the Data Control Form (Figure 7).2.5.4 Relief Wells 2.5.4.1 Introduction Relief wells have been installed around the downstream perimeter of the Main Cooling Reservoir embankment to relieve foundation hydrostatic pressure in the permeable soil layers beneath the embankment.
| |
| The relief wells are free-draining and self-contained.
| |
| The monitoring specified herein consists of the periodic measuring of the rate (volume per unit of time) of water flow from the discharge pipe of each flowing well.The location of relief wells are tabulated In Table 4 by their station number along the Main Coollng Reservoir embankment. 4634a/0135a 9Y510YSlO04 Rev. 6 2.5.4.2 eonitorfng Procedures Flow from relief wells shall be measured using a graduated container and stopwatch.
| |
| The flow shall be measured without raising the flap valve at the end of discharge pipes. However for the next (after Novmber 25, 1985) two cycles of monitoring, the rate of flow from the relief wells shall also be measured after raising the flap valves and allowing the flow to stabilize to a steady stream. Flowrate can be measured in any unit, but in all cases the readings shall be converted to and reported in gallons per minute (g9p). The effluent shall be visually checked for fines by holding the container against light. A qualitative coment (e.g., highly turbid, lightly turbid, or clear)shall be noted on the form. If silt is present in the discharge pipe due to drainage ditch flooding.
| |
| it shall be so noted. The flow shall be measured at least twice to achieve repeatabilit.
| |
| The rate of flow, or if not flowing, an appropriate note, e.g. "DRY, "UNDER WATER," "INACCESSIBLE," shall be recorded on Relief Well Flow Report (Figure 10). Water level in the Reservoir at the time of monitoring relief well flow shall also be noted on the Flow-Report Fem.The Contractor may, at his discretion, but with prior written notification to Bechtel, use alternate monitoring pmcedure(s) for relief wells that are accessible, but may have their discharge pipes tenporarily underwater.
| |
| 2.5.4.3 Frequency of Monitoring The rate of flow from relief wells shall be measured at the frequencies indicated in Table 1. Readings shall be taken in a manner so that all relief well flows are read within one working week. Schedule of relief well readings shall be coordinated with piezometer readings as specified above in 2.5.3.5.The metallic relief well discharge flap valves (pre-1981) shall be inspected on a monthly basis.2.5.4.4. Reporting The relief well data shall be reported to the SEN on the Relief Well Flow Report Form (Figure 10) and transmitted under the Data Control Form (Figure 7).2.5.5 Inclinometers 2.5.5.1 Introduction Inclinmeters have been installed at selected stations on the Maln Cooling Reservoir embankment to monitor horizontal ground movement at those stations.Each of the monitored stations have three inclinoeters
| |
| -one at the embankment crest, one on the upstream face at an approximate elevation of 50 feet, and the third one on the mbarcument dowstrem bern.~-13-I 4634a/0135a 9YSlOYS1004 Rev. 6 2.5.5.2 Location The inclinometer sets are located at approximately Stations 262 + 00, 280 + 00, 318 +.20 and 341 + 50 of the Rain Cooling Reservor tabulated by their numbers in Table 5.2.5.5.3 Method of Measurement The inclinmeter sensor, referred to as a torpedo, is moved through the permanently installed aluminum or plastic casing along four internal longitudfnal grooves which guide the torpedo. Variations detected by the tilt sensor show on a portable indicator and are read and recorded.Procedures for performing inclinometer measurements shall be as follows: A. The groove or slot orientation shall be recorded.
| |
| The slots are designated as A+, A-, B+, and 8- as shown on Figure 6.B. Wi1th the inclinometer sensor, cable and readout unit connected, the torpedo is lowered with its upper wheel in the A+ groove (for a biaxial device this will give inclinations for the A+ and B+ directions).
| |
| C. The torpedo is then lowered to a reference point established during calibration.
| |
| The cable may be fixed by an extension cable clamp while awaiting stabilization of the readings on the indicator unit. Once stabilized, the complete readings are reorded.0. The cable is then pulled up 2 feet, and another reading taken.Readings are continued in tris manner at 2-foot incrments until the top of the casing is reached.E. After reaching the top of the casing the torpedo is removed and rotated 180 degrees then is inserted back Into the grooves (upper wheels In the A- groove). The instnument is then rea4y to record the inclination with respect to the A- and B-directions.
| |
| F. The procedures outlined in steps B through D shall be repeated.2.5.5.4 Frequency of Monitoring The Inclinometers shall be monitored at the frequencies indicated in Table 1.-14-4634a/0135a 9Y15 OYS1004 S Rev. 6 2.5.5.6 Reporting The inclinometer readings shall be reported to the Site Engineering Manager on the Inclinometer Data Form (Figure 11), and transmitted under the Data Control Form (Figure 7).2.6 RECORDING OF READINGS 2.6.1 General Readings shall be entered by the Contractor's field personnel on the forms as specified herein, and recorded on hand held Input devices at the discretion of the Contractor.

| The Materials Degradation Master Matrix (MDMM). EPRI, Palo Alto, CA: 2007 1016235.lif PRODUCT DESCRIPTION Experience at numerous operating and decommissioned commercial nuclear power plants (NPPs) has positively identified unintentional releases of small quantities of radionuclides from plant structures.
| |
| Component, system, and structural integrity failures have ultimately led to unmonitored activity being released to both the site and local environment.
| |
| This, in turn, has resulted in a major challenge to utilities in identifying and controlling such sources, and in remediation and monitoring of groundwater and environmental contamination over the life of the plant. A Materials Degradation Matrix (MDM) is needed to assist in groundwater protection and degradation management.
| |
| The first step in formulating the MDM is documented in this report, with development of a Materials Degradation Master Matrix (MDMM), listing 100 degradation mechanisms impacting buried components.
| |
| Results & Findings The MDMM is a summary of all possible degradation mechanisms for the materials being O evaluated.
| |
| Included are those used in the construction and fabrication of buried piping, storage tanks, sumps and spent fuel pools. These components possess a high potential to leak radionuclides into groundwater based on industry experience, and thus present the greatest concern.The MDMM is a valuable tool for use as a "first screen" for the determination of potentially operative degradation mechanisms for buried components.
| |
| Its primary virtues lie in its relative ease of use, the conservative nature of the logic employed, and the comprehensive list of degradation mechanisms evaluated.
| |
| Challinges
| |
| & Obn tve(s)At present, additional EPRI support is needed for long-term implementation of industry groundwater protection programs, with emphasis on prevention and effective remediation.
| |
| One aspect of effective prevention is to improve materials reliability for buried piping, storage tanks, sumps, and spent fuel pools that have the potential to leak radioactive materials into the groundwater.
| |
| Improved materials" reliability will lead to more effective leakage prevention.
| |
| A necessary step in achieving this goal is to understand material degradation mechanisms for the systems and components of concern. This will be accomplished through a comprehensive MDM focused on the materials and conditions critical to groundwater proection-The objective of this project was to take the first step toward the MDM by developing the MDMM.Applications, Values & Use The creation of the MDMM endeavors to help system owners by giving them a tool to focus A, resources on those buried piping components that are most susceptible to material degradation v
| |
| and may pose a groundwater contamination risk. Such a matrix will ultimately help NPP owners O focus resources on buried (as well as selected aboveground) components susceptible to material degradation and posing a groundwater contamination risk.EPRI Perspectve Best practices in low level waste (LLW) management serve not only to enhance environmental and public acceptance of nuclear power, but also to optimize utility costs as well. Long-term research and development is critical to address a number of current industry LLW issues, such as groundwater contamination.
| |
| EPRI hopes that continued development of the MDMM, along with other related initiatives under the EPRI Groundwater Protection Initiative, will help owners to eventually develop inspection and/or mitigation programs for comprehensive life-cycle management of these critical components.
| |
| Such groundwater protection guidance should reduce regulatory risk and improve public perception through the development of safe and efficient contamination risk management strategies.
| |
| Approach The nuclear power industry has undertaken a Groundwater Protection Initiative at the Direction of the Nuclear Energy Institute (NEI) Nuclear Strategic Issues Advisory Committee (NSIAC).This initiative makes provision for essential technical guidance to utilities on the necessary elements of a sound groundwater protection program. Investigators modeled the MDMM after the American Society of Mechanical Engineers (ASME) screening table for materials degradation.
| |
| It was designed to serve as a conservative "first screen" for all possible degradation mechanisms, including those with no known NPP history. Not included in the MDMM are data on mechanism rates, load characteristics, barrier thicknesses, or time to failure evaluations.
| |
| What* the MDMM does provide ar susceptibility criteria for a total of 100 degradation mechanisms that could potentially affect buried components--33 general corrosion mechanisms, 9 erosion/wear mechanisms, 4 fatigue mechanisms, 8 localized corrosion mechanisms, 4 embrittlement mechanisms, 11 metallurgical/material effect mechanisms, 10 environmentally assisted cracking mechanisms, 3 high-temperature mechanisms, and 18 types of fabrication defects. The goal was to be as thorough as possible in listing all possible mechanisms as well as the associated criteria.
| |
| Mechanism susceptibility was evaluated as potentially operative or non-operative, and was based upon the materials of construction, the internal and external environment, operating conditions (temperature, flow rate), and the nature of any loading (static, dynamic, or thermal).Keywords Groundwater Protection Initiative Materials Degradation Master Matrix (MDMM)Materials Degradation Matrix (MDM)Groundwater Contamination Material Degradation Mechanisms Low Level Waste vi CONTENTS 1 INCTRODU1O P .-.n -.e.... ~............

| | |
| ===1.1 Background===
| |
| Experience at numerous operating and decommissioned commercial nuclear power plants (NPPs) has positively identified unintentional releases of small quantities of radionuclides from plant structures.
| |
| Component, system, and structural integrity failures have ultimately led to unmonitored activity being released to both the site and local environment-This, in turn, has resulted in a major challenge to utilities in identifying and controlling such sources, and in remediation and monitoring of the contamination over the life of the plant.The level of effort required for monitoring and/or recovering of structures, soil, and hydrogeological formations due to tritium and other radioactive contamination is very significant
| |
| .and costly. A standardized approach to groundwater control will aid in optimizing both the effort and costs of an environmental monitoring process.EPRI is providing technical support for the Industry Groundwater Protection Initiative, approved by the Nuclear Strategic Issues Advisory Committee (NSIAC) in 2006. Undocumented releases of tritium and other nuclides from existing nuclear power plants (NPPs) have resulted in significant negative public and regulatory pressure to correct this problem for both operating and future nuclear plants. The Nuclear Energy Institute (NEI) has successfully implemented interim guidance to the industry for implementing the Groundwater Initiative
| |
| [NEI 07-07] which describes the communications protocol and the general features of a groundwater monitoring program. The EPRI Groundwater Protection Guidelines
| |
| [EPRI Report 1015118] provides further detailed technical guidance to the industry for implementing a groundwater monitoring program.Current activities in Groundwater Protection have been focused on producing a set of EPRI guidelines which provide the basis for a successful and optimized groundwater monitoring O program. However, there is currently a gap in the EPRI support needed for the long term I-1 INTRODUCTON implementation of the industry groundwater protection program& Longer term efforts need to* focus on prevention and effective remediation.
| |
| One aspect of effective prevention is to improve materials reliability for the buried piping, storage tanks, sumps, and spent fuel pools that have the potential to leak radioactive materials into the groundwater.
| |
| Improved materials reliability will lead to more effective leakage prevention.
| |
| A first step in achieving this goal is to understand the degradation mechanisms of the materials of the systems and components of concern through the development of a comprehensive materials degradation matrix (MDM) focused on the materials and conditions critical to groundwater protection.
| |
| Such a matrix wiU help NPP owners focus resources on buried (as well as selected above-ground) components susceptible to material degradation which pose a groundwater contamination risk, as well as assist in developing inspection and/or mitigation programs for life-cycle management of these components.
| |
| The development efforts on these inspection and/or mitigation programs are aimed at: 1) Assisting with defining standards for the development of a robust nuclear plant groundwater protection program that will define routine monitoring and characterization of the hydrogeology as well as groundwater quality at a reactor site.2) Provision of a framework for NSSS vendors and future operators of commercial NPPs that will reduce the potential for unplanned radioactive releases.
| |
| Such a framework is in accord with lO.CFR20.1406, "Minimization of Contamination," which stipulates that "design and operating procedures will minimize, to the extent practicable, contamination of the facility and the environment..." for new plants.1.2 Objectives The overall objective of this effort is to develop a detailed materials degradation matrix (MDM)for materials associated with groundwater protection.
| |
| This present work represents the first step in this effort, which is the development of a Materials aDegradation Master Matrix (MDMM). The MDMM is a summary of all possible degradation 1-2 INMDUCTION mechanisms for the materials being evaluated.
| |
| These include those used in the construction and O fabrication of buried piping, storage tanks, sumps and spent fuel poolsh These components possess a high potential to leak radionuclides into groundwater based on industry experiences, and thus present the greatest concern.1-3 0 2 MATRIX DEVELOPMENT AND DESIGN INPUTS The Materials Degradation Master Matrix (MDMM) was modeled after the ASME screening table for materials degradation
| |
| [IJ. It was designed to serve as a conservative "first screen" for all possible degradation mechanisms including those with no known history at NPP. The MDMM does not include data on mechanism rates, load characteristics, barrier thicknesses, or time to failure evaluations.
| |
| The MDMM, shown in Appendix A, was designed to include susceptibility criteria for a total of 100 degradation mechanisms that could potentially affect buried components'.
| |
| The goal was to be as thorough as possible in listing all possible mechanisms as well as the associated criteria.The degradation mechanisms listed include: e 33 General Corrosion mechanisms Acid Dew Point Corrosion Ammonia Grooving Amine Corrosion Caustic Corrosion (Caustic Gouging)Chelant Corrosion CO, Corrosion Corrosion Under Insulation (CUI)DISOved 0O Attack EroskoVCorrosion Filiform Corrosion Flow-Accelerated Corrosion (FAC)Flue Gas Dew Point Corrosion Fuel Ash Corrosion Galvanic Corrosion Graphitization High Temp HJH 2 S Corrosion Hydrochloric Acid Corrosion High Temp H/-IS Corrosion Hydrochloric Acid Corrosion Hydroflouric Acid Corrosion Uquid (Molten) Slag Attack Napthenic Acid Corrosion General Corrosion High Temperature Oxidation Phenol (Carbolic Acid)Phosphate Attack Phosphoric Acid Corrosion Selective Leaching (Dealloying of Metals)Selective Leaching of Concrete (e.g..Carbonati)

Those mechanisms falling under the category of manufacturing defects were also color-coded (lavender).
| |
| The MDMM logic was arranged such that an "X" (indicating the specific criterion was met) or an "N" (indicating the specific criteria was not a requirement) must exist in all applicable fields for each degradation mechanism to be considered potentially operative.
| |
| Thus, starting from the material of choice, the user would then go down the table for a list of possible active mechanisms.
| |
| Each mechanism would then be scrutinized (horizontally), checking that there is an "X" in the field for each of the environmental conditions of the component being screened.
| |
| A single blank space (no "X") invalidates the mechanism being scrutinized.
| |
| Versions of the materials degradation matrix were generated for each type of buried component; buried piping, storage tanks, sumps and spent fuel pools. Each component specific matrix contains only the materials, criteria and degradation mechanisms potentially operable for that component, and allows for a more focused approach in evaluating mechanisms on a component specific basis. These component matrices are also included in Appendix A.
| |
| PILOT STUDY 3 PILOT STUDY 3.1 Identification of Plants for Pilot Study In order to test the practicality of the MDMM, a number of plants were identified as potential sources of data on buried components.
| |
| In selecting plants, an effort was made to include both main reactor types (BWR and PWR) and a variety of NSSS vendors (B&W, CE, Westinghouse and GE). Aside from these criteria, plants were selected based upon the ease with which data could be obtained quickly (due to the short duration of the work), either by virtue of good plant contacts or prior buried piping work performed.
| |
| This process resulted in the majority of data being collected for Westinghouse PWRs, primarily since buried piping information for many of these plants had been previously obtained.
| |
| Only one BWR was able to provide information on the required schedule, hence the low BWR sampling.
| |
| The selected plants included: " Arkansas Nuclear One (ANO) Units l&2 (B&W and CE, PWR)* South Texas Units l&2 (Westinghouse, PWR)" Byron Units l&2 (Westinghouse, PWR)" Dresden Units 2&3 (GE, BWR)" Diablo Canyon Units l&2 (Westinghouse, PWR)" Comanche PeakUnits l&2 (Westinghouse, PWR)" Wolf Creek (Westinghouse, PWR)" Callaway (Westinghouse, PWR)3.2 Inventory of Components Evaluated Data was collected for 1) buried piping, 2) storage tanks, 3) sumps, and 4) spent fuel pools. Data for all four component groups was collected from ANO and South Texas only. Only buried piping data (pipe and fittings, welds) was available from the other NPPs. Only data for the major passive buried components was obtained.
| |
| As such, no data was collected on valves, vacuum 3-6 PILOT STUDY breakers or any other active components in these systems. Data collected included construction and fabrication material type, temperature, flow rates, internal and external environments, and loading information.
| |
| | |
| ===3.3 Limitations===
| |
| | |
| Associated with Plant Data Collection Data quality was limited by the incomplete nature of the available design and service history of the components in question.
| |
| This was due to a variety of factors, including the fact that the components were not typically safety-related, associated data was often spread across a number of systems and system managers, and root cause evaluations were seldom performed (or if performed, inadequate).
| |
| Loading data in particular proved difficult to obtain, and ended up being excluded from the scope of the evaluation.

| |
| .4 EVALUATION AND RESULTS 4.1 Data Summary The data on all buried components obtained from ANO and South Texas, as well as the buried piping data obtained from the other NPPs, has been summarized in Tables 4-1 through 4-5 according to material, temperature, flow rate, process fluid, and external environment, respectively.
| |
| The data collected for the pilot plants was used to verify that the MDMM criteria covered all materials, operating conditions and environments existing in the plants. Where criteria were initially lacking in the MDMM, but present in the data, new criteria were added to reflect actual conditions.
| |
| This process ensured that the MDMM was comprehensive for the purposes of the* pilot study.Common buried piping materials include carbon steel, stainless steel, polyvinyl chloride (PVC), ductile iron, and galvanized steel. Carbon steel, stainless steel and concrete were most common for storage tanks, while sumps and spent fuel pools were typically concrete with a Stainless steel liner. Most buried components operated at ambient temperature; however, there were some high-temperature exceptions in certain buried piping systems (such as a 160 *F (71 C) operating temperature in the Condensate Storage and Transfer System and a 325 ¶F (163 "C) operating temperature in the Service Air system, both at South Texas). A wide range of flow rates and flow conditions were encountered in buried piping, while other buried components (tanks, sumps)typically encounter intermittent or stagnant flow conditions.
| |
| Buried components encounter numerous process fluids, making for a wide range of internal environments.
| |
| Those process fluids known to pose a groundwater contamination risk include radiologically-contaminated water, diesel fuel oil, condensate polisher regeneration discharge, water (with acid, caustics, and/or sodium), organic and inorganic chemical waste, sodium hypochlorite.
| |
| hydrazine, butane, hydrogen gas, gasoline, natural gas, lubricants, and oily waste.4-1 FA'ALUJAION AND RESUM7 4.2 Data Evaluation and Analyses Using the MDMM* The specific combination of material, temperature, flow rate and internal and external environment for each buried component was separately run through each of the 100 mechanisms of the MDMM. Where data for a certain criterion was unknown or unclear, the most conservative assumption was used. The result was an associated list of degradation mechanisms that were potentially operable for each buried component.
| |
| As might be expected, the number of active mechanisms ranged widely, depending upon each particular set of conditions, but on average around 25 of the 100 total mechanisms were determined to be operative for each case. A more detailed screening process will be required to narrow the number of possible operative mechanisms down to a few based on probability, rates, etc. Such a screen is beyond the capability of the MDMM which is intended to be a "coarse" screen. Better screening will be achieved in the course of developing the MDM.4.3 Comparison to Inspection and Failure Data An additional objective of this evaluation was to use actual plant service history inspection and O failure data to validate the MDMM logic. The primary obstacle to this approach was that few plants have comprehensive and effective inspection and groundwater protection programs.Therefore, it is often the case that data regarding buried components is often scarce, and can be spread across many systems managed by different individuals.
| |
| In addition, since buried components are typically non-safety related equipment, root cause analyses (RCA) of failures ame seldom performed.
| |
| Instead, the component or affected area is patched or replaced and returned to service. Even in those rare cases where they are performed, the RCA often do not rigorously evaluate the physical evidence and other related factors to properly diagnose the cause(s) due to budgetary constraints and other issues. The factors cited lead to the conclusion that, even when failures are recorded and RCA performed, data on present component condition is often lacking.In addition, attention to mitigation approaches (e.g., cathodic protection) was generally poor, and also considered low-priority in budgeting.
| |
| Despite these challenges, some service history failure data was obtained for ANO buried components.
| |
| The systems with known failures were primarily Fire Water and* Domestic Water. There were also a small number of failures in the Compressed Air, 4-2 EVAUJATION AND .MULTS.High Pressure Nitrogen, Diesel Fuel and Fuel Oil systems. The documented failures include leaks, failed hydrotests, corrosion/debris plugging and sludge buildup. The root causes of failure were seldom established.
| |
| It was therefore not considered a useful exercise to compare these failures to the active degradation mechanisms predicted for these buried components by the MDMM other than to confirm that the MDMM was sufficiently thorough to have included the mechanisms identified for those components.
| |
| A larger plant study is necessary in order to gather enough data to compare active plant degradation mechanisms to those predicated by the MDMM.4-3 w w 14 Table 4-1.

| |
| Its primary virtues lie in its relative ease of use, the conservative nature of the logic employed, and the comprehensive list of degradation mechanisms evaluated.
| |
| SI recommends that the MDMM be made even more valuable by pursuing the initiatives discussed in Section 5.2.5.2 Future Development The usefulness of the MDMM can be greatly enhanced through several related follow-on initiatives described below" Indicating on the MDMM those degradation mechanisms with either a known history or logical credibility in a NPP environment.
| |
| A larger plant study (than the pilot) is required for this purpose." Developing additional "finer screens" (of single or multiple levels) for all degradation mechanisms to render a more definitive and quantitative judgment on potentially operative degradation in order to provide guidance in determining the approach to characterize and/or mitigate the mechanism" Developing an Expert System to automate the screening process (user would simply enter information on material, environment, operating conditions, and loading, and the expert system would run multiple screening determinations for all mechanisms and determine the final list of potentially active mechanisms)" Collecting and evaluating data on mechanism rates, load magnitudes and frequencies, and barrier thicknesses so that time to failure can be evaluated 5-1 CONC LISIONS AND RECOMMENDA77ONS 5.3 Longer-Term Goats Thw creation of the MDMM *endeavors to help system owners by giving them a tool to focus resources on those buried piping components that are susceptible to material degradation and may pose a groundwater contamination risk. It is the hope that continued development of the MDMM, along with other related initiatives under the EPRI Groundwater Protection Initiative, will help owners to eventually develop inspection and/or mitigation programs for comprehensive life-cycle management of these critical components.

| -CIRCULATING WATER (CW) and AUXILIARY COOLING WATER OPEN LOOP (00 BURIED PIPE -CR 07-9083-5 and 7 CIRCULATING WATER The Circulating Water System provides cooling water to the Main Condensers for removal of heat to the Main Cooling Water Reservoir (MCR). 3 or 4 pumps are in service (per Unit) with each rated at approximately 225,000 gpm. The piping is made up of 84" (located in the Turbine Building), 96" and 138" (located above and below ground level) pre-stressed concrete cylinder pipe.The normal failure of this type pipe is a rupture (fish mouth). Most likely a failure will be visually observed.However if the failure occurs on the supply side to the condensers the Control Room will also get an indication of a plant anomaly due to a change in condenser vacuum or a change in pump discharge pressure.OPEN LOOP The Open Loop System provides cooling water from the MCR to the ACW OC/Closed Loop Heat Exchangers, Non-Essential HVAC Chillers, Steam Generator Feedwater Pump/Turbine Lube Oil Coolers, Main Turbine Lube Oil Coolers and Generator Hydrogen Coolers. Normal Unit configuration has 2 pumps in service, each rated at approximately 11,900 gpm. The buried piping is made up of 30", 24", 18", 16", 14" and 10" diameter pre-stressed concrete cylinder and pre-tensioned concrete cylinder (bar wrapped) pipe.Liquid Radwaste is discharged to the MCR through the Non-Essential UVAC Chillers OC Return Line.All Open Loop is returned to the MCR through the CW piping.The normal failure of this type pipe is a rupture (fish mouth). Most likely a failure will be visually observed.However if a failure occurs on the Control Room will get an alarm indicating a loss of discharge pressure.MATERIAL CONDITION A Life Cycle Management Study was conducted for the CW and OC Buried Pipe in 2002/2003.
| |
| The following provides a discussion of the findings and the current status.* The Circulating Water and Auxiliary Cooling Water Open Loop Pipe have 9 failure mechanisms that can be categorized into seven. The seven are conrosion, soil composition (sulfate, chloride and acidic), atmospheric exposure, stray current corrosion, galvanic corrosion cell, differential aeration cell and hydrogen induced cracking (cathodic overprotection).
| |
| * Stray Current and Galvanic Corrosion Cell were determined not to be a potential problem.* We had no data on the soil composition, atmospheric exposure, and differential aeration cell corrosion (applies only to Circulating Water).* There was data that showed that we had over impressed the cathodic protection current for about one-year in 1995.The following activities have been conducted to determine the condition of the pipe. Also the status has been provided.ATMOSPHERIC EXPOSURE (Resolved)
| |
| This failure mechanism exists for both CW and OC pipe that is exposed to the atmosphere and is located from the intake structure until the pipe enters the ground on the outside of the Main Cooling Reservoir embankment.
| |
| It also exists for CW piping again where it penetrates the ground on the outside of the embankment on the return side until it reaches the reservoir water.
| |
| * The Carbonation analyzes of the OD concrete revealed very little degradation and is considered satisfactory.
| |
| The recommended action is to develop an inspection PM and implement every 12 years. 04-10730-5, COMPLETE 2/20/05. PM 05436 DIFFERENTIAL AERATION CELL (Resolved)
| |
| -Circulating Water ONLY The Differential Aeration Cell exists at the splash zone where the pipe and the reservoir water interface.
| |
| * The carbonation levels ranged from a pH of 11.5 to 12.0 which is considered negligibly corrosive.
| |
| The water soluble chloride concentration indicated a low potential for degradation of the concrete or corrosion of the pre-stressed wire. 04-10730-16, COMPLETE 5/17/07. PM 05436 SOIL DEGRADATION (Resolved)
| |
| The required action lo protect the pipe from soil degradation is to maintain the cathodic protection system within the required parameters.
| |
| Currently the cathodic protection system is performing as required to protect the Buried Pipe.CORROSION ISSUE (Resolved)
| |
| Because of the size of the OC Pipe a visual inspection of the ID was not conducted and the above ground ID joints have the same material as the Circulating Water pipe. Based the inspection of the above ground OD CW Pipe joints the OC joints are considered acceptable.
| |
| The industry standard for joint material is Portland cement (the free lime (pH) in Portland cement passivates the carbon steel components and prevents corrosion).
| |
| We have joints that have joint material other than Portland cement.During 2RE12, t-Unit 2 138" OD and I- Unit 2 96" IDjoint were inspected.
| |
| The 138"joint was filled with an oil based product called Ram-Neck and showed no signs of deterioration.
| |
| The 96"joint material was determined to be Tex-O-Flex.
| |
| This material holds water and was originally impregnated with Portland cement. The joint material, which had rust bleed from it, was removed and the steel parts were found to be in satisfactory condition.
| |
| As a result of these inspections our consultant provide inspection criteria and thd initial inspection are underway.HYDROGEN INDUCED CRACKING (Analysis is underway)The Eddy Current Inspections of the Circulating Water Pipe were completed during I RE12 and 2RE I1. The data collected from this inspection will also be used for evaluating the Open Loop Pipe. The inspection method requires traversing the pipe and the Open Loop Pipe is too small a diameter and due to our piping configuration technology does not exist to perform this type of inspection in OC.The firm of Simpson, Gumpertz and Hager (SGH) of Boston, MA has reviewed the Eddy Current data and has recommended flrther examination of the pipe. System Engineering is in the process of developing a Plan of Action and obtaining funding to perform this next step. Once the visual inspection of buried pipe is completed a repair/replacement plan will be developed and implemented.
| |
| MAINTENANCE AND INSPECTION ACTIVITIES (07-9083-1' The following lists current activities related to inspection and maintenance activities.
| |
| Inspection PM 05436 with a frequency of 624 weeks and a scope of OBTAIN THE SERVICES OF A CONSULTANT/LABORATORY TO (1) OBTAIN SAMPLES AND ANALYSIS OF EXTERIOR CONCRETE COVERING OF ATMOSPHERICALLY EXPOSED CIRCULATING WATER PIPE AND (2) OBTAIN SAMPLES AND ANALYSIS OF EXTERIOR CONCRETE COVERING WITHIN THE SPLASH ZONE OF THE 4-138" DISCHARGE PIPE. (RECOMMEND STRUCTURAL INTEGRITY, ORIGINAL LCM CONSULTANT AND TOOK INITIAL SAMPLE AND ANALYSIS, PM IS A RECOMMENDATION FROM SI).ALSO A WORK PACKAGE MAYBE REQUIRED TO PROVIDE ACCESS TO LOCATION AND REPAIR THE DISTURBED AREA (THIS WILL DEPEND ON DEPTH OF CONCRETE REMOVED).
| |
| * Inspection PM's 05648 and 05649 for theID of the Unit I and 2 CW Pipe respectively with a frequency of C3 (every third cycle or 4.5 years) has a scope of DRAIN PIPING AND PROVIDE ACCESS TO PERFORM MATERIAL CONDITION INSPECTION.
| |
| REPAIR ANY NOTED DEFICIENCIES THAT CANNOT MAKE A REFUELING CYCLE, OTHERWISE DOCUMENT FINDINGS AND CORRECT IN NEXT OUTAGE. This is an ID inspection only.o In addition to this scheduled inspection of the 96" above ground pipe and the buried and above ground 138" an inspection of the ID of the 96" pipe is conducted every cycle (every 18 months)also.* The OD of the above ground 30" OC and 96" and 138" CW pipe is periodically inspected.
| |
| WORK PRACICrES (07-9083-7)
| |
| The following work practices are observed during various evolutions." Liquid Radwaste is discharged through a portion of the Open Loop System to the Circulating Water System. Both the CW and OC Operating Procedures require that the systems remaining in service for a prescribed time after completion of the discharge of Liquid Radwaste to prevent any potential contamination in the CW and OC systems.* Precautions are taken during the drain down of the CW and OC Systems.o All joints on the temporary pipe are wrapped.o Berms are placed around the storm drains in the vicinity of the drain-down pumps and temporary pipe.o The temporary pipe between the supplemental cooling towers and the selected chillers is sloped to toward the Turbine Building.* Warning signs arc posted in certain sections of the OC System requiring HP personnel when a pipe connection is breached.

| SYSTEMS QUESTIONAIRE GROUNDWATER PROTECTION INITIATIVE System: RCB Tendon Gallery Sump Pumps (DR)Name: Matthew Matt Date: 07/07/08 System
| |
| | |
| == Description:==
| |
| (Provide a brief description of the purpose of the system)The RCB Tendon Gallery Sump Pumps (also known as the Fire Protection Drainage System Sump Pumps) are designed to remove water from the RCB Tendon Gallery Sumps and discharge it to the Yard Storm Drainage System. They are considered to be part of the Non-Radioactive Drains system (DR). The water in the sumps has four possible sources: fire protection water from the EAB cable spreading rooms and chases in the event of a fire and fire protection actuation, from the floor drains located on the -36'9" level of the tendon gallery, any seepage or condensation into the tendon gallery from outside sources (rain, humidity, etc.) and the drainage of groundwater seepage from FHB Room 1 A (described in DCP 01-4145-1 and 2). None of the first three sources are generally radioactive and none would be expected to be radioactive in non-accident conditions (that is, there could be some release of radionuclides to the EAB during an accident that might be washed to the sump in the event of a fire protection actuation but this is not relevant for the purposes of groundwater protection).
| |
| The fourth source is not radioactive under normal conditions but if there were through-wall leakage from the 16" Safety Injection line in the room, it would be possible for contaminated water to drain to the sumps. This is highly unlikely and would be detected through mechanisms such as system pressure tests, local leak rate tests, operator rounds, etc.(Ref. SPEC-DESIGN 9QO60MS 1035)In summary, this is not a credible avenue for groundwater contamination by radionuclides.
| |
| Construction Materials:
| |
| The pumps have a stainless-steel impeller, aluminum housing and zinc-plated carbon steel strainer.Location: (Above or below ground, located within structures, etc...)The RCB Tendon Gallery Sump Pumps are located below grade on the -39'9" level between the RCB and EAB. The discharge piping is routed up through the tendon gallery access area in the EAB and out to the Yard Storm Drainage System.Potential for leak: (Identify Wfsmall leaks would be detected and repaired, or if leaks would likely be a catastrophic failure)Any leakage from the pumps would be directed to the sump. Leakage from this system does not represent a credible source for groundwater contamination.
| |
| Historic Repairs/Maintenance Activities:
| |
| Not researched given the lack of credibility of these pumps as a source of groundwater contamination.

| SYSTEMS QUESTIONAIRE GROUNDWATER PROTECTION INITIATIVE System: Liquid Waste (WL)Name: Matthew Hiatt Date: 07/07/08 System
| |
| | |
| == Description:==
| |
| (Provide a brief description of the purpose of the system)"The function of the liquid waste processing system (LWPS) is to collect, segregate, process, recycle and discharge various liquid wastes during plant operating power, refueling and maintenance operations". (Ref. DESIGN-SDM 5R309ND1014, Rev. 4, page 1)The liquid waste system is designed to process contaminated fluids for eventual discharge into the environment.
| |
| The system collects radioactive water from various sources within the plant including the equipment drains, floor drains, laundry and regenerated wastes. The liquids are processed through a collection of demineralizers, filters, ALPS and holding tanks (to allow for decay of the various nuclides present in the water) to reduce the concentration of radioactive nuclides in the water below the limits for release into the environment.
| |
| Construction Materials:
| |
| The vast majority of the piping in the WL system is made according to piping specification WG. This specifies that the pipe is quality class 7 and be made of Schedule 40S stainless steel (A312 316 or 316L). The one section of buried piping in the WL system has a 6" guard pipe made to specification XC around 4" process pipe made to specification WG. The guard pipe is quality class 7 seamless carbon steel (A106 Grade B). There are also limited portions of the system made to the WD, WR, WN, RC and RB specifications.
| |
| With a few exceptions (i.e.nitrogen supplies to the RCDT, LASRST, etc.), most of the piping made to these specifications is no longer used because the equipment it supplies has been abandoned in place or is not used (i.e. waste evaporator package, auxiliary steam supply, etc.). (Ref. SPEC-DESIGN 5L0 1 9PS0004, Rev. 21)The Yard Area Waste Monitor Tanks are constructed of stainless steel (A240 316L) with welded seams and welded nozzle connections. (Ref VTI-DRAW 4442--00029UU)
| |
| Location: (Above or below ground, located within struclures, etc...)"The majority of the LWPS are located in the Mechanical Auxiliary Building (MAB) with some equipment in the Reactor Containment, the Fuel Handling Building and the Yard Area".(Ref DESIGN-SDM 5R309ND1014, Rev. 4, page 2)The majority of the WL system piping is located within the MAB with smaller sections in the FHB, RCB and Yard Area. The portions of the WL system that are in the Yard Area are associated with Waste Monitor Tanks (WMT) D, E and F on the south side of the MAB.There is one section of buried pipe (4"WL1596-WG7 inside 6"'WL1596-XC7) that runs from the Yard Area down to a penetration in the MAB at 22' 6". Otherwise, all of the Yard Area WL piping is above-ground.
| |
| Potential for leak: (Identify if small leaks would be detected and repaired, or if leaks would likely be a catastrophic failure)Given the low operating pressures/flow-rates in the WL system, the materials used for the process piping and the process fluid (very dilute boric acid), the locations with the highest potential for leakage are mechanical joints such as flanges and valve packing. Because most of the WL process piping is located indoors, the only area where leaks would present a credible groundwater contamination issue is on the piping around the WMTs in the Yard Area and the WMTs themselves.
| |
| Given the materials of construction used for these components and the methods of construction (almost every joint is welded and the one section of buried pipe has a guard pipe surrounding it), leakage is unlikely.In the event a leak did occur in the Yard Area, it would be detected in a timely fashion as this piping is monitored daily by plant operators during rounds. Regular walk-downs of the Yard Area piping by the System Engineer for Freeze Protection and for system monitoring would also ensure that leakage is observed and corrected in a timely fashion. Furthermore, plant operators log the WMT levels daily as part of their rounds and would observe a decline in level if significant leakage were to occur downstream of the WMTs. There is also a 26 week PM to inspect and clean the berms around the tanks. Performance of this PM helps to ensure that leakage is identified in a timely manner.The consequences of leakage from the outdoor WMTs are also not as significant as leakage from other areas of the WL system since this is the last step before the water is discharged to the reservoir.
| |
| The concentration of radionuclides in the water in the outdoor WMTs is near or below the limits for radioactive effluent and thus the amount of contamination that can be spread from a leak is limited. Leakage from the WMT area should flow into the sump area and be pumped back into the WMT by the WMT Sump Emptying Pump which will further minimize groundwater contamination.
| |
| Historic Repairs/Maintenance Activities:
| |
| There have been a number of CRs and work orders written to track leakage in the WL system but there are currently no leaks being monitored in the radwaste yard area. All of the identified leaks on the WI system are located inside the MAB or RCB. The maintenance history on the outdoor WMTs does not record any leakage from the tanks.The maintenance history on the outdoor WL components showed a total of 6 work orders over 20 years of operation to correct external leaks. Most of these leaks were on the seals for the various WMT pumps or the WMT Sump Emptying Pump. Given the relative infrequency of these work orders when compared to other pumps in the plant, no additional PMs (there are existing Inspect and Lube PMs on a 208 week frequency for all of these pumps) will be generated and the frequency will not be changed-Work Practices (Include frequency of inspections and proposed modifications/upgrades):
| |
| The WMTs and their associated piping are monitored daily during operator rounds. On a less frequent basis, they are also monitored by the WL System Engineer as part of normal system monitoring and Freeze Protection walk-downs.
| |
| There is also a 26 week PM (06000652 for Unit I and 06000658 for Unit 2) to "Inspect and clean area inside berms surrounding the waste monitoring tanks and pumps". Performance of this PM provides both an opportunity to identify leakage and an improvement in the ability of the operator or engineer to spot leakage during their regular walk-downs (i.e. no loose debris to hide boric acid deposits).
| |
| If a leak is identified in this area, it would be monitored under the Fluid Leak Management Program (OPGP03-ZA-0133) or the Boric Acid Corrosion Control Program (OPGP03-ZE-0133).

| S ( EVALUATION J J Condition Report 06-1056.Groundwater Tritium within the Protected Area Event
| |
| | |
| == Description:==
| |
| | |
| Nuclear power facilities release tritium to the atmosphere and in liquid effluents.
| |
| The nuclear power industry has identified issues with unmonitored tritium and tritium in local ground water. STP is evaluating tritium at ST? and is tracking associated actions on related Condition Report 06-3826.STP is known to release about 2000 Curies of tritium each year, mostly to the main cooling reservoir.
| |
| The main cooling reservoir is the source of the circulating coolant used to condense secondary steam as part of the electric generation process. Because tritium is released to the reservoir, the tritium concentration in the circulating coolant normally ranges between about 9,000 to 15,000 pCi/kg.The reservoir is above grade so hydrostatic pressure forces some reservoir water into the shallow groundwater aquifer. Hence tritium is routinely measured in groundwater from shallow relief wells that encircle the main cooling reservoir.
| |
| In 1999 samples were collected from the tendon gallery sumps of the Units to determine the concentration in groundwater leaking into these areas of the plant The coancent-ations measured (about 4000 pCi/kg) were consistent with the reservoir concentration at that time. Recently a set measmuments of the groundwater associated with shallow wells within the protected area also identified trace concentrations of tritium. The oncentrations measured (up to about 1000 pCi/kg were much lower than the reservoir water (13,000 pCi/kg) with the highest concentrations closest to the reservoir.
| |
| However, Well #221C located between the two Units had a tritium concentration similar to the reservoir.
| |
| The slightly elevated concentration measured between the two Units may be due to a source other than infiltration of the main cooling reservoir water into the ground water within the protected area. To answer this question, a comprehensive set of samples was obtained from all the wells within the protected area from which samples could be collected.
| |
| In addition samples were collected from all spaces within the two Units into which groundwater was thought to penetrate.
| |
| si:incan: If trititun were entering the groundwater from a source not identified by the ODCM, STP could have an unmonitored effluent release point In that event, the ODCM would require modification and a method to quantify the release would be necessary.
| |
| This analysis did M identify a new release point Apparent Cause The elevated concentration of tritium for Well #221 C (shallow) is most likely due to leakage from piping buried in the vicinity of the well. The Total Dissolved Solids (IDS) pipe from Unit 2 passes about 20-feet west of the well and is known to have leaked in this area in May of 2003. The circulating coolant and open loop coolant lines pass east of Well #221C about 35-feet. All are relatively shallow which would explain the lower tritium concentration in the adjacent but deeper Well #221E.Recommended Actions: 1. Continue monitoring Wells #221C and #221E quarterly to identify any change in the concntratiofi of tritium.
| |
| : 2. Perform chloride and sulfate checks of the Well #221C water for comparison with the TDS and circulating colant concentrations.
| |
| : 3. Anmually sample Wells #220C, #222C, and #273K (north, south, and east respectively) to identify any spread of the tritium in the shallow aquifer.If the triuimn concentration in Well #221C increases above 20,000 pCi/kg or the tritium concentration in any of the surrounding wells indicates spreading of the tritium in the shallow aquifer, additional actions should be considered.
| |
| Additional Information:
| |
| Groundwater in the shallow aquifer was sampled from wells within the protected area as shown in the following figure. Groundwater that seeped into the Units was also sampled although the building environment likely affected the measured tritium concentrations.
| |
| Wells were purged with about 5 gallons of water before collecting samples. The wells had maximum pipe diameters of about 1.25 to 1.75 inches; hence each gallon of water cleared about 31 feet of pipe.Most of the wells were less than about 40 feet deep and sampling at these wells was within about a foot of the bottom. When a well was deeper than the length of sample hose, the sampling was performed at the maximum hose length. Note that all depths are the depth of the well measured from local graft level. Local grade is about 29 feet above sea level in most aras.Four wells were sampled in duplicate.
| |
| At locations with more than one well, both deep and shallow wells were sampled as available.
| |
| Wells designated by the letter "C" were typically the shallowest.
| |
| Wells with an "E" or other designator were deeper, some more than the sample hose length (up to 62 feet). The samples were collected from December 2005 through February 2006.The samples collected within the Units involved scooping a gallon of water from standing water in each arm sampled. The sampling method assumed that tritium was well mixed in the water since in all cas the water had been standing for extended periods of time, sometimes exceeding a year.The following figure contains the well locations relative to the excavation performed for the foundations of each unit Wells surrounded by green boxes were found to have trace amounts of tritiwn from less tan detectable
| |
| (<300 pCi/kg) up to about 500 pCi/kg. The wells surrounded by orange boxes contain tritium concentraions up to about 1500 pCi/kg and appear more strongly influenced by the reservoir.

The tritium concentration in the reservoir typically runs about 10,000 pCi/kg but has recently (2005) increased slightly to about 13,000 pCi/kg. The only samples that approached or exceeded the reservoir concentration are indicated in red. Of the well samples, only the shallow aquifer sample from Well #221C indicated an elevated tritium concentration and it was similar to that of the reservoir.
| |
| Generally the deeper well at a location where tritium was measured had a higher concentration than the shallower well. Of the 14 locations sampled and found to contain tritium at some depth, only Wells#221 C and #222C had a higher concentration in the shallower well than the deeper. These two wells arn both located between the two units.Plant liquid effluents are discharged into the reservoir the tritium activity is reported; and the concentration in the reservoir is monitored monthly. The circulating coolant and open loop coolant water is from the main cooling reservoir which is known to contain tritium. The circulating coolant and open loop coolant piping run parallel to one another and within about 20 feet of the surface. Both carry reservoir water near Well #221 (about 35 feet away) as shown in the figure on the following page.Although the water pressure is low it is possible that one of these pipes leaks into the backfill material between the two units. This could explain the elevated result for Well #221 C and the fact that it is very similar to the reservoir's tritium concentration.
| |
| The Unit 2 Total Dissolved Solids (TDS) line also rnms within about 20-feet of Well #221C and is also shallow. This line leaked and was repaired in May 2003 (Condition Report 03-7595, WO #430966).The TDS line carries Condensate Polisher Regeneration Waste water from the secondary to the neutralizaion basin prior to discharge into the reservoir.
| |
| TDS waste water is known to contain small amoumts of tritium. This tritium is included in the liquid effluent to the reservoir and subsequenfly a fraction is known to enter the shallow water. Although the tritiun concentration (up to 26,000 pCi/kg)in the water carried in this line is may be higher than measured in Well #221C, dilution in th ground water could explain the 13,000 pCi/kg measured.All of the groundwater infiltration samples from within the Units are a significant fracion (> 1W.) of the reservoir water concemtration.
| |
| However, tritium within the plant may have contributed to these elevated values. The tritium results for samples 40254 and 40255 are elevated above the reservoir concentrations and cannot be fMlly attributed to reservoir water leakage into the groundwater near the Units. These two samples were collected from rooms (FEB Rm 007) inside the radiologically controlled areas of Units I and 2 respectively.
| |
| These spaces may be influenced by tritium contained in plant systeis; however, in-leakage of groundwater is also known to occur. Although the tritium concentrations in these areas are elevated above the values found elsewhere, it is unlikely that tritium in the groundwater caused these elevated levels.The air in the fuel handling buildings contains moisture largely originating from the spent fuel pooL Water condensed from the fuel handling building air contains tritiun at a concentration of about 2.OE+06 pCi/kg (samples #40362 and #40368). Monthly, the building ventilation is isolated for routine testing and plant personnel report that at those times (about 6-hours each month) the concrete "sweats" when moisture in the air condense A little mixing of this water with the groundwater infiltrating FEB Rm 007 could account for the elevated tritium concentration of these samples. Note that water removed from this area (an infrequent activity) it is discharged into the radioactive waste processing system and is monitored prior to release to the reservoin Condition Report 06-3508 addresses the issue of tritium identified in groundwater that has collected within the Units.
| |
| The chemical characteristics of selected samples were also measured in hope of identifying the probable source of the water. A sample of circulating coolant was collected by Chemistry so that its chemical characteristics could be compared to those of other samples as shown in the following table.Chemical Characteristics of Water Samples Conductivity Chloride Sulfate Nitrate Silica Boron Tritium Sample Point Date/ ime (uS) (ppm) (ppm) (ppm) (ppm) (ppm) (pci/kg)Ciro Water 1/24/2006 13:57 3580 911 175 55 16.4 --13,000 Well 221C 12/1/2006 11:15 25100 38 1615 3965 21.5 -- 13,500 Well 244C 12/1/2006 14:25 29700 1086 222 4394 23.5 <- LLD U-1 FAB 10' sumnp 1/9/2006 13"30 24200 7.5 9.3 3470 14.5 -2030 U-2 64deg.Buttress 119/2006 13:00 21800 10.9 6.8 3182 7.3 -13,800 Unit 122?

The following table shows that none of the water samples suspected to be kfuenced by circulating coolant or reservoir water had conductivity mil to the-circulating coolant The conductivity values for the tritium containing test samples span a relatively small range of conductivity (21,800 to 30,000) and are 6 to S times higher than the circulating coolant value of 3580. Since they are much closer to the unaffected groundwater conductivity of Well 244C, these measurements do not support large scale circulating coolant or reservoir water displacement of the groundwater as the source of the tritium in Well #221 C. The anion analysis did not suggest that the circulating coolant was the source of tritium either since the anion concentrations were not similar. Although these data do not appear to support leakage of circulating coolant as the source of the tritium in Well #221 C they do not preclude that possibility.
| |
| Note that although the chloride and sulfate concentrations at Well #221 C do not match the circulating coolant, they do parallel the TSD line water values where we typically find low chlorides and elevated sulfats.Samples of suspected groundwater from the fuel handling buildings, -29' FHB Rm 007, of each Unit wer also analyzed.
| |
| These two samples had much highcr tritium n than the c coolant, but they were collected within the radiologically controlled area of each fuel handling building and were likely influenced by airborne or other sources of tritium in the buildings.
| |
| Note that neither of these two samples contained significant boron -on-entratzons.
| |
| The spent fuel pod boron concentration in Unit 2 is about 3000 ppm and its tritium concenration is about 2.8E+07 pCi/kg. Ifthe tritium were due to spent fuel pool water or simila leakage, the boron concentration in FHB Rm 007 of Unit 2 should have been about S ppm. Hence, the tritium in this area is likely due to sources within the building but not from spent fuel pool water leakage. The conductivity of the water suggests that it is likely groundwater infiltration rather than the de-mineralized water used in plant systems.

| Monitoring Well Documentation Groundwater Protection Initiative South Texas Project Electric Generating Station Dear Ms. Dannhardt This letter report provides the drilling and well construction details as well as the final 'as built' drawings to supplement the Conceptual Site Model completed in support of the NEI 07-07 Groundwater Protection Initiative-In accordance with the recommendations in the Conceptual Site Model Report (MACTEC, 2008), five groundwater monitoring wells were installed at the South Texas Project Electric Generating Station (STPEGS) located near Wadsworth, Texas. The wells were installed to supplement the existing groundwater monitoring network and to specifically provide data along the easrand downgradient side of Unit.2 as well as west of the Main Cooling Reservoir.
| |
| Monitoring well locations are shown on Figure I.Wells were installed and developed in accordance with the specifications provided in Attachment A. Boring logs and well installation details are provided in Attachment B.In accordance with state regulations, well permits were submitted by Lewis Environmental Drilling, a Texas-licensed driller, to the Texas Department of Licensing and Regulation on December 11, 2008. Copies of these forms are provided in Attachment C.It should also be noted that the wells were proposed to be installed to intersect the watertable.
| |
| However during the drilling the saturated soils were encountered at approximately 16 to 20 feet below ground surface. The shallow wells (MW-801L, 802L;803L and 805L) were then installed to span the interval where saturated soils were first encountered.
| |
| As is common in the area, the water table is located in a semi confined aquifer and therefore the depth to water following installation stabilized at approximately 8 to 12 feet bgs, several feet above where the saturated soils were first encountered.
| |
| No modifications need to be made to the Conceptual Site Model, nor is this a deviation from the work plan. This should just be documented should questions be asked during an assessment or follow up to the NET 07-07 initiative.

| |
| ATTACHMENT A DRILLING SPECIFICATIONS STPEGS UNITS I & 2 DRILLING Drilling activities shall be completed by a Texas-Licensed driller. Water shall be provided by STP.All discharge water shall be controlled to prevent excessive erosion, pollution, contamination, or other damage. The preferred drilling method shall be by hollow stem augers, but rotary drilling, or a casing advancement drilling methods are also acceptable.
| |
| For rotary drilling, potable water is the preferred drilling fluid or a biodegradable drilling fluid additive, as required.Soil samples shall be collected generally at 5 foot intervals however additional samples may be requested by the CONTRACTOR based on soil stratification and professional judgment.
| |
| Soil samples shall be collected using a 2-inch OD split-barrel sampler. The holes shall be re-cleaned to the bottom if the split-barrel sampler does not rest on the bottom prior to sampling.
| |
| The sampler shall be driven a minimum of 18 inches or to refusal, which is defined as a penetration of 6 inches or less per 50 blows. The samples obtained shall be logged and the soils returned to the cuttings pile to be managed as investigation derived waste (IDW). Standard Penetration Test hammer system shall use either NW or AW size rods. Other systems may be used, with approval from the CONTRACTOR-Abandoned and Grouting of Boreholes If the termination criterion is not met, and the borehole cannot be completed with well installation, the borehole shall be filled with cemenlberntonite grout to the ground surface. The grout shall be prepared in the following approximate proportions:
| |
| 8 gallons of water and 2.5 pounds of powdered bentonite per 94-pound sack of Portland cement The grout shall be placed using the tremie method to the bottom of the borehole and slowly raising it while pumping the grout into the hole.The tremie end shall be continuously submerged in the grout until the grout reaches the ground surface. Should loss or shrinkage of the grout occur after the hole is filled, the hole shall be refilled until it remains full.Boreholes abandoned before reaching the specific final depth because of mechanical failure of the drilling equipment, negligence or operator error on the part of the SUBCONTRACTOR, or other such preventable causes, may be rejected by the CONTRACTOR.
| |
| Any hole rejected by the -CONTRACTOR shall be supplemented by another hole drilled adjacent to the first.WELL INSTALLATION Groundwater monitoring wells shall be installed in general accordance with ASTM D 5092, and in compliance with any local or state regulations.
| |
| The CONTRACTOR shall obtain all local and state permits required to drill and install wells. The final design (depth of well screen placement) for each well will be based on the field conditions encountered during drilling and will be determined by the CONTRACTOR or on-Site representative.
| |
| Four shallow (upper) wells are anticipated to be installed to depths of 40 feet or less. The one deeper (lower) well proposed for this field event is anticipated to be installed at a depth no greater than 70 feet bgs.Borings drilled for monitoring wells shall be drilled a minimal of 8 inches in diameter to a depth of approximately 2 to 3 feet below the bottom of the target well depth. Any water source or additive must be approved by the CONTRACTOR prior to use.I PAPfrjec%\STP

The casing shall be clean, straight and free of obstructions.
| |
| If requested by the CONTRATOR, well materials will be pressure washed with potable water prior to well installation.
| |
| Well screens shall be comprised of 2-inch Schedule 40 PVC with 0.020 inch manufactured or machine cut slots. Screens shall be 10 feet in length. The bottom of the screen shall be fitted with a blank casing (or silt trap) approximately I foot in length. The bottom of this casing shall be capped.Filter pack material shall be clean, well-graded sand. The selected filter pack shall be 10/20 sand as recommended in ASTM D 5092 or equivalent, as approved by the CONTRACTOR.
| |
| The filter pack shall extend a minimum of 2 feet above the top of the screen or as directed by the CONTRACTOR.
| |
| A bentonite seal will then be installed immediately above the top of the sand pack. The bentonite chips, pellets, or a slurry may be used to install the seal. The seal must be a minimum of 3 feet thick. The remaining annular space will be backfilled with cement/bentonite grout to approximately 1 foot below ground surface (bgs).Well Construction The well will be lowered into the hole with oversight from the CONTRACTOR-The sand pack will be installed into the annular space between the casing and the PVC, prior to pulling back the casing. The sand pack will be installed in such a way that at no time will the PVC well screen be exposed to the surrounding native soils. As noted above, the sand pack shall be installed to a minimum of 2 feet above the top of the screen.After the sand pack is installed a bentonite seal (using pellets, chips or a slurry) shall be installed with a minimum thickness of 3 feet. If a slurry is used, then the seal shall be installed via tremie hose. Pellets or chips may be installed from the ground surface.Following placement of the seal, the remainder of the annular space between the riser casing and the borehole will be backfilled with a cement/bentonite grout. The grout shall be placed via tremie hose and pumped into the annular space to I foot bgs. If the grout settles, additional grout will be used to top off and fill the annular space.After the grout has settled, a protective, lockable steel casing shall be installed over the top of the riser. Protective casings shall consist of stick ups or flush mounted road boxes. The CONTRACTOR in conjunction with STP will determine what type of well completion will be selected.
| |
| The protective casings will not extend more than 6 inches above the top of the PVC riser.If flush mounted protective casings are used, then a compression cap shall also be installed on the PVC riser to firther protect the well To complete installation of the protective casing, a concrete seal at least 2 feet square and 1 foot thick shall be installed around the protective casing. The surface of the seal shall extend partially above the ground surface and slope away from the well. The concrete surface seal shall consist of Portland cement (ASTM C 150), fine and coarse aggregate, and water, proportioned and mixed as to produce a plastic workable mix. The aggregate material used for the concrete mixture shall conform to ASTM C 33.2-EPU GW Initiativc4_0_Dchvcrblcs\4.I_Rcpot\WeNl Doc--umeation fur CSM\Atzochbmen AttacbeMent A -drilling specs -rcvise&doc ATTACRMENT A DRILLING SPECIFICATIONS STPEGS UNITS 1 & 2 If stickup completions are to be installed, two seep holes shall be drilled in the steel well cover just above the top of the concrete surface to allow for water to drain- The stickups shall then be painted with a rust preventative having a bright reflective color. For flush mounted completions two seep holes shall be drilled below the concrete seal to allow for drainage of standing water, should it collect over time. Alternatively a layer of sand may be installed at the base of the roadbox to allow for drainage.Well Development Each well shall be developed by bailing, surging, airlifting or pumping to remove sediment from the well and filter pack. Development will continue along the length of the well screen until the well produces clear water, or development has occurred for 2 hours. For clay and silty formations, 5 well volumes may be removed over time in an attempt to clean out the sediment (it should be noted that for this circumstance, the water will likely remain turbid after development).
| |
| The CONTRACTOR shall approve the method and duration of development.
| |
| Each well shall be developed following a minimum of 24 hours after installation.
| |
| Monitoring wells may be sampled for radionuclides after a seven day equilibration period following the development.
| |
| DECONTAMINATION All materials including the drill rig may be washed using a steam cleaner or pressure washer, using potable or other approved water source. The rig and drilling equipment (augers/casing) will be decontaminated upon mobilization, and then again in between boring locations.
| |
| Decontamination fluids will be allowed to be discharged to the ground, but the SUBCONTRACTOR shall take care not to cause erosion, ponding, or to release the fluids to the storm water system.GROUNDWATER TRITIUM SCREENING Groundwater associated with the proposed wells may contain tritium at concentrations above background, however, based on generator knowledge tritium concentration will be well below the Maximum Contaminant Levels (MCLs) issued by the Environmental Protection Agency (EPA).The CONTRACTOR will work at the direction of STP's Health Physics personnel who will determine if screening samples are required.
| |
| STP will provide "Right to Know" training prior to drilling.
| |
| However, based on the existing data, no additional precautions will be taken during drilling.SURVEYING SERVICES Qualified land surveyors shall perform the survey in compliance with requirements of the State of Texas. Ground surface elevations shall be based on the 1929 National Geodetic Vertical Datum (NGVD) of the 1988 North American Vertical Datum (NAVD). The horizontal survey to locate completed wells shall meet third order accuracy (1:5,000) and the vertical accuracy shall be to the nearest 0.1 ft.3 PAPrpjets\STP
