| |
| Provided below is a brief explanation of the table.
| |
| A. Liquid (Individual)
| |
| Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-1 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-1 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-1 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-1 liquid discharge.
| |
| For 2006 the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 1.35E-2 mrem to an adult (line 1). The maximum organ dose was 1.51 E-2 mrem to the liver of an adult (line 2).
| |
| B. Gaseous (Individual)
| |
| There were six major'pathways considered in the dose calculations for TMI-1 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.
| |
| Lines 3 and 4 present the maximum plume exposure at or beyond the site boundary. The notation of "air dose" is interpreted to mean that these doses are not to an individual, but is considered to be the maximum doses that
| |

| TMI-2 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2006 TMI-2 releases of gaseous and liquid effluents.
| |
| Provided below is a brief explanation of the table.
| |
| A. Liquid (Individual)
| |
| Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-2 were the consumption of drinking water and fish and standing on the shoreline influenced by TMI-2 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-2 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-2 liquid discharge.
| |
| For 2006 the calculated maximum whole body (or total body) dose from TMI-2 liquid effluents was 4.39E-4 mrem to an adult (line 1). The maximum organ dose was 6.90E-4 mrem to the liver of a teen (line 2).
| |
| B. Gaseous (Individual)
| |
| There were six major pathways considered in the dose calculations for TMI-2 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.
| |
| Since there were no noble gases released from TMI-2 during 2006, the gamma and beta air doses (lines 3 and 4, respectively) were zero.
| |
| The maximum organ dose due to the release of particulates and tritium from TMI-2 in 2006 was 3.97E-5 mrem to the liver, total body, thyroid, kidney, lung and GI tract of a child residing 2000 meters from the site in the SE sector (line 5).

| Attachment 8 2006 Annual Radioactive Effluent Releases Report for TMI 5928-07-20096 Assessment of Radiation Doses from Liquid and Gaseous Effluents Releases to Members of the Public within the TMI Site Boundaries during 2006 The Offsite Dose Calculation Manual requires an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of the public due to their activities inside the site boundary during the reporting period. The estimated dose to a member of the public at or within the TMI Site Boundary was 0.65 mrem for 2006.
| |
| The following are the assumptions made in this assessment:
| |
| Access to the TMI Owner Controlled Area is limited to only those persons who have business related activities that support the operation of the facility. Therefore, based on the definition of a 'member of the public' in NUREG-1 301, there is no credible scenario for this individual to receive non-occupational dose inside the TMI Owner Controlled Area. The scenario selected will be recreational use of the Susquehanna River and shoreline next to the Owner Controlled Area fence. Based on the two definitions of Site Boundary in the ODCM, this scenario is AT the Site Boundary for liquid releases but INSIDE the Site Boundary for gaseous releases.
| |
| A member of the public stays next to the owner controlled area for 67 hours. The 67 hours is based upon Reg. Guide 1.109 shoreline recreation period given in Table E-5.
| |
| This is a table of recommended values to be used for the maximum exposed individual in lieu of site-specific data. Three Mile Island is co-located with other islands in the Lake Frederick area of the Susquehanna River. This area is used recreationally for boating and fishing over the summer months. The application of the 67 hours of recreational use from Reg. Guide 1.109 is appropriate.
| |
| The dose from liquid effluents was included in this scenario. The highest activity contained in releases from TMI is from batch releases from the Waste Evaporator Condensate Storage Tanks. The maximum time period for a single release was 22 hours. Since the time of a single release is less than the 67 hours of recreational use of the river, the highest quarterly cumulative dose from liquid effluents will be used in this calculation. The highest quarterly cumulative dose was 3.56E-2 mrem, total body. This cumulative dose included both batch and continuous liquid releases. Assuming that the total dose from a quarter was received in the 67 hours is conservative.
| |
| The highest dose from a single airborne release is characterized by release G200605549. This release contained the highest concentration of tritium of any gaseous release. In 2006, tritium released in gaseous effluents comprised 98 percent of the total curies released to the environment. No other releases would yield a higher dose than the release with the highest tritium concentration. This release occurred over 503 hours. The entire dose from this release will be applied to the 67 hour recreational use period. The application of the total dose from this release to 67 hours is
| |
| | |
| 4 "'L conservative. The total dose from release G200605549 was 8.24E-4 mrem to the critical receptor.
| |
| The highest fenceline TLD result (assumed to be equal to dose) will be added to the dose from the highest liquid and gaseous releases to yield the hypothetical maximum dose to a member of the public within the site boundaries.
| |
| The highest fenceline TLD result for 2006 was from Station Li-1 and was 6.6 mrem per standard month. The net TLD dose, obtained by subtracting the results from a control station TLD from the indicator results, was not used. This again is conservative.
| |
| Calculations:
| |
| 6.6 mrem/std mo.
| |
| * 1/30.44 d/std mo.
| |
| * 1/24 hr/day
| |
| * 67 hr = 0.61 mrem The dose from gas release G200605549 was 0.000823 mrem.
| |
| The quarterly cumulative dose from liquid effluents was 0.0356 mrem.
| |
| Total Dose Calculation 0.61 mrem + 0.000823 mrem + 0.0356 = 0.65 mrem
| |

| |
| Attachment 9 2006 Annual Radioactive Effluent Releases Report for TMI 5928-07-20096 Assessment of Radiation Dose to Most Likely Exposed Real Individual per 40 CFR 190 Dose calculations were performed to demonstrate compliance with 40 CFR 190 (ODCM Part IV Section 2.10). Gaseous and liquid effluents released from TMI-1 and TMI-2 in 2006 resulted in maximum individual doses (regardless of age group) of 0.0211 mrem to the thyroid and 0.0264 mrem to any other organ including the whole (total) body. The direct radiation component was determined using the highest quarterly fence-line exposure rate as measured by an environmental TLD, and subtracting from it, the lowest quarterly environmental TLD exposure rate.
| |
| Based on the maximum exposure rate of 6.6 mR/standard month, a person residing at the fence-line for 67 hours (shoreline exposure from Reg. Guide 1.109) received an exposure of 0.61 mR. Based on the lowest exposure rate of 4.1 mR/standard month and converting it by the same method yielded a background exposure of 0.38 mR.
| |
| Therefore, the net exposure from direct radiation from TMINS was 0.23 mR. Combining the direct radiation exposure (assumed to be equal to dose) with the maximum organ doses from liquid and gaseous releases, the maximum potential (total) doses were 0.25 mrem to the thyroid and 0.26 mrem to any other organ. Both doses were well below the limits specified in 40 CFR 190.

| .1 tý I a Attachment 10 2006 Annual Radioactive Effluent Releases Report for TMI 5928-07-20096 Deviations from the ODCM Sampling and Analysis Regime during 2006 There were two deviations from the ODCM sampling program in 2006.
| |
| The Unit 1 Turbine Building Sump Compositor was found empty on October 23, 2006. The compositor was repaired and returned to service immediately. This is a flow proportional composite sampler for continuous releases from the Turbine Building Sump to the Industrial Waste Treatment System. This is a requirement of the ODCM, Part 1, Table 3.2-1 -A.2. Radioactivity concentrations for this sample location are very consistent. Sample results from the week after were used with the volume of water released from the Industrial Waste Treatment System to calculate release doses for the time period the compositor was Out of Service.
| |
| On December 29, 2006, the ESF ventilation system was run for a surveillance without the effluent radiation monitor RM-A-14 and its associated sampling panel in service. The system was shutdown immediately upon recognizing this fact. A release permit was created to calculate the dose for the approximately 4 hours the system ran. This system is emergency ventilation for the fuel handling building and the normal radiation monitor, RM-A-4, for this building saw no change in reading over this time frame. The only isotope occasionally seen .when this. system runs is tritium. The normal weekly grab sample tritium for the spent fuel pool area was used for the dose calculation since no tritium sample was obtained via RM-A-14.

| Assessment of Radiation Doses Due to Radioactive Liquid and Gaseous Effluents Released from TMI during 2005 TMI-1 The attached table presents the maximum hypothetical doses to an individual and the general population resulting from 2005 TMI-1 releases of gaseous and liquid effluents.
| |
| Provided below is a brief explanation of the table.
| |
| A. Liquid (Individual)
| |
| Calculations were performed on the four age groups and seven organs recommended in Regulatory Guide 1.109. The pathways considered for TMI-1 were the consumption of drinking water and-fish and standing on the shoreline influenced by TMI-1 effluents. The latter two pathways are considered to be the primary recreational activities associated with the Susquehanna River in the vicinity of TMI. The "critical receptor" or Receptor 1 was that individual who 1) consumed Susquehanna River water from the nearest downstream drinking water supplier (Wrightsville Water Supply), 2) consumed fish residing in the vicinity of the TMI-1 liquid discharge outfall and 3) occupied an area of shoreline influenced by the TMI-1 liquid discharge.
| |
| For 2005, the calculated maximum whole body (or total body) dose from TMI-1 liquid effluents was 4.35E-2 mrem to an adult (line 1). The maximum organ dose was 5.76E-2 mrem to the liver of an adult (line 2).
| |
| B. Gaseous (Individual)
| |
| There were six major pathways considered in the dose calculations for TMI-1 gaseous effluents. These were: (1) plume exposure (2) inhalation, consumption of; (3) cow milk, (4) vegetables and fruits, (5) meat, and (6) standing on contaminated ground. Real-time meteorology was used in all dose calculations for gaseous effluents.
| |
| Lines 3 and 4 present the maximum plume exposure at or beyond the site boundary. The notation of "air dose" is interpreted to mean that these doses are not to an individual, but is considered to be the maximum doses that would have occurred at or beyond the site boundary. The table presents the distance in meters to the location in the affected sector (compass point) where the theoretical maximum plume exposures occurred. The calculated maximum plume exposures were 9.93E-5 mrad and 1.38E-4 mrad for gamma and beta, respectively.
| |
| | |
| The maximum organ dose due to the release of iodines, particulates and tritium from TMI-1 in 2005 was 1.85E-2 mrem to the liver, total body, thyroid, kidney, lung and GI-LLI of an child residing 2000 meters from the site in the SE sector (line 5). This dose again reflects the maximum exposed organs for the appropriate age group.
| |
| For 2005, TMI-1 liquid and gaseous effluents resulted in maximum hypothetical doses that were a small fraction of the quarterly and yearly ODCM dose limits.

These costs may be hard to quantify, but a realistic approximation is needed to justify spending company resources. For example, if the incident did or could shut the plant down for I day, the lost production and power replacement cost of approximately $1M per day plus repair costs, overtime for crews, and other costs would need-to be considered as the cost of the performance deficiency. If the training is regulatory-driven, consider what the costs would be if the training was not done. For example, there might be regulatory fines, plant shutdowns, stop work actions, union walkouts, public relations problems to correct.

| Offsite Dose Calculation Manual NOTE: For 50.59 Evaluations, information on this form will provide the basis for preparing the biennial summary report submitted to the NRC in accordance with the requirements of 10 CFR 50.59(d)(2).
| |
| Description of Activity:
| |
| (Provide a brief, concise description of what the proposed activity involves.)
| |
| The ODCM is being updated to reflect revisions to the requirements for operability of the offgas ventilation radiation monitors.
| |
| Based on the NRC letter to Chris Crane dated 7-19-06 (see attached) confirming that revisions to the condenser vent system low range noble gas monitors operability requirements are now governed by the TS requirements for ODCM revisions, AmerGen does not consider these operability requirements as regulatory commitments in accordance with ASLB Order LBP-84-47. The ODCM is also being changed to clarify a note for operability of RM-A-7 and references to the iodine sampler and radiation monitors for RMA-4 and 6. REMP sample locations were also updated to reflect current locations and to use more accurate distance and azimuth information acquired through GPS readings.
| |
| Reason for Activity:
| |
| (Discuss why the proposed activity is being performed.)
| |
| The revised requirements were requested to bring TMI-1 more in line with current industry guidelines for primary to secondary leakage. The note clarification was identified in IR 44097 during ILT training. The REMP location updates were a result of Global Positioning System (GPS) readings taken during normal sample rounds, corrections from REMP reviews and the addition of an alternate milk sampling farm and food products location in case one of the regular locations is not available. The clarifications for RM-A-4 and RM-A-6 monitors came about as a result of reviews for ECR 06-00061.
| |
| Effect of Activity:
| |
| (Discuss how the activity impacts plant operations, design bases, or safety analyses described in the UFSAR.)
| |
| The revised requirements for the condenser offgas monitoring are consistent with industry guidance provided in EPRI documents for primary to secondary leakage. The note clarification and REMP sample location updates will have no impact on radiological effluent control nor will they change any of the calculations for doses from pathways in the environment.
| |
| Summary of Conclusion for the Activity's 50.59 Review:
| |
| (Provide justification for the conclusion, including sufficient detail to recognize and understand the essential arguments leading to the conclusion. Provide more than a simple statement that a 50.59 Screening, 50.59 Evaluation, or a License Amendment Request, as applicable, is not required.)
| |
| The NRC letter to Chris Crane dated.7-19-06 states that once the operability requirements were relocated to the ODCM they were bounded by ODCM change requirements. Per Technical Specification 6.14, ODCM changes do not require pre-NRC approval, but they do require submittal with the next annual Radiological Effluents Report to the NRC, properjustification and appropriate cross-disciplinary, RTR/SQR and PORC review.

Crane President and Chief Executive Officer AmerGen Energy Company, LLC 4300 Winfield Road Warrenville, IL 60555 SUBJECT THREE MILE ISLAND NUCLEAR STATION, UNIT I - REQUEST TO REVISE CONDENSER VENT SYSTEM LOW RANGE NOBLE GAS MONITOR OPERABILITY REQUIREMENT (TAC NO. MD205B)
| |
| | |
| ==Dear Mr. Crane:==
| |
| | |
| By letter dated May 25, 2006 (Agencywide Documents Access and Management System Accession Number ML061510356), AmerGen Energy Company (AmerGen) submitted a request for Nuclear Regulatory Commission (NRC) approval of a proposed commitment revision regarding the operability requirement for the condenser vent system low range noble gas monitors specified in the Three Mile Island (TMI) Unit 1 offelte dose calculation manual (ODCM).
| |
| AmerGen, in its request, stated that the current ODOM operabIlity requirements applicable to the condenser vent system low range noble gas (condenser vent radiation) monitors fulfill a regulatory commitment in accordance with NRC Atomic Safety and Ucensing Board (ASLB)
| |
| Order LBP-84-47, dated October 31, 1984. Further, AmerGen stated that TMI Unit I Technical Specification (TS) Amendment No. 103, dated December 21, 1984, specifically states that the revised TS included In the amendment conformed with the condition Imposed by the ASLB.
| |
| TS 3.21.2 specified the allowed condenser vent radiation monitors outage time. TMI Unit 1 TS Amendment No. 197, dated October 2, 1995, relocated TS 3.21.2 requirements to the ODCM.
| |
| In accordance with the AmerGen commitment management program, the proposed commitment change modifies the method of compliance specifically defined in the ASLB Order and, therefore, according to AmerGen's program, requires NRC's prior approval.
| |
| The NRC staff has reviewed AmerGen's submittal, its referenced documents, and TMI TS Section 6.14, "Offslte Dose Calculation Manual." Based on Its review, the NRC staff determined that once Amendment No. 197 was Issued, the sections that were relocated from the TS to the ODCM are bounded by the requirements of TS Section 6, "Administrative Contros," which govern technical review and controls of procedures and programs. TS Section 6.5.1.12 requires that AmerGen perform a 10 CFR 50.59 analysis to determine whether or not NRC approval is required. If It is determined that NRC approval Is required, then AmerGen should submit its request in the form of a r1ense amendment request, pursuant to 10 CFR 50.90.

| |
| : 1. Determination Questions (Check correct response)
| |
| : 1. Does the ODCM change maintain the level of radioactive effluent control X YES NO required by 10CFR20.1301?
| |
| Explain: (provide sufficient information including appropriate analyses
| |
| .justifying the ODCM change) 10 CFR 20.1301(a)(1) requires that each licensee conduct operations so that the total effective dose equivalent to individual members of the public from TMI operation does not exceed 100 mrem in one year. The revisions to the condenser offgas monitor operability requirements and changes to clarify notes[ descriptions and update REMP locations will not increase the dose to the public or reduce TMI's ability to control or quantify condenser offgas, Waste Gas Decay Tank or Aux/ Fuel Handling building ventilation releases. The additional compensatory sampling for offgas ventilation releases will enable quantification of noble gases via this release path.
| |
| Continuous particulate and iodine sampling requirements are not impacted by this change. This change also brings TMI more in alignment with the NRC's NUREG-1301, "Offsite Dose Calculation Manual Guidance:
| |
| Standard Radiological Effluent Controls for Pressurized Water Reactors".
| |
| Section 3.3.3.11 for Radioactive Gaseous Effluent monitoring of this guide for Condenser Evacuation system requires 1 minimum operable noble gas activity monitor with grab samples every 12 hours ifinoperable and restore to operable within 30 days otherwise explain in next Radioactive Release Report. Section 3.3.3.11 of NUREG 1301 also states that the shutdown provisions of controls 3.0.3 and 3.0.4 are not applicable.
| |
| The more stringent grab sample and operability requirements are not required explicitly by Radiological Effluent Controls regulations, but are a result of industry guidance from EPRI for primary to secondary leakage.
| |
| TMI chooses to implement this guidance via the ODCM.
| |
| : 2. Does the ODCM change maintain the level of radioactive effluent control X YES NO required by 10CFR20.1302?
| |
| Explain: (provide sufficient information including appropriate analyses justifying the ODCM change) 10 CFR 20.1302 requires licensees to perform appropriate surveys in unrestricted areas and controlled areas to demonstrate compliance with dose limits for individual members of the public. The ability to perform surveys is not impacted by the changes due to the revised requirements or bv the hotel description clarifications and uodates to REMP samole
| |
| | |
| CY-AA-170-3100 Revision 0 Page 3 of 5 ATTACHMENT 2 ODCM Change Determination locations. Effluent concentration limits will not be impacted by these changes. TMI will still control its effluent path to ensure dose to the public is ALARA.
| |
| : 3. Does the ODCM change maintain the level of radioactive effluent control X YES NO required by 40CFRI90?
| |
| Explain: (provide sufficient information including appropriate analyses justifying the ODCM change) 40CFRI90 requires that the annual dose equivalent does not exceed 25 mrem to the whole body, 75 mrem to the thyroid and 25 mrem to any other organ of any member of the public as a result of exposure to planned discharges of radioactive materials to the environment from uranium fuel cycle operations. The changes to the ODCM for the revised requirements or for the note/ description clarifications and REMP location updates will not increase discharges of radioactive materials nor will they negatively impact TMI's ability to control or quantify radioactive releases to the environment.
| |
| : 4. Does the ODCM change maintain the level of radioactive effluent control X YES NO required by 10CFR50.36a?
| |
| Explain: (provide sufficient information including appropriate analyses justifying the ODCM change)
| |
| ICFR 50.36a requires that operating procedures be developed and followed for the control of effluents and that the radioactive waste system be maintained and used. It also specifies that each licensee shall submit a report annually, that specifies the quantity of each of the principal radionuclides released to unrestricted areas in liquid and in gaseous effluents during the previous 12 months. These requirements will keep average annual releases of radioactive material in effluents and their resultant committed effective dose equivalents (CEDE) at small percentages of the dose limits. Operation of the rad waste system is not affected by these changes. The operation of the plant releasing and monitoring the effluents from the condenser offgas system will not be negatively impacted by the revised operability requirements. Two radiation monitors will remain installed and maintained on the offgas effluent. These changes will only affect the actions taken if these monitors are out of service. The revised requirements, the note/ description clarifications and REMP location updates wIl not impact the annual reporting of radiological effluents to the NRC.
| |
| : 5. Does the ODCM change maintain the level of radioactive effluent control X YES _ NO required by Appendix I to 10CFR50?
| |
| | |
| CY-AA-170-3100 Revision 0 Page 4 of 5 ATTACHMENT 2 ODCM Change Determination Explain: (provide sufficient information including appropriate analyses justifying the ODCM change) 10CFR50 Appendix I,, Section II.A establishes the design objectives and limiting conditions for operation to meet ALARA criteria such that the calculated annual total quantity of all radioactive material above background released to unrestricted areas will not result in an estimated annual dose or dose commitment from liquid effluents in excess of 3 mrems to the total body or 10 mrems to any organ. For gaseous effluents the estimated annual air dose can not exceed 10 mrems for gamma radiation and 20 mrems for beta radiation. Section III establishes that implementation of Section IIbe demonstrated by calculational procedures based upon models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated and that the cumulative effect of all sources and pathways being influenced by the plant be considered. Section IV provides guides on limiting conditions for operation. The licensee shall establish appropriate surveillance and monitoring programs for reporting of rad effluents data, environmental monitoring data and resulting radiation doses and changes in the use of unrestricted areas surrounding the plant. If releases of effluents result in exceeding one-half the annual exposure, there are investigative and reporting requirements.
| |
| The minor corrections to the azimuth and distance data for REMP locations will not impact ODCM calculations or methodologies for evaluating doses to individuals from principal pathways of exposure. The removal of two air sample stations does not impact TMI's ability to meet ODCM requirements from Table 8.1 to sample from 5 air sampling locations in Table 8.4. Table 8.4 still has two additional sample locations beyond the minimum of 5. -
| |
| The changes to actions for offgas radiation monitoring operability will also not change any methods of sampling or calculation of radiological effluents from this pathway. The note clarifying when releases from the waste gas system may occur without the primary radiation monitor operable also will not impact dose calculations from this release path. Changing the word for the iodine sampler in Table 2.1-2 to match NUREG 1301 and deleting the adjectives for the Aux/ Fuel Handling ventilation radiation monitors does not impact their ability to do iodine and particulate sampling for ODCM calculation requirements.

| |
| : 6. Does the ODCM change maintain the accuracy or reliability of effluent, dose, X YES _NO or setpoint calculations?
| |
| Explain: (provide sufficient information including appropriate analyses justifying the ODCM change)
| |
| The changes to the ODCM to change actions associated with the offgas radiation monitor operability, the note/ description clarifications and the REMP location updates will not impact dose calculations. Setpoint calculations for the radiation monitors are unchanged by the change to the required actions for the offgas radiation monitor. The accuracy and reliability of the effluent monitoring is also not negatively impacted. Both existing radiation monitors will be maintained. The alarm setpoints for the RM-A-4 and RM-A-6 gas monitors will not be impacted by the removal of their iodine channels via ECR 06-00061.
| |
| : 7. Does the ODCM change maintain the accuracy of radioactive effluent control. X YES __ NO required by the SAR?
| |
| Explain: (provide sufficient information including appropriate analyses justifying the ODCM change)
| |
| Chapter 11 of the UFSAR, specifically sections 11.2.4 and 11.4.3, were reviewed to determine that these ODCM changes will not impact the accuracy of radioactive effluent control required by the SAR. As stated before the revision to actions required for the offgas radiation monitor operability, the note/ description clarifications and REMP location changes are not changing the release paths of effluents to the environment or any ability to control or calculate doses via these pathways.
| |
| II. If all questions are answered YES, then complete the ODCM Change Determination and implement the Change per this procedure.

TMI Unit 1 Technical Specification Amendment No. 197, dated October 2, 1995 This letter is an AmerGen Energy Company, LLC (AmerGen) request for NRC approval of a proposed commitment revision regarding the operability requirement for the Condenser Vent System Low Range Noble Gas Monitors specified in the existing TMI Unit 1 Offsite Dose Calculation Manual (ODCM). The current ODCM operability requirement applicable to the Condenser Vent System Low Range Noble Gas Monitors fulfills a regulatory commitment in accordance with the NRC Atomic Safety and Licensing Board Order LBP-84-47, dated
| |
| | |
| U. S. Nuclear Regulatory Commission May 25, 2006 Page 2 of 8 October 31, 1984 (Reference 1), which authorized the return to service of the TMI Unit 1 steam generators with the kinetic expansion repair technique. In accordance with the AmerGen commitment management program, which implements the commitment change guidance specified in NEI 99-04, Rev. 0, "Guidelines for Managing NRC Commitment Changes," dated July 1999, the proposed commitment change modifies the method of compliance specifically defined in the Order (Reference 1), and therefore requires NRC prior approval.
| |
| The Condenser Vent System Low Range Noble Gas Activity Monitors provide data for determination of steam generator primary-to-secondary leakage rate. The existing TMI Unit 1 ODCM requires a minimum of two (2) Low Range Noble Gas Activity Monitors (RM-A5Lo and a suitable equivalent) to-be operable when condenser vacuum is established, and allows continued operation with one (1) monitor for up to 28 days. TMI Unit 1 currently utilizes monitors RM-A5Lo and RM-A15. After 28 days, or if one operable monitor does not. remain in service or is not placed in service within 1 hour, plant shutdown is required in accordance with TMI Unit 1 Technical Specification 3.0.1. The proposed commitment revision modifies the minimum channels required to be operable from two (2) channels to one (1) channel, and will allow continued plant operation for up to 14 days with both Condenser Vent System Low Range Noble Gas Activity Monitors inoperable, provided sampling and analysis actions are implemented. This proposed commitment change will eliminate outdated requirements, provide a primary-to-secondary leakrate monitoring regimen consistent with PWR industry standards and EPRI Guidelines as implemented by NEI 97-06, as well as prevent unnecessary plant transients if both monitors are temporarily out of service. Additionally, the proposed compensatory actions are consistent with other operating plant requirements for steam generator primary-to-secondary leakage monitoring.
| |
| Background and Requirements. of NRC ASLB Order.LBP-84-47 The current TMI Unit 1 Operating License Condition 2.c.(8), "Repaired Steam Generators,"
| |
| requires a plant shutdown if primary-to-secondary leak rate exceeds 0.1 gpm above baseline leakage. This license condition supported TMI Unit 1 restart with the kinetic expansion repairs on the OTSG tubes. The NRC Atomic Safety and Licensing Board (ASLB) Initial Decision, dated October 31, 1984, Section II.A, regarding proceedings related to the TMI-1 kinetic expansion repairs to the OTSG tubes and the ability to detect a primary-to-secondary leak rate of 0.1 gpm, as specified in the TMI-1 License Condition 2.c.(8), directed that redundancy be supplied in the form of a duplicate RM-A5 system or suitable equivalent of comparable sensitivity and response time. The ASLB further directed that the Technical Specifications (TS) be modified to permit plant operation for a maximum of 28 days with one of these duplicate systems inoperable, and to require plant shutdown ifboth of these systems are inoperable. As an alternative, the ASLB directed that the RM-A5 system must be operable at all times during plant operation.
| |
| The resulting NRC ASLB Order LBP-84-47 (Reference 1) authorized the USNRC Director of Nuclear Reactor Regulation to issue to TMI Unit 1 an operating license amendment that revised the Technical Specifications to recognize steam generator tube repair techniques other than plugging, specifically the kinetic expansion tube repair technique. This authorization was subject to conditions imposed by the Board in the Order, which specified: "A duplicate RM-A5 system or suitable equivalent of comparable sensitivity and response time for monitoring radioactive gas in the secondary system shall be installed. The Technical Specifications shall
| |
| | |
| U. S. Nuclear Regulatory Commission May 25, 2006 Page 3 of 8 be modified to permit plant operation for a maximum of 28 days with one of these duplicate systems inoperable, and to require plant shutdown if both of these systems are inoperable. As an alternative to the installation of a duplicate system, we direct that the RM-A5 system must be operable at all times during plant operation."
| |
| TMI Unit 1 letter to the NRC (Reference 2), dated November 19, 1984, clarified that TMI Unit 1 planned to provide a backup to RM-A5Lo using an existing portable monitor, RM-A1'3 having comparable sensitivity and response time to RM-A-5, and thus meeting the Order requirement of a suitable equivalent system which may be used for up to 28 days in the event that RM-A5Lo is inoperable. This letter further identified that TMI Unit 1 TS 3.21.2 would be changed to address the Board Order to implement the TS 28-day allowed outage time for RM-A5 and the plant shutdown action statement if both systems are inoperable.
| |
| The NRC issued TMI Unit I TS Amendment No. 103, dated December 21, 1984 (Reference 3),
| |
| which permitted the return of the steam generators to operation in response to TMI Unit 1 amendment request of May 9, 1983, and in accordance with the ASLB Order LBP-84-47, dated October 31, 1984 (Reference 1). The NRC. amendment specifically states that the revised TS included in this amendment incorporate the conditions imposed by the Board (identified above),
| |
| and that the revised TS included in the amendment conformed with the condition imposed by the Board. The amendment also accepted the proposed alternative suitable equivalent system (portable monitor RM-A13) to RM-A5Lo, described above. The TS 3.21.2 requirement specified an allowed radiation monitor outage time of 28 days and specified a plant shutdown action statement in accordance with TS 3.0.1. TS 3.21.2 Bases specifically identified that the RM-A5 and suitable equivalent monitors provide data for determination of steam generator primary-to-secondary leakage rate, and that the channel operability requirements were based on ASLB Order dated October 31, 1984. The use of portable monitor RM-A1 3 was subsequently changed to permanently installed monitor RM-A-1 5, which continues to meet the suitable equivalent criteria to this day.
| |
| These TS 3.21.2 requirements were subsequently relocated to the ODCM in TMI Unit 1 TS Amendment No. 197, dated October 2, 1995 (Reference 7), which administratively relocated the TS Radiological Effluent Monitoring requirements to the ODCM in accordance with the guidance contained in NRC Generic Letter 89-01 and NUREG-i 430. The operability requirements and action statements applicable to RM-A5 and suitable equivalent monitors, as currently specified in the TMI-1 ODCM, Table 2.1-2 and associated Bases, remained unchanged from the requirements addedto the TMI Unit 1 TS 3.21.2 in Amendment No. 103 in accordance with Reference 1, described above.
| |
| Proposed Alternative Markups of the revised TMI Unit 1 ODCM text are provided in Attachment 1 to illustrate implementation of the proposed commitment revision regarding the operability requirement for the Condenser Vent System Low Range Noble Gas Monitors. The following is a summary of the proposed ODCM text.

| |
| ODCM Page 29, Table 2.1-2, Action 32 - Revises the Action Statement to allow continued plant operation for up to 14 days with both Condenser Vent System Low Range Noble Gas Activity Monitors inoperable, provided grab samples are taken and analyzed in accordance with the proposed specified minimum frequency requirements of Table 1 of Action 32 in order to quantify primary-to-secondary leakrate. After 14 days, if one operable channel is not returned to service, within 1 hour the provisions of Technical Specification 3.0.1 apply, which would require that the plant be in hot standby within the next 6 hours, hot shutdown within the following 6 hours, and cold shutdown within the subsequent 24 hours. Action 32 is also revised to state that any inoperable channel(s) should be restored to operability as rapidly as practical.
| |
| Reason for Change Request This proposed commitment change will eliminate outdated requirements, provide a primary-to-secondary leakrate monitoring regimen consistent with PWR industry.standards and EPRI Guidelines as implemented by NEI 97-06, as well as prevent unnecessary plant transients if both monitors are temporarily out of service. Additionally, the proposed compensatory actions are consistent with other operating plant requirements for steam generator primary-to-secondary leakage monitoring.
| |
| Justification of Proposed Change In accordance with ASILB Order LBP-84-47 (Reference 1), the TMI Unit 1 Offsite Dose Calculation Manual (ODOM), Table 2.1-2, "Radioactive Gaseous Process and Effluent Monitoring Instrumentation," Item 4.a, currently requires a minimum of two operable channels on the CondenserVent System Low Range Noble Gas Activity Monitor. If one channel becomes inoperable, the ODCM allows 28 days for the inoperable channel to be restored.
| |
| However, if no operable channels are in service, after one hour the provisions of Technical Specification 3.0.1 apply. TMI Unit 1 Technical Specification 3.0.1 states that in the event a Limiting Condition for Operation (LCO) is not met, within one hour action shall be initiated to place the unit in at least HOT STANDBY within the next 6 hours, and at least HOT SHUTDOWN within the following 6 hours, and at least COLD SHUTDOWN within the subsequent 24 hours.
| |
| In summary, ifboth Condenser Vent System Low Range Noble Gas Activity Monitors are inoperable, the plant must begin to shut down within 1 hour.
| |
| The primary purpose of the TMI Unit I Condenser Vent System Low Range Noble Gas Activity Monitors (RM-A-5 and RM-A-1 5) is to detect radioactive gases in the secondary system. The amount of gas detected by the monitors is used to evaluate the plant's steam generator tube leakage (i.e., to detect primary-to-secondary leakage and to quantify the primary-to-secondary leakrate).
| |
| TMI Unit 1 plans to continue to use the two low range channels (RM-A5 and RM-A15) in accordance with the ODCM, and to revise the minimum channels operable requirement from two (2) channels to one (1) channel. The proposed action statement also specifies that inoperable Condenser Vent System Low Range Noble Gas Activity Monitor channels should be restored to operability as soon as practical. TMI Unit 1 also proposes to modify the commitment
| |
| | |
| U. S. Nuclear Regulatory Commission May 25, 2006 Page 5 of 8 implementation to require that if no operable Condenser Vent System Low Range Noble Gas Activity Monitor channel is in service, the plant may remain in service for up to 14 days ifthe specified sampling and analysis actions are implemented. The intent of this commitment change is to eliminate outdated requirements, provide a primary-to-secondary leakrate monitoring regimen consistent with PWR industry standards and EPRI Guidelines as implemented by NEI 97-06, as well as prevent unnecessary plant transients if both radiation monitors RM-A5 and RM-A15 are temporarily out of service. Additionally, the proposed compensatory actions are consistent with other operating plant requirements for steam generator primary-to-secondary leakage monitbring. It is expected that the revised commitment requirements will be infrequently used, as the operating history of the RM-A-5 and -15 monitors since the 1980's has shown that the probability of their simultaneous failure is low. Additionally, the sample lines to RM-A5 and RM-A15 have been modified to eliminate single point vulnerabilities that resulted in both detectors being declared inoperable on March 10, 2006.
| |
| TMI Unit 1 proposes to implement the proposed commitment change by modifying the ODCM so that a sampling regimen consistent with the EPRI PWR Primaryto Secondary Leak Guidelines (Reference 4) is implemented if no Condenser Vent System Low Range Noble Gas Activity monitor is available. The current revision of the EPRI Guidelines provides the suggested sampling regimen in Section 3.2.2, entitled "No Available Continuous Radiation Monitor." The following is a summary of the proposed TMI Unit 1 ODCM text consistent with the above EPRI Guidelines:
| |
| Entry Requirement: There are no operable channels on the Condenser Vent System Low Range Noble Gas Activity Monitor.
| |
| Rewuired Actions:
| |
| : 1. If there is no operable channel of the Condenser Vent System Low Range Noble Gas Activity Monitor for a period of 14 days" within one hour action shall be initiated to place the unit in at least HOT STANDBY within the next 6 hours, and at least HOT SHUTDOWN within the following 6 hours, and at least COLD SHUTDOWN within the subsequent 24 hours.
| |
| : 2. Ifthe primary-to-secondary leakrate was unstable* or was indicating an increasing trend at the initial time when there was no operable channel of the Condenser Vent System Low Range Noble Gas Activity Monitor, analyze grab samples of the reactor coolant system and Condenser OffGas once every 4 hours to provide an indication of primary-to-secondary leakage, and subsequent sample frequency shall be in accordance with Table 1: based on the last sample result. Otherwise, analyze grab samples of the reactor coolant system and Condenser OffGas to provide an indication of primary-to-secondary leakage at the minimum frequency indicated in Table 1, below:

| |
| *unstable is defined as > 10% increase during a 1 hourperiod, as stated in the EPRI Guidelines.
| |
| : 3. Return a channel of the Condenser Vent System Low Range Noble Gas Activity Monitor to operability as rapidly as practical.
| |
| As described above, the proposed TMI Unit 1 sampling regimen is as prescribed in the most recent revision of the EPRI PWR.Primaryto Secondary Leak Guidelines. These guidelines are industry standards and are based on considerable operating experience at Pressurized Water Reactors (PWRs) to ensure that the likelihood of propagation of steam generator tube flaws to tube rupture is minimized. The Guidelines are used by numerous plants and have been cited in the NRC's recent model safety evaluation for the Technical Specification improvements under TSTF-449, Rev. 4 for steam generator tube integrity (Reference 5). The EPRI Guidelines' discussion of the use of grab sampling when no radiation monitors are available for on-line quantification of primary-to-secondary leakage is also discussed in the NRC Inspection Manual for "Steam Generator Tube Primary-to-Secondary Leakage." The proposed sampling and analysis actions will be performed using existing plant equipment and procedures. No plant modifications are needed to implement the specified actions.
| |
| The TMI Unit 1 steam generator upper tubesheet expansions were repaired by a kinetic expansion process in the 1980's. At the time of these ASLB hearings, the PWR industry had limited operating experience with steam generator tube expansion repairs. At the time the repairs were "a new, large-scale application of the kinetic expansion process" and there was "no directly relevant experience" in the PWR industry (Reference 1, Page 1416). The additional radiation monitor channel, and the requirement for plant shutdown after one hour in the event that no radiation monitor is available to monitor the plant's Condenser Vent, were additional conservative measures with which to assess the success of the kinetic expansion repairs.
| |
| | |
| U. S. Nuclear Regulatory Commission May 25, 2006 Page 7 of 8 Since the early 1980's the PWR industry has obtained considerable experience with tube expansion repairs, including several different types of expansion repair methods. In addition, the TMI Unit 1 kinetic expansions have proven to be successful, leak-tight, and flaw-tolerant repairs. The plant has operated approximately 17 Effective Full Power Years (EFPY) since the kinetic expansions were installed. Since 1997, the maximum primary-to-secondary leakage, experienced through the TMI Unit 1 steam generator tubes, including their kinetic expansion joints, has typically been less than 1 gallon per day (GPD).
| |
| In addition to the fact that the kinetic expansions were an effective repair, a significant number of kinetic expansion inspections have been performed to monitor their condition. Each (i.e.,
| |
| 100%) of the plant's inservice kinetic expansions was examined with rotating coil eddy current probes during the plant's last outage in the fall of 2005. These examinations were conducted in accordance with the requirements of AmerGen ECR #02-01121, which was approved by the NRC in Reference 6. More than 60,000 examinations of the plant's kinetic expansions have been performed over the last four refueling outages. These examinations and the analyses of the examination results have determined that significant active degradation in the kinetic expansions' required lengths is not occurring. In addition, the kinetic expansions are relatively flaw-tolerant since: (1) the expansion area is captured within the steam generator upper tubesheets, and (2),the expansions are not subjected to bending loads or potential loose part impact.
| |
| If the RM-A-5 and -15 radiation monitors are out of service, the proposed sampling regimen will allow evaluation of low levels of primary-to-secondary leakage. Other methods are available to monitor the plant for sizeable primary-to-secondary leaks, including MakeUp Tank level changes, Main Steam Une Radiation Monitors RM-G-26 and -27, Reactor Coolant System Pressurizer level changes, and Condenser Exhaust Hi-Range Radiation Monitor RM-A-5Hi.
| |
| There is no estimated risk increase under the plant's risk model associated with the loss of RM-A-5 and RM-A-15 operability, as these monitors are not included as part of any assumptions made in the PRA model regarding Steam Generator Tube Rupture (SGTR) or RCS Leak Rate detection. Steam generator tube ruptures are considered to be the full offset rupture of one tube. For leaks of this size it is assumed that RM-G26 and RM-G27 as well as RCS Pressure and OTSG Level and Feed Rates provide the necessary SGTR detection needed to satisfy the assumptions made by the PRA model. It should be noted that RM-G26 and RM-G27 are capable of some detection of OTSG Tube leakage smaller than what is assumed during a full offset rupture. In addition, particularly small break sizes or leaks that are within the makeup capacity of the normal charging system and would therefore not result in an automatic reactor trip, are not included in the initiating event categories of the plants risk models. For such small leaks, the plant would be manually shutdown in a controlled fashion, and cooled down and depressurized for repairs, regardless of the leak/break location in the steam generator tubes.
| |
| The proposed commitment change provides a limit on the maximum length of time (i.e,, 14 days) during which the plant can remain at power without an operable Condenser Vent System Low Range Noble Gas Activity monitor channel. The probability of a significant primary-to-secondary leak event occurring during this short duration is low. TMI Unit 1 has not had a significant primary-to-secondary leak event due to leakage from a kinetic expansion.
| |
| | |
| U. S. Nuclear Regulatory Commission May 25, 2006 Page 8 of 8 Conclusion The proposed commitment change makes no physical changesto the TMI-1 plant and does not alter the TMI Unit 1 Technical Specification or License Condition. maximum allowed primary-to-secondary leak rates at which the plant is required to be shutdown. The intent of the proposed commitment change is to eliminate outdated requirements, provide a primary-to-secondary leakrate monitoring regimen consistent with PWR industry standards and EPRI Guidelines as implemented by NEI 97-06, as well as prevent unnecessary plant transients ifboth monitors RM-A5 and RM-A15 are temporarily out of service. Additionally, the proposed compensatory actions are consistent with other operating plant requirements for steam generator primary-to-secondary leakage monitoring, and following the methodology of the EPRI PWR Guidelines is an acceptable, alternate method of monitoring the plant's primary-to-secondary leakage. The probability of both RM-A-5 and -15 channels becoming inoperable is low. The probability of a primary-to-secondary leak event occurring while both RM-A-5 and -15 channels are inoperable is also low. Thus, nuclear safety and plant operations are not adversely affected by the proposed commitment change.
| |
| We request approval of the proposed commitment change by August 31, 2006, to allow timely update of the affected ODCM requirements.
| |
| This submittal requests approval of a revision to an existing regulatory commitment, and no new regulatory commitments are established by this submittal. If you have any questions or require additional information, please contact David J. Distel at (610) 765-5517.

| Number TMl - Unit I Radioloqical Controls Procedure 6610-PLN-4200.01 T'ite Revision No, Offsite Dose Calculation Manual (ODCM) 25 INTRODUCTION The OFFSITE DOSE CALCULATION MANUAL (ODCM) is a supporting document of the Three Mile Island Nuclear Station (TMI) Unit I and Unit 2 PDMS Technical Specifications and implements TMI radiological effluent controls.
| |
| The ODCM contains the controls, bases, and surveillance requirements for liquid and gaseous radiological effluents.
| |
| In addition, the ODCM describes the methodology and parameters to be used in the calculation of off-site doses due to radioactive liquid and gaseous effluents. This document also describes the methodology used for calculation of the liquid and gaseous effluent monitoring instrumentation alarmltrip set points. Uquid and Gaseous Radwaste Treatment System configurations are also included.
| |
| The ODCM also is used to define the requirements for the TMI radiological environmental monitoring program (REMP) and contains a list and graphical description of the specific sample locations used in the REMP.
| |
| The ODCM is maintained atthe Three Mile Island (TMI) site for use as a reference guide and training document of accepted methodologies and calculations. Changes in the calculation methods or parameters will be incorporated into the ODCM to ensure the ODCM represents the present methodology in all applicable areas. Changes to the ODCM will be implemented in accordance with the TMJ-1 and TMI-2 PDMS Technical Specifications.
| |
| The ODCM follows the methodology and models suggested by NUREG-0133, and Regulatory Guide 1.109, Revision 1 for calculation of off-site doses due to plant effluent releases. Simplifying assumptions have been applied in this manual where applicable to provide a more workable document for implementation of the Radiological Effluent Controls requirements.
| |
| TMI implements the TMI Radiological Effluent Controls Program and Regulatory Guide 1.21, Revision 1 (Annual Radioactive Effluent Release Report) requirements by use of a computerized system used to determine TMI effluent releases and to update cumulative effluent doses.

| transient conditions or other ongoing surveillance or maintenance activities. It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are specified to be performed at least once each REFUELING INTERVAL. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed once each REFUELING INTERVAL. Likewise, it is not the intent that REFUELING INTERVAL surveillances be performed during power operation unless it is consistent with safe plant operation. The limitation of Section 1.13 is based on engineering judgment and the recognition that the most probable result of any particular surveillance being performed Is the verification of conformance with the Surveillance Requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.

For dissolved or entrained noble gases, the concentration shall be limited to 3 x 10.3 uCi/cc total activity.
| |
| APPLICABILITY: At all times ACTION:
| |
| With the concentration of radioactive material released from the unit to unrestricted areas exceeding the above limits, immediately restore concentrations within the above limits.
| |
| BASES This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluent from the unit to unrestricted areas will be less than ten times the concentration levels specified in 10 CFR Part 20.1001-20.2401, Appendix B, Table 2. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will not result in exposures with (1) the Section Il.A design objectives of Appendix 1, 10 CFR Part 50, to a MEMBER OF THE PUBLIC and (2) the limits of 10 CFR Part 20.1301 to the population. The concentration limit for noble gases is based upon the assumption the Xe-135 is the controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

| : a. With the calculated dose from the release of radioactive materials in liquid effluents exceeding any of the above limits, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce the releases of radioactive materials in liquid effluents during the remainder of the current calendar quarter and during the subsequent 3 calendar quarters so that the cumulative dose or dose commitment to any individual from such releases during these four calendar quarters is within 3 mrem to the total body and 10 mrem to any organ. This Special Report shall also include (1) the result of radiological analyses of the drinking water source, and (2) the radiological impact on finished drinking water supplies with regard to the requirements of 40 CFR 141, Safe Drinking Water Act.
| |
| BASES This control and associated action is provided to implement the requirements of Sections l.A, ll.A, and IV.A of Appendix 1, 10 CFR Part 50. The Control implements the guides set forth in Section II.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable". Also, for fresh water sites with drinking water supplies which can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 10 CFR 20. The dose calculations in the ODCM Implement The requirements in Section IIl.A. of Appendix I that conformance with the guides of Appendix I is to be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "'Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October, 1977, and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April, 1977.

| |
| I1. Explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or subsystems, and the reason for inoperability,
| |
| : 2. Action(s) taken to restore the inoperable equipment to OPERABLE status, and,
| |
| : 3. A summary description of action(s) taken to prevent a recurrence.
| |
| BASES The requirement that the appropriate portions of this system be used, when specified, provides assurance that the releases of radioactive materials in liquid effluents will be kept as low as is reasonably achievable. This control implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section II.D of Appendix I to 10 CFR Part 50. The intent of Section lD. is to reduce effluents to as low as is reasonably achievable in a cost effective manner. This control satisfies this intent by establishing a dose limit which is a small fraction (25%) of Section II.A of Appendix 1,10 CFR Part 50 dose requirements. This margin, a factor of 4, constitutes a reasonable reduction.

| |
| This specification is provided to ensure that the dose from radioactive materials in gaseous effluents at and beyond the SITE BOUNDARY will be within the annual dose limits of 10. CFR Part 20. The annual dose limits are the doses associated with 10 times the concentrations of 10 CFR Part 20, Appendix B, Table 2, Column 1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC, either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the limits specified in Appendix B, Table 2 of 10 CFR Part 20.1302. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the exclusion area boundary. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the total body or to less than or equal to 3000 mrem/year to the skin.

| |
| The dose to a MEMBER OF THE PUBLIC from Iodine-131, Iodine-133, Tritium, and all radionuclides in particulate form with half lives greater than 8 days, in gaseous effluents released from the unit to areas at and beyond the SITE BOUNDARY shall be limited to the following:
| |
| : a. During any calendar quarter: less than or equal to 7.5 mrem to any organ, and

| |
| With the calculated dose from the release of Iodine-131, Iodine-133, Tritium, and radionuclides in particulate form with half lives greater than 8 days, in gaseous effluents exceeding any of the above limits, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which identifies the cause(s) for exceeding the limit and defines the corrective actions that have been taken to reduce the releases and the proposed corrective actions to be takento assure that subsequent releases will be in compliance with the above limits.
| |
| BASES This control applies to the release of radioactive materials in gaseous effluents from TMI-1.
| |
| This control and associated action is provided to implement the requirements of Section II.C, III.A and IV.A of Appendix I, 10 CFR Part 50. The Controls are the guides set forth in Section Il.C of Appendix 1. The ACTION statement provides the required operating flexibility and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable." The ODCM calculationai methods specified in the surveillance requirements implement the requirements in Section IlI.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The ODCM calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October, 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July, 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate controls for iodine-1 31, iodine-1 33, tritium and radionuclides in particulate form with half lives greater than 8 days are dependent upon the existing radionuclide pathways to man, inareas at and beyond the SITE BOUNDARY. The pathways that were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.

The appropriate portions of the GASEOUS RADWASTE TREATMENT SYSTEM shall be used to reduce radioactive materials in the gaseous waste prior to their discharge when the monthly projected gaseous effluent air doses due to untreated gaseous effluent releases from the unit would exceed 0.2 mrad for gamma radiation and 0.4 mrad for beta radiation. The appropriate portions of the VENTILATION EXHAUST TREATMENT SYSTEM shall be used to reduce radioactive materials in gaseous waste prior to their discharge when the monthly projected doses due to gaseous effluent releases from the site would exceed 0.3 mrem to any organ.
| |
| APPLICABILITY: At all times.
| |
| ACTION:
| |
| : a. With the GASEOUS RADWASTE TREATMENT SYSTEM and/or the VENTILATION EXHAUST TREATMENT SYSTEM inoperable for more than a month or with gaseous waste being discharged without treatment and in excess of the above limits, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which includes the following information:
| |
| : 1. Identification of the inoperable equipment or subsystems and the reason for inoperability,
| |
| : 2. Action(s) taken to restore the inoperable equipment to OPERABLE status, and
| |
| : 3. A summary description of action(s) taken to prevent a recurrence.
| |
| BASES The use of the GASEOUS RADWASTE TREATMENT SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that gaseous effluents are treated as appropriate prior to release to the environment. The appropriate portions of this system provide reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable." This control implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section 11.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the guide set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents, 37

| |
| AVAILABILITY: At all times.
| |
| ACTION:
| |
| Whenever the concentration of hydrogen in the Waste Gas Holdup System is greater than or equal to 4% by volume, and:
| |
| : a. The concentration of oxygen in the Waste Gas Holdup System is greater than 2% by volume, but less than 4% by volume, without delay begin to reduce the oxygen concentration to within its limit.
| |
| : b. The concentration of oxygen in the Waste Gas Holdup System is greater than or equal to 4% by volume, immediately suspend additions of waste gas to the Waste Gas Holdup System and without delay begin to reduce the oxygen concentration to within its limit.
| |
| BASES:
| |
| Based on experimental data (Reference 1), lower limits of flammability for hydrogen is 5% and for oxygen is 5% by volume. Therefore, ifthe concentration of either gas is kept below it lower limit, the other gas may be present in higher amounts without the danger of an explosive mixture.
| |
| Maintaining the concentrations of hydrogen and oxygen such that an explosive mixture does not occur inthe waste gas holdup system provides assurance that the release of radioactive materials will be controlled in conformance with the requirements of General Design Criterion 60 of Appendix A to 10 CFR 50.

| |
| The quantity of radioactivity contained in each waste gas decay tank shall be limited to less than or equal to 8800 curies noble gases (considered as Xe-133).
| |
| APPLICABILITY: At all times.
| |
| ACTION:
| |
| : a. With the quantity of radioactive material in any waste gas decay tank exceeding the above limit, immediately suspend all addifions of radioactive material to the tank and within 48 hours reduce the tank contents to within the limit.
| |
| BASES Restricting the quantity of radioactivity contained in each waste gas decay tank provides assurance that in the event of an uncontrolled release of the tanks contents, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest exclusion area boundary will not exceed 0.5 rem. This is consistent with Standard Review Plan 15.7.1, '"Waste Gas System Failure."

| |
| The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC, due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrem to the total body or any organ except the thyroid, which shall be limited to less than or equal to 75 mrem.
| |
| APPLICABILITY: At all times.
| |
| ACTION:
| |
| With the calculated dose from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of Controls 2.2.1.2.a, 2.2.1.2.b, 2.2.2.2.a, 2.2.2.2.b, 2.2.2.3.a, or, 2.2.2.3.b, calculations should be made including direct radiation contributions from the unit and from outside storage tanks to determine whether the above limits of Control 2.2.3.1 have been exceeded. If such is the case, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which defines the correcfive action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits.

| Offsite Dose Calculation Manual (ODCM) 25 10 CFR Part 20.2203(b), shall include an analysis which estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. if the estimated dose(s) exceed the above limits, and if the release condition resulting in violation of 40 CFR 190 has not already been corrected, the Special Report shall include a request for a variance in accordancewith the provisions of 40 CFR 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.
| |
| BASES This control is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20.1301(d). This control requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrem to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the reactor units and outside storage tanks are kept small. The Special Report will describe a course of action that should result inthe limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the member of the public from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any member of the public is estimated to exceed the requirements of 40 CPR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 10 CFR Part 20.2203(b),'is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Controls 2.2.1.1 and 2.2.2.1. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in.carrying out any operation that is part of the nuclear fuel cycle.

| |
| ExV x2.22 X1Q 6 x Y xexp (-7,At)
| |
| Where:
| |
| LLD is the "a priori" lower limit of detection as defined above (as microcurie per unit mass or volume),

| Offsite Dose Calculation Manual (ODCM) _ __ 25 2.2 Radioactive Effluent Controls 2.2.1 Liquid Effluent Controls 2.2.1.1 Liquid Effluent Concentration CONTROL:
| |
| The concentration of radioactive material released at anytime from the unit to unrestricted areas shall be limited'to ten times the concentrations specified in 10 CFR Part 20.1001-20.2401, Appendix B, Table 2, Column 2.
| |
| APPLICABILITY: At all times ACTION:
| |
| With the concentration of radioactive material released from the unit to unrestricted areas exceeding the above limits, immediately restore concentrations within the above lit its.
| |
| BASES This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluent from the unit to unrestricted areas will be less than ten times the concentration levels specified in 10 CFR Part 20.1001-20.2401, Appendix B, Table 2. These Controls permit flexibility under unusual conditions, which may temporarily result in higher than normal releases, but still within ten times the concentrations, specified in 10 CFR 20.
| |
| It is expected that by using this flexibility under unusual conditions, and exerting every effort to keep levels of radioactive material in liquid wastes as low as practicable, the annual releases will not exceed a small fraction of the annual average concentrations spIecified in 10 CFR 20. As a result, this Control provides reasonable assurance that the resulting annual exposure to an individual in off-site areas will ulot exceed the design objectives of Section I.A of Appendix I to 10 CFR Part 50, which were established as requirements for the cleanup of TMI-2 in the NRC's Statement of Policy of April 27, 1981.
| |
| 2.2.1.2 Uquid Effluent Dose CONTROL The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released from the unit to the SITE BOUNDARY shall be limited: I
| |
| : a. During any calendar quarter to less than or equal to 1.5 mrem to the total body and to less than or equal to 5 mrem to any organ.
| |
| : b. During any calendar year to less than or equal to 3 mrem to the total body and to less than or equal to 10 mrem to any organ.

| Offsite Dose Calculation Manual (ODCM) 25 APPLICABILITY: At all times ACTION:
| |
| : a. With the calculated dose from the release of radioactive materials in liquid effluents exceeding any of the above limits, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce the releases of radioactive materials in liquid effluents during the remainder of the current calendar quarter and during the subsequent 3 calendar quarters so that the cumulative dose or dose commitment to any individual from such releases during these four calendar quarters is within 3 mrem to the total body and 10 mrem to any organ. This Special Report shall also include (1) the result of radiological analyses of the drinking water source, and (2) the radiological impact on finished drinking water supplies with regard to the requirements of 40 CFR 141, Safe Ddnking Water Act.
| |
| BASES This Control requires that the dose to offsite personnel be limited to the design objectives of Appendix I of 10 CFR Part 50. This will assure the dose received by the public during PDMS is equivalent to or less than that from a normal operating reactor. The limits also assure that the environmental impacts are consistent with those assessed in NUREG-0683, the TMI-2 Programmatic Environmental Impact Statement (PEIS). The ACTION statements provide the required flexibility under unusual conditions and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable". The dose calculations in the ODCM implement the requirements in Section IIt.A. of Appendix I that conformance with the guides of Appendix I is to be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October, 1977, and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I,"April, 1977.

| |
| The appropriate portions of the liquid radwaste treatment system shall be used to reduce the radioactive materials in liquid wastes prior to their discharge when the projected doses due to the liquid effluent from the unit to unrestricted areas would exceed 10.06 mrem to the total body or 0.2 mrem to any organ in any calendar month APPLICABILITY: At all times ACTION:
| |
| : a. With radioactive liquid waste being discharged without treatment and in excess of the above limits, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which includes the following information:
| |
| : 1. Explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or subsystems, and the reason for inoperability,
| |
| : 2. Action(s) taken to restore the inoperable equipment to OPERABLE status, and,
| |
| : 3. A summary description of action(s) taken to prevent a recurrence.
| |
| BASES The requirement that the appropriate portions of this system (shared with TMI-1) be used, when specified, provides assurance that the releases of radioactive materials in liquid effluents will be kept as low as is reasonably achievable. This control implements the requirements of 10 CFR Part 50.36a, General Design Criterionl 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section ll.D of Appendix I to 10 CFR Part 50. The Intent of Section Il.D. is to reduce effluents to as low as is reasonably achievable in a cost effective manner, This control satisfies this intent by establishing a dose limit which is la small fraction (25%) of Section II.A of Appendix 1,10 CFR Part 50 dose requirements. This margin, a factor of 4, constitutes a reasonable reduction.

| The dose rate due to radioactive materials released in gaseous effluent from the site shall be limited to the following:
| |
| : a. For noble gases: less than or equal to 500 mremlyr to the total body and less than or equal to 3000 mrem/yr to the skin, and
| |
| : b. For tritium and all radionuclides in particulate form with half lives greater than 8 days: less than or equal to 1500 mrem/yr to any organ.
| |
| APPLICABILITY: At all times.
| |
| ACTION:
| |
| With the release rate(s) exceeding the above limits, immediately decrease the release rate to comply with the above limit(s).
| |
| BASES The control provides reasonable assurance that the annual dose at the SITE BOUNDARY from gaseous effluent from all units on the site will be within the annual dose limits of 10 CFR Part 20 for unrestricted areas. At the same time, these Controls permit flexibility under unusual conditions, which may temporarily result in higher than the design objective levels, but still within the dose limits specified in 10 CFR 20 and within the design objectives of Appendix I to 10 CFR 50. It is expected that using this flexibility under unusual conditions, and by.exerting every effort to keep levels of radioactive material in gaseous wastes as low as practicable, the annual releases will not exceed a small fraction of the annual dose limits specified in 10 CFR 20 and will not result in doses which exceed the design objectives of Appendix I to 10 CFR 50, which were endorsed as limits for the cleanup of TMI-2 by the NRC's Statement of Policy of April 27, 1981. These gaseous release rates provide reasonable assurance that radioactive material discharged in gaseous effluent will not result in the exposure of a MEMBER OF THE PUBLIC in an unrestricted area, either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the values specified in Appendix B, TabJe 2 of 10 CFR Part 20. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the exclusion area boundary.

The absence of iodine ensures that the corresponding thyroid dose rate above background to a child via th.e inhalation pathway is less than or equal to 1500 mrem/yr (NUREG 1301), thus there is no need to specify dose rate limits for these nuclides.

| |
| This control and associated action is provided to implement the requirements of Section II.C, III.A and IV.A of Appendix 1,10 CFR Part 50. The Controls are the guides set forth in Section I1.C of Appendix 1. The ACTION statement provides flexibility during unusual conditions and at the same time implements the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable." The ODCM calculational methods specified in the surveillance requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The ODCM calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October, 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July, 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate controls for iodine-131, iodine-133, tritium and radionuclides in particulate form with half lives greater than 8 days are dependent upon the existing radionuclide pathways to man, in areas at and beyond the SITE BOUNDARY. The pathways that were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man. The absence of iodines at the site eliminates the need to specify dose limits for these nuclides.

| With the calculated dose from the release of radioactive materials in liquid or gaseous effluents exceeding twice the limits of Controls 2.2.1.2.a, 2.2.1.2.b, 2.2.2.2.a, 2.2.2.2.b, 2.2.2.3.a, or, 2.2.2.3.b, calculations should be made including direct radiation contributions from the unit and from outside storage tanks to determine whether the above limits of Control 2.2.3.1 have been exceeded. If such is the case, prepare and submit to the NRC Region I Administrator within 30 days, a Special Report which defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and includes the schedule for achieving conformance with the above limits. This Special Report, as defined in 10 CFR Part 20.2203(b), shall include an analysis which estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. If the estimated dose(s) exceed the above limits, and ifthe release condition resulting in violation of 40 CFR 190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40 CFR 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.

| Offsite Dose Calculation Manual (ODCM) 25 BASES This control is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20.1301(d). This control requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrem to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the reactor units and outside storage tanks are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the member of the public from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any member of the public is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 10 CFR Part 20.2203(b), is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Controls 2.2.1.1 and 2.2.2.1. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

| The value of Sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the samples. Typical values of E, V, Y, and At shall be used in the calculation. The background count rate is calculated from the background counts that are determined to be with + one FWHM (Full-Width-at-Half-Maximum) energy band about the energy of the gamma-ray peak used for the quantitative analysis for that radionuclide.

The alert set point value is set to ensure that advance warning occurs prior to exceeding any limits. The high alarm set point value is such that if it were exceeded, it would result in concentrations exceeding ten times the 10 CFR 20 concentrations for the unrestricted area.
| |
| f= flow set point as measured at the radiation monitor location, in volume per unit time, but in the same units as F below.
| |
| F = flow rate of dilution water measured prior to the release point, in volume per unit time.
| |
| The set point concentration is reduced such that concentration contributions from multiple release points would not combine to exceed ten times 10 CFR 20 concentrations. The set point concentration is converted to set point scale units using appropriate radiation monitor calibration factors.

| Offsite Dose Calculation Manual (ODCM) 25 1.2 TMI Liquid Effluent Release Points and Liquid Radiation Monitor Data TMI-1 has two required liquid radiation monitors. These are RM-L6 and RM-L12. These liquid release point radiation monitors and sample points are shown in Table 1.1. (The TMI outfall radiation monitor, RM-L.7, is also listed for information only.)
| |
| TMI-2 does not have any required liquid radiation monitors, but does utilize RM-L12, and RM-L7 for release of liquid waste.
| |
| 1.2.1 RM-L6 RM-L6 is an off-line system, monitoring radioactive batch discharges from the TMI-1 liquid radwaste system (see Figure 1.1). These batch releases are sampled and analyzed per site procedures prior to release. The release rate is based on releasing one of two Waste Evaporator Condensate Storage Tanks (WECST) at a flow which will add less than 10%,
| |
| of ten times the 10 CFR 20 concentrations [20% for H-31 to radionuclide concentrations in the unrestricted area, including conservative default values for Sr-89, Sr-90, and Fe-56.
| |
| The release flow rate used is the most restrictive of two flow rates calculated for each liquid batch release, per the approved plant procedure.
| |
| Two Dilution Factors (DF) are calculated to ultimately calculate the batch release flow rate. These two DF's are calculated to insure each radionuclide released to the unrestricted area is less than 10 percent of ten times the 10CFR20 radionuclide concentrations, (20% for H-3), and to ensure each liquid batch release boron concentration to the river will not exceed 0.7 ppm.
| |
| The maximum release flow rate is then calculated by dividing the most restrictive (largest)
| |
| DF into 90 percent of the current dilution flow rate of the Mechanical Draft Cooling Tower (MDCT). This conservative flow rate is then multiplied by 0.9 for the allowable flow rate.
| |
| * Calculation of the IOCFR20 concentration DF:
| |
| DF, = Z, (SA-). (10% [20% for H-3] of ten times the IOCFR20 concentration)
| |
| SA Specific Activity of each identified radionuclide
| |
| * Calculation of Boron DF:
| |
| DF 2 = Actual Tank Boron Concentration + 0.7.
| |
| Maximum release flow rate calculation:
| |
| Max Flow = [(MDCT flow gpm
| |
| * 0.9) + (Most Restrictive DF)]
| |
| * 0.9 The dilution flow rate used is the current flow rate at the site. The minimum dilution flow rate is 5000 gpm per the TMI-1 FSAR. This ensures this batch release will meet the following equation.

A value of 3E-3 gCi/ml for dissolved and entrained noble gases shall be used.
| |
| CH. =diluted concentration of H-3 XH-3 =Ten times the concentration for H-3 in the restricted area (10 CFR 20, App. B, Table 2, Col. 2).
| |
| The set points for RM-L6 are based on the maximum release rate (30 gpm), a minimum dilution flow (5000 gpm), and 25% of ten times the 10CFR20 concentration for Cs-137, which is the most limiting radionuclide at a concentration of I.OE-5 uCi/ml. These inputs are used in Equation 1.1 to determine the RM-L-6 High Alarm setpoint for all radionuclides being released. A high alarm on RM-L-6 will close valve WDL-V-257 and terminate any WECST releases to the environment.
| |
| 1.2.2 RM-L12 RM-L12 is an off-line system, monitoring periodic combined releases from the Industrial Waste Treatment System/Industrial Waste Filtration System (IWTSjIWFS). The input to
| |
| )WTS/IWFS originates in TMI-2 sumps, (see Figures 1.1 and 1.2) and the TMI-1 Turbine Building sump (see Figure 1.1). The set points are based on the maximum release rate from both IWTS and IWFS simultaneously, (see Figure 1.1) a minimum dilution flow rate, and 50% of ten times the IOCFR20 concentration for Cs-137, which is the most limiting radionuclide at a concentration of 1E-5 i.Ciml. These inputs are used in equation 1.1 to determine the RM-L1 2 High Alarm set point for all radionuclides being released. A high alarm on RM-L12 will close IWTS and IWFS release valves and trip release pumps to stop the release.
| |
| 1V2.3 RM-L10 RM-LIO was a Nal detector submerged in the TMI-1 Turbine Building Sump. This detector has been removed from service.
| |
| 1.2.4 RM-L7 RM-L7 is not an ODCM required liquid radiation monitor. RM-L7 is an off-line system, monitoring the TMI outfall to the Susquehanna River (see Figures 1.1 and 1.2). This monitor is the final radiation monitor for TMI-1 and TMI-2 normal liquid effluent releases.
| |
| 1.3 Control of Liquid Releases TMI liquid effluent releases are controlled to less than ten times the IOCFR20 concentrations by limiting the percentage of this limit allowable from the two TMI liquid release points. RM-L6 and effluent sampling limit batch releases to less than or equal to 25% for all radionuclides, and RM-L12 and effluent sampling limit releases from TMI-1 and TMI-2 to less than or equal to 50% for Cs-1 37, These radiation monitor set points also include built in meter error factors to further ensure that TMI liquid effluent releases are less than ten times the 10CFR20 concentrations to the environment.

The location of the nearest potable water intake is PP&L Brunner Island Steam Electric Station located downstream of TMI. The use of the flow of the Susquehanna River as the dilution flow is justified based on the complete mixing in the river prior to the first potable water supply, adequately demonstrated by flume tracer die studies and additional liquid effluent release studies conducted using actual TMI-1 tritium releases. Other pathways contribute negligibly at Three Mile Island. The dose contribution from all radionuclides in liquid effluents released to the unrestricted area is calculated using the following expression:
| |
| Dosej=E (At)X (Ci) X AWij X f-) + (AF X X (eq 2.1) where:
| |
| Dose j = the cumulative dose commitment to the total body or any organ, j, from the liquid effluents for the total time period, in mrem.
| |
| At = the length of the time period of actual releases, over which C1 and f are averaged for all liquid releases, in hours.
| |
| C, = the average concentration of radionuclide, i, in undiluted liquid effluent during time period At from any liquid release, in IaCi/ml.
| |
| NOTE For Fe-55, Sr-89, Sr-90, prior to batch releases conservative concentration values will be used in the initial dose calculation based on similar past plant conditions. LLD values are not used in dose calculations.
| |
| f= undiluted liquid waste flow, in gpm.
| |
| FD= plant dilution water ilowrate during the period of release, in gpm FR = actual river flowrate during the period of release or average river flowrate for the month the release is occurring, in gpm.
| |
| DF = dilution factor as a result of mixing effects in the near field of the discharge structure of 0.2 (NUREG 0133) or taken to be 5 based on the inverse of 0.2.
| |
| AWij and AFij = the site-related Ingestion dose commitment factor to the total body or any organ, j, for each identified principle gamma and beta emitter, in mrem/hr per jiCi/mI. AW is the factor for the water pathway and AF is the factor for the fish pathway.

| 2.2 TMI Liquid Radwaste System Dose Calcs Once/Month ODCM Part I Control 2.2.1.3 and TMI-2 PDMS Tech Spec Section 6.7.4.a.6 requires that appropriate portions of the liquid radwaste treatment system shall be used to reduce the radioactive materials in liquid wastes prior to their discharge when the monthly projected doses due to the liquid effluent releases from each unit to unrestricted areas would exceed 0.06 mrem to the total body or 0.2 mrem to any organ in any calendar month. The following calculational method is provided for performing this dose projection.
| |
| At least once per month, the total dose from all liquid releases for the quarter-to-date will be divided by the number of days into the quarter and multiplied by 31. Also, this dose projection shall include the estimated dose due to any anticipated unusual releases during the period for which the projection is made. If this projected dose exceeds 0.06 mrem total body or 0.2 mrem any organ, appropriate portions of the Liquid Radwaste Treatment System, as defined in Section 3.1, shall be used to reduce radioactivity levels prior to release.
| |
| At the discretion of Radiological Engineering, time periods other than the current quarter-to-date may be used to project doses ifthe dose per day in the current quarter-to-date is not believed to be representative of the dose per day projected for the next month.

| |
| NOTE Appendix A contains PI calculational methodology.
| |
| 1500 = annual dose rate limit to any organ from particulates and radioiodines and radionuclides (other than noble gases) with half lives greater than eight days in mrem/yr.
| |
| Dv = highest sector annual average gaseous dispersion factor (XIQ or D/Q) at or beyond the unrestricted area boundary from Table 4.4 for releases from the station vent and Table 4.5 for all other releases.

| Offsite Dose Calculation Manual (ODCM) 25 4.6 Control of Gaseous Effluent Releases TMI gaseous effluent combined releases are controlled (per ODCM Part I for TMI-1 and ODCM Part II for TMI-2) by effluent sampling and radiation monitor set points. These measures assure that releases from the various vents do not combine to produce dose rates at the site boundary exceeding the most restrictive of 500 mrem per year to the total body or 3000 mrem per year to the skin, and 1500 mrem per year to the thyroid. This is done by restricting simultaneous releases and by limiting the dose rates that may be contributed by the various vents at any time. The various vent radiation monitor set points are each based on fractions of the above limits and do not exceed the above limits when summed together. These effluent radiation monitor set points are calculated using the methodology described in equations 4.1.1, or 4.1.2 and 4.2. The actual set points are then listed in TMI-1 Operations Procedure 1101-2.1.
| |
| The radioactive content of each batch of gaseous waste is determined prior to release by sampling and analyses in accordance with ODCM Part I for TMI-1 and ODCM Part I1for TMI-2. The results of pre-release analyses are used with the calculational methods in Sections 4.1 and 4.2 to assure that the dose rates at the site boundary are maintained below the limits in ODCM Part I for TMI-1 and ODCM Part II for TMI-2.
| |
| Post-release analyses of samples composited from batch and continuous releases are performed in accordance with ODCM Part I for TMI-1 and ODCM Part II for TMI-2. The results of the analyses are used to assure that the dose rates at the site boundary are maintained within the limits of ODCM Part I for TMI-1 and ODCM Part 11for TMI-2.

When the monthly projected doses due to the gaseous effluent releases from the site would exceed:
| |
| 0.2 mrad to air from gamma radiation; or 0.4 mrad to air from beta radiation; or 0.3 mrem to any organ.
| |
| The following calculational method is provided for performing this dose projection.
| |
| At least once per month the gamma air dose, beta air dose and the maximum organ dose for the quarter-to-date will be divided by the number of days into the quarter and multiplied by 31. Also, this dose projection shall include the estimated dose due to any anticipated unusual release during the period for which the projection is made. If these projected doses exceed any of the values listed above, appropriate portions of the TMI-1 Gaseous Waste Treatment System, as defined in Section 6.0, or appropriate portions of the TMI-2 Gaseous Effluent Filtration System as shown on Figure 4.5, shall be used to reduce radioactivity levels prior to release.
| |
| At the discretion of Radiological Engineering, time periods other than the current quarter-to-date may be used to project doses if the dose per day in the current quarter-to-date is not believed to be representative of the dose per day projected for the next month.

Default parameter values from Regulatory Guide 1.109 (Rev. 1) and/or actual site specific data can be used where applicable.
| |
| The onsite, on-line computerized system for tracking gaseous effluent dose uses annual average gaseous dispersion factors. As an alternative dose calculational methodology. TMI calculates doses using an advanced class "A" dispersion model called SEEDS (simplified environmental effluent dosimetry system).
| |
| This model incorporates the guidelines and methodology set forth in USNRC Regulatory Guide 1.109, and uses actual hourly meteorological information matched to the time of releases to more accurately assess the dispersion of effluents in the atmosphere. Combining this assessment of dispersion with TMI effluent data for each unit, postulated maximum hypothetical doses to the public are calculated.

With milk or fresh leafy vegetation samples unavailable from one or more of the sample locations required by Table 8.1, identify specific locations for obtaining replacement samples and add them within 30 days to the Radiological Environmental Monitoring Program given in the ODCM. The specific locations from which samples were unavailable may then be deleted from the monitoring program. Pursuant to TMI-1 Tech. Spec. 6.14 and TMI-2 PDMS Tech. Spec. 6.12, submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and table for the ODCM reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples and justifying the selection of the new location(s) for obtaining samples.
| |
| 8.1.4 Bases The radiological monitoring program required by this control provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures of members of the general public resulting from the station operation. This monitoring program implements Section IV B.2 of Appendix I to 10CFR50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. Guidance for this monitoring is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring (Revision 1, November 1979). Program changes may be initiated based on operational experience.
| |
| 8.1.5 Surveillance Requirements The radiological environmental monitoring samples shall be collected pursuant to Table 8.1, from the specific locations given in Tables 8.4 through 8.10 and Maps 8.1 through 8.3, and shall be analyzed pursuant to the requirements of Table 8.1 and the detection capabilities required by Table 8.3.

| |
| 8.2.3 Action
| |
| : a. With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in ODCM Part I Surveillance 3.2.2.3.1, pursuant to ODCM, Part IV, Section 2.0, identify the new location(s) in the next Annual Radioactive Effluent Release Report.
| |
| : b. With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater than at a location from which samples are currently being obtained in accordance with Table 8.1, add the new location(s) within 30 days to the Radiological Environmental Monitoring Program given in the ODCM. The sampling location(s), excluding the control station location, having the lowest calculated dose or dose commitment(s), via the same exposure pathway, may be deleted from this monitoring program after October 31 of the year in which this Land Use Census was conducted. Pursuant to TMI-1 Tech. Spec. 6.14 and TMI-2 PDMS Tech. Spec. 6.12, submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and table(s) for the ODCM reflecting the new location(s) with information supporting the change in sampling locations.

| Offsite Dose Calculation Manual (ODCM) 25 8.2.4 Bases This Control is provided to ensure that changes in the use of unrestricted areas are identified and modifications to the monitoring program are made if required by the results of this census. The best information from the door-to-door survey, aerial surveys, or consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR 50. Restricting the census to gardens of greater than 500 square feet (50 m2) provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/yr) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used: 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.
| |
| 8.2.5 Surveillance Requirements The Land Use Census shall be conducted during the growing season at least once per 12 months, using that information that will provide the best results, such as by a door-to-door survey, aerial survey, or by consulting local agricultural authorities. The results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report pursuant to ODCM, Part IV,Section 1.0.

| |
| : a. This list does not mean that only these nuclides are to be considered. Other peaks that are identifiable, which may be related to plant operations, together with those of the above nuclides, shall also be analyzed and reported inthe Annual Radiological Environmental Operating Report.
| |
| : b. Required detection capabilities for thermoluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13 (Rev. 1).
| |
| : c. The LLD is defined, for purposes of these controls, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.
| |
| For a particular measurement system (which may include radiochemical separation):
| |
| LLD = 4.66 Sb E
| |
| * V
| |
| * 2.22
| |
| * Y
| |
| * exp (-%At)
| |
| Where:
| |
| LLD is the "a priori" lower limit of detection as defined above, as picocuries per unit mass or volume.
| |
| Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume, 2.22 is the number of disintegrations per minute per picocurie, Y is the fractional radiochemical yield (when applicable),
| |
| X is the radioactive decay constant for the particular radionuclide and At for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting.
| |
| Typical values of E, V, Y and At should be used in the calculation.
| |
| It should be recognized that the LLD is defined as an "a priori" (before the fact) limit representing the capability of a measurement system and not as an "a posteriori" (after the fact) limit for a particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidable small samples sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report.
