Radiological Effluent Release Report for 2001

[Including Annual Radiological Impact on Man]

1.0 INTRODUCTION

Tables 1 through 3 list the recorded radioactive liquid and gaseous effluents and solid waste for the year, with data summarized on a quarterly basis for both liquids and gases. Table 4A summarizes released the estimated radiological dose commitments from all radioactive liquid and gaseous effluents I. Also included on during the year 2001 in response to the ALARA objectives of 10CFR50, Appendix boundary Table 4A is the estimate of direct dose from fixed station sources along the limiting west site speed, wind line. Tables 5A through 6H report the cumulative joint frequency distributions of wind direction, and atmospheric stability for the 12-month period, January to December 2001. Radioactive effluents reported in Tables 1 and 2 were used to determine the resulting doses for 2001.

As required by ODCM Section 10.1, dose commitments resulting from the release of radioactive the materials in liquids and gases during the reporting period were estimated in accordance with dose "Vermont Yankee Nuclear Power Station Off-Site Dose Calculation Manual" (ODCM). These II" analysis estimates were made using a "Method II" analysis as described in the ODCM. A "Method incorporates the methodology of Regulatory Guide 1.109 (Reference 3) and actual measured meteorological data recorded during the reporting period.

radiation As required by ODCM Section 10.1, this report shall also include an assessment of the activities inside doses from radioactive effluents to member(s) of the public due to allowed recreational permitted was the site boundary during the year. For this reporting period, the only recreational activity of employee access to a boat launching ramp adjacent to the intake structure. The assessment recreational activities is described in Section 3.6.

Assessment of radiation doses (including direct radiation) to the likely most exposed real with member(s) of the public for the calendar year for the purposes of demonstrating conformance are also 40CFR190, "Environmental Radiation Protection Standards for Nuclear Power Operations,"

"Total Dose," have required to be included in this report if the conditions indicated in ODCM 3/4.6, under been exceeded during the year. Since the conditions indicated in the action statement assessments are ODCM 3/4.6 were not entered into during the year, no additional radiation dose from plant required. However, Table 4B does provide the combination of doses and dose commitments as a demonstration of effluents and direct radiation sources for the limiting member of the public off-site compliance with the dose standards of 40CFRI 90.

Part All calculated dose estimates for this reporting period are below the dose criteria of IOCFR 50, Appendix I, and 40CFR190.

Appendices B through H indicate the status of reportable items per the requirements of ODCM Section 10.1.

2.0 METEOROLOGICAL DATA Meteorological data was collected during this reporting period from the site's 300-foot met tower located approximately 2,200 feet northwest of the reactor building, and about 1,400 feet from the plant stack. The 300-foot tower is approximately the same height as the primary plant stack (94 meters) and is designed to meet the requirements of Regulatory Guide 1.23 for meteorological monitoring.

X/Q and D/Q values were derived for all receptor points from the site meteorological record for each quarter using a straight-line airflow model. All dispersion factors have been calculated employing appropriate source configuration considerations, as described in Regulatory Guide 1.111 (Reference 1).

A source depletion model as described in "Meteorology and Atomic Energy - 1968" (Reference 2) was used to generate deposition factors, assuming a constant deposition velocity of 0.01 mrsec for all stack (elevated) releases. Changes in terrain elevations in the site environment were also factored into the meteorological models as appropriate.

Table 4C lists the distances from the plant stack to the nearest site boundary, resident, and milk animal in each of the 16 principle compass directions as determined during the 2001 land use census.

These locations were used in the calculation of atmospheric dispersion factors.

3.0 DOSE ASSESSMENT 3.1 Doses From Liquid Effluents ODCM 3/4.2.2 limits total body (1.5 mrem per quarter, and 3 mrem per year) and organ doses (5 mrem per quarter, and 10 mrem per year) from liquid effluents to a member of the public to those specified in 10CFR Part 50, Appendix I. By implementing the requirements of 10CFR Part 50, be Appendix I, ODCM 3/4.2.2 assures that the release of radioactive material in liquid effluents will kept "as low as is reasonably achievable."

For periods in which liquid waste discharges actually occur, the exposure pathways that could of exist are fish, direct exposure from river shoreline sedimentation, milk and meat via animal ingestion irrigation with water the Connecticut River water, and meat, milk and vegetable pathways via crop do not withdrawn from the Connecticut River. The drinking water and aquatic invertebrate pathways exist down river of the Vermont Yankee plant.

no There were no recorded liquid radwaste discharges during the report period, and therefore, dose impact.

3.2 Doses From Noble Gases beta air ODCM 3/4.3.2 limits the gamma air dose (5 mrad per quarter, and 10 mrad per year) and from (10 mrad per quarter, and 20 mrad per year) dose from noble gases released in gaseous effluents I. By the site to areas at and beyond the site boundary to those specified in 10CFR Part 50, Appendix assures that the releases implementing the requirements of 10CFR Part 50, Appendix I, ODCM 3/4.3.2 achievable."

of radioactive noble gases in gaseous effluents will be kept "as low as is reasonably at the Dose estimates due to the release of noble gases to the atmosphere are typically calculated point of highest site boundary, nearest resident in each of the sixteen principal compass directions, the of the milk animal locations off-site ground level air concentration of radioactive materials, and for each located within five miles of the plant.

3.3 Doses From Iodine-131, Iodine-133, Tritium, and Radionuclides in Particulate Form With Half-Lives Greater Than 8 Days ODCM 3/4.3.3 limits the organ dose to a member of the public from iodine-131, iodine-133, called iodines tritium and radionuclides in particulate form with half-lives greater than 8 days (hereafter site boundary to and particulates) in gaseous effluents released from the site to areas at and beyond the mrem per year). By those specified in 10CFR Part 50, Appendix 1 (7.5 mrem per quarter, and 15 that the releases implementing the requirements of IOCFR Part 50, Appendix I, ODCM 3/4.3.3 assures achievable."

to the Exposure pathways that could exist as a result of the release of iodines and particulates surface, inhalation, and atmosphere include external irradiation from activity deposited onto the ground boundary and nearest ingestion of vegetables, meat and milk. Dose estimates were made at the site animal locations within resident in each of the sixteen principal compass directions, as well as all milk were identified by the most five miles of the plant. The nearest resident and milk animals in each sector 4C). Conservatively, a recent Annual Land Use Census as required by ODCM 3/4.5.2 (see Table vegetable garden was assumed to exist at each milk animal and nearest resident location. Furthermore, data category is not part of the meat pathway was assumed to exist at each milk cow location since this ground level air the annual land use census. Doses were also calculated at the point of maximum assumption that the concentration of radioactive materials in gaseous effluents and included the for an individual with a 100 inhalation, vegetable garden, and ground plane exposure pathways exist percent occupancy factor.

the second and It is assumed that milk and meat animals are free to graze on open pasture during since most of the milk third quarters with no supplemental feeding. This assumption is conservative year with only limited animals inventoried in the site vicinity are fed stored feed throughout the entire 50 percent of the iodine grazing allowed during the growing season. It has also been assumed that only deposited from gaseous effluent is in elemental form (12) and is available for uptake (see p. 26, to receive only stored Reference 3). During the first and fourth quarters, the milk animals are assumed in Table 4D. Table 4E feed. Usage factors for gaseous effluents are listed by age group and pathway provides other dose model parameter assumptions used in the dose assessments.

from all pathways at The resultant organ doses were determined after adding the contributions kidney, thyroid, lung and each location. Doses were calculated for the whole body, GI-tract, bone, liver, quarterly and annual organ skin for adults, teenagers, children and infants. The maximum estimated receptor locations are doses to any age group due to iodines and particulates at any of the off-site Part 50, Appendix I dose reported in Table 4A. These estimated organ doses are well below the 10CFR criteria of ODCM 3/4.3.3.

3.4 Whole-Body Doses in Unrestricted Areas From Direct Radiation the station is due to The major source of dose, consisting of direct radiation and skyshine, from Building on the site, and N-16 decay in the Turbine Building. Because of the orientation of the Turbine sectors (SSW to NNW) the shielding effects of the adjacent Reactor Building, only the seven westerly see any significant direct radiation.

made along Prior to 2001, historical High Pressure Ionization Chamber (HPIC) measurements plant's steam cycle and the plant property line were used to estimate the direct radiation from the rate with different plant carryover of N- 16. Past correlation's of measurements of site boundary dose predicted integrated dose from power levels (from shutdown to 100 percent), resulted in an algorithm of over periods of interest. This direct radiation based on recorded gross megawatts generated by the plant during the first calendar original method as documented in the ODCM (Revision 29) was applicable refueling outage, the quarter of 2001 up to the refueling outage with began April 27. During the 2001 system as a precursor to also station implemented Noble Metal Chemistry (NMC) in the reactor coolant the reactor coolant utilizing Hydrogen Water Chemistry to help counter stress corrosion fatigue of the expected carryover of N system. As a secondary consequence of this change in coolant chemistry, 4

power 16 in the steam cycle could no longer be expected to follows a simple correlation with gross along output as originally measured. Following the 2001 plant outage, a new set of HPIC measurements dose the west site boundary were made over a six week period, with the results correlated with in-plant period. A rates measured by the four Main Steam Line Radiation Monitors (MSLRM) over the same flow new correlation method was derived that allowed changes in the N-16 carryover in the main steam output.

to be directly related to changes in the site boundary dose without consideration of gross power cycle used this Direct doses at the maximum site boundary location from radiation sources in the steam situated along new method to account for accumulated doses on the site boundary and nearest resident 2001).

this same boundary line following return to power from the refueling outage (May, are The other fixed sources of dose, including direct radiation and skyshine, to the site boundary Storage Pad from low level radioactive waste stored in the North Warehouse, the Low Level Waste is based on Facility, and old turbine rotors and casings in the turbine storage facility. The annual dose restrictive site dose rate measurements in these three storage facilities and determined at the same most boundary dose location as that for N- 16 shine from the Turbine Building.

site The estimated direct radiation dose from all major sources combined for the most limiting occupancy boundary location is listed on Table 4A. These site boundary doses assume a 100 percent factor, and take no credit for the shielding effect of any residential structure.

Table 4B lists the combination of direct radiation and effluent release doses at the limiting contained in nearest residence for the purpose of demonstrating compliance with the dose standards is equal to 40CFR190. For direct radiation, no credit for actual occupancy time is taken (i.e., occupancy 100%).

3.5 Doses From On-Site Disposal of Septic Waste and Cooling Tower Silt of septage Off-Site Dose Calculation Manual, Appendices B and F, require that all applications to ensure the dose to and the cooling tower silt within the approved designated disposal areas be limited be maintained at less a maximally-exposed individual during the period of Vermont Yankee site control Yankee than 1 mrem/year to the whole body and any organ. After the period associated with Vermont at less than 5 mrem/year.

operational control, the dose to the inadvertent intruder is to be maintained given in Appendix The projected dose from on-site disposals of septic waste and the cooling tower silt is J of this report.

3.6 On-Site Recreational Activities ramp During 2001, no access for employees, their families and guests to the boat launching activities were located on-site just north of the intake structure was permitted. As such, no recreational members of the permitted on-site during the report period and, therefore, no associated dose impact to public.

C. Liquids 3/4.2.1 Sum of the fractions of ECL excluding noble gases (IOCFR20, Appendix B, Table 2, Column 2): < .OE+01 3/4.2.1 Total noble gas concentration: < 2E-04 [tCi/cc

3. AVERAGE ENERGY Provided below are the average energy (E) of the radionuclide mixture in releases of fission and activation gases, if applicable.

a. Average gamma energy: Not Applicable

b. Average beta energy: Not Applicable

4. MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY Provided below are the methods used to measure or approximate the total radioactivity in effluents and the methods used to determine radionuclide composition.

a. Fission and Activation Gases Continuous stack monitors monitor the gross Noble Gas radioactivity released from the plant stack. Because release rates are normally below the detection limit of these monitors, periodic grab samples are taken and analyzed for the gaseous isotopes present. These are used to calculate the individual isotopic releases indicated in Table 1B and the totals of Table IA. The error involved in these steps may be approximately +/-23 percent.

b. lodines Continuous isokinetic samples are drawn from the plant stack through a particulate filter and charcoal cartridge. The filters and cartridges are normally removed weekly and are analyzed for Iodine-131, 132, 133, 134, and 135. The error involved in these steps may be approximately +/-18 percent.

A-2

c. Particulates The particulate filters described in b. above are also counted for particulate radioactivity. The error involved in this sample is also approximately +/-18 percent.

d. Tritium ODCM Table 4.3.1 requires as a minimum that grab samples from the plant stack be taken monthly and analyzed for tritium. The stack sampling design included a cold trap collection device for this sample collection. The error involved in this sample is approximately +/-15 percent.

e. Waste Oil Prior to issuing the permit to burn a drum of radioactively contaminated waste oil, one liter of the oil is analyzed by gamma spectroscopy to determine concentrations of radionuclides that meet or exceed the LLD for all of the liquid phase radionuclides listed in ODCM Table 4.2.1.

Monthly, samples from drums that were issued bum permits are sent to the contracted laboratory for compositing and analysis. The lab analyzes for tritium, alpha, Fe-55, Sr-89, and Sr-90 on the composite sample.

The error involved in this sample is approximately +/-15 percent.

f. Liquid Effluents If radioactive liquid effluents are to be released from the facility, they are continuously monitored. Measurements are also required on a representative sample of each batch of radioactive liquid effluents released. For each batch, station records are retained of the total activity (mCi) released, concentration (pCi/ml) of gross radioactivity, volume (liters), and approximate total quantity of water (liters) used to dilute the liquid effluent prior to release to the Connecticut River.

Each batch of radioactive liquid effluents to be released is analyzed for gross gamma and gamma isotopic radioactivity. A monthly proportional composite sample, comprising an aliquot of each batch released during a month, is analyzed for tritium and gross alpha radioactivity. A quarterly proportional composite sample, comprising an aliquot of each batch released during a quarter, is analyzed for Sr-89, Sr-90, and Fe-55.

A-3

5. BATCH RELEASES

a. Liqui There were no routine liquid batch releases during the reporting period.

b. Gaseous Waste oil was burned during the first quarter and was considered to be a continuous release.

The gaseous releases from burning waste oil are treated as either batch or continuous releases based on the total hours of burning in a calendar quarter.

6. ABNORMAL RELEASES

a. Liqui There were no nonroutine liquid releases during the reporting period.

b. Gaseous There were no nonroutine gaseous releases (measured) during the reporting period.

A-4

Specific key elements of the program are outlined and described below with a basic philosophy or approach provided.

I. Procedures

a. Controls for waste activities are written in the form of administrative and operational procedures. Procedures are to be considered as management directives and are expected to be followed.

b. Written procedures shall contain sufficient detail to ensure satisfactory compliance with the work effort, but need not delineate basic skills normally possessed by qualified personnel as determined and described in the Training and Qualification Section of this procedure. Training prerequisites are outlined in AP 0504, Shipment of Radioactive Material.

c. Vendor technical information shall be used as reference material in the preparation of procedures and should be used as guidance in conjunction with specific tasks, if appropriate.

2. Training and Qualification

a. Performance-based, accredited training programs are approved, in place and functional for Technical Staff and Managers, Supervisor Development, Operations, Maintenance and Radiation Protection Technicians.

Program performance monitoring and control of content is accomplished through direct interaction between department supervision and management, the Technical Services Superintendent and the Training Department.

PP 7504 Rev. 3 Page 6 of 10

b. Job posting and individual position descriptions establish the minimum qualifications.

General knowledge and basic skill levels are demonstrated through testing ofjob applicants.

c. The RWS, integral with the Training Department, maintains and ensures the assignment of qualified personnel to perform duties in support of program objectives. This is accomplished through personnel observation, interaction and varying degrees of direct supervision. Training prerequisites are outlined in AP 0504, Shipment of Radioactive Material.

d. Contracted services, whether integrated with staff personnel or assigned specific tasks,

. . ............................. a if d t . e th esa quai ti a ti iig i- ............

work activities.

3. Performance Indicators Performance indicators are an important element of any program which enable the program owner to conduct timely assessments of the effectiveness of a programn The RWS shall monitor the effectiveness of the program efforts by generating and trending the following performance indicators, as a minimum:

• Monthly and annual radwaste amounts generated for burial in cubic feet and cubic meters.

Monthly radwaste generated prior to processing; accrual cost and cubic feet or pounds generated.

4. General Implementation Implementation of this program is generally controlled by approved procedures. This section does not supersede or eliminate the need for specific procedures when appropriate. The topics contained in this section illustrate management approval and direction for those areas identified.

a. Solidification Vermont Yankee Nuclear Power Corporation does not routinely solidify liquid waste. If the use of solidification to dispose of any liquid waste is required, it will be done by an outside vendor under the vendor's PCP. The vendor PCP will be reviewed and approved by the Plant Health Physicist, the Radiation Protection Manager, PORC, Plant Manager and VP of Operations prior to implementation. This review is to identify that there is sufficient supporting documentation of the vendor's PCP to give assurance that the final product will meet all requirements for transport and burial, and that sufficient procedural controls exist to assure safe operations.

PP 7504 Rev. 3 Page 7 of 10

b. Cartridge Filter Elements Low activity cartridge filter elements (<200 mR/hr @ 30cm) will be air dried (-24hr or as determined by the Radwaste Supervisor) and handled as dry active waste. Filters determined to be above the dose limitations per 49 CFR,, will be placed in casks. The liner shall be dewatered by the RDS-1 000 System or a similar approved system and then shipped for disposal.

c. Resins Normal operations produce radioactive waste in the form of depleted resins. These resins are processed in the burial container using a rapid dewatering system (RDS-1000) fa t e by C N Sy eifs I " [OP-2153] ........ ......... I.............................

The system has been tested, by Chem-Nuclear, for certification in meeting the Barnwell Site Criteria and disposal requirement for free standing liquid. These tests are described in Chem-Nuclear's Topical Report on the RDS-1000 Radioactive Waste Dewatering System. In addition, to comply with the statement, "Any liquids present in waste packages shall be non-corrosive with respect to the container," Vermont Yankee tested the pH of various resin mixtures used by the plant in solution with water. The range was found to be 4.2 - 8.4. A solution is not considered corrosive if the pH is greater than 4.0 and less than 10.0.

A resin sample is taken from each liner prior to shipment. The sample is counted to determine the activity and waste classification. Class A resins that exceed 1.0 MCi/cc of isotopes with greater than 5 year half-lives and all Class B and C resins will be disposed of in an approved High Integrity Container (HIC).

Vendor supplied or temporary methods of processing resins may be used in lieu of the above process provided that the vendor or temporary process meets the requirements of quality described above and does not conflict with accepted burial criteria or safety requirements. Such methods will be reviewed and approved by the personnel stated in 4.a prior to implementation.

d. Filter Liners During refueling outages and normal operation, liquid radwaste processing may require use of a decanting filter on the condensate phase separators. A floating suction is used to decant the water and resin into a filter liner. Filtered water is pumped from the liner.

The liner is dewatered in accordance with OP 2153 (M0OOD9409-03) such that the burial site criterion for free-standing water is met. A resin sample is taken from the liner and analyzed to determine the activity and waste classification.

PP 7504 Rev. 3 Page 8 of 10

e. Dry Active Waste (DAW)

DAW is compacted, as practical, or shipped to a vendor that sorts the material for processing or recycling. All DAW is examined before being compacted or shipped. Any liquids or items found that would compromise the integrity of the package are removed and separated as specified by procedure [OP 2512]. DAW which includes compactable, incinerable and metal materials are segregated in the plant and transported to the applicable sealand container, then shipped to the appropriate/cost effective off-site processor. If deemed practical, the DAW will be surveyed and free-released onsite, if possible. Containers used for DAW shipments meet the criteria of 49 CFR 173.425a. or

b. "No leakage of radioactive material," as specified in 49 CFR 173.425.b.1 will be met provided that no radioactive materials in quantities equal to or exceeding those specified in 49 CFR 173.443 are detected on the external surfaces of the package at any time during shipment.

f. Chelating Agents In order to comply with 10 CFR 20 Appendix G, chelating agents are controlled by the plant chemistry department using procedure AP 7602.

g. Explosive Waste No waste capable of detonation or of explosive decomposition or reaction will be disposed as per 10 CFR 61.56(a)(4). Refer to MSDS via AP 7602.

h. Toxic Waste No waste capable of generating toxic gases, vapors, or fumes will be disposed as per 10 CFR 61.56(a)(5). Refer to MSDS via AP 7602.

Pvrophoric Waste No waste that is pyrophoric will be disposed as per 10 CFR 61.56(a)(6). Refer to MSDS via AP 7602.

j. High Integrity Containers (HICs)

Vermont Yankee Nuclear Power Plant has contracted with various suppliers of approved HICs. South Carolina has approved PCPs for HICs used by Vermont Yankee. Any HIC Vermont Yankee may choose to use at some future time, will meet all applicable requirements.

Waste Class Determination Along with an approved outside laboratory, Vermont Yankee periodically performs laboratory analysis on all waste streams to determine the activity of radionuclides listed in Tables 1 and 2 of 10 CFR 61. Correlation analysis verifies that the relative concentration of each radionuclide, with respect to the overall activity in a given Vermont Yankee waste stream, remains constant over time. A set of scaling factors is determined which allows the activity of 10 CFR 61 radionuclides to be estimated using the results of gamma spectrometric analysis or direct gamma dose rate measurements.

For resin wastes, analysis is performed on samples of each source of resin comprising the contents of a burial container. Scaling factors are applied to the activity of radionuclides identified by gamma spectrometry analysis to determine the activity of those radionuclides which are not detected in the gamma spectrum.

For DAW, dose rate-to-curie conversion calculations are performed to determine the total activity present in a container. Scaling factors are applied to the container's total curie content to determine the activity of individual radionuclides.

Specific procedures for determining 10 CFR 61 scaling factors are contained in OP 2527, "Sampling and Analysis for Radwaste Classification." Once the activity of each radionuclide in a burial container is estimated, the waste classification is derived using methods required by 10 CFR 61. Specific procedures for waste class determination are contained in AP 0504, "Shipment of Radioactive Material."

I. Mixed Waste No mixed waste will be disposed as per 10 CFR 61.56(a)(8) unless properly treated.

Refer to MSDS via AP 7602.

FINAL CONDITIONS

1. This procedure is retained per AP 6805.

APPENDIX H OFF-SITE DOSE CALCULATION MANUAL Requirement: Technical Specification 6.7.B. 1 requires that licensee initiated changes to the Off Site Dose Calculation Manual (ODCM) be submitted to the Commission in the annual Radioactive Effluent Release Report for the period in which the change(s) was made effective.

Response: During the reporting period, Revision No. 28 was made to the ODCM.

The major changes included in Revision 28 to the ODCM are:

(28.A) Deletion of Frequencies for the River Water Compositor The frequencies suggested for the River Composite Sampler were deleted from note f. of Table 3.5.1.

(28.B) Revision in Method of Calculating Averages Note f. of Table 4.5.1 included a requirement to convert sample results to zero before averaging. This note was deleted since this is not the recommended way to report low level analyses results since it skews averages to lower values. The preferred method is to use the report analysis values for the averaging even for the results that are below LLD. These results are reported in the Annual Radiological Environmental Operating Report.

The above-noted ODCM changes were determined to maintain the level of protection in the calculation of off-site doses resulting from radioactive gaseous and liquid effluents since no changes have been made to either the dose calculation or setpoint methodologies. It is therefore concluded that these revisions will maintain the level of radioactive effluent control required by 10CFR20.1302, 40CFR190, 10CFR50.36a, and Appendix I to 10CFR Part 50, and not adversely impact the accuracy or reliability of effluent dose or setpoint calculations.

Revision 28 of the ODCM was submitted to the Nuclear Regulatory Commission separately but concurrently with this report.

APPENDIX I RADIOACTIVE LIQUID, GASEOUS, AND SOLID WASTE TREATMENT SYSTEMS Requirement: ODCM Section 10.4 requires that licensee initiated major changes to the radioactive waste systems (liquid, gaseous, and solid) be reported to the Commission in the annual Radioactive Effluent Release Report for the period in which the evaluation was reviewed by the Plant Operation Review Committee.

Response: There were no licensee-initiated major changes to the radioactive waste systems during this reporting period.

APPENDIX J ON-SITE DISPOSAL OF SEPTIC/SILT/SOIL WASTE Requirement: Off-Site Dose Calculation Manual, Appendices B and F require that the dose impact due to on-site disposal of septic waste and the cooling tower silt during the reporting year and from previous years be reported to the Nuclear RegulatoryCommission in the annual Radioactive Effluent Report if disposals occur during the reporting year.

VYNPC will report in the Annual Radioactive Effluent Release Report a list of the radionuclides present and the total radioactivity associated with the on-site disposal activities at Vermont Yankee.

Response: There was one on-site disposal of septic waste and one on-site disposal of construction soil during the reporting year. The total volume of the septage spread was approximately 12,000 gallons and the total volume of soil spread was approximately 26.3 M 3 . The total activity spread on the 1.9 acres (southern) on-site disposal field from 2001 spreadings and from previous years was as follows:

Activity from 2001 and Activity from Activity Spread in 2001 Past Disposals Decayed to 2001 Nuclide Lc0) (Ci)

Mn-54 0.OOE+00 1.83E-07 Co-60 7.75E-06 1.99E-05 Zn-65 2.07E-06 2.13E-06 Cs-137 2.96E-06 6.75E-05 Ce- 141 1.69E-07 1.69E-07 The maximum organ (or whole body) incremental dose from material spread in 2001 was estimated to be 2.49E-02 mrem/yr. The maximum organ dose from all past spreading operations, including the material spread in 2001, totaled 1.20E-01 mrem/yr. These calculated values are within the I mrem/yr limit applied during the period of operational control of the site. The projected hypothetical dose for the period following the loss of operational control of the site area due to all spreading operations to-date is 1.70E-01 mrem/yr versus a 5 mrem/yr dose limit.

TABLE 4.3.1 NOTATION

a. See footnote a. of Table 4.2.1.

b. Samples shall be changed at least once per 7 days and analyses shall be completed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after removal from samplers.

When samples collected for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> are analyzed, the corresponding LLDs may be increased by a factor of 10. This requirement to sample at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for 7 days applies only if: (1) analysis shows that the dose equivalent 1-131 concentration in the primary coolant has increased more than a factor of 3 and the resultant concentration is at least 1 x 10-1 RzCi/ml; and (2) the noble gas monitor shows that effluent activity has increased more than a factor of 3.

c. Sampling and analyses shall also be performed following shutdown, startup, or a thermal power change exceeding 25% of rated thermal power per hour unless: (a) analysis shows that the dose equivalent 1-131 concentration in the primary coolant has not increased more than a factor of 3 and the resultant concentration is at least 1 x 10-1 jlCi/ml; and (2) the noble gas monitor shows that effluent activity has not increased more than a factor of 3.

d. The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides: Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135 and Xe-138 for gaseous emissions, and Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce 141 and Ce-144 for particulate emissions. This list does not mean that only these nuclides are to be detected and reported. Other peaks which are measurable and identifiable, together with the above nuclides, shall also be identified and reported.

Nuclides which are below LLD for the analyses should not be reported as being present at the LLD level for that nuclide, but as "not detected". When unusual circumstances result in LLDs higher than required, the reasons shall be documented in the Radioactive Effluent Release Report.

e. The ratio of the sample flow rate to the sampled stream flow rate shall be known for the time period covered by each dose or dose rate calculation made in accordance with Controls 3.3.1, 3.3.2, and 3.3.3.

f. The gaseous waste sampling and analysis program does not explicitly require sampling and analysis at a specified LLD to determine the 1-133 release. Estimates of 1-133 releases shall be determined by counting the weekly charcoal sample for 1-133 (as well as 1-131) and assume a constant release rate for the release period.

g. Lower Limit of Detection (LLD) applies only to particulate form radionuclides identified in Table Notation d. above.

TABLE 3.5.1 NOTATION a Specific parameters of distance and direction sector from the centerline of the reactor and additional descriptions where pertinent, shall be provided for each and every sample location in Table 3.5.1 in a table and figure(s) in the ODCM (Section 7). Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, every reasonable effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report pursuant to ODCM Section 10.2. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances, suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the radiological environmental monitoring program. In lieu of a Licensee Event Report and pursuant to ODCM Section 10.1, identify the cause of the unavailability of samples for that pathway and identify the new location(s) for obtaining replacement samples in the next Radioactive Effluent Release Report and also include in the report a revised figure(s) and table for the ODCM reflecting the new location(s).

b One or more instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. For the purposes of this table, a Thermoluminescent Dosimeter (TLD) is considered to be one phosphor; two or more phosphors in a packet are considered as two or more dosimeters. Film badges shall not be used as dosimeters for measuring direct radiation. The 40 stations is not an absolute number. The frequency of analysis or readout for TLD systems will depend upon the characteristics of the specific system used and should be selected to obtain optimum dose information with minimal fading.

c Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more after sampling to allow for radon and thoron daughter decay. If gross beta activity in air particulate samples is greater than ten times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

d Gamma. isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.

e The "upstream sample" shall be taken at a distance beyond significant influence of the discharge. The "downstream" sample shall be taken in an area beyond but near the mixing zone.

f Composite sample aliquots shall be collected at time intervals that are very short relative to the compositing period in order to assure obtaining a representative sample.

g Each meteorological sector shall have an established "inner" and an "outer" monitoring location based on ease of recovery (i.e., response time) and year-round accessibility.

h Sample collection will be performed weekly whenever the main plant stack effluent release rate of I 131, as determined by the sampling and analysis program of Table 4.3.1, is equal to or greater than 1 x 10-1 uCi/sec. Sample collection will revert back to semimonthly no sooner than at least two weeks after the plant stack effluent release rate of 1-131 falls and remains below 1 x 10-1 uCi/sec.

(b) Parent only.

(c) If the measured concentration minus the 5 sigma counting statistics is found to exceed the specified LLD, the sample does not have to be analyzed to meet the specified LLD.

(d) This list does not mean that only these nuclides are to be considered. Other peaks that are identifiable, together with those of the listed nuclides, shall also be analyzed and reported in the Annual Radiological Environmental Operating Report pursuant to Technical Specification 6.6.E and ODCM Section 10.2.

(e) The Ba-140 LLD and concentration can be determined by the analysis of its short-lived daughter product La-140 subsequent to an 8 day period following collection. The calculation shall be predicted on the normal ingrowth equations for a parent-daughter situation and the assumption that any unsupported La-140 in the sample would have decayed to an insignificant amount (at least 3.6 percent of its original value). The ingrowth equations will assume that the supported La-140 activity at the time of the collection is zero.

(f) Nuclides which are below the LLD for the analyses should not be reported as being present at the ILD.
