1.0 INTRODUCTION

Grand Gulf Nuclear Station (GGNS) is a nuclear site consisting of one General Electric BWR-6 boiling water reactor with a rated power level of 4408 MWt. The station achieved 193.4 effective full-power days of operation in 2020.

Airborne discharges at GGNS are considered ground-level releases. All liquid and airborne discharges to the environment were analyzed in accordance with Offsite Dose Calculation Manual (ODCM) requirements. All effluent releases were within the concentration and total release limits specified by the ODCM. Projected offsite doses were within the dose limits specified by the ODCM.

This Annual Radioactive Effluent Release Report (ARERR) for the period January 1 through December 31, 2020 is submitted in accordance with Technical Specifications Section 5.6.3 of GGNS License Number NPF-29. The monitoring of radioactive effluents is referenced in ODCM Appendix A, Sections 6.11 and 6.12.

2.0 SUPPLEMENTAL INFORMATION 2.1 Regulatory Limits The ODCM contains the limits to which GGNS must adhere. Because of the "as low as reasonably achievable" (ALARA) philosophy at GGNS, actions are taken to reduce the amount of radiation released to the environment. Liquid and gaseous release data show that the dose from GGNS is considerably below the ODCM limits. This data reveals that the radioactive effluents have an overall minimal dose contribution to the surrounding environment. The following are the limits required by the ODCM:

1. Fission and Activation Gases

a. Noble gas dose rate due to radioactive materials released in gaseous effluents to areas at and beyond the site boundary shall be limited to the following:

500 mrem/year to the total body

3000 mrem/year to the skin

b. Noble gas air dose due to noble gases released in gaseous effluents to areas at and beyond the site boundary shall be limited to the following:

1) Quarterly

5 mrad gamma

10 mrad beta

2) Yearly

10 mrad gamma

20 mrad beta

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 4 of 21 Annual Radioactive Effluent Release Report

2. Iodine, Tritium, and Particulate Radionuclides

a. The dose rate for Iodine-131, Iodine-133, tritium, and all radionuclides in particulate form with half-lives greater than 8 days in gaseous effluents released to areas at and beyond the site boundary shall be limited to the following:

1500 mrem/year to any organ

b. 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 to areas at and beyond the site boundary shall be limited to the following:

1) Quarterly

7.5 mrem to any organ

2) Yearly

15 mrem to any organ

3. Liquid Effluents Dose

a. The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released to unrestricted areas shall be limited to the following:

1) Quarterly

1.5 mrem to the total body

5 mrem to any organ

2) Yearly

3 mrem to the total body

10 mrem to any organ

4. Total Dose (40 CFR 190)

a. 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 the following:

25 mrem to the total body or any organ except the thyroid

75 mrem to the thyroid

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 5 of 21 Annual Radioactive Effluent Release Report 2.2 Maximum Permissible Concentrations

1. Fission and Activation Gases, Iodine, and Particulates with Half Lives > 8 Days For gaseous effluents, maximum permissible concentrations are not directly used in release rate calculations since the applicable limits are expressed in terms of dose rate at the site boundary.

2. Liquid Effluents The concentration of radioactive material released in liquid effluents to UNRESTRICTED AREAS shall be limited to ten times the concentration specified in 10 CFR 20, Appendix B, Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the total concentration released shall be limited to 2.0E-4 microcuries/ml total activity.

2.3 Average Energy

1. Average Energy determination is not applicable to GGNS. The ODCM limits the instantaneous dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin. The average beta and gamma energies as described in Regulatory Guide 1.21, Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants, may be used to calculate doses in lieu of more sophisticated software.

The GGNS radioactive effluent programs employs the methodologies presented in U.S. NRC 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 NUREG-0133, Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, October 1978. Therefore, average energies are not required for GGNS.

2.4 Measurements and Approximations of Total Radioactivity

1. Gaseous Effluents

a. Fission and Activation Gas Gas samples are collected monthly from gaseous release points and are counted on a high purity germanium (HPGe) detector for principal gamma emitters. The radionuclides detected are used for release rate calculations. During the period between grab samples, the amount of radioactivity released is based on the effluent radiation monitor readings, which are assigned a scaling factor based on the last isotopic analysis.

The scaling factor, along with hourly effluent monitor values and flow rates, are entered into a laboratory computer where the release rates for individual radionuclides are calculated and stored. If no radionuclides are detected in the grab sample, the scaling factor defaults to the monitor response from a historical default mixture of fission gases.

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 6 of 21 Annual Radioactive Effluent Release Report The Technical Specification release points listed below are continuously monitored.

1) Radwaste Building Vent (includes Offgas)

2) Containment Building Vent

3) Fuel Handling Area Vent

4) Turbine Building Vent

5) Turbine Building Occasional Release Point (when releasing)

b. Radioiodine Iodine is continuously collected on a TEDA charcoal filter via an isokinetic sampling assembly from each release point. Filters are normally exchanged once per week and then analyzed on a HPGe detector. The flow rates for each release point are averaged over the duration of the sampling period and used in conjunction with the specific radionuclide concentrations measured to calculate the total activity released during the sampling period.

c. Particulate (Half-Life > 8 Days)

Particulates are continuously collected on a glass-fiber filter via an isokinetic sampling assembly from each release point. Filters are normally exchanged once per week and then analyzed on a HPGe detector. The flow rates for each release point are averaged over the duration of the sampling period and used in conjunction with the specific isotopic concentrations measured to calculate the total activity released during the sampling period.

d. Tritium Tritium is collected monthly by passing a known volume of the sample stream from each release point through a molecular sieve filter. The collected sample is distilled and analyzed by liquid scintillation. The tritium released is calculated for each release point from the measured tritium concentration, the volume of the sample, the tritium collection efficiency, and the stack exhaust flow rate.

e. Gross Alpha Particulate filters from weekly samples are retained and analyzed monthly for gross alpha radioactivity using a gas proportional detector.

f. Hard-to-Detect Radionuclides (Sr-89 and Sr-90)

Particulate filters from weekly samples are retained and shipped quarterly to a qualified contract lab for Strontium-89/90 analysis. This analysis involves chemical separation and subsequent measurement using a gas proportional detector.

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 7 of 21 Annual Radioactive Effluent Release Report

g. Carbon-14 Carbon-14 activity of 9.72 Curies released this year in gaseous form was obtained by estimation using EPRI spreadsheet BWR Source Term Calculation (MAL-1)_r1 and the information in NEAD-NS-11-0060-REV1-EC42519 and adjusted by 193.4 full power production days. Carbon-14 activity reported in the tables of this report are based on a constant release rate.

2. Liquid Effluents

a. Each tank of liquid radwaste is sampled and analyzed for principal gamma emitters prior to release. Each sample tank is recirculated for enough time prior to sampling to ensure that a representative sample is obtained.

Samples are then analyzed on a HPGe detector and liquid release permits are generated based upon the values obtained from the isotopic analysis and the most recent values for tritium, gross alpha, and hard-to-detect radionuclides (Fe-55, Sr-89, and Sr-90). An aliquot based on release volume is saved and added to composite containers. The concentrations of composited radionuclides and the volumes of the releases associated with these composites establish the proportional relationships that are then utilized for calculating the total activity released for these radionuclides.

b. Tritium analysis is performed monthly on the liquid composite sample, where the sample is distilled and analyzed with a liquid scintillation detector.

c. Gross alpha analysis is performed monthly on the liquid composite sample using a gas proportional detector.

d. Hard-to-Detect radionuclides Fe-55, Sr-89 and Sr-90 analyses are performed quarterly by a qualified contract lab on the liquid composite sample. Following chemical separations, Fe-55 is analyzed with a low-energy photon detector, and Sr-80/90 is analyzed using a gas proportional detector.

3. Estimated Total Error Present Estimates of measurement and analytical error for gaseous and liquid effluents are calculated as follows:

= [(1 )2 + (2 )2 + ( )2 ]

Where: ET = total percent error E1 ... En = percent error due to calibration standards, laboratory analysis, instruments, sample flow, etc.

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 8 of 21 Annual Radioactive Effluent Release Report 2.5 Batch Releases

Liquid Quarter Quarter Quarter Quarter Time periods in minutes Year 1 2 3 4 Number of Releases 44 57 24 39 164 Total Release Time 1.51E+04 1.88E+04 7.90E+03 1.42E+04 5.61E+04 Maximum Release Time 4.59E+02 4.15E+02 4.05E+02 9.75E+02 9.75E+02 Average Release Time 3.44E+02 3.30E+02 3.29E+02 3.64E+02 3.42E+02 Minimum Release Time 2.55E+02 2.77E+02 2.87E+02 6.00E+00 6.00E+00 Average Dilution Water 7.26E+03 6.77E+03 7.76E+03 4.34E+03 6.40E+03 Flow (GPM)

a. The unusually low minimum release time for fourth quarter resulted from a discharge that terminated shortly after starting due to alarm of the liquid effluent radiation monitor. This event is documented in CR-GGN-2020-11892.

2. Gaseous

a. No batch releases occurred during the report period.

2.6 Continuous Releases

1. Liquid

a. Number of continuous releases: None

2. Gaseous

a. Continuous sampling is performed on the continuous release points:

1) Radwaste Building Vent

2) Containment Building Vent

3) Fuel Handling Area Vent

4) Turbine Building Vent

5) Turbine Building Occasional Release Point (when releasing)

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 9 of 21 Annual Radioactive Effluent Release Report 2.7 Abnormal Releases

1. On 1/2/20 a Turbine Building roof hatch was found partially open. The total activity released was estimated using conversative assumptions. The estimated activity was negligible (0.05%) when compared to the total activity of 181 Curies released from all gaseous release points in 2020 and is not included in the totals for activity and dose in this report. This event, including estimated release calculations, is documented in CR-GGN-2020-0013.

2. On 11/30/20 a HPGe detector issue caused incorrect gamma analysis results for a liquid radwaste tank that subsequently resulted in calculated liquid effluent radiation monitor setpoints that were too low for the actual activity of the tank. The radiation monitor alarmed due to high activity six minutes after the tank discharge began and stopped the release. A total of 342 gallons was discharged prior to the automatic isolation. The tank sample was re-analyzed on another HPGe detector and the effluent tracking database was updated for volume, activity, and public dose for the release. This event is documented in CR-GGN-2020-11892.

3. Liquid

a. Number of releases: 1

b. Total activity released: 3.61E-03 Ci

4. Gaseous

a. Number of releases: 1

b. Total activity released: 8.98E-02 Ci 2.8 Non-routine, Planned Discharges

1. None 2.9 Radioactive Waste Treatment System Changes

1. No changes during the report period.

2.10 Land Use Census Changes The Land Use Census was completed in November 2020. There were minor changes to locations of nearest unoccupied residences, but these resulted in no changes or modifications affecting receptors, receptor locations or routes of exposure since the previous Land Use Census.

PLANT: Grand Gulf Nuclear Station YEAR: 2020 Page 10 of 21 Annual Radioactive Effluent Release Report 2.11 Effluent Monitor Instrument Inoperability

1. On 3/25/20 the Circulating Water Low Blowdown Flow Interlock had been bypassed and not restored within 30 days due to an extended Plant Service Water system maintenance period during Refuel Outage 22. The interlock was restored following systems restoration prior to plant startup. This condition is documented in CR-GGN-2020-4076.

2. On 10/2/20 the Radwaste Building Ventilation Effluent System Flow Rate Monitor was not restored within 30 days following removal from service for monitor calibration. The delay was due to monitor repair issues and need for an Engineering Change to approve a replacement controller. An alternate method of determining system flow rate was implemented during the period of inoperability. The monitor was repaired and returned to service in April 2021.

This condition is documented in CR-GGN-2020-10264 and CR-GGN-2020-10303.

2.12 Offsite Dose Calculation Manual Changes

1. The ODCM was revised in February 2020 to Revision 42. This revision:

a. Added notations to Table 6.3.10-1 (Radioactive Gaseous Effluent Monitoring Instrumentation) to clarify monitoring system requirements for Turbine Building Occasional Release Point during modes 4 and 5. The notations were inadvertently deleted in a previous revision.

b. Revised Table 6.12.1-1 (Operational Radiological Environmental Monitoring Program) to correct table notation for Fish Pathway samples and changed number of samples/locations for Airborne Radioiodine and Particulates to align with Table 3.0-1 (Air Sampler Collection Sites).

c. Removed previous revision notations and updated all pages to current revision number.

2. A copy of the revised ODCM is submitted concurrently with this report.

2.13 Process Control Program (PCP) Changes

1. None 2.14 NON-REMP Groundwater Monitoring Results (NEI 07-07)

1. Ground water samples were taken in support of the Groundwater Protection Initiative. These samples are not part of the Radiological Environmental Monitoring Program. Sample results are included in Attachment 1.

2.15 Sewage Disposal Summary

1. There were no sewage disposals during the report period.

2.16 Errata/Corrections to Previous ARERRs

Observation Wells (OW), and Sump Wells (SW). Samples were analyzed for Tritium and selected samples were analyzed for gamma and/or hard-to-detect (HTD) radionuclides (Gross Alpha, Iron-55, Nickel-63, Strontium-89 and Strontium-90). Analyses are to the Lower Level of Detection (LLD) values for the GGNS Radiological Environmental Monitoring Program.

No dose to the public is attributed to ground water since wells with results above Minimum Detectable Activity (MDA) are bounded by wells which are less than MDA. Tritium, gamma and/or HTD results are shown in the table below.

All results were less than Reporting Levels of GGNS ODCM Table 6.12.1-2.

Attachment 2 GNRO-2021/00015 Offsite Dose Calculation Manual

GRAND GULF NUCLEAR STATION OFFSITE DOSE CALCULATION MANUAL DOCKET NO. 50-416 INTRODUCTION The Offsite Dose Calculation Manual (ODCM) describes the methodology and parameters used in the calculation of offsite doses resulting from radioactive liquid and gaseous effluents, in the calculation of liquid and gaseous effluent monitoring Alarm/Trip Setpoints, and in the conduct of the Radiological Environmental Monitoring Program. The ODCM also contains (1) the Radioactive Effluent Controls and Radiological Environmental Monitoring Programs required by Technical Specification (TS) 5.5.4, and Technical Requirements Manual (TRM) 7.6.3.2, (2) descriptions of the information that is included in the Annual Radiological Environmental Operating and Annual Radioactive Effluent Release Reports required by TS 5.6.2 and 5.6.3, (3) a list and graphical description of the specific sample locations for the Radiological Environmental Monitoring Program, and (4) diagrams of the liquid and gaseous radwaste treatment systems.

The ODCM will be maintained at the station for use as a reference guide and training document of accepted methodologies and calculations. Changes in the calculational methods or parameters will be incorporated into the ODCM in order to assure that the ODCM represents the present methodology in all applicable areas.

Computer software to perform the described calculations will be maintained current with the ODCM.

Changes to the ODCM shall be accomplished as specified in TS 5.5.1. Records of reviews performed for changes made to the ODCM shall be retained for the duration of the Unit Operating License.

1.0 LIQUID EFFLUENTS 1.1 Liquid Effluent Monitor Setpoints 1.1.1 Liquid Radwaste Effluent Line Monitors Liquid Radwaste Effluent Line Monitors provide alarm and automatic termination of release prior to exceeding ten times the concentration limits specified in 10CFR20, Appendix B, Table 2, Column 2 at the release point to the unrestricted area. To meet this specification and for the purpose of implementation of LCO 6.3.9, the alarm/trip setpoints for liquid effluent monitors and flow measurement devices are set to assure that the following equation is satisfied:

cf C F + f (1) where:

C = ten times the effluent concentration limit (LCO 6.11.1) implementing 10CFR20 for the site, in Ci/ml.

c = The setpoint, representative of a radioactivity concentration in Ci/ml, of the radioactivity monitor measuring the radioactivity in the waste tank effluent line prior to dilution and subsequent release; the setpoint, which is inversely proportional to the volumetric flow of the effluent line and directly proportional to the volumetric flow of the dilution stream plus the waste tank effluent stream, represents a value which, if exceeded, would result in concentrations exceeding ten times the limits of 10CFR20 in the unrestricted area.

GRAND GULF, UNIT 1 1.0-1 Revision 42

f = the waste tank effluent flow setpoint as measured at the radiation monitor location, in volume per unit time, but in the same units as F, below.

F = the dilution water flow setpoint as measured prior to the release point, in volume per unit time.

At Grand Gulf Unit 1, the available dilution water flow (F) should be constant for a given release, and the waste tank flow (f) and monitor setpoint (c) are set to meet the condition of equation 1 for a given effluent concentration, C. The method by which this is accomplished is as follows:

Step 1) The isotopic concentration for a waste tank to be released is obtained from the sum of the measured concentrations as determined by the analysis required in ODCM Table 6.11.1-1:

C = C + C + C + C + C (2) i g a s t f i g s where:

C = the sum of concentrations C of each measured gamma g g g emitter observed by gamma-ray spectroscopy of the waste sample.

C = the concentration C of gross alpha emitters in a a liquid waste as measured in the monthly composite sample.

C = the measured concentrations of Sr-89 and Sr-90 in s s liquid waste as observed in the quarterly composite sample.

GRAND GULF, UNIT 1 1.0-2 Revision 42

C = the measured concentration of H-3 in liquid waste as t

determined from analysis of the monthly composite sample.

C = the concentration of Fe-55 in liquid waste as measured f

in the quarterly composite sample.

The C term will be included in the analysis of each waste g

tank batch to be released; terms for alpha, strontiums, tritium and iron are included if analysis of liquid waste has shown the presence of these isotopes.

Step 2) The measured radionuclide concentrations are used to calculate a Dilution Factor, D.F., which is the ratio of total dilution flow rate to waste tank effluent flow rate required to assure that ten times the limiting concentration of 10CFR20, Appendix B, Table 2, Column 2 are met at the point of discharge.

C i

D.F. = [ ] x S.F.

i EC i

C C C C C g a s t f

= [ + + + + ] x S.F. (3) g EC EC s EC EC EC g a s t f where:

C = C , C , C , C and C ; measured concentrations as i g a s t f defined in Step 1. Terms C , C , C and C will be a s t f included in the calculation as appropriate.

GRAND GULF, UNIT 1 1.0-3 Revision 42

EC = EC , EC , EC ,EC and EC are ten times the i g a s t f limiting concentrations of the appropriate radionuclide from 10CFR20, Appendix B, Table 2, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-4

µCi/ml total activity.

S.F. = an administrative safety factor normally applied at Grand Gulf which causes the calculated Dilution Factor to be two (2) times larger than the dilution factor required for compliance with ten times 10CFR20 limits.

Step 3) The maximum permissible waste tank effluent flow rate prior to dilution, f , is calculated based on a fixed fraction of d

the dilution flow rate, F :

d F + f F d d d f for F >>f d d d (4)

D.F. D.F.

where:

F = 0.9 x minimum expected dilution flow rate d

f = maximum permissible waste tank effluent flow rate d

D.F. = Dilution Factor from Step 2.

NOTE: Equation 4 is valid only for D.F.>1; for D.F.1, the waste tank effluent concentration meets the limits of ten times the limiting concentrations of 10CFR20 without dilution, and f may take on any desired value.

d Step 4) The dilution flow rate setpoint for minimum dilution flow rate, F, and waste tank flow rate setpoint for maximum waste tank effluent flow rate, f, are calculated as follows:

F = F = 0.9 x minimum expected dilution flow rate(5) d f = 0.9 x f = 0.9 x calculated maximum waste tank flow d

rate for the stated release conditions.(6)

GRAND GULF, UNIT 1 1.0-4 Revision 42

Thus, if instrumentation indicates the dilution flow rate falls below the assumed flow rate of 90 percent of the actual dilution flow, or if the waste tank effluent flow rate exceeds 90 percent of the calculated maximum waste tank effluent flow rate, the release is terminated (manually or automatically).

Step 5) The radioactivity monitor setpoint may now be specified based on the values of C , F, and f which were specified i i to provide compliance with ten times the limits of 10CFR20, Appendix B, Table 2, Column 2. The monitor response is primarily to gamma radiation; therefore, when determining the setpoint, Sp the summation of the gamma emitters in the tank is used and Sp is determined as follows:

Sp(cpm) = (fd/fa x Cg x MRF)

Where:

fd = maximum permissible waste tank effluent flow rate (gpm) fa = actual or maximum expected waste tank effluent flow rate (gpm)

Cg = Summation of all detected gamma emitters (uCi/ml)

MRF = Monitor Response Factor (cpm/uCi/ml) (Figure 1.0-1)(17)

For waste tanks where the quantity of gamma emitters does not produce a significant response above background, Sp, may be determined as follows:

If Sp = 0, i.e. no gamma emitters present, then Sp = 2700 cpm Or If Sp < (Monitor Error x Background), then Sp = (Monitor Error x Background). Provided that the error times the background is not greater than 2700 cpm.

GRAND GULF, UNIT 1 1.0-5 Revision 42

Note: 2700 cpm is based on Cesium-137 monitor response and the limits specified in LCO 6.11.1. (12)

The Monitor Error will normally be set at 25% (based on the calibration error)(17).

The liquid monitor trip setpoint = Sp + Monitor Background NOTE: Setpoint adjustments are not required if the existing setpoint corresponds to a lower count rate than the calculated value. The setpoint contains a factor of conservatism, even if the calculated maximum waste tank flow rate is attainable, since the calculated rate contains the safety factor margin, waste tank effluent flow rate margin, and the dilution flow rate margin. In practice, the actual waste tank effluent flow rate normally is many times less than the calculated tank flow rate, thus providing an additional conservatism during release.

1.2 Dose Calculations for Liquid Effluents 1.2.1 Maximum Exposed Individual Model The dose contribution to the maximum exposed individual from all radionuclides identified in liquid effluents released to unrestricted areas is calculated for the purpose of implementing LCO 6.11.2, 6.11.3, and TS 5.6.3 using the following expression:

m (1)

D = [A t C F ] (millirem) (8)

Tau iTau l il l i l=1 where:

A = Site-related ingestion dose commitment factor iTau for radionuclide i, in millirem/hr per Ci/ml.

= K U BF DF o F i i t = length of the time period over which C and F l il l are averaged for all liquid releases, in hours.

C = average concentration of radionuclide i observed il in the undiluted liquid effluent during time period tl from any liquid release in Ci/ml.

Concentrations are determined in accordance with the requirements of Table 6.11.1-1, 6.12-1-1 and 6.12.1-3. For composite samples, the last measured value from the most recent monthly and quarterly composite samples will be used in the dose calculation.

NOTE: LLD values are not used in dose calculations.

GRAND GULF, UNIT 1 1.0-7 Revision 42

F = Dilution factor for C during any liquid effluent l il release. For releases via the discharge basin, F1 is the dilution in the near field and is defined as the ratio of the average undiluted liquid waste flow during release to the product of the average flow from the site discharge structure to unrestricted (5) receiving waters times the applicable factor of 2

= average undiluted liquid waste flow average flow from site discharge x 2 For releases via the 007 outfall, F1 is defined as the 007 outfall runoff to the total runoff into Hamilton Lake. It is the environmental dilution derived from the lowest historical annual precipitation as recorded in the FSAR = 0.10(18) 5 K = units conversion factor 1.14 x 10 o

6 3

= 10 pCi x 10 ml 8766 hr Ci kg yr (3)

U = adult fish consumption (21 kg/yr) .

F BFi = Bioaccumulation factor for each nuclide, i, in fish, in pCi/kg per pCi/1 from ODCM Table 1.2-1.

DFi = Dose conversion factor for each nuclide, i, for adults in preselected organ, Tau, in mrem/pCi, from ODCM Table 1.2-2.

Calculated values of A for radionuclides which might be iTau observed in liquid effluents are given in ODCM Table 1.2-3.

1.2.2 Dose Projection Doses from liquid effluents to UNRESTRICTED AREAS are projected at least every 31 days as required by LCO 6.11.3.

These projections are made by averaging the doses (D )

Tau from previous operating history (normally the previous six months) which is indicative of expected future operations.

1.3 Liquid Radwaste Treatment System The essential components of the liquid radwaste treatment system are indicated by an asterisk (*).

The radwaste system includes provisions for use of alternate liquid radioactive processing equipment. This system may be used in place of the precoat filters and may contain striners, carbon bed filters, cartridge filters, a reverse osmosis unit or other components which process liquid radioactive wastes. Bypassing the precoat filter (an essential component) is acceptable provided that the effluent from the alternative system provides the same level of filtration required for the precoat filters.

NOTES for Figure ODCM 1.3-1 (1) The essential components outlined on the following page are those necessary to collect, process and sample liquid radwaste prior to discharge to the environment.

(2) Only one of the following is required in order to process liquid waste.

a. Equipment drain filter

b. Floor drain filter

c. Equipment drain demineralizer

d. Floor drain demineralizer (3) The Waste Surge Tanks may be used to replace the Waste Collection Tanks.

2.0 GASEOUS EFFLUENTS 2.1 Gaseous Effluent Monitor Setpoints 2.1.1 Continuous Ventilation Monitors For the purpose of implementation of LCO 6.3.10, the alarm setpoint level for continuous ventilation noble gas monitors will be calculated as follows:

S = count rate (cpm) above background of vent noble gas V

monitor at the alarm setpoint level PF x R x D t TB

= the lesser of or PF x R x D s ss where:

NOTES For Section 2.1.1

1) The calculated setpoint values will determine the allowable bounds for the actual setpoint adjustments. That is, setpoint adjustments are not required to be performed if the existing setpoint level corresponds to a count rate that is less than or equal to + 25% of the calculated value.

If radionuclides are not detected in the grab sample, then the previously calculated setpoint may remain as the valid setpoint.

2) A conservative setpoint may be calculated using a composite total body dose factor. This method may be used when there are no valid isotopics available. The conservative setpoint will be calculated as follows:

S = count rate (cpm) above background of vent noble gas monitor at the v

alarm setpoint level*

PF = product of allocation factor (AF) and safety factor (SF'), normally set at 0.1 AF = allocation factor allowing for a total of four normal effluent release points, normally set at 0.25 SF' = safety factor allowing for cumulative uncertainties of measurements, normally set at 0.4.

2.3 Meteorological Model 2.3.1 Atmospheric Dispersion (Annual Average)

The XOQDOQ software, NUREG/CR-2919, Computer Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations, or similar, should be used to calculate atmospheric dispersion factors for routine continuous long term releases. Software input parameters use the normal settings as described in Table 2.1 of NUREG/CR-2919 with the following exceptions:

Calm values are distributed in a separate windspeed category (i.e., 1st windspeed category) with the same proportion and direction as the direction frequency of the 2nd windspeed class. (Reference 10,14,15)

No terrain recirculation factor is applied. (Reference 5, Section 3A) 0.224 m/sec for calm (Reference 7, 15) 14 windspeed categories are used (Reference 14,15) 7 stability clases, A-G (Reference 10,14,15) 1 release exit point (Reference 10,14,15) 10 meter for measured wind, ground level release (Reference 7, 10, 14, 15)

No decay Normally, maximum windspeed categories are 0.224, 0.5, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 4.00, 5.00, 7.00, 13.00 (m/sec) (Reference 14, 15)

Height of vents release point = 31 meters (Reference 15)

Height of vents building = 53.3 meters (Reference 15)

Minimum cross-sectional area for the vents building =

2729 meters2 (Reference 14, 15)

2.3.2 Atmospheric Dispersion (Hourly Average)

The atmospheric dispersion for gaseous releases may be calculated using a ground level, wake-split form of the straight line flow model.

X/Q = atmospheric dispersion (sec/m³)

2.03 k ru where:

r = distance (m) from release point to location of interest

= plume depletion factor at distance r from ODCM Figure 2.3-1 u = hourly average wind speed at ground level (m/sec) k = open terrain recirculation factor at distance r,

2.6 Annual Dose Commitment If required, the annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC will be calculated by summing the following doses for the calendar year:

Direct radiation dose

Liquid effluent dose (D )

Tau

Noble gas dose (D , D )

Particulate dose (D )

p These calculations are required only if the liquid or gaseous effluents exceed twice the limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

2.6.1 Direct Radiation Dose Measurement LCOs 6.11.2, 6.11.5 and 6.11.6 require the determination of cumulative dose contributions to a MEMBER OF THE PUBLIC from direct radiation from the reactor units and from radwaste storage tanks. This requirement is applicable only under conditions set forth in Action B.1 of the applicable LCO.

This determination is made by the utilization of direct radiation measurements from indicator thermoluminescent dosimeters (TLDs) located near the GGNS property line.

GRAND GULF, UNIT 1 2.0-36 Revision 42

Measurements from these TLDs represent the direct radiation generated by the facility plus normal background radiation.

The locations are identified in ODCM Table 3.0-3 by the following TLD numbers:

M-16 M-22 M-23 M-97 M-100 M-19 M-25 M-95 M-98 M-21 M-28 M-96 M-99 Control TLDs are also utilized to differentiate between background radiation and direct radiation from the facility.

The following two TLDs are designated as controls based on the criterion that they are located ten miles or greater from the facility. Exact locations are identified in ODCM Table 3.0-3.

M-14 M-33 The difference between the averaged quarterly radiation measurements of the indicator TLDs and the control TLDs represents the direct radiation dose to a MEMBER OF THE PUBLIC from the operating facility.

E V 2.22 x 106 Y exp(-t) where LLD is the "a priori" lower limit of detection as defined above (as µCi per unit mass or volume). (Current literature defines the LLD as the detection capability for the instrumentation only, and the MDC, minimum detectable concentration, as the detection capability for a given instrument, procedure, and type of sample.)

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 x 106 is the number of disintegrations per minute per microcurie Y is the fractional radiochemical yield (when applicable) is the radioactive decay constant for the particular radionuclide t is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of sb used in the calculation of the LLD for a particular measurement system should 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 predicated variance.

Typical values of E, V, Y and t 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 a posteriori (after the fact) limit for a particular measurement.

a. The LLD is 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):

4.66 sb LLD =

E V 2.22 x 106 Y exp (-t) where LLD is the "a priori" lower limit of detection as defined above (as µCi per unit mass or volume). (Current literature defines the LLD as the detection capability for the instrumentation only, and the MDC, minimum detectable concentration, as the detection capability for a given instrument, procedure, and type of sample.)

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 x 106 is the number of disintegrations per minute per microcurie Y is the fractional radiochemical yield (when applicable) is the radioactive decay constant for the particular radionuclide t is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of sb used in the calculation of the LLD for a particular measurement system should 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 predicated variance.

Typical values of E, V, Y and t 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 a posteriori (after the fact) limit for a particular measurement.

Refer to NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," October 1978, and to Radiological Assessment Branch Technical Position, Revision 1, November 1979. 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 effort shall be made to complete corrective action before the end of the next sampling period. All above deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report.

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. Identify the cause of the unavailability of samples for that pathway and identify the new location(s) for obtaining replacement samples in the next Annual Radioactive Effluent Release Report and also include in the report a revised figure(s) and table(s) for the ODCM reflecting the new location(s).

6.11 RADIOACTIVE EFFLUENTS BASES LIQUID EFFLUENTS 6.11.1 CONCENTRATION This LCO is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than ten times the effluent concentration values specified in Appendix B, Table 2, Column 2 to 10 CFR 20.1001-20.2402. It provides operational flexibility for releasing liquid effluents in concentrations to follow the Section II.A and II.C design objectives of Appendix I to 10 CFR Part 50. This limitation provides reasonable assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR 50, to a MEMBER OF THE PUBLIC, and (2) restrictions authorized by 10 CFR 20.1301(e). The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radionuclide and its effluent concentration in air (submersion) was converted to an equivalent concentration in water. This LCO does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301(a).

The results of pre-release analyses and post release analyses (of composited samples) shall be used with the calculational methods and parameters in the ODCM to assure that the concentrations at the point of release are maintained within the limits.

The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs). Detailed discussion of the LLD, and other detection limits, can be found in:

(1) HASL Procedures Manual, HASL-300.

(2) Currie, L. A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968).

6.11.2 DOSE This LCO is provided to implement the requirements of Sections II.A, III.A and IV.A of Appendix I, 10 CFR Part 50. 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 which assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS 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 40 CFR 141. The dose calculations in the ODCM 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.

RADIOACTIVE EFFLUENTS BASES 6.11.2 DOSE (Continued)

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 Effluent from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

This LCO, in conjunction with LCOs 6.11.5 and 6.11.6 is also provided to meet the dose limitation of 40 CFR 190 that has been incorporated into 10 CFR 20.1301(d).

Even if a site contained up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 190 if the individual reactors remain within twice the dose design objectives of 10 CFR 50 Appendix I, and the direct radiation doses from the units (including outside storage tanks, etc.) are kept small.

Special Report:

LCO 6.11.2 requires preparation and submittal of a report in accordance with 10 CFR 50.4 and as defined in 10 CFR 20.2203(a)(4), if the dose design objectives of 10 CFR 50 Appendix I are exceeded.

If either the quarterly or the annual limit is exceeded, the report will:

(1) identify the cause(s) for exceeding the limit(s),

(2) define the corrective actions that have been taken to reduce the releases, and (3) define the corrective actions to be taken to ensure that future releases will be in compliance with the limits.

If a drinking water supply is taken from the receiving water body within three miles downstream of the plant discharge, the report shall also include:

(1) results 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.

If the doses exceed the limits of 40 CFR 190, 25 mrems to the whole body or any organ, except the thyroid, which is limited to 75 mrems, the report shall:

(1) define the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits, (2) include the schedule for achieving conformance with the above limits, (3) include an analysis that 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, (4) describe the levels of radiation and concentrations of radioactive material involved, (5) describe the cause of the exposure level or concentrations involved, GRAND GULF, UNIT 1 A-63 Revision 42

RADIOACTIVE EFFLUENTS BASES 6.11.2 DOSE (Continued)

(6) 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 190 limits.

For the purposes of the 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 the dose distribution from other nuclear fuel cycle facilities at the same site or within a radius of 8 kilometers must be considered.

The Special Report with a request for a variance (provided the release conditions resulting in a violation of 40 CFR 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and 10 CFR 20.2203(a)(4), is considered to be a timely request and fulfills the requirements of 40 CFR 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR 190, and does not apply in any way to other requirements for dose limitations of 10 CFR 20, as addressed in LCOs 6.11.1 and 6.11.4. 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.

Demonstration of compliance with the limits of 40 CFR 190 or with the design objectives of Appendix I to 10 CFR 50 will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301.

RADIOACTIVE EFFLUENTS BASES 6.11.3 LIQUID WASTE TREATMENT The LCO 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 LCO 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 specified limit governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

Special Report:

LCO 6.11.3 requires preparation and submittal of a report in accordance with 10 CFR 50.4 if radioactive liquid waste is being discharged without treatment and in excess of the limits. The report shall include:

(1) an explanation why liquid radwaste was being discharged without treatment, (2) identification of any nonfunctional equipment or subsystems which resulted in liquid radwaste being discharged without treatment, (3) the reason for the nonfunctionality (4) action(s) taken to restore the nonfunctional equipment to an FUNCTIONAL status, (5) summary descriptions of actions taken to prevent a recurrence.

GASEOUS EFFLUENTS 6.11.4 DOSE RATE This LCO provides reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either at or beyond the SITE BOUNDARY in excess of the design objectives of Appendix I to 10 CFR Part 50. This specification is provided to ensure that gaseous effluents from all units on the site will be appropriately controlled. It provides operational flexibility for releasing gaseous effluents to satisfy the Section II.A and II.C design objectives of Appendix I to 10 CFR Part

50. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for the reduced atmosphere dispersion of gaseous effluents relative to that for the SITE BOUNDARY. The calculational methods and parameters in the ODCM are used to assure that the dose rates are maintained within the limits. Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given in the ODCM. The specified release rate limits restrict, at all times, the corresponding 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. These releases rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem/year. This specification does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301(a).

The dose rate due to radioactive gaseous effluents shall be determined in accordance with the methodology and parameters of the ODCM.

6.11.5 DOSE - NOBLE GASES This LCO is provided to implement the requirements of Sections II.B, III.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.B 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 gaseous effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable."

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 dose calculations established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous 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 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977. The ODCM equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

This LCO, in conjunction with LCOs 6.11.2 and 6.11.6 is also provided to meet the dose limitation of 40 CFR 190 that has been incorporated into 10 CFR 1301(d). Even if a site contained up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 190 if the individual reactors remain within twice the dose design objectives of 10 CFR 50 Appendix I, and if the direct radiation doses from the units (including outside storage tanks, etc.) are kept small.

The Limiting Conditions for Operation are the guides set forth in Section II.C 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 materials in gaseous effluents to UNRESTRICTED AREAS 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 methods 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 specifications for iodine-131, iodine-133, tritium and radionuclides in particulate form are dependent on the existing radionuclide pathway to man in the areas at and beyond the SITE BOUNDARY. The pathways which were examined in the development of these calculations were: (1) individual inha-lation 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.

RADIOACTIVE EFFLUENTS BASES 6.11.7 and 6.11.8 GASEOUS RADWASTE TREATMENT AND VENTILATION EXHAUST TREATMENT The FUNCTIONALITY of the GASEOUS RADWASTE TREATMENT (OFFGAS) SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that the system will be available for use whenever gaseous effluents require treatment before release to the environment.

The requirement that the appropriate portions of the system be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reasonably achievable." This specification 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 II.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the system were specified as a suitable fraction of the dose design objectives set forth in Section II.B and II.C of Appendix I, 10 CFR 50, for gaseous effluents.

Special Report:

LCOs 6.11.7 and 6.11.8 require preparation and submittal of a report in accordance with 10 CFR 50.4 including:

6.12 RADIOLOGICAL ENVIRONMENTAL MONITORING BASES 6.12.1 MONITORING PROGRAM The radiological monitoring program required by this LCO provides 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 PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 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. The initially specified monitoring program will be effective for at least the first three years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The detection capabilities required by Table 6.12.1-3 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an "a priori" (before the fact) limit representing the capability of a particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

For a more complete discussion of the LLD, and other detection limits, see the following:

(1) HASL Procedure Manual, HASL-300 (revised annually).

(2) Currie, L. A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal.Chem. 40, 586-93 (1968).

(3) Hartwell, J. K., "Detection Limits for Radioisotopic Counting Techniques,"

Atlantic Richfield Hanford Company Report ARH-2537 (June 22, 1972).

If milk or broadleaf vegetation sampling locations are relocated, the cause shall be reported in the next Annual Radioactive Effluent Release Report. Also, include in this report, revised ODCM figure(s) and table(s) reflecting the new locations. The specific locations from which samples were unavailable may then be deleted from the radiological environmental monitoring program and the table(s) in the ODCM, provided the locations from which the replacement samples were obtained are added to the table(s) as replacement locations.

The requirement for participation in an approved Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measures of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10 CFR Part 50.

6.12 RADIOLOGICAL ENVIRONMENTAL MONITORING BASES 6.12.1 MONITORING PROGRAM (Continued)

Special Report:

LCO 6.12.1 requires preparation and submittal of a report in accordance with 10 CFR 50.4 when:

(1) the level of radioactivity as a result of plant effluents in an environmental sampling medium at a specified location exceeds the reporting level(s) in ODCM Table 6.12.1-2 when averaged over a calendar quarter, or (2) more than one of the radio nuclides in ODCM Table 6.12.1-2 are detected in the sampling medium and concentration (1) + concentration (2) + ...1.0, or reporting level (1) reporting level (2)

(3) radio nuclides other than those in ODCM Table 6.12.1-2 are detected, and the potential annual dose to a MEMBER OF THE PUBLIC is equal to or greater than the calendar year limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

The report shall:

(1) identify the cause(s) for exceeding the limit(s), and (2) define the corrective actions to be taken to reduce radioactive effluents so the potential annual dose to a MEMBER OF THE PUBLIC is less than the calendar year limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

The Special Report is not required if the measured level of radioactivity is not the result of plant effluents; however in such an event, the condition shall be reported and identified in the Annual Radiological Environmental Operating Report.

6.12.2 LAND USE CENSUS This LCO is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made if required by the results of the census.

The best information from door-to-door survey, visual or aerial survey or from consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50.

Restricting the census to gardens of greater than 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/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 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/m2.

Specifications for broad leaf vegetation sampling in the Table 6.12.1-1 shall be followed, including analysis of control samples.

6.12 RADIOLOGICAL ENVIRONMENTAL MONITORING BASES 6.12.2 LAND USE CENSUS (Continued)

The land use census should utilize information which provides the best results, such as a door-to-door-survey, an aerial survey or by consulting local agriculture authorities. The results of the land use census shall be included in the Annual Radiological Environmental Operating Report pursuant to Technical Specification 5.6.2.

When the Land Use Census requires addition of sampling location(s) to the Environmental Monitoring Program, the sampling locations(s) having the lowest calculated dose or dose commitments(s), via the same exposure pathway, may be deleted from the monitoring program. This deletion may take place after October 31 of the year in which this land use census was conducted.

The new sampling location(s) shall be identified in the next Annual Radioactive Effluent Release Report including a revised figure(s) and table(s) for the ODCM.
