SECTION I. INTRODUCTION 7

I. INTRODUCTION This report contains a complete tabulation of data collected during the period January 1 through December 31 2020, for the operational Radiological Environmental Monitoring Program (REMP) performed for Cooper Nuclear Station (CNS) of Nebraska Public Power District (NPPD) by Teledyne Brown Engineering - Environmental Services.

Cooper Nuclear Station is located in Nemaha County in the southeast comer of Nebraska on the Missouri River. A portion of the site extends into Missouri. The reactor is an 830-megawatt (net electrical) boiling water reactor. Initial criticality was attained on February 21, 1974.

Radiological environmental monitoring began in 1971 before the plant became operational and has continued to the present. The program monitors radiation levels in air, terrestrial and aquatic environments. All samples are collected by NPPD personnel. All samples are shipped for analysis to a contractor's laboratory where there exists special facilities required for measurements of extremely low levels of radioactivity. Teledyne Brown Engineering - Environmental Services has the responsibility for the analyses for Cooper Nuclear Station.

The United States Nuclear Regulatory Commission (USNRC) regulations (10CFR50.34a) require that nuclear power plants be designed, constructed, and operated to keep levels of radioactive material in effluents to unrestricted areas as low as is reasonably achievable (ALARA). Inplant monitoring is used to ensure that release limits are not exceeded. As a precaution against unexpected or undefined environmental processes, which might allow undue accumulation of radioactivity in the environment, a program for monitoring the plant environs is included in NPPD's CNS Offsite Dose Assessment Manual (ODAM).

A. Atmospheric Nuclear Tests and Nuclear Incidents Three atmospheric nuclear detonations in the People's Republic of China influenced program results significantly in late 1976 and in 1977. Two of these detonations occurred in late 1976 (September 26 and November 17) and one in late 1977 (September 17). As a consequence of these tests elevated activities of gross beta in air particulate filters and iodine-131 in milk were observed throughout most of the United States. No atmospheric nuclear tests have been conducted since 1980, thus no short-lived fission products were detected in air particulate samples.

On April 26, 1986 the fire and explosion of Chernobyl Reactor No. 4 in the Soviet Union resulted in the release of fission products to the atmosphere and worldwide fallout.

Following the explosion, elevated levels of gross beta activities in air particulates and iodine-131 in charcoal filters and milk samples were measured. Additionally, in 1986, cesium-13 7 and the short-lived radionuclides iodine-131, ruthenium- I 06, and cesium-134 were detected in broadleaf vegetation. Similar results occurred in other areas of the United States and the entire Northern Hemisphere.

B. Monitoring Program Objectives and Data Interpretation The objective of the monitoring program is to detect and assess the impact of possible releases to the environs of radionuclides from the operations of Cooper Nuclear Station.

This objective requires measurements of low levels of radioactivity equal to or lower than pre-determined limits of detection. In addition the source of the environmental radiation must be established. Sources of environmental radiation include:

(1) Natural background radiation from cosmic rays (beryllium-7).

(2) Terrestrial, primordial radionuclides from the environment (potassium-40, radium-226, thorium-228).

(3) Fallout from atmospheric nuclear tests such as the September 1977 detonation by the Peoples' Republic of China and the atmospheric weapons test of October 16, 1980 (fission products and fusion products).

(4) Releases from nuclear power plants such as CNS (fission products and neutron activation products).

(5) Fallout from the Chernobyl nuclear reactor accident.

Radiation levels measured in the vicinity of an operating power station are compared with preoperational measurements at the same locations to distinguish power plant effects from other sources. Also, results of the monitoring program are related to events known to cause elevated levels of radiation in the environment, e.g., atmospheric nuclear detonations or abnormal plant releases.

SUMMARY

AND DISCUSSION OF 2020 ANALYTICAL RESULTS Data from the radiological analyses of environmental media collected during 2020 are tabulated and discussed in section A through H. The procedures and specifications followed in the laboratory for these analyses are as required in the Teledyne Brown Engineering Quality Assurance manual and are explained in the Teledyne Brown Engineering Analytical Procedures. A synopsis of analytical procedures used for the environmental samples is provided in Appendix C. In addition to internal quality control measures performed by Teledyne Brown Engineering, the laboratory also participates in an Interlaboratory Comparison Program. Participation in this program ensures that independent checks on the precision and accuracy of the measurements of radioactive material in environmental samples are performed. The results of the Interlaboratory Comparison are provided in Appendix B.

Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods. The "less than" values in the data tables were calculated from each specific analysis and are dependent on sample size, detector efficiency, length of counting time, chemical yield (when appropriate) and the radioactive decay factor from time of counting to time of collection. Teledyne Brown Engineering's analytical methods meet or are below the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, Radiological Monitoring Acceptable Program (November 1979, Revision 1). Appendix C contains a discussion of the LLD formulas.

The following is a discussion and summary of the results of the environmental measurements taken during the 2020 reporting period:

20

A. Airborne Particulates Gross beta activity was observed in 433 of the 464 indicator samples collected during 2020. The average concentration was 0.014 pCi/m3 with a range of0.003 to 0.037 pCi/m3 . Gross beta activity was observed in 49 of the 52 control samples with an average concentration of 0.012 pCi/m3 with a range of 0.004 to 0.022 pCi/m3 .

The results of the gross beta activities are presented in Section VII-I and Trending Graph 1. The gross beta activities for 2020 were comparable to levels measured in the previous several years. Prior to that period the gross beta activities were higher due to atmospheric nuclear weapons testing performed in other countries. The preoperational period of 1971 through 1974 averaged 0.098 pCi/m3 gross beta.

Air particulate filters were collected weekly and composited by locations on a quarterly basis, unless otherwise specified in Section VII-2. They were analyzed by gamma ray spectroscopy. The results are presented in Section VII-2. Beryllium-7, which is produced continuously in the upper atmosphere by cosmic radiation, was measured in 42 of the 42 composite samples. The indicator locations had an average concentration of 0.092 pCi/m3 with a range of 0.050 to 0.155 pCi/m3 . The control location had an average concentration of0.084 pCi/m3 with a range of0.048 to 0 .13 3 pCi/m3 . During the preoperational period, beryllium-7 was measured at comparable levels. All other gamma emitters were below the detection limits. The operation of Cooper Nuclear Station has no discemable impact on Airborne Particulate samples.

C. Fish Aquatic biota can be sensitive indicators of radionuclide accumulation in the environment because of their ability to concentrate certain chemical elements, which have radioisotopes. The results are presented in Table VII-3 and Trending Graph 3. Two samples of fish were collected during the summer and fall of 2020.

Middle-top feeding fish (carp) and bottom feeding fish (catfish) were collected in June and September. These samples were analyzed by gamma ray spectroscopy.

Naturally occurring potassium-40 was detected in all samples. The average concentration at the upstream control location was 2,489 pCi/kg (wet weight) with a range of 1,879 to 2,963 pCi/kg (wet weight). The average concentration for the indicator samples was 3,075 pCi/kg (wet weight) with a range of 2,234 to 3,582 pCi/kg (wet weight). The preoperational period of 1971 through 1974 averaged 2,400 pCi/kg potassium-40. All other gamma emitters were below the lower limit of detection. The operation of Cooper Nuclear Station has had no discemable impact on fish samples.

D. Milk - Nearest Producer Milk samples are collected once every 15 days in peak pasture season and once every 31 days the rest of the year from Station 99. The results are presented in Table VII-4 and Trending Graph 4. Seventeen samples were analyzed by gamma ray spectroscopy and for low-level iodine-131 by radiochemical separation. All iodine-131 results were below the lower limit of detection. Naturally occurring potassium-40 was measured in all samples with an average concentration of 1,200 pCi/L and a range of 971 to 1,498 pCi/L. All other gamma emitters were below the lower limit of detection. The operation of Cooper Nuclear Station has no discemable impact on milk samples.

G. Thermoluminescent Dosimeters Thermo luminescent dosimeters (TLDs) determine environmental radiation doses and the results are presented in Table VII-7 and Trending Graph 7. Ambient radiation was monitored at 58 locations within an 11 mile radius of Cooper Nuclear Station and collected quarterly. The average concentration for the indictor locations was 21.2 millirem/quarter and a range from 18.0 to 26.0 millirem/quarter. The highest indicator station N20, which is located 2.9 miles, 200 degrees, had an average of 23.3 millirem/quarter and a range from 22.0 to 25.0 millirem/quarter.

The control stations were Station 44 and Station 111 with an average of 22.3 millirem/quarter and a range from 20.0 to 24.0 millirem/quarter. The preoperational period of 1971 through 1974 averaged 37. 0 millirem/quarter; which is the preoperational four year average. Current year TLD averages deviate from the preoperational averages due to instrument variations from previous vendors.

The data from year to year is in good agreement and indicates no adverse changes in radiation exposure to the population near Cooper Nuclear Station.

APPENDIX A 2020 LAND USE CENSUS A-1

ANNUAL CNS LAND USE CENSUS/ POTABLE WATER USE Conducted July 23, 2020 0-3 miles Cooper Nuclear Station (CNS) Offsite Dose Assessment Manual (ODAM) requires an annual land use census. This census identifies the location of the nearest garden that is greater than 500 square feet in area and yields leafy green vegetables, the nearest milk animal, and the location of the nearest resident in each of the 16 meteorological sectors within 3 miles of CNS.

A land use census was performed July 23, 2020, in accordance with the CNS ODAM.

The nearest residence was found in sector Q, 0.9 miles from CNS, and the nearest garden was found in sector D, 1. 7 miles from CNS.

No milk animals were found within 3 miles of CNS and there was no evidence of potable water use from the Missouri River within three miles of CNS.

SUMMARY

OF INTRALABORATORY COMPARISONS B-1

INTERLABORATORY COMPARISION PROGRAM The purpose of the Interlaboratory Comparison Program (ICP) is to confirm the accuracy of results produced by Teledyne Brown Engineering. Samples of various matrices (i.e. soil, water, vegetation, air filters, and milk) are spiked with known amounts of radioactivity by commercial vendors of this service and by departments within the government. TBE participates in three programs. Two are commercial, Analytics Inc. and Environmental Resource Associates (ERA) and one is a government sponsored program, the Department of Energy's (DOE) Mixed Analyte Performance Evaluation Program (MAPEP). The DOE's MAPEP was created to mimic conditions found at DOE sites which do not resemble typical environmental samples obtained at commercial nuclear power facilities.

All three programs are blind performance evaluation studies in which samples with known activities are sent to TBE for analysis. Once analyzed, TBE submits the results to the respective agency for evaluation. The results of these evaluations are published in TBE's quarterly and annual QA reports.

The National Institute of Standards and Technology (NIST) is the approval authority for laboratory providers participating in Intercomparison Study Programs; however, at this time, there are no approved laboratories for environmental and/or radiochemical isotope analyses.

For the TBE laboratory, 126 out of 133 analyses performed met the specified acceptance criteria. Seven analyses did not meet the specified acceptance criteria and were addressed through the TBE Corrective Action Program. A summary of the NCR dispositions is provided.

NCR 20-13: The MAPEP February 2020 AP U-233/234 and U-238 results were evaluated as Not Acceptable. The reported value for U-233/234 was 0.0416 +/-

0.0102 Bq/sample and the known result was 0.075 Bq/sample (acceptance range 0.053 - 0.098). The reported value for U-238 was 0.0388 +/- 0.00991 Bq/sample and the known result was 0.078 Bq/sample (acceptance range 0.055 - 0.101). This sample was run as the workgroup duplicate and had RPD's of 10.4% (U-234) and 11.7% (U-238). After the known results were obtained, the sample was relogged.

The filter was completely digested with tracer added originally; the Rl results were almost identical. It was concluded that the recorded tracer amount was actually double, causing the results to be skewed. Lab worksheets have been modified to verify actual tracer amount vs. LIMS data. TBE changed vendors for this cross-check to ERA MRAD during the 2nd half of 2020. Results were acceptable at 97.8% for U-234 and 106% for U-238.

NCR 20-19: The Analytics September 2020 milk Sr-89 result was evaluated as Not Acceptable. The reported value was 62.8 pCi/L and the known result was 95.4

( 66% ). All QC data was reviewed and there were no anomalies. This was the first failure for milk Sr-89 since 2013 and there have only been 3 upper/lower boundary warnings since that time. It is believed that there may have been some Sr-89 loss during sample prep. The December 2020 result was at 92% of the known.

NCR 20-17: The ERA October 2020 water 1-131 result was evaluated as Not Acceptable. The reported value was 22.9 pCi/L and the known result was 28.2 (acceptance range 23. 5 - 3 3 .1). The reported result was 81 % of the known, which passes TBE QC criteria. This was the first failure for water 1-131.

NCR 20-18: The ERA October 2020 water Gross Alpha and Gross Beta results were evaluated as Not Acceptable. The reported/acceptable values and ranges are as follows: Reported Known Range Gross Alpha 40.0 26.2 13 .3 - 34. 7 Gross Beta 47.5 69.1 48.0 - 76.0 All QC data was reviewed with no anomalies and a cause for failure could not be determined. This was the first failure for water Gross Beta. A Quick Response follow-up cross-check was analyzed as soon as possible with acceptable results at 96.8% for Gross Alpha and 102% for Gross Beta.

DETERMINATION OF GROSS BET A ACTIVITY IN WATER SAMPLES Introduction The procedures described in this section are used to measure the overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.

One liter of the sample is evaporated on a hot plate. A smaller volume may be used if the sample has a significant salt content as measured gravimetrically. If requested by the customer, the sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size.

After evaporating to a small volume in a beaker, the sample is rinsed into a 2-inch diameter stainless steel planchette, which is stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps.

Residue mass is determined by weighing the planchette before and after mounting the sample. The planchette is counted for beta activity on an automatic proportional counter. Results are calculated using empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass.

Detection Capability Detection capability depends upon the sample volume actually represented on the planchette, the background and the efficiency of the counting instrument, and upon self-absorption of beta particles by the mounted sample. Because the radioactive species are not identified, no decay corrections are made and the reported activity refers to the counting time.

The minimum detectable level (MDL) for water samples is nominally 1.6 picoCuries per liter for gross beta at the 4.66 sigma level (1.0 pCi/L at the 2.83 sigma level), assuming that 1 liter of sample is used and that 0.5 gram of sample residue is mounted on the planchette. These figures are based upon a counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively The MDL becomes significantly lower as the mount weight decreases because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MDL for gross beta is 0.9 pCi/L. These values reflect a beta counting efficiency of 0.38.

ANALYSIS OF SAMPLES FOR TRITIUM (Liquid Scintillation)

Water Ten milliliters of water are mixed with 10 ml of a liquid scintillation "cocktail" and then the mixture is counted in an automatic liquid scintillator.

Calculation of the results, the two sigma error and the lower limit detection (LLD) in pCi/L:

RESULT (N-B)/(2.22 VE) 1/2 TWO SIGMA ERROR 2((N + B)/~t) I (2.22 VE) 1/2 LLD 4.66(B/~t) . /(2.22 VE) where: N the gross cpm of the sample B the background of the detector in cpm 2.22 conversion factor changing dpm to pCi V volume of the sample in ml E efficiency of the detector M counting time for the sample C-5

ANALYSIS OF SAMPLES FOR IODINE-131 Milk or Water Two or more liters of sample are first equilibrated with stable iodide carrier. A batch treatment with anion exchange resin is used to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, is reduced with hydroxylamine hydrochloride and is extracted into carbon tetrachloride as free iodine. It is then back-extracted as iodide into sodium bisulfite solution and is precipitated as palladium iodide. The precipitate is weighed for chemical yield and is mounted on a nylon planchette for low-level beta counting.

Calculations of results, two sigma error and the lower limit of detection (LLD) in pCi/L:

RESULT (NI M-B)/(2.22 EVY DF) 1/2 TWO SIGMA ERROR 2((N/ ~t+B)/ ~t) /(2.22 EVY DF) 1/2 LLD 4.66(B/~t) /(2.22 EVY DF) where: N total counts from sample (counts)

Es efficiency of the counter determined from an 1-131 standard mount Ms mass of Pdl 2 on the standard mount, mg M mass of Pdl 2 on the sample mount, mg C-6

GAMMA SPECTROMETRY OF SAMPLES Milk or Water A 1.0 or 4.0 liter Marinelli beaker is filled with a representative aliquot of the sample. The sample is then counted until detection limits are met with a shielded high purity germanium (HPGe) detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Dried Solids other than Soils and Sediments A large quantity of the sample is dried at a low temperature, less than 100°C.

As much as possible (up to the total sample) is loaded into a tare, standard 240 cc container and weighed. The sample is then counted until detection limits are met with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Fish As much as possible (up to the total sample) of the edible portion of the sample is loaded into a tared Marinelli and weighed. The sample is then counted until detection limits are met with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height analysis.

Soils and Sediments Soils and sediments are dried at a low temperature, less than 100°C. The soil or sediment is loaded fully into a tared, standard 240 cc container and weighed. The sample is then counted until detection limits are met with a shielded HPGe detector coupled to a VAX-based data acquisition system, which performs pulse height and analysis.

Charcoal Cartridges (Air Iodine)

Charcoal cartridges are counted up to five at a time, with one positioned on the face of an HPGe detector and up to four on the side of the HPGe detector. Each HPGe detector is calibrated for both positions. The detection limit for iodine-131 of each charcoal cartridge can be determined (assuming no positive iodine-131) uniquely from the volume of air, which passed through it. In the event iodine-131 is observed in the initial counting of a set, each charcoal cartridge is then counted separately, positioned on the face of the detector.

C-7

Air Particulates The thirteen airborne particulate filters for a quarterly composite for each field station are aligned one in front of another and then counted until detection limits are met with a shielded HPGe detector coupled to a VAX-based data acquisition system which performs pulse height analysis.

A VAX software program defines peaks by certain changes in the slope of the spectrum. The program also compares the energy of each peak with a library of peaks for isotope identification and then performs the radioactivity calculation using the appropriate fractional gamma ray abundance, half-life, detector efficiency, and net counts in the peak region.

The calculation of results, two sigma error and the lower limit of detection (LLD) in pCi/volume or pCi/mass:

RESULT (S-B)/(2.22 t EV F DF) 1/2 TWO SIGMA ERROR 2(S+B) /(2.22 t EV F DF) 1/2 LLD 4.66(8) /(2.22 t EV F DF) where: s Area, in counts, of sample peak and background (region of spectrum of interest)

B Background area, in counts, under sample peak, determined by a linear interpolation of the representative backgrounds on either side of the peak t length of time in minutes the sample was counted 2.22 dpm/pCi E detector efficiency for energy of interest and geometry of sample V sample aliquot size (liters, cubic meters, kilograms, or grams)

F fractional gamma abundance ( specific for each emitted gamma)

ADDENDUM TO GAMMA SPECTROMETRY PROCEDURE Ba-140 (half-life =~12.8d) decays to LA-140 (half-life ~40 hrs) and the daughter radionuclide, La-140 approaches ~ 90 % of the Ba-140 activity within~ 6 days. The La-140 photon energy at 1596 keV is used to quantify the Ba-140 activity due to its high photon emission probability yield (96%) producing a higher count rate when present and therefore, a smaller associated counting error.

Zr-95 (half-life= ~65d) decays to Nb-95 (half-life= ~35d). The photon energy of Nb-95 (~765 keV) is used to quantify Zr-95 because of the high photon emission probability yield (~100%) yielding a higher count rate and an associated lower counting error. The daughter radionuclide, Nb-95 approaches the Zr-95 activity after a time period of ~65 days, an estimated time interval occurring between sample exposure, collection and shipping, and analysis.

Panasonic identifies it as an UD-814Al TLD. The TLD has four elements, numbered 1-4. Elements and their filtration are composed of:

ELEMENT MATERIAL FILTRATION 0 0 1 Lh 84 01-Cu Thin plastic 2 CaSO4-Tm Lead 3 CaSO4-Tm Lead 4 CaSO4-Tm Lead This material has a high light output, negligible thermally induced signal loss (fading) and negligible self-dosing. The energy response curve (as will as other features) satisfies NRC Regulatory Guide 4.13. Transit doses are accounted for by use of separate TLDs.

Prior to being sent to Cooper Nuclear Station, the Mirion badges are exposed to Cs-137, to a known dose and read in the Panasonic UD-710 reader, with reference badges to establish an element response level for each badge. Badges are then re-annealed for assignment and distribution to Cooper Nuclear Station.

Following the field exposure the badges are returned to Mirion Technologies for processing in a Panasonic UD-710 reader. Each element is heated and the measured light emission is recorded. The transit controls are read in the same manner. Total exposure for each badge is the average of Elements 2, 3, and 4.

Transit Controls are calculated using the following equation:

(E31 + E41 + E32 + E42)

TRANSDOSE= 4 C-10

LOWER LIMIT of DETECTION FORMULAS The LLD formulas in Appendix C are consistent with the LLD discussion in the ODAM. The term Sb in the ODAM equals Bit by Poisson statistics, where B = blank counts and t = blank counting intervals. The decay factor term e-Mt in the ODAM is the same as the DF terms in Appendix C, but does not appear in certain analyses such as gross beta because decay does not apply. In the tritium analysis, decay is not considered because of the relatively long half-life.

Efficiencies and volumes are consistent between the two documents. Chemical yields appear in Appendix C where applicable but do not apply to other analyses such as tritium and gross beta.

SUMMARY

OF DOSES TO A MEMBER OF THE PUBLIC OFFSITE F-1

LIQUID EFFLUENT DOSE CALCULATIONS Doses to the maximum individual and Oto 50 - mile population resulting from the release of radioactive material in liquid effluents from Cooper Nuclear Station were calculated using the latest version of the LADTAP II computer program included as part ofNRCDose 2.3.20 (ORNL 2015). The LADT AP II program implements the radiological dose models of Regulatory Guide 1.109 for determining the radiation exposure to man from three principal exposure pathways in the aquatic environment -- potable water, aquatic foods, and recreational water use. Doses to both the maximum individual and Oto 50 mile population are calculated as a function of age group and pathway for significant body organs, and are presented in Tables 1 - 6.

Assumptions and data sources used for input to the LADTAP II code are described in a separate section of this appendix (see page F-67).

GASEOUS EFFLUENT DOSE CALCULATIONS (EXCEPT CARBON-14)

Doses to the maximum individual and Oto 50 mile population resulting from the release of radioactive material in gaseous effluents from the Cooper Nuclear Station were calculated using the latest version of the GASPAR computer code included as part ofNRCDose 2.3.20 (ORNL 2015). Four sites were selected for individual dose calculations: the site boundary, the nearest residence, the nearest garden and the nearest cow. GASP AR implements the radiological dose models of Regulatory Guide 1.109 for determining the radiation exposure to man from four principal atmospheric exposure pathways: plume, ground, inhalation, and ingestion. Doses to the maximum individual and the population are calculated as a function of age group and pathway for significant body organs.

Tables 1 through 7 present maximum individual doses. Population doses are given in Tables 8 through 14.

Assumptions and data used for input to the GASP AR code are described in a separate section of this appendix (see page F-67).

CARBON-14 GASEOUS EFFLUENT DOSE CALCULATIONS Doses to the maximum individual resulting from the release of Carbon-14 in gaseous effluents from the Cooper Nuclear Station (CNS) were calculated using the latest version of the GASP AR computer code included as part ofNRCDose 2.3.20 (ORNL 2015). Four pathways were selected for individual dose calculations: the nearest site boundary for inhalation, nearest garden for vegetation ingestion, nearest animal for meat ingestion, and the nearest milk animal (cow).

Based on the 2020 Land Use Census, there are no meat or milk animals identified within 5 miles of CNS. However, CNS maintains a virtual cow receptor at 3 .5 miles north-northwest of the plant and conservatively includes this receptor in dose calculations.

Use of a normalized Carbon-14 source term and scaling factors based on the annual thermal gigawatts (GWT) power generation were utilized to determine the quantity of Carbon-14 in the CNS gaseous effluent discharge for 2020. Specifically, the Boiling Water Reactor proxy production rate of 5 .1 curies Carbon-14 per G WT generation using the methodology described in EPRI, 2010 was the basis for the CNS total calculated emissions of 11.0 curies of Carbon-14 in 2020.

GASP AR implements the radiological dose models of Regulatory Guide 1.109 for determining the radiation exposure to man from four principal atmospheric exposure pathways: plume, ground, inhalation, and ingestion. Doses to the maximum individual are calculated as a function of age group and pathway for significant body organs.

Tables 15 through 21 present maximum individual doses. Note that the inhalation pathway was calculated at the closest site boundary receptor and was negligible for Carbon-14 and is not included in the tables. In addition, the doses presented were conservatively calculated based on the annual site X/Qs. These X/Qs result in doses approximately 20% higher than those calculated with the X/Qs based on growing season meteorology.

Additional assumptions and data used for input to the GASP AR code are described in a separate section of this appendix (see page F67).

DOSE CALCULATION MODELS To evaluate the radiological consequences of the routine release of liquid and gaseous effluents from the Cooper Nuclear Station, the latest versions of two computer codes were used: LADTAP II for liquid doses and GASPAR for gaseous doses included as part of NRCDose 2.3.20 (ORNL 2015). Both of these computer codes implement the dose calculational methodologies of U.S. NRC Regulatory Guide 1.109, Revision 1.

Source terms for each quarter are combined with station-specific demographic data and either hydrological dilution factors, for liquid dose calculations, or atmospheric diffusion estimates, for gaseous dose calculations.

For liquid dose calculations, the hydrological dilution factors used for input to LADTAP II, as well as other input parameters, are listed in Table 22. Other inputs not specifically listed in this table are taken from Regulatory Guide 1.109, Revision 1. Semiannual doses are obtained by summing the contributions from the appropriate quarters.

For gaseous dose calculations, atmospheric diffusion estimates are obtained from the reduction and processing of onsite meteorological data, as described in Appendix B. Source terms for the semiannual period are obtained by summing source terms for the appropriate quarters. Additional input to GASPAR includes the following station-supplied data:

0 to 50 mile population distribution 0 to 50 mile meat, milk, and vegetable distributions Absolute humidity at Cooper Nuclear Station (14.61 g/m 3)

The fraction of the year that the vegetables are grown (0.5)

The fraction of the daily feed intake derived from pasture for milk and meat animals (0.5)

Other values used for input to GASPAR are default values from Regulatory Guide 1.109, Rev. 1.

SECTION I. INTRODUCTION 5 H-5

I. INTRODUCTION This report contains a complete tabulation of data for non-ODAM required sampling stations collected during the period January 1 through December 31, 2020 by Teledyne Brown Engineering - Environmental Services.

In assessing all the data gathered for this report, it was concluded that the operation of CNS had no adverse radiological impact on the environment.

SECTION II.

SUMMARY

7 H-7

II. Summary Data from the radiological analyses of environmental media collected during 2020 for non-ODAM required stations are tabulated and discussed below.

Radiological analyses of environmental media characteristically approach and frequently fall below the detection limits of state-of-the-art measurement methods. The "less than" values in the data tables were calculated from each specific analysis and are dependent on sample size, detector efficiency, length of counting time, chemical yield (when appropriate) and the radioactive decay factor from time of counting to time of collection. Teledyne Brown Engineering meets the Lower Limit of Detection (LLD) requirements given in Table 2 of the USNRC Branch Technical Position, Radiological Monitoring Acceptable Program (November 1979, Revision 1).

SECTION III. RESULTS and Discussion of 2020 Analytical Results 9 H-9

III. Results and Discussion of 2020 Analytical Results A. Airborne Particulates Gross beta activity was observed in 19 of the 19 samples collected during 2020.

The average concentration was 0.023 pCi/m3 with a range of 0.011 to 0.032 pCi/m3

The results of the gross beta activities are presented in Table B-1. The gross beta activities for 2020 were comparable to levels measured in the previous several years. Prior to that period the gross beta activities were higher due to atmospheric nuclear weapons testing performed in other countries. The preoperational period of 1971 through 1974 averaged 0.098 pCi/m3 gross beta.

Air particulate filters were collected weekly and composited by locations on a quarterly basis, unless otherwise specified in Table B-1. They were analyzed by gamma ray spectroscopy. Beryllium-7 was observed in all of the composites. The average concentration was 0.136 pCi/m3 with a range of 0.099 to 0.173 pCi/m3 .

The results are presented in Table B-2. All other gamma emitters were below the detection limits.

B. Airborne Iodine Charcoal cartridges used to collect airborne iodine were collected weekly and analyzed by gamma spectrometry for iodine-131. The results are presented in Table B-1. All results are below the lower limit of detection.
