Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report I. Introduction II. Supplemental Information A. Regulatory Limits

1. Gaseous Effluents Fission and Activation Gases The release of fission and activation gases is regulated by the dose limits of Title 10 of the Code of Federal Regulations (10 CFR) 50 Appendix I and Browns Ferry Nuclear Plant (BFN) Offsite Dose Calculation Manual (ODCM). The air dose to areas at and beyond the site boundary due to noble gases released in gaseous effluents per unit shall be limited during any calendar quarter to 5 millirad (mrad) for gamma radiation and 10 mrad for beta radiation; and during any calendar year to 10 mrad for gamma radiation and 20 mrad for beta radiation.

Iodines and Particulates with Half-Lives Greater than Eight Days The release of iodines and particulates in gaseous effluent is regulated by the dose limits of 10 CFR 50 Appendix I and the BFN ODCM. The dose to a member of the public from radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases with half-lives greater than eight days in gaseous effluent released per unit to areas at and beyond the site boundary shall be limited to any organ during any calendar quarter to 7.5 millirem (mrem), and during any calendar year to 15 mrem.

2. Liquid Effluents The release of radioactive liquid effluents is regulated by the dose limits of 10 CFR 50 Appendix I and the BFN ODCM. The doses or dose commitment to a member of the public from radioactive materials in liquid effluents released from each unit to unrestricted areas shall be limited during any calendar quarter to 1.5 mrem to the total body and 5 mrem to any organ and during any calendar year to 3 mrem to the total body and 10 mrem to any organ.

B. Limitation on Dose Rate

1. Gaseous Effluents Fission and Activation Gases The instantaneous release rate of fission and activation gases is based on the dose rate limits of 10 CFR 20.1301 and the BFN ODCM. The dose rate at any time to areas at and beyond the site boundary due to noble gases released in gaseous effluents from the site shall be limited to 500 mrem per year to the total body and 3000 mrem per year to the skin.

The BFN ODCM Section 7.2 determines the maximum noble gas release rate.

Page 4 of 162

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Iodines and Particulates with Half-Lives Greater than Eight Days The instantaneous release rate of particulates and iodines is regulated by the dose rate limits of the BFN ODCM. The dose rate at any time to areas at and beyond the site boundary, due to I-131, I-133, H-3, and particulates with half-lives greater than eight days in gaseous effluent released from the site, shall be limited to 1500 mrem per year to any organ.

The BFN ODCM Section 7.3 determines the maximum particulate and iodine dose rates.

2. Liquid Effluents The concentration of radionuclides in liquid effluents released at any time from the site to unrestricted areas shall be limited to the concentrations specified in 10 CFR 20.1001-20.2402, Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases.

For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 Ci per milliliter (ml) total activity.

C. Average Energy The BFN ODCM limits the 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 use of dose rate is in accordance with NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants."

Since the release rate is not used for effluent control, the average beta and gamma energies (E) for gaseous effluents discussed 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," are not applicable and not included in this report.

D. Measurements & Approximations of Total Radioactivity Radioactivity measurements performed in support of the Browns Ferry Nuclear Plant ODCM meet the Lower Limit of Detection requirements given in ODCM Tables 2.2-1 and 2.2-2.

1. Gaseous Effluents Noble gases in the building vent and stack (elevated) gaseous effluents are continuously monitored. The flow rate of the stack is continuously monitored and the building vent effluent flow rates are calculated once a shift based on the configuration of operating exhaust fans. The vent flow is calculated for each release. Gas grab samples of the stack are taken and analyzed weekly. Gas grab samples of in-service vents are taken and analyzed monthly. The specific noble gas activity concentrations and total volume of the gases are used to calculate the total Curies of noble gases released.

In 2019, Browns Ferry revised noble gas sampling and analysis procedures which included sampling with a larger volume (1240 cc gas Marinelli) and analyzing for a longer count time (1000 seconds). Since this revision, the site has detected low levels of noble gases in the stack vent, which is expected.

Page 5 of 162

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report The tritium concentration is determined by the analysis of a monthly grab sample for each release point.

Iodines and particulates are continuously sampled on impregnated charcoal filters and particulate filters, respectively. The charcoal and particulate samples are replaced at least weekly and analyzed to determine specific activity concentrations. The specific activity concentrations and vent flow rate data are used weekly to verify that release rate limits were not exceeded. The specific activity concentrations and total volume of gaseous effluent are used on a monthly basis to determine the total curies of each particulate and iodine released during the month.

The gross alpha concentration is determined by analysis of a monthly particulate filter composite sample, and strontium-89 and strontium-90 are determined by analysis of a quarterly particulate filter composite sample for each release point.

Carbon-14 (C-14) production and gaseous waste effluent activity source term estimates were based on methodology provided in EPRI 1021106, Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents, December 2010. C-14 gaseous activity and dose calculations are made using the following assumptions: (1) continuous release of the estimated C-14 generated for each unit during power operation based on the number of Effective Fuel Power Days (EFPD) for the period, (2) maximum C-14 activity from literature values cited in EPRI Report 1021106, and (3) typical fraction as carbon dioxide for gaseous releases from literature values also cited in EPRI Report 1021106.

In 2019, Browns Ferry updated C-14 production rate estimates utilizing the proxy methodology provided in EPRI Report 1021106. TVA documented this update in Updated Carbon-14 Production Rate Estimates for Gaseous Releases at TVA NPG Sites, October 2019. The C-14 releases increased in 2019 due to all three units completing Extended Power Uprate (EPU). The EPU for each unit increased the units MWth (Megawatt thermal) from 3,458 to 3,952 MWth. This increase in MWth is used in the calculation of C-14 releases. The increase in C-14 releases is expected.

2. Liquid Effluents The gamma ray emitting radionuclide concentrations are determined for each batch by gamma ray spectroscopy analysis of a grab sample. The allowable release rate is calculated for each batch based upon the known dilution flow. The flow rate of the liquid effluent is continuously monitored and the total volume released in each batch is determined. The total gamma activity released in each batch is determined by multiplying the radionuclide concentrations by the total volume discharged. The total gamma activity released during the month is then determined by summing the gamma activity content of each batch discharged during the month.

The gross alpha and tritium concentrations are measured on a monthly composite sample. The strontium-89, strontium-90, and iron-55 are measured on a quarterly composite sample.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report F. Abnormal Releases

1. Gaseous Abnormal gaseous tritium releases occurred in 2022 from the Auxiliary Boiler System when the boilers were in service for unit outages. The identified source of tritium to the auxiliary boiler system is main steam leak-by from degraded Steam Jet Air Ejector (SJAE) / Auxiliary Boiler valves to the auxiliary boiler header (CR 1508177). At the Beginning of 2022, these valves were scheduled to be replaced during each units respective outage, with Unit 2 valves to be completed in Spring 2023.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report M. Groundwater Monitoring and Program (NEI 07-07)

In 2007, the Nuclear Energy Institute (NEI) established the Groundwater Protection Initiative (GPI), NEI 07-07. The Groundwater Protection Initiative was established to 1) improve management of situations involving inadvertent radiological releases that get into groundwater and 2) to improve communication with external stakeholders to enhance trust and confidence on the part of local communities, States, the NRC, and the public in the nuclear industrys commitment to a high standard of public radiation safety and protection of the environment. This section provides information and sample results from on-site groundwater locations that were sampled in support of the Groundwater Protection Initiative at Browns Ferry Nuclear Plant. The groundwater wells described in this section are not part of the Radiological Environmental Monitoring Program (REMP).

In the early 2000s, BFN initiated a groundwater study to identify the source of low-level tritium detected on-site. Results from the groundwater study (Investigation of Tritium Releases to Groundwater, 2006), suggest the source of tritiated groundwater was from historical leaks and spills associated with Radwaste/Condensate transfer tunnel.

Groundwater and surface water level measurements during the study indicated the return channel and subsequently the Tennessee River will ultimately be recipient to tritiated groundwater discharge from the site. It has been determined that there are no groundwater wells onsite or within 2-miles of the site that are used as a source of drinking water.

Groundwater movement in the area has been determined to be from the plant site toward the Tennessee River.

On-site groundwater monitoring was performed in 2022. The purpose of on-site groundwater monitoring is to ensure timely detection of inadvertent radiological releases to groundwater. Non-REMP groundwater wells monitor for potential leaks from plant equipment. As part of the GPI, BFN monitored a total of 30 groundwater wells located in the protected area and the owner-controlled area during 2022. Normal sampling frequencies are quarterly and semiannually with some wells sampled monthly if certain criteria are met or for investigation purposes. Samples are routinely analyzed for environmental level tritium (H-3) and principal gamma emitters (PGE) with selected wells analyzed for Hard-to-Detect (HTD) radionuclides (Gross Alpha, Fe-55, Ni-63, Sr-89, and Sr-90). In support of the groundwater program, the site also monitors recapture and on-site storm drains, catch basins and surface water.

In 2022, low levels of tritium were detected in on-site groundwater wells as indicated in Table 10, Groundwater Data. Table 10 demonstrates all on-site groundwater wells that indicated detectable tritium concentrations. Tritium concentrations in 2022 ranged from non-detectable, less than 196 pCi/L, up to a maximum concentration of 7,100 pCi/L (MW-1).

BFN has been monitoring a legacy tritium plume in the vicinity of groundwater well Dewat-A located adjacent to the reactor building. This plume is the result of previous leaks in past years (2015 and 2016). No other plant related radionuclides were detected in any groundwater well. There were no instances of any on-site spills or leaks that occurred during 2022 reporting period that were communicated to off-site agencies or that met the criteria in NEI 07-07, Appendix A.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact VI. Radiological Impact to Man A. Introduction Potential doses to the "maximum exposed individual" and the population around Browns Ferry Nuclear Plant (BFN) are calculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM). The methodology used to estimate dose for determining plant releases for the reporting period is specified in Sections 6 and 7 of the ODCM. Dispersion of radioactive effluents in the environment is estimated using meteorological data and river flow measured during the period. In this report, the doses resulting from releases are described and compared to limits established for BFN.

B. Dose Limits The ODCM specifies limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of radioactive effluents. These limits are set well below the Technical Specification limits which govern the concentrations of radioactivity and doses permissible in unrestricted areas. This ensures that radioactive effluent releases are As Low As Reasonably Achievable.

The air dose limits in areas at and beyond the Site Boundary due to noble gases released in gaseous effluents per unit are:

  • 5 mrad per quarter and 10 mrad per year for gamma radiation.

and

  • 10 mrad per quarter and 20 mrad per year for beta radiation.

The dose limits to a member of the public in an unrestricted area from radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases with half lives > 8 days released in gaseous effluents for each unit are:

  • 7.5 mrem per quarter and 15 mrem per year to any organ.

The dose or dose commitment to a member of the public from radioactive material in liquid effluents released to unrestricted areas are:

  • 1.5 mrem per quarter and 3 mrem per year to the total body, and
  • 5 mrem per quarter and 10 mrem per year to any organ.

The limit for the total effective dose equivalent to an individual member of the public inside the site boundary is:

  • 100 mrem per year.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact The Environmental Protection Agency limits for total dose to any member of the public in the vicinity of a nuclear power plant, established in the Environmental Dose Standard of 40 CFR 190, are:

  • 25 mrem per year to the whole body, 75 mrem per year to the thyroid, and
  • 25 mrem per year to any other organ.

C. Dose Calculations Estimated doses to members of the public are determined using computer models (the Gaseous Effluent Licensing Code, and the Quarterly Water Dose Assessment Code (QWATA)).

These models are based on guidance provided by the Nuclear Regulatory Commission (NRC) for determining the potential dose to individuals and populations living in the vicinity of the plant. The area around the plant is analyzed to determine the pathways through which the public may receive a dose. The doses calculated are a representation of the dose to a "maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maximum values to ensure conservative reporting of data. The values chosen will tend to overestimate the dose. The expected dose to actual individuals is lower.

The calculated doses are presented in Tables 3, 4, and 5.

D. Doses from Airborne Effluents For airborne effluents, members of the public can be exposed to radiation from several sources: direct radiation from the radioactivity in the air, direct radiation from radioactivity deposited on the ground, inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited from the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation and subsequently consumed by animals.

Releases from the stack are considered to be elevated releases. The JFDs for elevated releases are based on wind directions and wind speeds measured at 90.29 meters and the vertical temperature difference between 10.03 and 89.59 meters, and are given for each quarter in the 2022 Meteorological Data Tables.

Meteorological variables at BFN are measured continuously. Measurements collected include wind speed and wind direction at heights of 10.5, 45.74, and 90.29 meters above the ground, and temperature at heights of 10.03, 45.30, and 89.59 meters above the ground.

Quarterly JFDs are calculated for each release point using the appropriate levels of meteorological data. A quarterly JFD gives the percentage of the time that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a given stability class A through G. The wind speeds are divided into nine wind speed ranges.

Calms are distributed by direction in proportion to the distribution of noncalm wind directions less than 1.6 m/s (3.5 mph). Stability classes are determined from the vertical temperature difference between two measurement levels.

Page 28 of 162

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact The generally open terrain around BFN does not cause any significant effects on the transport and dispersion of gaseous effluents from the plant. Within 30 kilometers of BFN, the terrain is mostly gently rolling hills (30-60 meters). Between 30 and 80 kilometers, the hills become larger to the north and south and mountainous to the east and northeast. The Tennessee River/Wheeler Lake may have a minor effect on transport and dispersion in the immediate vicinity of BFN during periods of winds with a southerly component, overcast skies, and relatively high wind speeds. Also, the lower layer (10-45 meters) stability class tends to be more stable. However, during this infrequent condition, dose estimates will be conservative.

Dose calculated for maximum external air dose (gamma-air and beta-air) are made for points at and beyond the unrestricted area boundary as described in the BFN ODCM. The highest of these doses is then selected.

External doses to the skin and total body, due to submersion in a cloud of noble gases, are calculated for the nearest residence in each sector. The residence with the highest dose is then selected from all sectors.

Dose to an organ due to releases of airborne effluents are estimated for the inhalation, ground contamination, and ingestion pathways. The ingestion pathway is further divided into three possible contributing pathways: ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables. Doses from applicable pathways are calculated for each receptor location identified in the most recent land use survey. To determine the maximum organ dose, the doses from the pathways are summed for each receptor. However, for the ingestion dose, only those pathways that exist for each receptor are considered in the sum, e.g., milk ingestion doses are included only for locations where milk was consumed without commercial preparation and vegetable ingestion is included only for those locations where a garden was identified. To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest unrestricted area boundary location is added to each identified receptor. For ground contamination, the dose added to the organ dose being calculated is the total body dose calculated for that location, i.e., it is assumed that the dose to an individual organ is equal to the total body dose.

The maximum organ dose, thyroid dose, and total body dose from airborne effluents are presented in Table 3.

E. Doses from Liquid Effluents For liquid effluents, the public can be exposed to radiation from three sources: the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactive material deposited on the river shoreline sediment (recreation). The concentration of radionuclides in the Tennessee River is calculated by a computer model which uses measured hydraulic data downstream of BFN.

Parameters used to determine the doses are based on guidance given by the NRC for maximum ingestion rates, exposure times, etc.

Page 29 of 162

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact Wherever possible, parameters used in the dose calculation are site specific. The models that are used to estimate doses, as well as the parameters input to the models, are described in detail in the BFN ODCM.

Radionuclide concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous. When necessary, liquid releases from BFN, located at Tennessee River Mile 294, are made through diffusers which extend into the Tennessee River. It is assumed that releases to the river through these diffusers will initially be entrained in one-fifth of the water which flows past the plant. The QWATA code makes the assumption that this mixing condition holds true until the water is completely mixed at the first downstream dam (Wheeler Dam), at Tennessee River Mile 283.

Doses are calculated for locations within a 50 mile radius downstream of the plant site.

The maximum potential recreation dose is calculated for a location immediately downstream from the plants release point. The maximum exposed individual dose from ingestion of fish is assumed to be that calculated for the consumption of fish caught anywhere between the plant and the first downstream dam. The maximum exposed individual dose from drinking water is assumed to be that calculated at the nearest downstream public water supply [West Morgan - East Lawrence (WMEL)]. This could be interpreted as indicating that the maximum exposed individual, as assumed for liquid releases from BFN, is an individual who obtains all drinking water at WMEL, consumes fish caught from the Tennessee River between BFN and Wheeler Dam, and spends 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per year on the shoreline just downstream of the plants release point. Doses calculated for the maximum exposed individual due to liquid effluents for each quarter in the period are presented in Table 4 along with the average river flows past the plant site for the periods.

F. Population Doses Population doses due to airborne effluents are calculated for people living within a 50-mile radius of the plant site. Doses from external pathways and inhalation are based on the 50-mile human population distribution. Ingestion population doses are calculated assuming that each individual consumed milk, vegetables, and meat produced within the sector in which the individual resides.

Population doses due to liquid effluents are calculated for the entire downstream Tennessee River population. Water ingestion population doses are calculated using actual population figures for downstream public water supplies. Fish ingestion population doses are calculated assuming that all sport fish caught in the Tennessee River are consumed by the Tennessee River population. Recreation population doses are calculated using historical recreational data on the number of shoreline visits at downstream locations.

Population doses calculated for airborne and liquid effluents are presented in Tables 3 and 4.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact G. Offsite Direct Radiation Dose External gamma radiation levels were measured by environmental dosimeters deployed around BFN as part of the 2022 Radiological Environmental Monitoring Program (REMP). The 2022 environmental dosimeters were evaluated in accordance with the guidance provided in ANSI N13.37-2014. The process of this evaluation is summarized: 1) The average field dosimeter results is determined for each location and normalized to a standard quarter of 91 days, 2) The field results is adjusted by the transit and shield (storage) dose to determine the net dose at each location; this is performed at each location for each quarter, and the four quarters are summed to determine the annual net dose, 3) The quarterly and annual historical average net dose was determined for each monitoring location, based on data from 2017-2021, 4) The standard deviation of each historical net dose was calculated, to determine the 90th percentile standard deviation for both the quarterly and annual results,

5) the 2022 quarterly and annual net dose are compared to the historical averages (plus 3 times the 90th percentile standard deviation, also known as the minimum differential dose) to determine if any facility related dose was identified at any location during any quarter or the year.

The monitoring locations are grouped according to the distance from the plant. The onsite group consists of dosimeters within 2 miles of the plant. The offsite group consists of all locations greater than 2 miles from the plant. This difference in onsite and offsite averages is consistent with levels measured for preoperational and construction phases at BFN where the average radiation levels onsite were generally 2-6 mrem/quarter higher than the levels offsite. This may be attributed to natural variations in environmental radiation levels, earth moving activities onsite, the mass of concrete employed in the construction of the plant, or other undermined influences. In order to implement the methodology of ANSI N13.37-2014, the dose received by dosimeters in shielded storage that are used as unexposed controls was determined. This in turn was used to account for extraneous dose that should be removed from the gross measurements as measured by field dosimeters.

The result of the evaluation of environmental dosimeters is that there was no facility related dose measured in the environment around Browns Ferry. There were no quarterly or annual dosimeters that exceed the historical baseline plus the calculated minimum differential dose.

H. Dose to a Member of the Public Inside the Site Boundary Pursuant to ODCM Section 7.7.5, a review was performed to determine the highest dose to a hypothetical member of the public in the site boundary. The dose to a member of the public consists of the sum of dose commitments from effluent releases as well as any direct radiation dose. The gaseous effluent dose commitment is negligible compared to the direct radiation dose.

The direct radiation dose was determined from area environmental dosimeters located on-site. The critical location was determined to be an Optically Stimulated Luminescence (OSL) dosimeter near the Livewell Center (SE-1). The Annual baseline is 79 mrem/yr with the 2022 Annual dose of 77.8. The direct radiation dose at the Livewell Center, accounting for background and occupancy, was determined to be non-detectable as this location did not exceed the historical baseline plus the calculated minimum differential dose.

Browns Ferry Nuclear Plant Units 1, 2 and 3 2022 Annual Radioactive Effluent Release Report Radiological Impact I. Total Dose To determine compliance with 40 CFR 190, annual total dose contributions to the maximum exposed individual from BFN radioactive effluents and all other nearby uranium fuel cycle sources are considered.

The annual dose to any organ other than the thyroid for the maximum exposed individual is conservatively calculated by summing the following doses: the total body air submersion dose for each quarter, the critical organ dose (for any organ other than the thyroid) from airborne effluents for each quarter from ground contamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, the maximum organ dose (for any organ other than the thyroid) from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the REMP. This dose is compared to the 40 CFR 190 limit for total body or any organ dose (other than the thyroid) to determine compliance.

The annual thyroid dose to the maximum exposed individual is conservatively estimated by summing the following doses: the total body air submersion dose for each quarter, the thyroid dose from airborne effluents for each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the REMP. This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance.

Total dose from the fuel cycle is presented in Table 5.
