1. Regulatory and BFN ODCM Limits
a. Fission and Activation Gases in Gaseous Effluent:

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.

b. Iodines and Particulates with Half-Lives Greater than Eight Days in Gaseous Effluents:

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.

c. 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.

2. Limitation on Dose Rate
a. Fission and Activation Gases in Gaseous Effluent:
1. 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.
2. The BFN ODCM Section 7.2 determines the maximum noble gas release rate.

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT Supplemental Information E-4

2. Limitation on Dose Rate (Continued)
b. Iodines and Particulates with Half-Lives Greater than Eight Days in Gaseous Effluents:
1. 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.
2. The BFN ODCM Section 7.3 determines the maximum particulate and iodine dose rates.
c. Liquid Effluents:
1. 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
2. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 Ci per milliliter (ml) total activity.
3. 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.

4. Measurements and Approximations of Total Radioactivity
a. Fission and activation gases:
1. 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.
2. The tritium concentration is determined by the analysis of a monthly grab sample for each release point.
b. Iodines and Particulates:
1. 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.
2. 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.
c. Liquid effluents:
1. 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.

6. Abnormal Releases (Continued)

Summary of Abnormal/Unplanned Releases The release of radioactive material to the environment from BFN has been a small fraction of the 10 CFR 20 Appendix B and 10 CFR 50 Appendix I limits. There were no limits exceeded as specified in 10 CFR 20 Appendix B and 10 CFR 50 Appendix I.

Four abnormal liquid releases occurred in 2016.

1.

Three of the abnormal releases were from the U1, U2, and U3 Station Sumps.

These releases occurred throughout 2016 and were the result of several identified sources including multiple steam leaks which occurred in the U-1, U-2 and U-3 Steam Jet Air Ejector Rooms along with the U-1 and U-2 Recombiner Rooms and U-2 Moisture Separator Room.

(CRs 1205661, 1206175, 1207246, 1240249, 1240570, 1255845, 1250531)

2.

During a walkdown of the Reactor Bldg roof, a leak coming from the U-2B Turbine Building exhaust (2-FAN-064-0047B) was discovered. This leak was coming from the warped expansion joints around the exhaust duct and falling onto the Reactor Bldg roof. (CR 1241503)

7. Missed Compensatory Samples During the reporting period, January 1, 2016 through December 31, 2016, there was one missed compensatory sample.

CR 1194524 was flagged as a potential for a missed ODCM required compensatory sample.

Review of the CR and the identified surveillance, 0-SI-4.8.A.1-1 (Liquid Effluent Permit) performance, determined a procedure violation occurred with the incorrect attachment completed by Operations personnel. Performance of the wrong attachment during the release resulted in the requirements of ODCM, Table 1.1-1, Action E for 0-FIC-77-60, Radwaste Discharge Flow Loop when inoperable not being met for that release.

The completion of the correct attachment would have satisfied the ODCM requirement in Table 1.1-1, instrument 4, Action E stated below.

With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may be continued provided the flow rate is estimated at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> during actual releases. Pump curves may be used to estimate flow.

During the final review of this surveillance, calculations were performed, utilizing the data collected and the correct attachment, which subsequently verified the operability of the 0-FIC-77-60.

8. Changes to the Radwaste System and Changes to the Process Control Program In calendar year 2016, BFN had no permanent changes to the Radwaste System or the Process Control Program.
9. Revisions to the Offsite Dose Calculation Manual (ODCM)

During 2016 there were no revisions made to the Offsite Dose Calculation Manual (ODCM).

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-27

1. 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.
2. 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 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-28

2. Dose Limits (Continued)

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.

3. 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 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 4, 5, and 6.

4. 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.

a. Airborne Release Points There are four monitored release points from BFN: the turbine building, the radwaste building, the reactor building, and the stack.

Releases from the turbine building are considered ground-level releases. The ground-level Joint Frequency Distribution (JFD) is derived from wind speeds and directions measured 10.5 meters above the ground and from the vertical temperature difference between 10.03 and 45.30 meters, and are presented for each quarter in the 2016 Meteorological Data Tables 7A, 7B, 7C, and 7D.

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-29

4. Doses From Airborne Effluents (Continued)
a. Airborne Release Points (Continued)

Releases from the radwaste and reactor buildings are considered split-level releases.

Portions of the release are treated as ground-level while other portions are considered elevated depending on the ratio of the vertical exit velocity to the horizontal wind speed.

The split-level dispersion approach is implemented using a model that requires two complete quarterly JFDs for each effluent vent, one for the ground-level releases and one for the elevated releases. The ground-level portion of the split-level JFD is based on wind speeds and directions measured 10.5 meters above ground-level and from the vertical temperature difference between 10.03 and 45.30 meters. The elevated portion of the split-level JFD is based on wind speeds and direction measurements at the 45.74 meter level and the vertical temperature difference between 10.03 and 89.59 meters. Both of these JFDs are given for each quarter in the 2016 Meteorological Data Tables 8A, 8B, 8C, and 8D.

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 2016 Meteorological Data Tables 9A, 9B, 9C, 9D.

b. Meteorological Data 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.

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.

4. Doses From Airborne Effluents (Continued)
c. External Exposure Dose 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.
d. Submersion Dose 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.
e. Organ Dose 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 4.

5. 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.

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-31

5. Doses From Liquid Effluents (Continued)

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.

a. Liquid Release Points and River Data 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 plant's 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 of his 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 plant's release point. Doses calculated for the maximum exposed individual due to liquid effluents for each quarter in the period are presented in Table 5 along with the average river flows past the plant site for the periods.

6. 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 4 and 5.

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-32

7. Offsite Direct Radiation Dose External gamma radiation levels were measured by environmental dosimeters deployed around BFN as part of the offsite Radiological Environmental Monitoring Program (REMP).

The quarterly gamma radiation levels determined from these dosimeters during this reporting period averaged approximately 18 mrem/quarter at onsite (at or near the site boundary) stations and approximately 15 mrem/quarter at offsite stations or approximately 2.5 mrem/quarter higher onsite than at offsite stations. This difference is consistent with levels measured for pre-operation and construction phases of the Tennessee Valley Authority nuclear plants where the average radiation levels onsite were generally 2-6 mrem/quarter higher than the levels offsite. This may be attributable to natural variations in environmental radiation levels, earth moving activities onsite, the mass of concrete employed in the construction of the plants, or other undetermined influences.

Fluctuations in natural background dose rates and in dosimeter readings tend to mask any small increments which may be due to plant operations. Thus, there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents.

8. 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 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 onsite. It consisted of gamma dose from the plume, ground contamination, and from equipment sources (i.e., tanks, turbine shine, radioactive material storage areas, etc.). The critical location was determined to be an Optically Stimulated Luminescence (OSL) dosimeter near the Livewell Center (Training Center). The direct radiation dose accounting for background and occupancy was approximately 0.75 mrem/quarter during 2016.

The total annual dose commitment to a member of the public for 2016 was 3 mrem. It can be concluded that the dose limit for a member of the public at the site boundary as specified in 10 CFR 20.1301 was not exceeded.

9. 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

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT RADIOLOGICAL IMPACT E-33

9. Total Dose (continued) 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 6.

In order to evaluate the need for implementation of this additional analysis, the drinking water pathway dose from I-131 to the maximum organ and age group was calculated. There was no drinking water pathway dose from I-131 and the performance of the I-131 specific analysis is not required for BFN REMP drinking water samples.

The ODCM requires the exertion of best efforts to return inoperable instruments to operable status within 30 days. Failure to return such instruments to an operable status within the prescribed interval requires a description in the Annual Radioactive Effluent Release Report.

During the reporting period, January 1, 2016 through December 31, 2016,there were five radiological instruments inoperable for greater than 30 days.

The 0-RM-90-130 radioactive liquid effluent monitor was inoperable from July 23, 2015 to April 1, 2016.This was due to Background radiation counts for BFN-0-RM-090-0130 being elevated (~2800 counts/sec) while in process preventing BFN-0-RM-090-0130 from being placed in service. It appeared that the elevated background was from an actual fixed background from within the containment chamber section of the process. WO 117211266 was initiated to disassemble the piping to perform cleaning of the containment chamber. Following the cleaning, minimal to no change in background counts were noted thus the work order is to replace the containment chamber and required associated flanged piping. Additional cleaning was performed (flushes) and a new monitor was also installed and calibrated (CR 110179)

The 0-RM-90-147/148 was declared inoperable on 2/10/2016 due to Stack Gas Rad Monitor CH1 and CH2 indicating low counts (9 counts and 10 counts respectfully). Operations entered LCOT# 0-090-ODCM-2016-0008. Monitor was declared operable on 4/20/2016. (CR 1135716)

The 0-FIC-77-60 Radwaste Discharge Valve Flow Loop was inoperable on 3/24/2016 during performance of 0-SI-4.8.A.1-1, Liquid Effluent Permit, due to the average flow rate being outside the plus or minus 8% of flow rate calculated based on tank volume change over time,(ODCM Table 2.1-1.d Channel Functional Test).

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT Groundwater Protection Program E-170 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 (BFN). The groundwater wells described in this section are not part of the Radiological Environmental Monitoring Program (REMP).

Onsite groundwater monitoring was performed in 2016. 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 26 groundwater wells located in the Protected Area (PA) and the Owner Controlled Area (OCA) during 2016, with normal sampling frequencies quarterly and semiannually. Some wells were sampled monthly as certain criteria were met or for investigation purposes. Samples are routinely analyzed for environmental levels of tritium (H-3) and principle 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 onsite storm drains, catch basins and surface water.

In the early 2000s, BFN initiated a groundwater study to identify the source low levels of detected tritium onsite. Results from the groundwater study, completed in June 2006, suggest the source of tritiated groundwater were from historical leaks and spills associated with Radwaste/Condensate transfer tunnel. Groundwater and surface water level measurement 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.

One event occurred in 2016 which required voluntary notification per NEI 07-07, Industry Groundwater Protection Initiative (Condition Report 1183798). The notification was prompted when two onsite groundwater wells, MW-01 and MW-08, exceeded the Environmental Protection Agency (EPA) drinking water value of 20,000 pCi/L (picocuries per liter) tritium (Condition Reports 1164659, 1183737). During the investigation of MW-01 exceeding the EPA limit, a leak within the Unit 2 Turbine Building Steam tunnel was found to be the apparent source. Following investigation, it was found that the leak from the Steam tunnel reached groundwater through degraded expansion joints within the tunnel room. BFN made an entry into the tunnel at full power to remove blockage from a floor drain which was allowing contaminated water to pool on the floor and reach the degraded expansion joints. The highest concentration well identified for year 2016 was MW-01 which resulted in 36,444 pCi/L of tritium.

The leak occurred underneath the turbine building in which followed a preferential flow path to the East and West sides of the plant. MW-01 is located on the West side of the plant and MW 08 is located on the East side of the plant. Since the initial spike of 36,444 pCi/L tritium in March 2016 for MW-01 and MW-08 tritium concentration of 22,400 pCi/L, the tritium concentration values have trended back down considerably. The site monitored MW-01, MW 08 and other groundwater wells down gradient of the leak on an increased frequency following the discovery of the leak. The leak within the U2 Turbine Building Steam Tunnel was

BROWNS FERRY NUCLEAR PLANT UNITS 1, 2, AND 3 2016 Annual Radioactive EFFLUENT Release REPORT Groundwater Protection Program E-171 repaired in Spring 2017 during the Unit 2 Refueling Outage. The expansion joints, floor drains, and floor coatings were inspected during the Spring 2017 outage. The expansion joints in the tunnel were repaired by applying a coating atop the joint to keep future water from exiting the joints.

Groundwater sample results that were taken in support of the GPI for 2016 are listed in the tables below. Low levels of tritium were detected in the monitoring wells listed below. No other nuclides, other than tritium, were detected in any groundwater well, surface water, catch basin, or storm drain in 2016.
