Supplemental Information Brunswick Steam Electric Plant Units 1 & 2 Period 1/1/2016 - 12/31/2016 Page 2-3 Carbon-14 In Regulatory Guide 1.21, Revision 2, Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste, the NRC recommends U.S. nuclear power plants evaluate whether C-14 is a "principal radionuclide" in gaseous effluents, and if so, report the amount of C-14 released. Improvements over the years in effluent management practices and fuel performance have resulted in a decrease in gaseous radionuclide (non-C-14) concentrations, and a change in the distribution of gaseous radionuclides released to the environment. As a result, many sites show C-14 has become a "principal radionuclide" for the gaseous effluent pathway, as defined in Regulatory Guide 1.21, Rev. 2. Although committed to Regulatory Guide 1.21, Rev. 1, the Brunswick Steam Electric Plant 2016 ARERR contains estimates of C-14 radioactivity released in 2016, and estimates of public dose resulting from the C-14 effluent.

Because the dose contribution of C-14 from liquid radioactive waste is much less than that contributed by gaseous radioactive waste, evaluation of C-14 in liquid radioactive waste is not required (Ref. Reg. Guide 1.21, Rev. 2). The quantity of gaseous C-14 released to the environment can be estimated by use of a C-14 source term scaling factor based on power generation (Ref. Reg. Guide 1.21, Rev. 2). The Brunswick Steam Electric Plant Updated Final Safety Analysis Report (UFSAR) states the C-14 release rate from a BWR is approximately 9.5 Ci/yr per unit assuming 80%

plant capacity factor, or 292 Effective Full Power Days (EFPD). Since Brunswick Steam Electric Plant has two reactors, the total release rate would be 19.0 Ci/yr. This value was scaled using actual EFPD of 319.70 for Unit 1 and 361.28 for Unit 2 in 2016 to give a total release rate of 2.22E+01 Ci/yr.

Public dose estimates from airborne C-14 are performed using dose models in Regulatory Guide 1.109. The dose models and assumptions used are documented in the Brunswick Steam Electric Plant ODCM 3.3.3, Carbon-14. The estimated C-14 dose impact on the maximum organ dose from airborne effluents released from Brunswick Steam Electric Plant in 2016 is well below the 10CFR50, Appendix I, ALARA design objective (i.e., 15 mrem/yr per unit).

Based on the 2016 Land Use Census, the critical receptor is located in the south sector at 1.7 miles with a garden.

There are no meat or milk pathways within 5 miles. Regulatory Guide 1.109 methodology was used to determine the dose to this critical receptor. The bone dose for 2016 was 2.04E+00 mrem and the total body dose was 4.09E-01 mrem.

Outfall Number 004 discharges to the discharge canal which is a designated release point. The BSEP sewage decant is sampled monthly for gamma and tritium analysis. On December 11, 2013 the monthly effluent sample contained tritium, there was no detectable gamma activity. Condition Report (CR) 651320 was generated and daily sampling was initiated for effluent accountability. Inputs to the system were sampled and it was discovered that tritiated groundwater is leaking into the Number 6 lift station. The source of tritium is from pre-existing groundwater contamination in the general area surrounding the Number 6 lift station. Regulatory Affairs confirmed this was not reportable per NEI 07-07 groundwater reporting. Approximately 1.29E+06 gallons containing 4.62E-02 curies of tritium was released in 2016 to the discharge canal.

Discussion of liquid releases from the Storm Drain Collector Basin (SDCB)

During periods of heavy rain, the contents of the SDCB may be released to the discharge canal in accordance with regulatory requirements to protect plant personnel and equipment. The SDCB was released directly to the discharge canal on 21 occasions in 2016 due to heavy rains. Approximately 6.74E+06 gallons containing 3.55E-01 curies of tritium were released. There was no detectable gamma radioactivity.

Discussion of liquid releases from the Storm Drain Stabilization Pond (SDSP) Infiltration On August 22, 2014 water was found flowing from the Storm Drain Stabilization Facility (SDSF) outfall pipe into the intake canal when a permitted release was not in progress. The water was analyzed and found to contain tritium.

Condition Report 704775 was generated and daily sampling was initiated for effluent accountability. Subsequent investigation determined the water was infiltrating through the side of the first collection box in the drainage line located near the SDSP discharge weir. The pipe was repaired by installing a fiberglass liner inside the existing outfall pipe and sealing the original pipe/liner interface. This repair was completed in 2015. No releases from this pathway occurred in 2016 due to the successful repair.

Discussion of liquid releases from the Storm Drain Stabilization Facility (SDSF)

The SDSF collects rainwater, water from miscellaneous low volume drains on plant site, water from the Groundwater Extraction System, and water from the Unit 1 CST Remediation Facility. Treatment consists of filtration and evaporation. When sufficient water has accumulated in the pond it is released into the intake canal where it is drawn into the plant circulating and service water system and eventually released into the discharge canal. There were 14 SDSF releases in 2016. Approximately 8.95E+07 gallons containing 5.33E+00 curies of tritium were released from the SDSF. There was no detectable gamma radioactivity.

Discussion of water evaporation from the Storm Drain Stabilization Pond (SDSP)

It was calculated that 5.96E+07 gallons of tritiated water was released via evaporation from the SDSP in 2016. This yields 2.19E-01 curies of tritium released to the atmosphere as a ground release. The nearest resident to the pond is in the northwest sector at approximately 0.3 miles. The maximum exposed individuals at that location received a calculated dose of 6.70E-05 mrem via the inhalation pathway in 2016. Only inhalation dose was determined because the exposed individuals do not have a garden and also do not have any milk or meat animals at this location.

Supplemental Information Brunswick Steam Electric Plant Units 1 & 2 Period 1/1/2016 - 12/31/2016 Page 2-5 Discussion of water evaporation from the Storm Drain Stabilization Facility (SDSF)

It was calculated that 4.93E+06 gallons of tritiated water was released via evaporation from the SDSF in 2016. This yields 3.68E-01 curies of tritium released to the atmosphere as a ground release. The nearest resident to the pond is in the north northwest sector at approximately 0.5 miles. The maximum exposed individuals at that location received a calculated dose of 2.37E-04 mrem via the inhalation pathway in 2016. Only inhalation dose was determined because the exposed individuals do not have a garden and also do not have any milk or meat animals at this location.

Discussion of liquid releases from the Marsh to Nancys Creek Samples are routinely analyzed from the marsh areas that drain into Nancys Creek during falling tides. The marsh areas are all on company owned property. The marsh land is under the influence of high and low tides and releases to Nancys Creek, which is offsite. This constitutes a release point for evaluation. The sampling program consists of weekly sampling and analysis at eight locations. All gamma analyses performed in 2016 were less than the Lower Limit of Detection (LLD). Some tritium analyses were greater than the LLD. The average tritium concentration each month, two high tides per day, the area of the marsh at high tide, the days in the month, and a conservative factor of 2 were used to calculated the amount of tritium released each month. In 2016, it was calculated that 5.39E+07 gallons were released to Nancys Creek containing 1.81E-01 curies of tritium. This yielded a Total Body dose of 2.20E-03 mrem to an adult from eating fish and invertebrate (shrimp, crabs, etc.).

Discussion of liquid releases from the Storm Drain Stabilization Pond (SDSP)

The SDSP collects rainwater as its only input source. Treatment from this location consists of sedimentation, evaporation, and transpiration. When sufficient water has accumulated in the pond, it is released into the intake canal where it is drawn into the circulating and service water system and eventually released into the discharge canal.

There were 7 SDSP releases in 2016. Approximately 4.49E+07 gallons were released in 2016 containing 0.00E+00 curies of tritium. There was no detectable gamma radioactivity.

The fuel cycle dose assessment for Brunswick Steam Electric Plant includes liquid and gaseous effluent dose contributions from Brunswick Steam Electric Plant and direct and air-scatter dose from the onsite ISFSI and Turbine Buildings. No other uranium fuel cycle facility contributes significantly to the maximum exposed individual. Also included is dose from Carbon-14, evaporation of tritium from both the SDSP and SDSF, and marsh releases containing tritium to Nancys Creek (Ref. Attachment 2, Supplemental Information, of this report for further information). The combined dose to a maximum exposed individual from effluent releases and direct and air-scatter dose is below 40 CFR Part 190 limits as shown by the following summary.

Note: The 40 CFR Part 190 effluent dose analysis to the maximum exposed individual from liquid and gas releases does not include the dose from noble gases (i.e., total body and skin) due to the low significance compared to other dose pathways.

The maximum dose rate to the nearest real individual from the ISFSI and Turbine Buildings is conservatively calculated to be less than 14.8 mrem/yr. The below excerpt from plant operating manual 0PLP-36, 10 CFR 72.212 Report, revision 4, Attachment 1, is provided to document the method used to calculate the dose from the onsite ISFSI and Turbine Buildings as less than 14.8 mrem/yr to the nearest real individual.

5.2.2 Dose from Normal Operations and Anticipated Occurrences

4. Radiation from Plant Operations Offsite direct dose measurements are obtained and analyzed in accordance with the Radiological Environmental Monitoring Program (REMP) and submitted annually to the NRC. As part of the REMP, two rings of stations are established for monitoring direction radiation. The inner ring of stations is established in the general area of the site boundary. The outer ring of stations is located at distances of 8 km or greater from the site (Ref. [7.5.16]). Environmental data on external radiation exposure does not indicate a significant higher exposure rate for the inner ring versus the outer ring. This demonstrates that no discernible off-site exposure occurs as a result of plant operations (Ref. [7.6.2], [7.6.3]).

For conservatism, an approach is taken for quantifying the plant contribution to direct dose at the controlled area boundary. The ODCM TLD sample point along either the inner or outer ring of stations with the highest dose reading for each quarter was used as a bounding indicator dose.

The real dose contribution from direct radiation sources during plant operations at BSEP it taken at 14.8 mrem/year.

Dose contributions from Carbon-14 in gaseous effluents have been determined from ODCM 3.3.3, Carbon-14. The maximum dose rate to the nearest real individual from the release of Carbon-14 in gaseous effluents is conservatively calculated to be less than 2.04E+00 mrem/yr based on 2.22E+01 Curies released in 2016 (Ref. Attachment 2, Supplemental Information, of this report).

Dose contributions from evaporation of the Storm Drain Stabilization Pond (SDSP) have been determined from ODCM 3.3.2, I-131, I-133, Particulates, and Tritium, equation 3.2-19. The maximum dose rate to the nearest real individual from evaporation of tritium in the SDSP is conservatively calculated to be less than 6.70E-05 mrem/yr based on 2.19E-01 Curies released in 2016 (Ref. Attachment 2, Supplemental Information, of this report).

Dose contributions from evaporation of the Storm Drain Stabilization Facility (SDSF) have been determined from ODCM 3.3.2, I-131, I-133, Particulates, and Tritium, equation 3.2-19. The maximum dose rate to the nearest real individual from evaporation of tritium in the SDSF is conservatively calculated to be less than 2.37E-04 mrem/yr based on 3.68E-01 Curies released in 2016 (Ref. Attachment 2, Supplemental Information, of this report).

Dose contributions from marsh releases to Nancys Creek from ODCM 2.1.5, Marsh Releases. The maximum dose rate to the nearest real individual from marsh releases to Nancys Creek is conservatively calculated to be less than 2.20E-03 mrem/yr based on 1.81E-01 Curies released in 2016 (Ref. Attachment 2, Supplemental Information, of this report).

Total dose from liquid and gaseous effluents from Brunswick Steam Electric Plant and the additional pathways mentioned above is conservatively estimated to be less than 17 mrem/yr for total body and organ. It is recognized summing dose for different organs and age groups is not entirely accurate. However, the sum of the organ and age specific doses will always be less than the sum of the maximums of each. Therefore, summing the maximum values of each provides the most conservative value to ensure compliance with 40 CFR 190. The dose from all pathways related to operation of Brunswick Steam Electric Plant meets the 40 CFR Part 190 requirements of an annual dose commitment to any member of the general public of less than 25 mrem total body or any organ and 75 mrem to the thyroid.

Information to Support the NEI Ground Water Protection Initiative Brunswick Steam Electric Plant Units 1 & 2 Period 1/1/2016 - 12/31/2016 Page 7-2 The Brunswick Steam Electric Plant groundwater sampling and analysis program is a significant surveillance program.

Wells are installed around the Storm Drain Stabilization Pond (SDSP), in the Protected Area (PA), and throughout the Owner Controlled Area (OCA). The wells listed in the ODCM are collected as part of the Radiological Environmental Monitoring Program (REMP) and reported in the Annual Radiological Environmental Operating Report (AREOR). The monitoring wells not described in the ODCM are listed below. The list consists of shallow and intermediate wells in different locations around the OCA and PA. They are used to evaluate groundwater movement and for remediation of the Unit 1 Condensate Storage Tank (CST) leak and the SDSP.

Unit 1 CST Groundwater Wells - The investigation into groundwater impacts resulting from the December 2010 Unit 1 Condensate Storage Tank line leak resulted in the installation of numerous monitoring/recovery wells. Two of these wells (U1CSTREM-07BCH and U1CSTREM-09BCH) are installed in the Castle Hayne aquifer (greater than 70

' below ground surface) to investigate and monitor potential impacts to the aquifer. Ten of these wells (U1CSTREM-05, U1CSTREM-02B, U1CSTREM-08/GWM-17, U1CSTREM-09B, U1CSTREM-15/GWM-15, U1CSTREM-21B, U1CSTREM-22B, U1CSTREM-27B, MW-01B, and MWPA-111B/GWM-01) are installed in the dense sand unit (45 70

' below ground surface) to investigate and monitor impacts to this flow zone comprised of native material beneath the plant excavation backfill. Three of these dense sand wells are currently being used as recovery wells as part of the groundwater remediation effort (GWM-01, GWM-15, GWM-17). Twenty-four of these wells (U1CSTREM-02C/GWM-01, U1CSTREM-09C, U1CSTREM-10/GWM-04, U1CSTREM-11, U1CSTREM-12, U1CSTREM-13/GWM-13, U1CSTREM-14/GWM-15, U1CSTREM-16/GWM-16, U1CSTREM-18/GWM-18, U1CSTREM-19/GWM-19, U1CSTREM-21C, U1CSTREM-22C/GWM-07, U1CSTREM-23/GWM-11, U1CSTREM-24/GWM-22, U1CSTREM-25/GWM-21, U1CSTREM-26/GWM-06, U1CSTREM-27C/GWM-05, U1CSTREM-28/GWM-03, U1CSTREM-29/GWM-02, U1CSTREM-30/GWM-08, U1CSTREM-31/GWM-09, U1CSTREM-32, U1CSTREM-33/GWM-10, and MWPA-112C/GWM-12) are installed in the plant excavation backfill (up to 45

' below ground surface) to investigate and monitor impacts to this flow zone where the leak occurred. Fifteen of these wells are currently used as recovery wells as part of the groundwater remediation effort.

Wells are typically sampled quarterly or semi-annually. Ground water samples are regularly analyzed for tritium and all wells are analyzed for gamma emitters. No gamma emitters, other than naturally occurring radionuclides, were identified in well samples during 2016.

Results from sampling during 2016 are shown in the table below.

No events meeting the criteria for voluntary notification per NEI 07-07, Industry Ground Water Protection Initiative, occurred at Brunswick Steam Electric Plant in 2016.
