ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER 2018 VIRGIL C. SUMMER NUCLEAR STATION Introduction This report is being submitted as a summary of quantities of radioactive liquid and gaseous effluents and solid waste released from the Virgil C. Summer Nuclear Station. This report is submitted in fulfillment of the requirements in the V. C. Summer Nuclear Station Operating License Technical Specifications Section 6.9.1.8, Offsite Dose Calculation Manual (ODCM) Section1 .6.2 and 10CFR50.36(a) and follows the reporting details specified in USN RC Regulatory Guide 1.21 <1).

Summary information of radioactive gaseous and liquid effluents is presented along with a summary of radioactive waste disposal as well as an evaluation of the radiological impact on man due to operation of the Virgil C. Summer Nuclear Station. Supplemental information including release limits also required by USNRC Regulatory Guide 1.21 is provided as Appendix A A. Supplemental Information Regulatory limits for doses, dose rate and effluent concentration limits presented in Supplemental Information arEi.._from the Virgil C. Summer Nuclear Station ODCM and 40 CFR 190. Average energy ( E ) is not applicable to the method for determining release rate limits for fission and activation gaseous effluents, therefore, it has been omitted. A compilation of required supplemental information is provided in Appendix A B. Gaseous Effluents Gaseous effluents released from ground level are summarized in Tables 1 and 2. An elevated release pathway does not exist at Virgil C. Summer Nuclear Station. Cumulative doses are discussed in Section E.

The total error for all liquid and gaseous pathways except gaseous particulate and iodine is estimated as twenty percent. Total error for gaseous particulate and iodine is estimated as twenty five percent. Error was derived using root sum of squares methodology considering known sources of error including calibration of detectors and flow measurement equipment, sample preparation, and analysis counting error.

C. Liquid Effluents Liquid effluents are summarized in Tables 3 and 4. Estimated total errors are expressed as in Section B above.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER 2018 VIRGIL C. SUMMER NUCLEAR STATION D. Solid Waste Shipments Solid waste shipments are summarized in Table 5. Curie content of radioactive waste packages is determined by dose rates and/or gamma spectroscopy analysis of samples.

The total error for each type of curie content determination is conservatively estimated to be the sum of a 15% systematic error and a 20% photon response error for the detector used.

E. Radiological Impact on Man Dose to the maximum exposed individual in the unrestricted area was calculated using measured plant gaseous effluents and meteorological data in accordance with the Offsite .

Dose Calculation Manual. The source term involved 1 Waste Gas Decay Tank (WGDT) release, 13.23 days of 6-inch Reactor Building purge releases, 18.57 days of 36-inch Reactor Building purge releases and a continuous 12-month Main Plant vent release.

Doses are summarized in Table 6. The total gaseous activities released are presented in Tables 1 and 2. The highest quarterly air doses at the station boundary resulting from the release of noble gases were 2.80E-04 mrad for gamma during the fourth quarter and 2.16E-04 mrad for beta during the fourth quarter. The maximum quarterly organ dose attributed to the releases, excluding Carbon-14, was 3.1*8E-03 mrem. Cumulative annual dose was 4.50E-04 mrad, 2.76E-04 mrad and 3.39E-03 mrem for gamma, beta, and organ dose, respectively. Discussion of the impact of Carbon-14 is included in Section K.

Measured plant liquid effluent data was used to calculate estimates of doses to individuals in accordance with the Offsite Dose Calculation Manual. The source term consisted of the isotopic contents of 241 Waste Monitor Tank batch releases, 14 Condensate Backwash Receiver Tank batch releases, 1 NaOH Sump batch release, 2.17 days of Steam

• Generator Slowdown release and a continuous Turbine Building Sump release.

Doses are summarized in Table 6 and total liquid radioactivity released is described in Tables 3 and 4. The highest quarterly total body dose to the maximum exposed individual resulting from the release of radioactive liquid was 2.39E-03 mrem during the third quarter.

The highest organ dose was 2.40E-03 mrem to the GI-LLI for the third quarter. Cumulative annual doses for the hypothetical maximum exposed individual were 7.55E-03 mrem for the total body and 7.73E-3 mrem for the GI-LLI, the maximum annual organ. The Liver was the maximum exposed organ for the first quarter and the GI-LLI was maximum exposed organ for the last three quarters.

Dose rates and concentrations were below station limits as specified in Supplemental Information,Section II A, B, and C during all the effluent releases.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER 2018 VIRGIL C. SUMMER NUCLEAR STATION Radiation exposure to members of the public within the site boundary was assessed through calculation of gamma and beta air dose at 0.25 miles of the gaseous effluent release point and direct measurement of exposure using thermoluminescent dosimeters.

Onsite air dose for this reporting period was 1.47E-03 mrad gamma and 8.99E-05 mrad beta, well below levels that can be distinguished above background. Quarterly thermoluminescent dosimetry (TLD) data from four onsite monitoring locations within 0.2 miles of the Reactor Building and eight locations at the site boundary were analyzed and compared with respective pre-operational background and previous year history. Results showed that the 2018 quarterly dose rates did not differ significantly from the pre-operational or 2017 dose rates.

The impact of lhdependent Spent Fuel Storage Installation (ISFSI) operation which began cask storage on March 26, 2016 was assessed using six TLD locations monitoring the perimeter of the ISFSI site. The TLD locations were monitored for three quarters prior to fuel storage and continued to be monitored through 2018 during which fuel storage casks were stored. Analysis of monitoring results showed no statistically significant increase in perimeter dose as a result of ISFSI operation.

Based on review of gaseous effluent dose calculations and analysis of onsite TLD monitoring it was concluded that doses to members of the public inside the site boundary were indistinguishable from normal background dose.

Radiation doses from radioactive effluents to workers at the Fairfield Hydro Station for this reporting period were calculated to be 2.13E-05 and 1.31 E-05 mrad for gamma and beta, respectively.

Radiation doses from radioactive effluents to workers at the New Nuclear Site for this reporting period were calculated to be 1.83E-04 and 1.21 E-04 mrad for gamma and beta, respectively.

Radiation doses from nearby uranium fuel cycle sources were not assessed. The ODCM, Sections 1.3.1 and B/1.3 establish a five (5) mile limit beyond which doses from nearby plants are insignificant. There are no uranium fuel cycle plants within a five (5) mile radius of Virgil C. Summer Nuclear Station.

F. Abnormal Releases None

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER 2018 VIRGIL C. SUMMER NUCLEAR STATION G. Meteorology The meteorological data for 2018 was collected and analyzed. A summary report of joint frequency distributions of wind direction and speed by atmospheric stability class for each quarter is included as Enclosure A along with an annual summary and summary of conditions during a gaseous batch release.

I The wind direction and wind speed data used were acquired from the 10-meter level of the primary monitoring tower. Stability was determined by the primary differential temperature (61 to 10 meter).

The combined annual data recovery for wind direction, wind speed and stability was 97.47%. Primary variable recovery rates were as follows: wind direction (10 m) - 97.45%, wind speed (10 m) - 97.45%, and differential temperature (61 - 10 m) - 97.45%.

H. Offsite Dose Calculation Manual The Virgil C. Summer Nuclear Station ODCM was not revised in 2018.

I. Offsite Dose Calculation Manual Reportable Incidents There were no ODCM reportable incidents in 2018.

J. Major Changes to Radioactive Waste Treatment Systems During 2018, there were no major changes to the Radioactive Waste Treatment System.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER 2018 VIRGIL C. SUMMER NUCLEAR STATION K. Carbon-14 Gaseous Effluents Carbon-14 production and release estimates were calculated using EPRI Report 1021106(2), "Estimation of Carbon-14 in Nuclear Plant Gaseous Effluents". This calculation uses active core coolant mass, average neutron flux by energy and reactor coolant nitrogen concentrations to determine Carbon-14 generation based upon an effective full power year. The estimated generation for VG Summer Nuclear station for 2018 was 8.68 curies.

Public dose estimates were performed using Regulatory Guide 1.109 (3) methodology. Carbon dioxide is assumed to make up 20% of the Carbon-14 gaseous emissions from the station based upon available references and on-site testing. Carbon-14 is the highest dose contributor of all radionuclides released in gaseous effluents. Annual dose resulting from Carbon-14 releases in gaseous effluents is estimated to be 1.54E-01 mrem total body and 7.72E-01 mrem to the maximum organ (bone).
