ANNUAL EFFLUENT AND WASTE DISPOSAL REPORT JANUARY - DECEMBER, 2002 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS 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 satisfies the requirements in Sections 6.9.1.8 and 6.14.2 of Technical Specifications, Section 1.6.2 of the Offsite Dose Calculation Manual (ODCM), and 10CFR50.36(a). Also included is an assessment of radiation doses from plant releases.

A brief discussion of the Supplemental Information and Tables I through 5 is presented in Sections A through D. An evaluation of the radiological impact on man due to operation of the Virgil C. Summer Nuclear Station is presented in Section E and Table 6. There were no abnormal releases for the period. A summary of the meteorological data for 2002 is presented in Section G and Tables 7 and 8. There were no changes made to the Offsite Dose Calculation Manual (ODCM) during the 12-month period.Section I gives a summary of oil incineration during the year.

A. Supplemental Information Regulatory limits for doses, dose rate and effluent concentration limits presented in Supplemental Information are from the Virgil C. Summer Nuclear Station ODCM and 40 CFR 190. Average energy (E5 is not applicable to the method for determining release rate limits for fission and activation gaseous effluents; therefore, it has been omitted.

B. Gaseous Effluents Gaseous effluents released from ground level are summarized in Tables I and 2. An elevated release pathway does not exist at Virgil C. Summer Nuclear Station. Cumulative doses are discussed in Section E.

The errors for gaseous effluent totals are given as the square root of the sum of squares of counting errors and flow or volume measurement errors. A systematic error of 15% has been added to estimate total error.

PAGE 1

ANNUAL EFFLUENT AND WASTE DISPOSAL REPORT JANUARY - DECEMBER, 2002 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS C. Liquid Effluents Liquid effluents are summarized inTables 3 and 4. Estimated total errors are expressed as in Section B above.

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 Potential doses to the maximum exposed individual in the unrestricted area were calculated using measured plant gaseous effluents and meteorological data in accordance with the Offsite Dose Calculation Manual. The source term involved two (2)waste gas decay tank (WGDT) releases, 0.9 days of 6-inch Reactor Building purge releases, 15.9 days of 36-inch Reactor Building purge releases and a continuous 12-month Main Plant vent release. Oil incineration was run for 37.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months in 2002. Doses are summarized in Table 6. The total activities released are presented in Tables 1 and 2. The highest quarterly air doses to the maximum exposed individual due to noble gases were 1.65E-05 and 1.32E-5 mrad for gamma and beta, respectively, during the second quarter. The maximum quarterly organ dose attributed to the releases was 1.04E-03 mrem for the second quarter. Cumulative annual dose was 2.68E-5 mrad, 1.72E-5 mrad and 1.04E-3 mrem for gamma, beta, and organ dose, respectively.

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 315 Waste Monitor Tank batch releases, 17 Condensate Backwash Receiver Tank batch releases, 1 NaOH batch releases, 16.7 days of Steam Generator Blowdown release and a continuous Turbine Building Sump release.

PAGE 2

ANNUAL EFFLUENT AND WASTE DISPOSAL REPORT JANUARY - DECEMBER, 2002 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS Doses are summarized in Table 6 and total radioactivity released is described in Tables 3 and 4. The highest quarterly total body dose to the maximally exposed individual due to the release of radioactive liquid was 2.16E-3 mrem during the first quarter. The highest organ dose was 2.31 E-3 mrem to the Liver for the first quarter. Cumulative annual doses for the hypothetical maximally exposed individual were 4.04E-3 mrem for the total body and 4.24E-3 mrem for the maximum annual organ (liver). The Liver was the maximum exposed organ for the first and fourth quarters and the GI-LLI for the second and third quarters.

Dose rates and concentrations were below the limits specified in Supplemental Information, Section 2a, b and c during all the effluent releases.

Radiation doses from radioactive effluents to members of the public due to their activities inside the site boundary were assessed in a manner different from that in the Offsite Dose Calculation Manual.

Quarterly thermoluminescent dosimetry data from four (4) monitoring locations within the site boundary and eight (8) locations around the site boundary perimeter were analyzed and compared with respective pre-operational background and previous year history. Results showed that 2002 quarterly dose rates did not differ significantly from the pre-operational or 2001 dose rates. 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 the 12-month period were calculated to be 1.26E-6 and 8.09E-7 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.

G. Meteorology The meteorology data for 2002 is summarized in Table 7, by quarter. The data are shown as joint frequency distributions of wind direction and speed by atmospheric stability class.

The wind direction and wind speed data used in the summary 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 83.2%. Primary variable recovery rates were as follows: wind direction (10 m) - 83.2%, wind speed (10 m) -

94.9%, and differential temperature (61 - 10 m) - 96.1%.

H. Offsite Dose Calculation Manual The Virgil C. Summer Nuclear Station (VCSNS) Offsite Dose Calculation Manual (ODCM) was not revised during the affected 12-month period.

I. Oil Incineration The incinerator operated for a period of 37.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months , burning 368 gallons of oil at 9.7 gal/hr. The incinerated oil contained concentrations of 2.38E-06 uCi/ml Co-60, 6.52E-09 uCi/mI Mn-54, 1.1 3E-06 uCi/ml Fe-55, and 2.33E-07 uCVml Cs-1 37. The dose to the maximum exposed individual from the incinerated oil was 3.88E-05 mrem.

SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS during troubleshooting to determine the cause of intermittent spiking events with the monitor. An improper resistor in the monitor's rate meter module and channel crossover interference from other modules in the same rack contributed the overall problem and required an extensive amount of trouble shooting and research to resolve.
