ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2008 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 Technical Specifications Section 6.9.1.8, Offsite Dose Calculation Manual (ODCM) Sectionl.6.2 and 10CFR50.36(a). Also included is an assessment of radiation doses from plant releases.

A brief discussion of the Supplemental Information and Tables 1 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 2008 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. There were no ODCM Reportable Incidences.

Section K gives the status of Supplemental Groundwater Monitoring.

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 (E-bar) 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 1 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.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2008 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS C. Liquid Effluents Liquid effluents are summarized in Tables 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 no Waste Gas Decay Tank (WGDT) releases, 5.6 days of 6-inch Reactor Building purge releases, 34.6 days of 36-inch Reactor Building purge releases and a continuous 12-month Main Plant vent release. Oil incineration for 194.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> in 2008. 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 2.39E-04 mrad for gamma during the second quarter and 2.78E-4 mrad for beta during the fourth quarter. The maximum quarterly organ dose attributed to the releases was 2.17E-03 mrem for the second quarter. Cumulative annual dose was 4.31 E-04 mrad, 5.04E-4 mrad and 2.17E-03 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 222 Waste Monitor Tank batch releases, 24 Condensate Backwash Receiver Tank batch releases, 1 NaOH batch release, 23.2 days of Steam Generator Blowdown release and a continuous Turbine Building Sump release.

PAGE 2

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2008 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS Doses are summarized in Table 6 and total radioactivity released is described in Tables 1 and 3. The highest quarterly total body dose to the maximally exposed individual due to the release of radioactive liquid was 5.40E-3 mrem during the first quarter. The highest organ dose was 5.51 E-3 mrem to the LIVER for the first quarter.

Cumulative annual doses for the hypothetical maximally exposed individual were 7.58E-3 mrem for the total body and 7.76E-3 mrem for the LIVER, the maximum annual organ. The LIVER was the maximum exposed organ for the first and fourth quarters and the GI-LLI was the maximum exposed organ 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 using liquid and gaseous effluents along with meteorological data.

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 the 2008 quarterly dose rates did not differ significantly from the pre-operational or 2007 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 2.03E-5 and 2.37E-5 mrad for gamma and beta, respectively.

Radiation doses from nearby uranium fuel cycle sources were not assessed. The ODKM, 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.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2008 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS F. Abnormal Releases During 2008, the plant had no abnormal releases.

G. Meteorology The meteorology data for 2008 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 99.7%. Primary variable recovery rates were as follows: wind direction (10 m) - 99.7%, wind speed (10 m) - 99.7%,

and differential temperature (61 - 10 m) - 99.7%.

H. Offsite Dose Calculation Manual The Virgil C. Summer Nuclear Station ODCM was not revised in 2008.

Oil Incineration The incinerator operated for a period of 194.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />, burning 1099 gallons of oil at the average rate of 5.64 gal/hr. The incinerated oil contained concentrations of 1.65E-08 uCi/mI for Co-60, 1.38E-8 uCi/mI for Cs-1 34 and 1.07E-08 uCi/mI for Cs-1 37.

The dose to the maximum exposed individual from the incinerated oil was 1.96E-06 mrem.

J. Offsite Dose Calculation Manual Reportable Incidences There were no ODCM Reportable Incidences in 2008.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2008 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS K. Supplemental Groundwater Monitoring New Plant Site The station was preparing a Combined Operating License Application for two new units. Groundwater monitoring wells were installed to support this application. Limited sampling of these wells for chemical and radiological analysis began in July of 2007. Tritium was identified in a single well location 1.03 miles SSW of the existing unit at a maximum concentration of 2.88E+03 pCi/l. A single sample from a paired adjacent deep well indicated 5.19E+02 pCi/I.

Condensate Polisher resin was disposed of in this area in 1994 under a 10 CFR 20.302(a) application approved by South Carolina Department of Health and Environmental Control. This is the suspected cause of the groundwater contamination.

Sixteen additional wells in the surrounding area were sampled with no activation or fission products identified above Minimum Detectable Activity (MDA) when analyzed to the Environmental Lower Limits of Detection (LLD).

Unit 1 Dewaterinq System The station has experienced issues with groundwater intrusion in to plant buildings and structures. In 2008, a modification was implemented to install fourteen dewatering wells. Soil and water samples were collected and analyzed during the drilling of these wells.

Groundwater samples were collected prior to and following each incremental pump down of these wells.

No activation or fission products above MDA were identified when analyzed to the Environmental LLD.
