ANNUAL EFFLUENT RADIOACTIVE RELEASE REPORT JANUARY - DECEMBER, 2007 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 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 2007 is presented in Section G and Tables 7 and 8. Section H gives a summary of two 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 to support a Combined Operating License Application.

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.

PAGE 1

ANNUAL EFFLUENT RADIOACTIVE RELEASE REPORT JANUARY- DECEMBER, 2007 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, 0.1 days of 6-inch Reactor Building purge releases, no 36-inch Reactor Building purge releases and a continuous 12-month Main Plant vent release. Oil incineration for 74.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> in

.2007. 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 2.84E-04 mrad for gamma and 3.64E-4 mrad for beta during the fourth quarter.

The maximum quarterly organ dose attributed to the releases was 2.31 E-03 mrem for the first quarter. Cumulative annual dose was 3.98E-04 mrad, 5.08E-4 mrad and 2.31 E-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 112 Waste Monitor Tank batch releases, no Condensate Backwash Receiver Tank batch releases, 1 NaOH batch release, 10.9 days of Steam Generator Blowdown release and a continuous Turbine Building Sump release.

PAGE 2

ANNUAL EFFLUENT RADIOACTIVE RELEASE REPORT JANUARY - DECEMBER, 2007 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 5.76E-4 mrem during the third quarter. The highest organ dose was 6.39E-4 mrem to the LIVER for the first quarter.

Cumulative annual doses for the hypothetical maximally exposed individual were 1.61 E-3 mrem for the total body and 1.87E-3 mrem for the LIVER, the maximum annual organ. The LIVER was the maximum exposed organ for the first through fourth 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 2007 quarterly dose rates did not differ significantly from the pre-operational or 2006 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 1.87E-5 and 2.39E-5 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.

ANNUAL EFFLUENT RADIOACTIVE RELEASE REPORT JANUARY - DECEMBER, 2007 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS F. Abnormal Releases During 2007, the plant had no abnormal releases.

G. Meteorology The meteorology data for 2007 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 100%. Primary variable recovery rates were as follows: wind direction (10 m) - 100%, wind speed (110 m) - 100%,

and differential temperature (61 - 10 m) - 100%.

H. Offsite Dose Calculation Manual The Virgil C. Summer Nuclear Station ODCM was revised on January 9, 2007 and September 18, 2007.

Revision 25 implemented the recommendations of the NEI Industry Groundwater Protection Initiative. This increased the number of groundwater monitoring wells and defined reporting criteria for actual or potential groundwater contamination events.

The LLDs for Noble Gas in Gaseous Effluents and Ce-144 in Liquid Effluents were changed to comply with NUREG 1301.

Revision 26 established annual reporting requirements for major changes to radioactive waste treatment system due to the elimination of the Monthly Operating Report in Technical Specification Amendment 175. Modified the NEI Industry Groundwater Protection Initiative reporting requirements to conform to NEI 07-07 issued August 31, 2007.

Additionally corrections were made for formatting, grammatical and typographical errors in both revisions.

Oil Incineration The incinerator operated for a period of 74.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, burning 357 gallons of oil at the average rate of 4.8 gal/hr. The incinerated oil contained concentrations of 6.83E-09 uCi/ml for Mn-54, 4.59E-08 uCi/ml for Co-60, 6.93E-9 uCi/ml for Cs-1 34 and 1.49E-08 uCi/ml for Cs-1 37. The dose to the maximum exposed individual from the incinerated oil was 1.29E-06 mrem.

J. Offsite Dose Calculation Manual Reportable Incidences There were no ODCM Reportable Incidences in 2007.

K. Supplemental Groundwater Monitoring The station is preparing a Combined Operating License Application for two new units. Thirty-one groundwater monitoring wells were installed to support this application. Sampling of seven wells for chemical and radiological analysis began in July of 2007. Tritium was identified in a single well located 1.03 miles SSW of the existing unit at a level of 2.26E+03 pCi/l.

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. Additional investigation and sampling is ongoing.
