, SEMIANNUAL EFFLUENT AND WASTE DISPOSAL REPORT January June,1991 Virgil C. Summer Nuclear Station South Carolina Electric & Gas This report is being submitted as a summary of the 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 6.9.1.9 of Technical Specifications and 10CFR50.36(a). Also included is an assessment of radiation doses from plant releases.

A brief discussion of the Supplemental Information and Tables 2 through 6 is presented in Sections A through D. An evaluation of the radiologicalimpact on man due to operation of the Virgil C. Summer Nuclear Station is presented in Section E and Table 1. Changes made to previous reports are presented in Section F and Appendix 1.

A. SupplementalInformation Regulatory limits for doses and maximum permissible concentrations prescrited in Supplemental Information are from the Virgil C. Sumnier Nuclear Station Technical Specifications and 40 CFR 190. Average energy (E)is not applicable to the method for determining release rate limits for fission and activation gaseous ef fluents; therefore,it has been omitted.

B. Gaseous Ef fluents Gaseous effluents released from ground level are summarized in Tables 2 and

3. An elevated release pathway does not exist at Virgil C. Summer Nuclear Station. Cumulative doses are discussed in Section E.

The errors for gaseous ef fluent 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.

C. Liquid Effluents Liquid effluents are summarized in Tables 4 and 5. Estimated total errors are expressed as in Section B above.

D. Solid Waste Shipments Solid waste shipments are summarized in Table 6. Curie content of radioactive waste packages is determined by dose rates and/or analysis of samples by gamma spectroscopy. 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 maxirnum exposed individual in the unrestricted area were calculated using measured plant gaseous effluent and meteorological data in accordance with the Offsite Dose Calculation Manual. Included in the source term was one (1) waste gas decay tank (WGDT) batch release and a continuous six month main plant vent release. Doses are summarized in Table

1. The total activities released are presented in Tables 2 and 3. Air doses to the Page 1 1

4 SEMIANNUAL EFFLUENT AND WASTE DISPOSAL REPORT .

J:nuary - June,1991 Virgil C. Summer Nuclear Station South Carolina Electric & Gas maximum exposed-individual due to noble gases were 5.19E-3 and 1.28E-2 mrad for gamma and beta, respectively. The maximum organ dose attributed to the releases was 3.73E-3 mrom for the six month period 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 227 Waste Monitor Tank batch releases and continuous Turbine Building Sump and Steam Generator Blowdown releases. Doses are summarized in Table 1. The total radioactivity

  • released is described in Tables 4 and 5. The total body dose to the maximally exposed mdividual due to the radioactive liquid released was 4,49E-2 mrem.

The maximum organ dose was 5.83E 2 mrem to the thyroid.

SEMIANNUAL EFFLUENT AND WASTE DISPOSAL REPORT January - June,1991 Virgil v iummer Nuclear Station South Carolina Electric & Gas Dose rates and concentrations were below the limits snecified in Supplemental information, Section 2a, b and c during all the of fluent releases.

Radiation doses from radioactive effluents to workers at the Fairfield Hydro Station were calculated to be 7,12E-4 and 1.76E-3 mrad for gamma and beta, respectively.

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

Technical Specifications, Section 3/4.11.4, page B 3/411-6 establishes a five (5) mile limit beyond no uranium which fuel cycle doses plants from within nearby a five (plants

5) mile radiusare insignificant.

of Virgil There are C. Summer Nuclear Station.

F. Changes to Previous Reports During the affected six month period, a problem was found with computer software determinations of airborne tritium concentrations. A detailed description of the problem is given in LER 91-004, August 1991. Attachment i gives the corrected airborne tritium concentrations and affected doses for previous reports. The increases in maximum exposed organ doses due to tritium in gaseous ef fluents were 2.09E 3, 9.04E-3, 5.00E-5,1.78E-2, 4.94E-2, 3.50E-3 and 7.50E-4 mrem, respectively for 1984 through 1990. The maximum increase of 4.94E-2 mrem in 1988 led to a change in the percent of annual limit from 2,18E-1% to 5.47E-1%. Thus, the overall organ dose effect from the

tritium problem was minimal, i

l An additional correction to the last report (July - December,1990) also needs to be made. One (1) shipment of five (5) irradiated fuel pins was trucked in September,1990 to Chalk River, Canada for testing. Part B of Table 5 needs to be updated accordingly.
