SEMIANNUAL EFFLUENT AND WASTE DISPOSAL REPORT i

July - December,1992 Virgil C. Summer Nuclear Station l

South Carolina Electric & Gas i

l i

i 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.

l This report satisfies the requirements in Sections 6.9.1.8 and 6.14.2 of Technical l

Specifications. Section 1.6.2 of the Offsite Dose Calculation Manual (ODCM), and 10CFRSO.36(a). Also included is an assessment of radiation doses from plant releases.

I A brief discussion of the Supplemental information and Tables 2 through 6 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 1. A summary of the meteorological data for 1992 is presented in Section F and t

Tables 7 and 8. No changes were made to the Offsite Dose Calculation Manual (ODCM) during the six month period.

A.

Supplementalinformation Regulatory limits for doses and maximum permissible concentrations presented in Supplemental Information are from the Virgil C. Summer 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 l

gaseous effluents; therefore, it has been omitted.

l B.

Gaseous Efiiuents

[

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 effluent totals are given as the square root of the sum of i

squares of counting errors and flow or volume measurement errors. A i

systematic error of 15% has been added to estimate total error.

C.

Liquid Effluents i

Liquid effluents are summarized in Tables 4 and 5. Estimated total errors are i

expressed as in Section B above.

D.

Solid Waste Shipments i

Solid waste shipments are summarized in Table 6. Curie content of radioactive l

waste packages is determined by dose rates and/or analysis of samples by j

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.

RadiologicalImpact on Man Potential doses to the maximum exposed individual in the unrestricted area were calculated using measured plant gaseous effluent and meteorological data in accordance with the Offsite Dose Calculation Manual. The source term involved one (1) waste gas decay tank (WGDT) release and a continuous six Page 1

SEMIANNUAL EFFLUENT AND WASTE DISPOSAL REPORT July - December,1992 Virgil C. Summer NuclearStation South Carolina Electric & Gas 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 maximum exposed individual due to noble gases were 5.13E-3 and 1.21E-2 mrad for gamma and beta, respectively. The maximum organ dose attributed to the i

releases was 5.41E-4 mrem for the six month period. Cumulative annual doses were 2.60E-2 mrad, 6.62E-2 mrad and 4.20E-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 130 Waste Monitor Tank batch releases,15.4 days of Steam Generator Blowdown release and continuous 1

Turbine Building Sump release.

Doses are summarized in Table 1 and total radioactivity released is described in Tables 4 and 5. The total body dose to the maximally exposed individual due to the release of radioactive liquid was 7.54E-3 mrem. The maximum organ dose was 1.12E-2 mrem to the thyroid during the six month period. Cumulative annual doses for the hypothetical maximally exposed individual were 1.83E-2 mrem and 4.13E-2 mrem for the total body and thyroid (maximum annual organ), respectively.

Dose rates and concentrations were below the limits specified in Supplemental i

information, Section 2a, b and c during all the effluent releases.

Radiation doses from radioactive effluents to members of the public due to i

their activities inside the site boundary were assessed in a manner different from that in the Offsite Dose Calculation Manual. Monthly thermoluminescent dosimetry data from eight (8) monitoring locations within the site boundary i

and ten (10) locations around the site boundary perimeter were analyzed and j

compared with respective pre-operational background and previous year i

history. Results showed that 1992 monthly dose rates did not differ i

significantly from the pre-operational or 1991 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 were calculated to be 4.63E-4 and 1.09E-3 mrad for gamma and beta, respectively. Annual cumulative doses were 2.35E-3 and 5.98E-3 mrad, respectively.

j 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 I

plants within a five (5) mile radius of Virgil C. Summer Nuclear Station.

Meteorology The meteorology data for 1992 is summarized in Table 7 by quarter. The data are shown as joint frequency distributions of wind direction and speed by atmospheric stability class. Table 8 3rovides the same information for those hours during which aatch releases occurred. There were no batch releases during the fourth quarter.

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 deterrnined by the primary differential temperature (61 to 10 meter).

The combined annual data recovery for wind direction, wind speed and stability was 94.2%. Primary variable recovery rates were as follows: wind direction (10m) - 97.0%, wind speed (10 m)

- 96.7%, and differential temperature (61 - 10m) - 94.9%. The wind direction (61m), wind speed (61m), end differential temperature (40 - 10m) recovery rates were 90.1%, 94.8% and 92.9 %, respectively.
