VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS radioactivity released is described in Tables 4 and 5. The highest quarterly total body dose to the maxirnai:y exposed individual due to the release of radioactive liquid was 5.15E-3 mrem during the second quarter. The highest organ dose was 3.68E-2 mrem to bone for the second quarter. Cumulative annual doses for the hypothetical maximally exposed individual were 9.96E-3 mrem and 3.79E-2 mrem !
for the total body and bone (maximum annual organ), respectively.
The liver was the maximum exposed organ for the first quarter. The j bone was the maximum exposed organ for the second quarter and ;
the gastro-intestinal tract / lower large intestine (GI-LLI) was the maximum exposed organ for the third and fourth quarters of 1996.
Dose rates and concentrations were below the limits specified in Supplemental Information, Section 2a, b and c during all the effluent i releases. l Radiation doses from radioactive effluents to members of the public Q
O due to 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 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 i
showed that 1996 monthly dose rates did not differ significantly from tr pre-operational or 1995 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 monih period were calculated to be 6.88E-6 and 1.72E-5 mrad for gamma and beta, reyectively.
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.

LJ JANUARY - DECEMBER,1996 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS F. Abnormal Releases During the year the plant had one abnormal gaseous release from the l Reactor Building Purge Exhaust. The purge valve was inadvertently l opened for approximately thirty minutes. Due to the short release duration and low reactor building activity, an insignificant amount of
- radioactive material was released. The conservative release estimate was 1.01E-3 Ci. giving a total body dose of 9.33E-7 mrem and a maximum organ dose of 2.35E-7 mrem.
G. Meteorology The meteorology data for 1996 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 provides the same information for those hours during which batch releases occurred.
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 i 10 meter).
The combined annual data recovery for wind direction, wind speed and stability was 93.5%. Primary variable recovery rates were as )
follows: wind direction (10 m) - 93.8%, wind speed (10 m) - 93.5%, l and differential temperature (61 - 10 m)- 94.2%.
H. Offsite Dose Calculation Manual ;
The Virgil C. Summer Nuclear Station (VCSNS) Offsite Dose Calculation Manual (ODCM) was revised twice during the affected 12 month period.
Revision 21 changed Section 1 (Specification of Controls) and Section 2 (Liquid Effluent) to conform with the associated approved Technical Specification changes from 1995. The revision also provided for the replacement of MPC values in liquid effluents with ECL values consiste ct l with 10 CFR Part 20, Appendix B, Table 2, Column 2. Specific changes i are summarized in Attachment I, prior to the copy of the ODCM. Revision 22 clarified the sampling requirements for the NaOH Spray Tank when
, activities require draining of NaOH from the tank or sight glass. The PAGE 5 l

i revision also allowed for emptying NaOH directly to the Neutralization Basin for release through Circulating Water. Revision 22 of the ODCM is presented in Attachment II.
- l. OIL INCINERATION Gaseous releases from oil incineration were minimal during 1996. !
The incinerator operated for a period of 234.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, buming 802 l gallons of oil at 3.42 gal /hr. The inci.nerated oil contained Co-60, Mn-l 54 and tritium at concentrations of a 69E-8,6.52E-9, and 1.35E-5 ;
uCi/mi, respectively. The annual organ dose from the incinerated oil was 3.40-5 mrem.

ANNUAL EFFLUENT AND WASTE DISPOSAL REPORT JANUARY - DECEMBER,1996 l VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS F. Abnormal Releases During the year the plant had one abnormal gaseous release from the ;
- Reactor Building Purge Exhaust. The purge valve was inadvertently i opened for approximately thirty minutes. Due to the short release duration and low reactor building activity, an insignificant amount of ;
radioactive material was released. The conservative release estimate l was 1.01E-3 Cl. giving a total body dose of 9.33E-7 mrem and a maximum organ dose of 2.35E-7 mrem.
G. Meteorology The meteorology data for 1996 is summarized in Table 7 by quarter. l The data are shown as joint frequency distributions of wind direction !
and speed by atmospheric stability class. Table 8 provides the same i information for those hours during which batch releases occurred.
l I
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). :
l The combined annual data recovery for wind direction, wind speed and stability was 93.5%. Primary variable recovery rates were as r follows: wind direction (10 m)- 93.8%, wind speed (10 m)- 93.5%, t and differential temperature (61 - 10 m) - 94.2%. l l
H. Offsite Dose Calculation Manual l!
The Virgil C. Summer Nuclear Station (VCSNS) Offsite Dose Calculation i Manual (ODCM) was revised twice during the affected 12 month period. !
Revision 21 changed Section 1 (Specification of Controls) and Section2 l (Liquid Effluent) to conform with the associated approved Technical ;
Specification changes from 1995. The revision, also, provided for the !
!- replacement of MPC values in liquid effluents with ECL values consistent ;
with 10 CFR Part 20, Appendix B, Table 2, Column 2. Revision 22 clarified ;
the sampling requirements for the NaOH Spray Tank when activities . i require draining of NaOH from the tank or sight glass. The revision also i
allowed for emptying NaOH directly to the Neutralization Basin for release l through Circulating Water. 5 l
