Subject:
Virgil C. Summer Nuclear Station Docket No. 50-395 Operating License No. NPF-12 Fish Kill - August 22, 1989
Dear Mr. Krecker:
South Carolina Electric & Gas Company (SCE&G) herein submits a report concerning a fish kill in the Virgil C. Summer Nuclear Station (VCSNS) dischtcge bay which occurred on August 22, 1989. The enclosed report describes the current event and probable cause. Actions to be taken to investigate and. determine appropriate measures to prevent these events were provided to your office in a letter dated August 23, 1989.
In accordance with the VCSNS Operating License NPF-12, Appendix B, a copy of this report is being provided to the Nuclear Regulatory Commission.
Additionally, a copy of this report will also be provided to the South Carolina Department of Wildlife & Marine Resources per the request of Mr. H.
J. Logan, Chief of Fisheries.
Should you require any further information, please contact Mr. Charles McKinney of my staff at your convenience.
Very truly yours,

FISH Kil1 REPORT August 22,1989 On August 22, 1989, a fish kill was discovered in the circulating water discharge bay at the V. C. Summer Nuclear Station (see Figure 1). The numbers and species of fish found are presented below.
Number of Fish identification Size 17 white catfish 7-11 inches 6 channel catfish 11-15 inches 1 bluegill 6 inches I 2 unidentified sunfish < 6 inches 30 threadfin shad 2 inches The fish were bloated and appearea to have been killed during the night of August 21, 1989. The cause of the kill appears to have been a temperature fluctuation in the circulating water discharge bay., A review of temperature data recorded in the discharge bay showed a temperature fluctuation of 10*F on August 21,1989. This temperature fluctuation coincided with a fluctuation in Monticello Reservoir level (see Table 1). This phenomenon is consistent with data gathered during previous kills this summer. Dissolved oxygen (surface 5.2 mg/l, bottom 4.95 mg/l) and pH (surface 6.7) readings in the discharge bay also support the conclusion that the kill was thermalin nature. Although there have been problems with high pH values in wastewater treatraent ponds this summer, this does not appear to be a contributing factor.
