Preliminary Report, June 1989 Fish Kill A fish kill was discovered in the Circulating Water Discharge bay (see Figure 1) 1 at V. C. Summer Nuclear Station in the morning of June 26,1989. A total of twenty-j four fish were found and examined. The fish were all catfish,5 to 8 inches in total j

length. Most were white catfish, a few were identified as channel catfish. Most fish were badly decomposed and had apparently been dead for over 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Tempera-ture data and the lack of any indication of unusual discharges infer that the fish kill was probably the result of increased temperatures at the bottom of the discharge bay. It was suspected that the fish kill occurred late on 6/24/89. There were no fluctuations in power level it V. C. Summer Nuclear Station during the suspected time of the kill. After notification of regulatory agencies, eight more fish were noted in the discharge bay (approximately 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />).

The discharge area has been repeatedly inspected and there is indicatic a that this is a series of fish kills, probably occurring late at night. On 6/27/89 eighteen dead fish were discovered (all catfish) and on 6/28/89 seventy-four dead fish were discovered. When it was realized that fish were continuing to be killed, regulatory agencies were notified. Since fish kills recurred after the initial notification, this is only a preliminary repcsrt A complete report will be submitted after all pertinent data has been evaluated.
