20555 Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287
Dear Mr. Giambusso:
On January 30, 1975, six of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 1,404 small fingerling fish, weighing 3.4 kilograms, had collected on the screens. The fish, averaging 2.4 grams per fish, were removed from the screens and categorized, where possible, as to screen location, type, size, degree of decomposition, and weight. This information is tabulated in Enclosure 1.
It is concluded that the mortality of these 3.4 kilograms of fish had an insignificant effect on fisheries resources in ke Keowee.
V truly yours,
