20555 Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287
Dear Mr. Giambusso:
On March 14, 1975, six of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 30,000 small fingerling fish, weighing 66 kilograms, had collected on the screens. The fish, averaging 2.2 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 66 kilograms of fish had an insignificant
,effect on fisheries resources in Lake Keowee.
Very truly your ;
