20555 Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287
Dear Mr. Boyd:
On August 14, 1975, six of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 350 small fingerling fish, weighing 795 grams, 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 795 grams of fish had an insignificant effect on fisheries resources in Lake Keowee.
Ve truly yours, e
f _ a.
