20535 Re: Oconee Nuclear Station Docket Nos. 50-269, -270, -287
Dear Mr. Giambusso:
On March 28, 1975, eight of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of approximately 12,000 small fingerling fish, weighing 29.75 kilograms, had collected on the screens. The fish, averaging 2.3 grams per fish, were removed from the screens and categorized, where possible, es 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 29.75 kilograms of fish had an insignificant
~
effect on fisheries resources in Lake Keowee.
Very truly yours,
---?
