20545 d] M Re: Oconee Nuclear Station Docket Nos.C50-26Q -270, -287,
M; S.k
Dear Mr. Giambusso:
On November 21, 1974, six of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station were inspected. A total of 685 small fingerling fish, weighing 1,150 grams, had collected on the screens.
The fish, averaging 1.7 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 1,150 grams of fish had an insignificant effect on fisheries resotrees in Lake Keowee.
Very truly yours, I
