Re: Oconee Nucles-9tation 1-
-p -270, -287 Docket No
Dear Mr. Giambusso:
On December 19, 1974, ten of the 24 condenser cooling water (CCW) intake screens at the Oconee Nuclear Station w re inspected.
A total of 11,760 small fingerling fish, weighing 19.4 kilograms, had collected on the screens.
The fish, averaging 1.6 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 j
the mortality of these 19.4 kilograms of fish had an insignificant effect on fisheries resources in Lake Keowee.
Very truly yours,
/s': n',
