June 29, 1979 letter from Cordell Reed to D. F. Ross, Jr.
Dear Dr. Denton:
On June 4, 1979 the NRC Staff requested Westinghouse to provide additional information on the response of the currently operating Westinghous
- designed plants to postulated snall break LOCAs.
Reference (a) requested Cc,nmonwealth Edison Company, as a participant of the Westinghouse Owners Group, to document the applicability of the requested analyses to the Zion Units.
Per Reference (b), the Westinghouse Operating Plants Owners' Group submitted a report responding to the NRC Staff's request.
Commonwnalth Edison has reviewed that report anc has deter-nined that the small break LOCA analyses are applicable to the Zion units.
Therefore, Commonwealth Edisen requests that a copy be placed on the Zion Station Docket, Nos. 50-295 and 50-304.
However, as indicated in Reference (b), Section 6 of the Westinghouse report includes guidelines for tripping reactor coolant pumps and terminating safety injection.
Cor,imonwealth Edison, as wcll as the rest of the Owners' Group utilities, will await NRC Staff approval of these guidelines prior to implementation of them in plant procedures.
