Subject:

Additional Information Regarding Technical Specification Bases Change for Auxiliary Feedwater Flow (TAC No. 65068)

Gentlemen:

Per the request of Mr. A. W. DeAgazio and Ms. A. Gilbert, NRC Staff, Toledo Edison provides the following clarification regarding the Technical Specification Bases change related to a reduction in Auxiliary Feedwater (AFW) flow.

l The normal loss of feedwater analysis submitted in Serial No. 1360 dated March 23, 1987 was determined to be the most limiting USAR Chapter 15 analysis for a decrease in the AFW flow requirement from 800 gpm to 600 l

gpm.

The feedwater line break accidents were reviewed as part of the review of Chapter 15 accidents and it was determined that these transients were not significantly affected by a decrease in AFW flow.

The conclusions of the safety evaluation supporting the proposed change in Serial No. 1360 to the Technical Specification Bases remain unchanged based on the above. Toledo Edison requests this change'to the Bases be issued expeditiously for implementation.

Very truly yours,

/
