Docket No. 50-244 Dr. Robert C. Mecredy, General Manager Nuclear Production Rochester Gas

& Electric Corporation 89 East Avenue Rochester, New York 14649 July 10,

SUBJECT:

WESTINGHOUSE REASSESSMENT OF BULLETIN 88-02 FOR R.E.

GINNA NUCLEAR POWER PLANT (TAC NO. 67308)

A number of PWR licensees contracted Westinghouse to perform the analyses requested by NRC Bulletin 88-02, "Rapidly Propagating Fatigue Cracks in Steam Generator Tubes."

During its review of these

analyses, the staff noted a

pattern of deficiencies affecting a number of these analyses and requested Westinghouse to review its analyses to identify and address these deficiencies.

In response, Westinghouse informed the NRC staff of its plans to reassess and update these analyses (Enclosure).

You are requested to submit the Westinghouse reassessment to the NRC when you receive it so that the staff can finally resolve this issue.

Your plant is among six of the nine plants being reassessed by Westinghouse which the staff has previously issued safety evaluations concluding that Bulletin 88-02 concerns have been satisfactorily resolved.

Accordingly, your plant is no longer subject to item C.1 of the bulletin which sought an "enhanced primary-to-secondary leak rate monitoring program" for the interim period pending staff review and resolution of the concerns raised in the bulletin.

Now that adequacy of your resolution of the bulletin concerns has been called into question, we request that you recommit to item C.l of the bulletin pending completion of the Westinghouse reassessment and staff review of the reassessment.

Please respond within thirty days informing us of your commitment to an enhanced primary-to-secondary leak rate monitoring program.

Sincerely,

Enclosure:
