RESPONSE

TO GENERIC LETTER 88 01 NRC POSITION ON IGSCC IN BWR AUSTENITIC STAINLESS STEEL PIPING" tTAC NOS. 69158 AND 69159)

RE 'US(UEHANNA STEAM ELECTRIC STATIONs UNITS 1 AND 2 We have completed our review of your responses dated August 10 and 18, 1988, and October 2, 1989 to Generic Letter 88-01.

Our review was conducted with the assistance of our contractor, Viking Systems International (VSI).

Our Safety Evaluation and our contractor's Technical Evaluation Report are enclosed.

The staff has reviewed the TER and concurs with the evaluations, conclusions, and recommendations contained in the TER with the exception of VSI's evaluation of your position on crack evaluation.

The staff's exceptions are summarized in the Safety Evaluation (enclosure 1).

The staff has re-evaluated the requirements for frequency of leakage monitoring.

After discussions with several BWR licensees, the staff concluded that monitoring every four hours creates unnecessary hardship to the plant operators.

Therefore, RCS leakage measurements may be taken every eight hours instead of four hours specified in GL 88-01.

Our safety evaluation precludes the necessity for you to submit IGSCC inspection plans for each future outage.

However, if flaws are found that do not meet Paragraph IWB-3500 criteria of Section XI of the ASME Code for continued operation without evaluation, the evaluations and repairs of the flaws should be submitted to the NRC for review prior to start-up.

In GL-88-01 the staff requested the licensees to incorporate the leak detection and piping ISI requirements in the Technical Specifications (TS).

Accordingly, please submit the requisite TS change requests in a timely manner.

Sincerely
