SUBJECT:

CHANGE TO COMMITMENTS ASSOCIATED WITH GENERIC LETTER (GL) 89-13,

" SERVICE WATER SYSTEM PROBLEMS AFFECTING SAFETY-RELATED EQUIPMENT,"

JULY 18, 1989, FOR HOPE CREEK GENERATING STATION (TAC NO. M99369)

Dear Mr. Eliason:

On August 1, 1997, Public Service Electric and Gas Company (PSE&G) submitted a letter that changed previous commitments to certain remedial actions suggested by GL 89-13, for Hope Creek Generating Station. Specifically, in a letter dated January 26, 1990, PSE&C had committed to (1) perform periodic Safety Auxiliary Cooling System (SACS) heat exchanger performanco testirg, and (2) perform a single active failure review of the Station Service Water System (SSWS) by March 1991. The August 1, 1997, letter provided alternative commitments.

During an August.25, 1997, telephone conference, the Nuclear Regulatory Commission (NRC) staff and PSE&G discussed proposed changes to the Generic Letter (GL) 89-13 commitments as stated in PSE&G's letter dated August 1, 1997. GL 89-13 recommends that licensees conduct a test program to verify the heat transfer capability of all safety-related heat exchangers cooled by service water.

The program should consist of an initial test program and a periodic retest program. A program acceptable to NRC is the Heat Transfer Method. An alternative action that would be acceptable to the NRC is frequent regular maintenance of a heat exchanger in lieu of testing for degraded i

performance of the heat exchanger. The initial frequency for the maintenance should be at least once each fuel cycle for the first three cycles. Then,

//

i PSE&G should determine the best frequency for testing to provide assurance that the equipment will perform its intended safety functions.

/[

I Based on the August 25, 1997, discussions, it it the NRC staff's understanding that PSE&G has committed to perform the alternative periodic maintenance inspection method on the four SACS heat exchangers in lieu of the Heat Transfer Method. The maintenance will include inspecting, cleaning, and recording a baseline tube-side pressure drop on the SACS heat exchangers during the next two refueling outages (RF07 and RF08).

Between refueling outages, PSE&G plans to monitor the SSWS pressure drop across the SACS heat exchangers to detect the onset of macrofouling. Based on the re:.ults of these nme y e m m caev 9710010211 970919 PDR ADOCK 050003S4 P

L. Eliason inspections, PSE&G plans to establish an appropriate frequency for future SACS heat exchanger inspections. Also, PSE&G plans to take credit for previous SACS heat exchanger ins)ections and eddy current testing that have been performed every 36 montis since 1988, and a B1 heat exchanger inspection in April 1994, in order to satisfy the GL 89-13 initial frequency recommendation.

The NRC staff finds that this change to the GL 89-13 comitment, associated with inspection of the SACS heat exchangers, is acceptavie.

With regard to the second commitment, to perform a single active failure analysis of the SSWS by March 1991, the August 1,1997, letter informs the NRC staff that this analysis was not completed until July 31, 1997. The NRC staff acknowledges the receipt of this notification.

Sincerely,
