Public Service Electric and Gas Company Steven E. Miltenberger Public Service Electric and Gas Company P.O. Box 236, Hancocks Bridge, NJ 08038 609-339-4199 Vice President and Chief Nuclear Officer August 28, 1989 NLR-N89097 United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Gentlemen:
REQUEST FOR ADDITIONAL INFORMATION GENERIC LETTER 83-37 SALEM GENERATING STATION UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 This letter is being provided based on a request by Mr. J. Stone, NRC Licensing Project Manager, to clarify PSE&G's position on Generic Letter (G.L.) 83-37 with respect to staggered testing of the Auxiliary Feedwater (AFW) pumps.
Currently, the Salem Technical Specifications require that the AFW pumps be tested once per 31 days, but not on a staggered test basis as suggested by G.L. 83-37.
It is PSE&G's position that the AFW pumps need not be tested on a staggered basis for the following reasons:
staggered testing of the Auxiliary Feedwater Pump is not consistent with the requirements of the currently approved Westinghouse standard Technical Specifications.
Review of several plants of similar vintage to the Salem plants shows no consistent application of staggered testing, even when the surveillance interval is quarterly vs. 31 days as required for Salem.
A review of the Salem PRA model shows that changing from the current test method to staggered testing would not result in any significant increase in overall plant safety.

08-28-89 Testing on a staggered basis increases the work load on station personnel from both an administrative and technical basis without any clear benefit to safety.
PSE&G currently does not routinely use staggered testing unless specifically required.
Tracking of staggered testing therefore places additional burden on plant planning and scheduling personnel.
Additionally, plant operations and maintenance personnel must physically set up and perform the AFW pump test three times a month for staggered testing vs. the once/month currently required.
This increases the number of times per month the operations staff must be aware of AFW pumps being out of service for testing and will add to the day.to day operational burden.
In summary it is PSE&G's position that the implementation of staggered testing is not justified and that the surveillance requirements for the Auxiliary Feedwater Pumps adequately ensures the reliability of the pumps as currently written.
Should you have any questions, please feel free to contact us.
Sincerely, C
