l This letter provides an updated status of Hope Creek's implementation of commitments i to Generic Letter 89-13, " Service Water System Problems Affecting Safety-Related j Equipment," which was issued by the NRC on July 18,1989. In that Generic Letter, the i NRC required licensees to submit information concerning: 1) how their service water I system satisfies regulatory requirements; and 2) how the safety functions of their service water systems are being met. On August 1,1997, via letter LR-N97411, Public Service Electric & Gas Company (PSE&G) provided an update on the status of Hope Creek's response to Generic Letter 89-13. In PSE&G's letter, Hope Creek had committed, in part, to: 1) inspect and clean the Safety Auxiliaries Cooling System (SACS) heat exchangers for two refueling outages (RFO7 and RFO8); and 2) collect baseline tube-side pressure drop readings of the heat exchangers and periodically monitor the Station Service Water System (SSWS) pressure drop across SACS heat exchangers to detect the onset of macrofouling.

Since the iss' ance of PSE&G's August 1,1997, letter, Hope Creek has performed the aforementioned inspection and cleaning of the SACS heat exchangers during RFO7 and RF08. These inspections identified relatively minor quantities of grass and silt, with no significant microfouling present. However, during this period, the installed i instrumentation could not effectively measure tb3 associated small changes in the pressure drop parameters with little macrofouling present. Accordingly, Hope Creek's commitment to Generic Letter 89-13, to obtain heat exchanger baseline date, could not be appropriately satisfied. , ,

F MAY10 Eg Document Control Desk LR-N99189 Therefore, PSE&G is revising Hope Creek's commitment to Generic Letter 89-13 to include the following:

1. During the next refueling outage, RFO9, Hope Creek will open, inspect and clean ,

the SACS heat exchangers in a manner consistent with the previous two {

outages. An appropriate frequency for SACS heat exchanger inspections will '

then be determined based upon the data collected during RFO7, RFO8 and RFO9. l

2. Using portable test equipment, baseline pressure drop readings will be taken by June 1,1999 for all four SACS heat exchangers. Periodic pressure drop readings will then be taken as necessary (initially quarterly) in order to monitor the heat exchanger such that the onset of macrofouling can be detected. Test equipment options for future measurements will be evaluated.

Should you have any questions regarding this request, please contact Mr. James Priest at 609-339-5434.
