Gentlemen:

Subject:

Oyster Creek Nuclear Generating Station Docket No. 50-219 Generic Letter 89-13 By letter dated January 30, 1990, GPUN responded to Generic Letter 89-13,-

" Service Water System Problems Affecting Safety-Related Equipment". In our letter we described a containment spray heat exchanger performance monitoring program to be in effect prior to startup from the cycle 13 refueling outage.

In a subsequent lette' dated June 21, 1991, GPUN explained that additional instrumentation had been installed to measure heat exchanger performance, however the test procedure needed to initiate the program wculd not be completed until October 1,1991.

Please be advised that additional time will be needed to complete the procedure. As stated in our response to Generic letter 89-13, " Testing of the heat exchanger will only be possible when there is sufficient temperature differential between the intake canal and the torus water, such as in the fall months." lhere is still insufficient temperature differential at this time, therefore development of the procedure can be deferred. Accordingly, this procedure will be in place by November 15, 1991 at which time implementation of the program will be completed.

If there are any questions regarding this matter, please call Mr. Michael Heller, Licensing Engineer, at (609) 971-4680.
