SRV "P" should<haveLopened,_.but did not due toia failed-pressure J switch.

(Ref: LER 89-025-00)._

Pleace note that SRV::"H" and SRV "P". are the lo-lo set SRVs at Hope s

Creek, and are designed to arm and initially lift at 1047 PSIG.

Additionally, during the 1989 refueling outage, all SRVs twere=

replaced and' lift tested following replacement.- 'All replaced SRVs1 tested satisfactorily.

As-found bench testing of the SRVs which were removed determined the following:

8 SRVs tested 'at a setpoint greater than the acceptance

. criteria of<

1% (SRVs A,C,D,E,K,L,M, and P) as specified in Technical. Specification 3.4.2.1.

These SRVs will be rebuilt-and. tested prior to next scheduled installation (1991 refueling outage).
