ANNUAL-REPORT

• TECHNICAL SPECIFICATION 6.9.1.5 HOPE. CREEK GENERATING STATION DOCKET'NO. .50-354 Th'is'_ annual'Jreport' of challenges to Main Steam Line Safety : / ..

Relief Valves (SRVs)- is being- submitted pursuant 'to - the '

requirements of Technical : Specification 6.9.1.5 for- the year:

11989.

s During 1989, -Hope- Creek experienced the following- unplanned-challenges to SRVs-:

'l.- _On 12/30/89,-- SRVs "H" and "M" lifted automatically _to control reactor _ pressure during

- the course of a' reactor. scram. 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).

- 6 SRVs were within required setpoint tolerances.
