It is believed!

li j i j l that these valves isolated earlier in the day when a Group 6 isolation PT was per-I

[ ; T-I l formed. This PT was revised to notif y the operator that these RIP valves must be I

l reset and reopened upon completing the PT.

These RlP valves were recently modified l

f LER CONTINUATION -- RO# 1-80-20 Facility: BSEP Unit #1 Event Date February 6, 1980 The engineering procedure for plant modifications has recently been revised to require that all procedure changes required as a result of the modification be identified and revised before the plant modification is made operational. All other PT's that give a Group 6 isolation will be reviewed and revised as re-quired to ensure that total operability is achieved following the PT.
