$3 EVENT DESCRIPTION AND s'ROSABLE CONSEQUENCES h ITTTI I During normal operation, LPCI suction valve MO-2-1501-5C failed to close while per-1 iTTT1 I forming DOS 1500-1 LPCI system valve operability test. The valve was hand cranked l

[o I. l l off the back-seat and cycled three times satisfactorily.

Since the valve is open l

l o i s I l during LPCI operation and the LPCI pump operability was notimpaired, safety sig-l lo l6 l l nificance was minimal. This is the first occurrence of this type of failure.
