J4 40 42 43 44 47 CAUSE DESCRIPTION AND CORRECTIVE ACTIONS h li101l The circuit breaker failed to close by remote auto or manual initiation, due to a l ii lii I failed open closing coil. The coil was replaced, tested satisfactory, and the I i 7 l service water pump returned to service within T.S. time limits. This closing i i 3 l coil failure is considered spurious (non-recurrent) and requires no further l li l4 l l corrective action.
