REACTOR SAFETY (Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity)

1R04 Equipment Alignment

a.

Inspection Scope

On April 6, 2000, the licensee performed planned maintenance on the 31 residual heat removal pump breaker (powered from the 31 emergency diesel generator (EDG)), the 312 auxiliary feedwater pump room fan, and performed surveillance test PT-M62 “480V Under Voltage/Degraded Grid Protection System Functional.” During these activities, the inspector performed a partial system walkdown of the starting air and fuel oil systems of the 32 EDG, and of the starting air system on the 33 EDG.

During May 17 - 24, 2000, the inspector performed a partial walkdown of the containment isolation valve (CIV) system after three solenoid-operated valves (SOV- 512, -513, and -514) in the CIV system were de-energized for preventive maintenance. The inspection focused on the alignment of the 15 high risk significant CIVs, and all other system valves that receive a “Phase A” containment isolation signal (closure of all nonessential process lines following a safety injection actuation) and a “Phase B” isolation signal (i.e., closure of all essential process lines following an actuation of containment spray).
