A self-revealing NCV of 10 CFR 50.65(a)(1) … A self-revealing NCV of 10 CFR 50.65(a)(1) was identified for failure to perform monitoring of the service water intake structure (SWIS) seismic rings resulting in the inability of 2A, 2B, 2C, and 2E service water pump (SWP) seismic rings to perform their function. The support function of the seismic ring of these pumps failed due to degradation of the fasteners. The licensee entered the issue into the CAP as CR 2009109700. The licensee completed corrective actions to restore functionality of the 2A, 2B, 2C, and 2E SWP seismic rings. The failure to perform monitoring of the SWIS seismic rings resulting in the inability of the 2A, 2B, 2C, and 2E SWP seismic rings to perform their function is a performance deficiency. This finding was more than minor because it adversely affected the equipment reliability attribute of the MS cornerstone objective to ensure the availability, reliability and capability of systems responding to initiating events to prevent undesirable consequences (i.e., core damage). This finding was assessed using the Phase 1 screening worksheet of the SDP and determined to be of very low safety significance (Green) because the safety function of the service water pump was determined to not be degraded. The finding is associated with a cross-cutting aspect in the CAP component for the Problem Identification and Resolution (PI&R) area in that the licensee did not complete actions identified in the corrective action program which included inspections of wet pit fasteners.(P.1(d))uded inspections of wet pit fasteners.(P.1(d)) +
