Finding

Title

Inop RCIC Primary Containment Isolation Valves

Description

A finding of very low safety significance and an NCV of TS 5.4.1.a were self-revealed by the failure of the Unit 1 reactor core isolation cooling (RCIC) steam exhaust check valve that resulted in a trip of the RCIC system and created a condition where both containment isolation valves in the RCIC steam exhaust line would not have performed their primary containment isolation function. The finding involved the licensees failure to effectively monitor the condition of the check valve. Periodic non-destructive examination of the check valve had been discontinued in 1996 in favor of a reliance on local leak rate testing, which was insufficient to detect degradation prior to this failure. The licensee performed a normal shutdown of Unit 1 when this condition was identified, and the inboard and outboard primary containment isolation valves were repaired prior to restart. Corrective actions included a revision of the preventive maintenance for the valve to require periodic replacement of the valve internals. This finding is more than minor because it challenged the Barrier Integrity Cornerstone attribute for Containment Isolation functionality. The inspectors performed a Phase 1 SDP screening and the IMC 0609, Attachment 4, Table 4a, Containment Barrier questions were all answered, No. Therefore, the issue screened as Green or very low safety significance. The inspectors determined that this finding did not have a cross-cutting aspect because the licensees decision to discontinue periodic inspections of the RCIC steam exhaust check valves in 1996 was not subject to the program review that the licensee currently employs; therefore, this performance deficiency is not indicative of current licensee performance
