Title | Failure to Satisfy TS LCO 3.6.1.3 |
Description | An NRC identified NCV of Technical Specification Limiting Condition of Operation (TS LCO) 3.6.1.3 was identified for the licensee's failure to satisfy the TS LCO. Specifically, the licensee failed to satisfy the LCO in two instances because two traversing incore probe (TIP) primary containment isolation valves (PCIVs) were inoperable for a duration that exceeded the Technical Specification (TS) Completion Time before the condition was corrected and discovered. Because the valves were operable upon discovery, no immediate corrective action was necessary. The violation was entered into the licensee's corrective action program as PER 1008300. The performance deficiency was more than minor because it was associated with the SSC & Barrier Performance attribute of the Barrier Integrity cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that the physical design barrier of containment protects the public from radionuclide releases caused by accidents or events. Because PCIVs 3-FCV-94-504 and 3-FCV-94-505 were inoperable and resulted in the failure to satisfy TS LCO 3.6.1.3, reasonable assurance of the integrity of the containment design barrier was adversely affected. The inspectors determined the finding was Green because the TIP lines are a part of a closed system which would not generally contribute to Large Early Release Frequency (LERF). The inspectors determined that the finding had a cross-cutting aspect in the Problem Identification and Resolution area of Identification [P.1], because individuals did not completely, accurately, and in a timely manner identify that the malfunction of the TIP drive mechanisms impacted PCIV operability. |
