Title | Lack of Operator Procedure Use During System Alignment |
Description | A self-revealed finding of very low safety significance and a non-cited violation of Technical Specification 5.4.1 was identified on April 9, 2010, due to the licensees failure to implement Step 5.1.1 of Procedure FP-G-DOC-03, Procedure Use and Adherence. Step 5.1.1 of FP-G-DOC-03 required that personnel perform activities affecting quality using working copies of continuous or reference use procedures. However, operations personnel failed to use a working copy of reference use Procedure C37.13, Containment and Auxiliary Building Cooling System, when performing valve alignments to support the performance of a surveillance test. The failure to use a working copy of C37.13 resulted in the operator performing a valve alignment incorrectly and a loss of one-half of the Unit 2 containment cooling system. Corrective actions for this issue included restoring the containment cooling system, briefing licensee personnel on the event, and reinforcing the use of the human performance tools. The inspectors determined that this finding was more than minor because it was associated with the human performance attribute of the Mitigating System Cornerstone and impacted the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors determined that this finding was of very low safety significance because it did not represent a loss of a system safety function, the fan coil units were inoperable for less than the Technical Specification allowed outage time, and the finding was not potentially risk significant due to external events. The inspectors determined that this finding was cross-cutting in the Human Performance, Work Practices area because licensee personnel did not ensure human error prevention techniques were used such that work activities were performed safely (H.4(a)).
