Title

Incompatible procedures result in 6400 gallon drain of spent fuel pool

Description

A self-revealing noncited violation of 10 CFR Part 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified after the licensee followed two incompatible procedures simultaneously resulting in the inadvertent partial draining of the spent fuel pool. Consequently, approximately 6400 gallons of water was pumped from the spent fuel pool to the refueling water storage tank. Wolf Creek subsequently initiated Condition Report 2008-002035. Failure to prevent spent fuel pool draining due to simultaneous performance of incompatible Procedures SYS EC-200 and SYS EC-320 is considered a performance deficiency. This finding is more than minor because it impacted the barrier integrity cornerstone attribute of configuration control and affected the cornerstone objective to maintain functionality of the spent fuel pool system. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, this finding was determined be of very low safety significance because the finding only affected the barrier function of the spent fuel pool. The inspectors determined that the finding has a human performance crosscutting aspect in the area associated with work control, because Wolf Creek did not coordinate work activities among separate groups, assess the impact of these concurrent evolutions, or track the alignment of the fuel pool clean-up system H.3.b] (Section 1R04).
