Title | Inadequate Heat Exchanger Inspection Procedure |
Description | The inspectors identified a finding having very low safety significance and a Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to establish inspection procedures that were appropriate for the circumstances for the component cooling water heat exchangers. Specifically, the inspection procedure did not include instructions to verify the as-found essential service water flow rate through the heat exchangers met the minimum required value, which was a prerequisite for the licensees inspection methodology. This finding was entered into the licensees Corrective Action Program with a proposed action to revise the affected procedure. The performance deficiency was determined to be more than minor because, if left uncorrected, it has the potential to lead to a more significant safety concern. The finding screened as of very low safety significance (Green) because it did not result in the loss of operability or functionality. Specifically, the licensee reviewed recent heat exchanger inspection results and reasonably determined the as-found macro fouling conditions did not impacted operability. The inspectors did not identify a cross-cutting aspect associated with this finding because it was confirmed not to be reflective of current performance due to the age of the performance deficiency. |
