| Title | Inadequate Procedures Result in the Failure to Evaluate Operability of the B RBCCW/SSW Heat Exchanger |
| Description | The inspectors identified a NCV of very low safety significance (Green) of 10 CFR Part50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because Entergy procedures directed operators to take corrective actions for degra.ded conditions prior to assessing operability of the affected system. Specifically, operators conducted corrective actions (backwashing) of the B RBCCWISSW heat exchanger (HX) prior to assessing operability when the HX failed to meet the procedural differential pressure (dP) acceptance criteria. Entergy entered this issue into their CAP (CR-PNP-2009-03596) and performed a past operability evaluation which showed that the HX would have been able to meet its intended function during accident conditions. The finding is more than minor because if left uncorrected, it has the potential to lead to a more significant safety concern. The finding was determined to be of very low safety significance (Green) because the finding did not involve a design or qualification deficiency resulting in loss of operability or functionality, did not result in a loss of system safety function, and did not screen as potentially risk significant due to external initiating events. The inspectors determined that this finding had a cross-cutting aspect in the Resources component of the Human Performance cross-cutting area because Entergy did not provide procedures adequate to ensure nuclear safety.
