Finding

Title

Failure to Analyze Reactor Recirculation System Motor Operated Valves for the Post-fire Cold Shutdown Function

Description

The team identified a finding of very low safety significance involving a non-cited violation of Pilgrim Operating License Condition 3.F for failure to implement and maintain all aspects of the approved Fire Protection Program. Specifically, Entergy's post fire safe shutdown analysis did not adequately evaluate system requirements necessary to achieve cold shutdown conditions when the A Reactor Recirculation System motor operated valves are damaged by fire. As a result, Entergy may not have been able to establish cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, as required by their safe shutdown analysis and regulatory requirements for this scenario. Entergy entered this issue into their corrective action program as condition reports CR-PNP-2015-09136 and CR-PNP-2015-09400, and implemented fire watches in the affected fire areas as an interim compensatory measure. The finding was more than minor because it was similar to example 3.k of the NRC Inspection Manual Chapter (IMC) 0612, Appendix E, "Examples of Minor Issues," and was associated with the Protection Against External Factors (e.g., fire) attribute of the Mitigating Systems Cornerstone and adversely affected the objective to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The team performed a Phase 1 Significance Determination Process (SDP) screening, in accordance with IMC 0609, Appendix F, "Fire Protection SDP." This finding screened to very low safety significance (Green) because it did not affect the ability to reach and maintain a hot shutdown condition (i.e., it only affected the ability to reach or maintain cold shutdown conditions). This finding had a cross-cutting aspect in the area of Problem Identification & Resolution, Evaluation, because, in 2013, Entergy incorrectly assumed that the B RRS MOVs would be available during any fire that could damage the A MOV cables without thoroughly evaluating whether the routing for the B MOV cables ensured they would remain undamaged and available.
