Title | Failure to Use Largest Load During EDG Reject Surveillance Test |
Description | The team identified a finding involving a non-cited violation of James A. FitzPatrick Technical Specification (TS) Surveillance Requirement (SR) 3.8.1.8 because Entergy did not adequately perform the largest post-accident load rejection test as required by the SR. Specifically, Entergy\'s surveillance test that implemented this SR rejected a load of about 1000 brake horse power (BHP) and the largest post-accident load calculated by Entergy was 1270 BHP. Entergy entered this issue into their corrective action program to evaluate operability of each emergency diesel generator (EDG) subsystem and to correct the surveillance test for rejection of the largest postaccident load. The team reviewed Entergy\'s operability determination and concluded it appropriately determined the EDG subsystems were operable but non-conforming to SR 3.8.1.8. This finding is more than minor because it is associated with the Procedure Quality Attribute (maintenance and testing) of the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating event to prevent undesirable consequences. The team performed a Phase 1 SDP screening, in accordance with NRC IMC 0609, Attachment 4, \"Phase 1 - Initial Screening and Characterization of Findings,\" and determined the finding was of very low safety significance (Green) because it was a qualification deficiency confirmed not to result in loss of operability. The team did not identify a cross-cutting aspect associated with the finding. |
