Title | |
Description | The team identified a Green NCV of Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix B, Criterion III, Design Control, because Entergy did not ensure that FitzPatricks emergency diesel generator (EDG) lubrication oil (LO) supply storage facility was designed to withstand the effects of natural phenomena. Specifically, additional LO, maintained and inventoried monthly to ensure an adequate LO supply to meet the EDGs seven day mission time, was stored in a non-Class I structure that was not designed to withstand the effects of natural phenomena induced plant events that the EDGs were designed to mitigate. Entergy entered the issue into the corrective action program (CAP) as condition report (CR) 2016-1471 and promptly relocated the LO reserve inventory from warehouse No. 2 to the EDG building, which is constructed to Class I seismic and tornado protection design criteria. The finding was more than minor because it was associated with the protection against external factors attribute of the Mitigating Systems cornerstone and adversely affected the cornerstones objective of ensuring reliability and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The team evaluated the significance of this finding using IMC 0609, Appendix A, The Significance Determination Process for Findings at Power, Exhibit 2 Mitigating Systems Screening Questions. The team determined the finding screened as very low safety significance (Green) because the finding was a design deficiency which did not result in an actual loss of functionality of the EDGs. This finding did not have a cross-cutting aspect because the underlying cause occurred in 1988 during warehouse No. 2 construction and was not indicative of current Entergy performance. |
