| Title | |
| Description | The inspectors identified a Green NCV of License Condition 3.F of the Pilgri
facitity Operating License (DPR-35) for the failure to evaluate transient combustible fir loading in the Standby Liquid Control (SLC) room. Specifically, Entergy did not evaluat the acceptability of transient combustibles that had been moved into the SLC room whic were in excess of the allowed combustible loading discussed in the Fire Hazards Analysis Entergy immediately walked down the area, established compensatory measures, an completed a transient combustibles evaluation. Entergy has since removed the transien combustibles from the area The inspectors determined that the failure to evaluate the transient combustibles was mor than minor based on a similar example described in Inspection Manual Chapter 0612 \\\"Power Reactor Inspection Reports,\\\" Appendix E, \\\"Examples of Minor lssues,\\\" Section 4k Specifically, the fire loading exceeded the Fire Hazard Analysis assumption and was no evaluated for acceptability. The finding is also associated with the Protection Agains External Events attribute of the Mitigating Systems cornerstone and could have adversel affected the cornerstones objective to ensure the availability of systems that respond t events to prevent undesirable consequences (i.e,, core damage). Specifically, a fire in th SLC room could affect the availability of the SLC system to respond to an event. IMC 0609 \\\"significance Determination Process,\\\" Appendix F, \\\"Fire Protection Significanc Det,ermination Process,\\\" was used to evaluate the significance of the finding. The safet significance of the finding was determined to be very low because the degradation facto was low; that is, the transient combustible evaluation process subsequently identified nearl the same level of fire protection effectiveness and reliability for the SLC room as it woul have if the degradation had not been present This finding had a cross-cutting aspect in the Human Performance cross-cutting area Work Control component; in that, Entergy did not coordinate work activities to ensure th interdepartmental coordination necessary to assure plant and human performance Specifically, the refueling organization did not notify fire protection engineering to ensure a evaluation of the\\\'transient combustible loading was completed for the SLC room (Section 1R05) |
