| description = The team identified a non-cited violation of License Condition 2.C.5.a for the failure of the licensee to identify and correct a condition adverse to fire protection. Specifically, the licensee failed to identify an adverse trend in the diesel driven fire water pump oil samples and take appropriate corrective actions. The licensees corrective actions included installing a new diesel driven fire water pump, revising the oil sample procedure and evaluating further corrective actions. This issue was entered into the licensees corrective action program as Condition Report 43710. This performance deficiency was more than minor because it affected the Mitigating Systems Cornerstone attribute of protection against external factors (fire) and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Corrective actions to address the adverse condition were not taken, which led to the catastrophic failure of the right-angle drive for the diesel driven fire water pump. The team performed the significance determination using NRC Inspection Manual Chapter 0609, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, dated January 10, 2008, because it affected the Mitigating Systems Cornerstone while the plant was at power, and concluded the finding needed additional screening under Appendix F, Fire Protection Significance Determination Process, dated February 28, 2005. The team determined that the condition represented a low degradation of the fire protection program element of fixed fire protection systems due to a loss of the diesel driven fire water pump, and using Figure F.1 the finding was determined to be of very low safety significance based on Task 1.3.1. In addition, this finding had a problem identification and resolution cross-cutting aspect associated with the corrective action program component in that the licensee failed to thoroughly evaluate problems such that resolutions address causes and extent of condition | | description = The team identified a non-cited violation of License Condition 2.C.5.a for the failure of the licensee to identify and correct a condition adverse to fire protection.
