| Title | Lack of Basis for Diesel Fire Pump Temperature DE-RATING |
| Description | A finding of very low safety significance and an associated NCV of the Fermi 2 Facility Operating License condition 2.C(9), for the fire protection program, was identified by the inspectors for the failure to provide a design basis for the general service water pump house (GSWPH) ambient temperature of 104F used to evaluate the capacity of the diesel fire pump. The licensee entered the issue into their corrective action program and completed a preliminary analysis that showed the 104F as a bounding value. The finding was more than minor based on review of IMC 0612, Power Reactor Inspection Reports, Appendix E, Examples of Minor Issues, Example 3k. Specifically, the failure to provide a design basis for the assumed general service water pump house ambient temperature resulted in a reasonable doubt with regards to the functionality of the diesel fire pump because minimal margin for operability existed. The finding affected the mitigating systems cornerstone attribute of protection against external factor (fire) and it impacted the objective of the mitigating systems cornerstone. The inspectors concluded that the finding was of very low safety significance because the finding represented a low degradation since the functionality of the diesel fire pump was not affected.
