| Title | Emergency Diesel Generator Room Cooling Fan Testing Deficiences |
| Description | A finding of very low safety significance and an associated NCV of10 CFR, Part 50, Appendix B, Criterion III, Design Control, was identified by the inspectors for the licensees failure to verify the ventilation flow rate for the emergency diesel generator (EDG) rooms and for using an incorrect EDG heat load in the design basis calculation of record. As part of corrective actions, the licensee remeasured flow rates and duct dimensions and recalculated post-accident temperature values. This finding was more than minor because a revision to the design calculation was necessary to demonstrate EDG cubicle temperatures would remain under the design basis 120 degrees Fahrenheit (oF) equipment qualification limit under any accident conditions. The finding was of very low safety significance (Green) based on a Phase 1screening in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, dated January 10, 2008, because the revised calculation showed that the diesel generators had remained operable in all circumstances. There was no cross-cutting aspect associated with this finding. (1R21 |
