Finding

Title

Licensee-Identified Violation

Description

10 CFR Part 50, Appendix B, Criterion III, Design Control, required, in part, that design control measures shall provide for verifying or checking the adequacy of the design. Contrary to the above, as of November 1, 2011, the licensees design control measures failed to verify the adequacy of the auxiliary feedwater (AF) design. Specifically, licensee personnel identified that for a design basis event with the switchyard and condensate storage tank unavailable, multiple diesel-driven AF pump starts could occur. At the time the issue was identified, the licensee had not evaluated the potential adverse consequences (i.e., draining the battery used for starting the machine, exceeding the starter motor starting duty limitations, and ensuring AF supply to the steam generators within the timeframe assumed in the accident analysis.) The licensee performed an operability evaluation and concluded that the pump was operable. This finding was determined to be Green based upon the conclusions reached in the operability evaluation and inspectors review of those conclusions. This issue was entered into the licensees CAP as IR 1285319. Corrective actions included an assignment to review eliminating or minimizing multiple AF starts.
