NRC CAL – NOV (White)

On September 16, 2005, a Notice of Violation was issued for a violation associated with a White SDP finding involving the licensee's failure to implement design control measures to verify and check the adequacy of the auxiliary feedwater (AFW) system design to mitigate all postulated accidents. Specifically, the AFW pump discharge pressure trip switches would not have protected the AFW pumps from air ingestion during natural events such as a tornado and seismic events. In addition, the AFW system design would not have protected the pumps from "runout" conditions that may be encountered during the other design and license basis scenarios.
