NRC CAL – NOV (White)

On April 7, 2006, a Notice of Violation was issued for a violation associated with a White SDP finding involving a challenge to reactor coolant system (RCS) integrity by multiple pressurizer power-operated relief valve (PORV) actuations and a challenge to RCS inventory control by loss of RCS coolant via the open PORV. This occurred on February 22, 2005, during transition to solid plant operations. The violation cited the licensee's failure to slowly raise charging flow to fill the pressure at less than 30 gallons per minute as required by Technical Specification 5.7.1.1 and Procedure GO-6, Unit Stutdown from Hot Standby to Cold Shutdown.
