NRC CAL – NOV (White)

On January 3, 2012, the NRC issued a Notice of Violation to Entergy Nuclear Operations, Inc. for a violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," associated with a White Significance Determination Process finding involving Entergy's failure to prescribe maintenance on the safety-related turbine driven auxiliary feedwater pump, an activity affecting quality, by documented instructions of a type appropriate to the circumstances, as well as a failure to accomplish the maintenance in accordance with their procedure. Specifically, on October 17, 2010, procedure FWS-M-6, "Auxiliary Feedwater Turbine Maintenance," failed to prescribe inspections of wear conditions on the knife edge and latch plate, or to replace the trip spring, although these inspections and replacements had been identified as necessary by the turbine vendor. Palisades' personnel also failed to perform a step in the surveillance procedure which required lubricating a pin and instead greased the knife edge of the mechanical overspeed/manual trip mechanism. These deficiencies resulted in the turbine driven auxiliary feedwater pump being inoperable from October 29, 2010 to May 11, 2011.
