NRC CAL – NOV (White)

On November 12, 2009, the NRC issued a Notice of Violation to Constellation Energy for a violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," at the R.E. Ginna Nuclear Power Plant. The violation, which is associated with a White Significance Determination Process finding, involved the failure to identify the cause of a significant condition adverse to quality. Specifically, after identifying corrosion on the turbine-driven auxiliary feedwater pump governor control valve stem on April 11, 2005, the licensee did not take adequate measures to identify the cause or prevent recurrence. This led to additional corrosion and binding of the governor control valve, and resulted in failure of the turbine-driven auxiliary feedwater pump on July 2, 2009.
