NRC CAL – NOV (White)

On June 6, 2009 a Notice of Violation was issued to Florida Power and Light Energy Duane Arnold, LLC for a violation associated with a White Significance Determination Finding involving a violation of 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Actions." Specifically, the licensee initially identified and corrected a condition adverse to quality regarding overspeed trip alarms on the Train B emergency diesel generator (B EDG), a safety-related component covered under 10 CFR Part 50, Appendix B, in February and March 2008. However, when spurious overspeed trip alarms began recurring in June 2008, the licensee did not perform any additional evaluation to identify the cause for the new condition adverse to quality and did not correct the recurring spurious overspeed trip alarms. This allowed the overspeed switch degradation to continue, resulting in the failure of the B EDG during the monthly surveillance test conducted in November 2008.
