NRC CAL – NOV (White)

On September 1, 2015 the NRC issued a Notice of Violation associated with a White Significance Determination Process finding to Entergy Nuclear Operations, Inc. for a violation of 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action". This violation involved the failure to establish measures to promptly identify and correct a significant condition adverse to quality, or take corrective actions to preclude repetition, relating to a component that is essential to performing the Automatic Depressurization System (ADS) safety-related functions. Specifically, the licensee failed to identify that the ADS 'A' safety/relief valve (SRV) did not open upon manual actuation on February 9, 2013. The licensee therefore did not take action to preclude repetition, which resulted in the failure of the ADS 'C' SRV to operate upon manual actuation on January 27, 2015. Additionally, because the licensee was not aware of the 'A' SRV's inoperability from February 9, 2013 until January 27, 2015, a period greater than the allowed Technical Specification (TS) outage time, the required actions of the TS were not followed.
