NRC CAL – NOV (White)

On September 3, 2021, the NRC issued a revised Notice of Violation to Exelon Generation Company, LLC (Licensee), associated with a White Significance Determination Process finding. The white finding, an issue of low to moderate safety significance, involved the failure of James A. FitzPatrick Nuclear Power Plant (FitzPatrick) personnel to accomplish activities affecting quality in accordance with procedures for controlling nonconforming components contrary to Title 10 of the Code of Federal Regulations (CFR) Part 50, Appendix B, Criterion V, “Instructions, Procedures, and Drawings,” 10 CFR Part 50, Appendix B, Criterion XV, “Nonconforming Materials, Parts, or Components,” and FitzPatrick Technical Specifications (TSs). Specifically, from December 16, 2017, to April 10, 2020, Exelon failed to initiate an action at FitzPatrick to track resolution of a nonconforming Pressure Control Valve (PCV) before its transfer occurred, did not add it to the receiving site’s hold tag log, and did not attach a hold tag upon receipt. As a result, on December 16, 2017, Exelon did not identify that the PCV’s diaphragm required replacement and installed the nonconforming PCV in the High Pressure Coolant Injection (HPCI) system. Consequently, the HPCI system was rendered inoperable prior to April 10, 2020, for a period longer than its TS allowed outage time, and the unit was not shut down and placed in Mode 3 within 12 hours in accordance with requirements.
