On July 30, 2020, the NRC issued a Notice of Violation to Virginia Electric and Power Company (Licensee), associated with a White Significance Determination Process finding. The white finding, an issue of low to moderate safety significance, involved the failure of the Surry Power Station Unit 2 turbine-driven auxiliary feedwater (TDAFW) pump discharge check valve during surveillance testing. Specifically, from November 23, 2005, to November 20, 2019, the licensee did not analyze common failure or maintenance patterns to determine their significance and to identify potential failure mechanisms of the valve when establishing its check valve condition monitoring program in accordance with the 2004 ASME Code for Operation and Maintenance of Nuclear Power Plants, Mandatory Appendix II, as required by 10 CFR Part 50.55a(f)(4). As a result, all three Unit 2 auxiliary feedwater pumps were declared inoperable, and the safety function was considered lost until the TDAFW line was isolated.
