## Description

On February 22, 2018, the NRC issued a Notice of Violation to Exelon Generation Company (Exelon) for a violation of Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion XVI at Clinton Power Station, associated with a White Significance Determination Process finding. Contrary to the requirements, Exelon failed to assure that a condition adverse to quality was corrected. Specifically, Exelon failed to correct a degraded condition identified during an evaluation performed as a result of a Division 3 Shutdown Service Water pump failure in 2014. This failure resulted in a subsequent failure of the pump to run when tested in June 2017. Additionally, there are associated violations of Technical Specification 3.5.1, "ECCS-Operating," which requires High Pressure Core Spray (HPCS) to be restored to operable within 14 days and Technical Specification 3.7.2, "Division 3 Shutdown Service Water (SX) Subsystem" which requires HPCS to be declared inoperable immediately when SX is inoperable.
