Issued		 Description
EA-22-062
Quad Cities Nuclear Power Station, Unit 2		 NOV
(White)		 11/29/2022 On November 29, 2022, the NRC issued a notice of violation associated with a white significance determination process finding to Constellation Energy Generation, LLC (licensee) at the Quad Cities Nuclear Power Station, Unit 2. The white finding, an issue of low-to-moderate safety significance, involved the failure of one of the four electromatic relief valves (ERVs) associated with the automatic depressurization subsystem to actuate during surveillance testing. The NRC determined that the ERV inoperability resulted from the licensee’s failure to have documented procedures of a type appropriate to the circumstances for rebuilding the 2-0203-3B ERV solenoid actuator, which failed to meet the requirements of Title of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion V.
EA-06-112
Quad Cities 1 & 2		 NOV
(White)		 06/29/2006 On June 29, 2006, a Notice of Violation associated with a White SDP finding was issued for a finding involving the failure to establish measures to ensure that the Unit 1 electromatic relief valves (ERVs) remained suitable for operation prior to implementing an extended power uprate (EPU) in November 2002. This resulted in multiple ERVs becoming inoperable and unavailable due to being subjected to significantly higher vibration levels during Unit 1 operation at EPU power levels.
