| ENS 54923 | 29 September 2020 21:19:00 | On July 22, 2020, at 1030 CDT, it was discovered that the as-found Unit 2 Oscillation Power Range Monitor (OPRM) Maximum Confirmation Count Setpoint did not match the values in the Quad Cities Unit 2 (Core Operating Limits Report) (COLR) per TS SR 3.3.1.3.3. All Unit 2 OPRMs were declared inoperable. Due to this inoperability, the OPRM system was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported per 10 CFR 50.72(b)(3)(v)(D). There were no other Technical Specification or safety systems inoperable at the time of this event. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. Quad Cities Unit 2 returned their OPRMs to operable on July 23, 2020, at 1210 CDT, following a setpoint adjustment. In addition, during a more recent meeting between station personnel and the NRC resident inspectors, feedback was provided that brought to the station management's attention that they needed to make the required 50.72 notification as a result to this past inoperability. |
