List of Findings and Violations

Failure to Establish Required Compensatory Measures When Equipment Important to Emergency Response was Non-Functional Cornerstone Significance Cross-Cutting Report Aspect Section Emergency Green [H.2] - Field 71111.15 Preparedness NCV 05000498/2023004-01 Presence Open/Closed The inspectors identified a Green, non-cited violation of 10 CFR 50.54(q)(2) which requires that operating nuclear power plant licensees follow and maintain the effectiveness of an emergency plan that meets the requirements in Appendix E of 10 CFR 50, and the planning standards of 10 CFR 50.47(b), including 10 CFR Part 50.47(b)(4), relative to maintaining an emergency classification/action level scheme. Specifically, from July 19, 2023, to July 24, 2023, the licensees response to the loss of the control room area radiation monitor, RT-8066, failed to restore capability to classify emergency action level (EALs) RA3, Radiation Levels that impede access to equipment necessary for normal plant operation, cooldown or shutdown, which would rely on monitoring the control room area radiation monitor consistent with the approved EAL scheme. As a result, the licensees ability to declare an Alert was degraded during this period.

Additional Tracking Items

INSPECTION RESULTS

Failure to Establish Required Compensatory Measures When Equipment Important to Emergency Response was Non-Functional Cornerstone Significance Cross-Cutting Report Aspect Section Emergency Green [H.2] - Field 71111.15 Preparedness NCV 05000498/2023004 -01 Presence Open/Closed The inspectors identified a Green, non-cited violation of 10 CFR 50.54(q)(2) which requires that operating nuclear power plant licensees follow and maintain the effectiveness of an emergency plan that meets the requirements in Appendix E of 10 CFR 50, and the planning standards of 10 CFR 50.47(b), including 10 CFR Part 50.47(b)(4), relative to maintaining an emergency classification/action level scheme. Specifically, from July 19, 2023, to July 24, 2023, the licensees response to the loss of the control room area radiation monitor, RT-8066, failed to restore capability to classify emergency action level (EALs) RA3, Radiation Levels that impede access to equipment necessary for normal plant operation, cooldown or shutdown, whic h would rely on monitoring the control room area radiation monitor consistent with the approved EAL scheme. As a result, the licensees ability to declare an Alert was degraded during this period.

Description:

On June 18, 2023, the licensee performed work authorization number (WAN)653108 to change the air filter in containment atmosphere radiation monitors, RT-8010A and RT-8011. The licensee completed the filter change, performed post maintenance channel chec ks, and returned the radiation monitors to service.

On July 19, 2023, shortly after maintenance was completed, the primary and alternate communication ports from RT8011 that provide input into RM -11, Radiation Monitoring -

Computer Program, and RM -23, Control Room Radiation Monitoring Panel, failed. This caused indications on RM-11 and RM-23 to freeze. The licensee began troubleshooting RT-8011 under WAN 692724. During troubleshooting activities, the affected radiation monitor loop lost communication, subsequently causing the licensee to declare approximately 23 radiation monitors non-functional, including the control room area radiation monitor, RT-8066.

Licensed operators followed 0POP04-RA-0001, revision 44, Radiation Monitoring System Alarm Response, and notified the Emergency Response Organization via email of the non-functional radiation monitors.

Through continued troubleshooting, the licensee was able to restore RT-8011, and most of the radiation monitors impacted by the failure of the radiation monitor loop, to a functional status. RT-8066 was not successfully restored and remained in a non-functional status.

On July 24, 2023, the inspectors identified that RT-8066 was listed in Procedure 0EPM01-IP-0004, revision 0, Equipment Important to Emergency Response, as requiring the implementation of compensatory measures if it was non-functional. Required compensatory measures for the failure of RT-8066 included actions to monitor other functional radiation monitors in the building. The inspectors queried the licensee to verify if they had implemented the required compensatory measures and found that they had not been implemented since July 19, 2023. This resulted in the licensees degraded ability to declare EAL Alert RA3, Radiation Levels that impede access to equipment necessary for normal plant operation, cooldown or shutdown. The licensee immediately implemented the required compensatory measures, thereby restoring their EAL scheme, and declared RT-8066 non-functional in their Operability Assessment System (OAS).

The licensee determined that the u nit supervisor recognized RT-8066 as equipment important to emergency response when it became non-functional on July 19, 2023, but the crew did not make an entry into the OAS at that time. With the OAS not being updated to reflect the correct nonfunctional status of RT-8066, subsequent watch teams remained unaware of RT-8066s non-functional condition. Consequently, the required compensatory measures were not implemented from July 19 to 24, 2023.

Corrective Action References: The licensee entered these issues into the corrective action program with condition report CR-2023-7042.

Performance Assessment:

Performance Deficiency: The licensees failure to implement required compensatory measures for the failed control room area radiation monitor in accordance with the emergency plan was a performance deficiency.

Screening: The inspectors determined that the performance deficiency was more than minor because it was associated with the Emergency Response Organization Performance attribute of the Emergency Preparedness Cornerstone and adversely affected the cornerstone objective of ensuring the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency.

Specifically, compensatory measures were not established upon the loss of the control room area radiation monitor resulting in degraded ability to declare an Alert.

Significance: The inspectors assessed the significance of the finding using NRC Inspection Manual Chapter 0609, Appendix B, "Emergency Preparedness Significance Determination Process," dated September 22, 2015. The inspectors determined the finding to be of very low safety significance (Green), consistent with Figure 5.4-1, because it would have resulted in an Alert being declared in a degraded manner.

Cross-Cutting Aspect: H.2 - Field Presence: Leaders are commonly seen in the work areas of the plant observing, coaching, and reinforcing standards and expectations. Deviations from standards and expectations are corrected promptly. Senior managers ensure supervisory and management oversight of work activities, including contractors and supplemental personnel.

Specifically, licensee shift management did not ensure the Operability Assessment System remained current per procedure 0POP01-ZO-0011, Operability, Functionality, and Reportability Guidance, revision 18, which states, the Shift Manager/Unit Supervisor is responsible for ensuring the Operability Assessment System remains current. This led to inadequate shift turnover and continued failure to implement required compensatory measures.

Enforcement:

Violation: Title 10 CFR 50.54(q)(2) requires that a holder of a nuclear power plant operating license follow and maintain the effectiveness of an emergency plan that meets the requirements of Appendix E of this part and the planning standards of 10 CFR 50.47(b).

Furthermore, 10 CFR Part 50.47(b)(4), requires that a standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee.

Contrary to the above, from July 19, 2023, to July 24, 2023, upon loss of the control room area radiation monitor, RT-8066, the licensee failed to ensure that the standard emergency classification and action level scheme, as approved by the NRC for use by the licensee, was in use and maintained the effectiveness of the emergency plan. Specifically, the licensee failed to implement compensatory measures for the failed radiation monitor, which degraded the licensees ability to declare emergency action level off-normal event RA3, Radiation Levels that impede access to equipment necessary for normal plant operation, cooldown or shutdown.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
