| Title | Degraded Emergency Action Level Scheme |
| Description | A finding having a significance of preliminarily White with one AV of 10 CFR 50.54(q)(2) associated with risk-significant planning standard 10 CFR 50.47(b)(4) was identified by the NRC for the licensee failure to follow and maintain the effectiveness of its emergency plan. Specifically, from February 28, 2011, until March 30, 2011, KPSs unidentified loss of System Particulate, Iodine, and Noble Gas (SPING) indication on the Plant Process Computer System (PPCS) and Radserv stations precluded action to restore the capability to classify Emergency Action Levels (EALs) RG1.1, General Emergency, and RS1.1, Site Area Emergency. The NRC believes that the KPS staff had the opportunity to identify this condition at the time of the failures. On March 30, 2011, the system engineer identified the failure during a system walk down in CR 419976, and the server and computer point were subsequently restored to service. This finding was determined to be more than minor because it was associated with the Emergency Response Organization performance attribute of the Reactor Safety Emergency Preparedness Cornerstone. This finding adversely affected the cornerstone objective of ensuring that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. This finding was evaluated in accordance with IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process. As Appendix B was revised in February 2012, the finding was evaluated using both the version in effect at the time of the violation and the current version. Under both versions, other than changing the names of the involved Section and Sheet/Attachment, there was no effect on the final outcome. The issue was determined to be a Failure to Comply. The risk was evaluated using Section 4.0 of IMC 0609 and Sheet 1, Failure to Comply, in the previous revision, and Section 5.0 and Attachment 2, Failure to Comply Significance Logic, in the current revision, along with their associated narratives. With EALs, RG1.1 and RS1.1, ineffective, the inspectors considered mitigating factors, such as alternative EALs, within the same initiating condition and determined the alternative EALs were such that an accurate declaration of the initiating condition would have been made. Therefore, the inspectors determined that no loss of Risk-Significant Planning Standard (RSPS) function existed. However, the alternative EAL classifications would have been delayed, and, therefore, the event would have been declared in a degraded manner. The finding was preliminarily determined to be of low to moderate safety significance (White) in that ineffective EALs, RG1.1, and RS1.1 existed, degraded an RSPS function, and affected the ability of the licensee to properly classify events involving a radiological release. A cross-cutting aspect (P.1(d)) was identified within the Corrective Action Program component. The failure to identify the loss of SPING indication on the PPCS and Radserv stations prevented appropriate corrective actions to address the degradation of this risk significant planning standard function. |
