| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50.54(q)(2) requires, in part, that licensees shall follow and maintain the effectiveness of an emergency plan that meets the planning standards of 10 CFR 50.47(b). Title 10 CFR 50.47(b)(4) requires, in part, that a standard emergency classification and action level scheme is in use by the licensee. The licensees emergency plan provides for the ability to classify an alert due to a seismic event based on an alarm condition on their seismic monitoring system panel in conjunction with other indications. Contrary to the above, during four separate periods between May 16, 2012 and October 1, 2014, the licensee failed to maintain the ability to classify an alert due to a seismic event. The licensees emergency action level HA1.1, an alert due to a seismic event, required the receipt of an alarm from the seismic monitoring system. The licensee had implemented proceduralized compensatory measures when the system was unavailable that consisted of an engineering evaluation to determine whether the event met the emergency action level criteria. The licensee determined these measures would not be sufficient to allow the emergency director to classify the event within fifteen minutes. The licensee discovered this during a review of industry operating experience and submitted a notification report for a loss of major assessment capability. The violation is more than minor because it affected the ERO Performance attribute of the Emergency Preparedness cornerstone and impacted the cornerstone objective to ensure 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. Using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, and Inspection Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process, the inspector determined that the violation is of very low safety significance (Green) because the finding represented a failure to comply with planning standard (b)(4), and, using table 5.4-1, was screened as a Green finding because an emergency action level initiating condition was rendered ineffective such that an Alert would be declared in a degraded manner for a seismic event, but no Site Area Emergency or General Emergency initiating conditions were affected. The violation was entered into the licensees corrective action program as CR-2015-003129. |
