| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50.54(q)(2) requires that a holder of a nuclear power reactor operating license follow and maintain the effectiveness of an emergency plan that meets the requirements in 10 CFR Part 50, Appendix E and the planning standards of 10 CFR 50.47(b). Title 10 CFR Part 50.47(b)(4) states, A standard emergency classification and action level scheme, the bases of which includes facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures. Section 4.1 of the Palisades Site Emergency Plan states, in part, that a conservative philosophy for classification shall be used to declare the highest classification for which an EAL has been exceeded and that Palisades EALs can be found in the Site Emergency Plan, Supplement 1 EAL Wall Charts. Site Emergency Plan, Supplement 1 EAL Wall Charts requires, in part, the declaration of an Unusual Event for EAL HU 1.1 for a seismic event if identified by both: (1) earthquake felt in plant, and (2) National Earthquake Information Center. The Palisades EAL Technical Basis defines a felt earthquake as, An earthquake of sufficient intensity such that: (a) the vibratory ground motion is felt at the nuclear plant site and recognized as an earthquake based on a consensus of control room operators on duty at the time, and (b) for plants with operable seismic instrumentation, the seismic switches of the plant are activated. Contrary to the above, on May 2, 2015, the licensee control room staff declared EAL HU 1.1 without meeting the threshold criteria stated in the EAL. Specifically, the control room staff based the Notification of Unusual Event declaration on outside personnel reports and information from the National Earthquake Center, but without the consensus of control room operators on duty at the time or a valid recorded indication on the operable seismic instrumentation. The NRC determined that the EAL Overclassification, which resulted in no unnecessary protective action recommendations, was of very low safety significance (i.e., Green) as specified in IMC 0609, EP Significance Determination Process, Appendix B, Figure 5.41, Significance Determination for Ineffective EALs and Overclassification. As such the NRC determined this to be an NCV in accordance with Section 2.3.2 of the Enforcement Policy. The licensee entered this issue into their CAP as CR 201508137. |
