NRC CAL – NOV (White)

On June 22, 2015, the NRC issued a Notice of Violation associated with a White Significance Determination Process finding to Susquehanna Nuclear, LLC. The finding was associated with the failure to implement the 15-minute assessment, classification, and declaration period for a potential loss of Reactor Coolant System (RCS) barrier emergency action level (EAL) at the Susquehanna Steam Electric Station (Susquehanna), Units 1 and 2. Specifically, Susquehanna interpreted the 15-minute assessment, classification, and declaration clock to start when operator actions were, or were expected to be, unsuccessful in isolating an RCS leak rather than upon the time when the EAL thresholds were exceeded. Susquehanna's incorrect interpretation of the 15-minute assessment and declaration period degraded its ability to make a timely Site Area Emergency declaration. The Notice of Violation involved the failure to comply with the requirements of 10 CFR 50.47(b)(4),"Emergency Plans," 10 CFR 50.54(q)(2), "Conditions of License," and 10 CFR 50, Appendix E, Section IV.C.2., "Emergency Planning and Preparedness for Production and Utilization Facilities."
