A
Severity Level IV non-cited violation (
NCV) was identified for implementing a change which decreased the effectiveness of the
emergency plan without prior NRC approval, contrary to the requirements of
10 CFR 50.54(q). The change involved Emergency Action Level 4.7.U.2.1 classification of Natural Disasters, Hazards and Other Conditions Affecting Plant Safety
The finding was evaluated using the NRCs
Enforcement Policy because licensee reductions in the effectiveness of its
emergency plan impact the regulatory process. This finding has greater than minor significance in that the change extends the event time allowed prior to appropriate emergency classification of a natural disaster which could adversely affect the performance of both onsite and offsite emergency actions. The finding was determined to be a non-cited
Severity Level IV violation because it involved licensee failure to meet an emergency planning requirement not directly related to assessment and notification.
