NRC CAL – NOV (White)

On September 20, 2016, the NRC issued a Notice of Violation with a White Significance Determination Process finding to Exelon Generation Company, LLC (Exelon) for a violation associated with a White Significance Determination Process finding identified during an inspection of the R.E. Ginna Nuclear Power Plant (Ginna). This White finding, an issue of low to moderate safety significance, will require additional U.S. Nuclear Regulatory Commission (NRC) inspections. The finding involves an inadvertent change Exelon made that introduced an error to the Ginna Emergency Plan. Specifically, Exelon implemented a revision to the emergency action level (EAL) table for the fission product barrier matrix that was incorrect with respect to the EAL threshold associated with a potential loss of containment barrier. This could have resulted in an untimely declaration of a General Emergency or a failure to declare a Site Area Emergency during an actual event. A Notice of Violation is included based on Exelon’s failure to meet 10 CFR Part 50.54(q)(2), which requires that a holder of a license under this part shall follow and maintain the effectiveness of an emergency plan that meets the requirements in Appendix E to this part; and for nuclear power reactor licensees, the planning standards of 10 CFR 50.47(b).
