An NRC-identified
Severity Level IV NCV of
10 CFR 50.72(b)(3)(v) was identified for the licensees failure to make a required non-emergency eight hour notification for a loss of the emergency
AC power path function. On December 7, 2015 Oconee Nuclear Station Unit 3 experienced a loss of the emergency
AC power path function for approximately 21 minutes. The licensee entered this issue into their corrective action program as NCR 01981762 and will evaluate their internal reportability procedures regarding the
time of discovery. The failure to make an eight hour non-emergency report for a loss of the emergency
AC power path function per
10 CFR 50.72(b)(3)(v) was a performance deficiency. This performance deficiency impacted the ability of the NRC to perform its regulatory oversight function and was dispositioned using traditional enforcement. This violation was assessed using Section 2.2.4 of the NRCs
Enforcement Policy, revised February 4, 2015. Using the example listed in Section 6.9.d.9, A licensee fails to make a report required by
10 CFR 50.72, the issue was determined to be a
Severity Level IV violation. In accordance with
IMC 0612, because this violation involved traditional enforcement and does not have an underlying technical violation that would be considered more than minor, a cross-cutting aspect was not assigned to this violation.
