Title
10 CFR 50.72, Immediate notification requirements for operating nuclear power reactors, section (b)(3)(v), requires, in part, that the licensee shall notify the NRC as soon as practical and in all cases within eight hours of the occurrence of any event or condition that at the
time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to: (A) shut down the reactor and maintain it in a safe condition; (B) remove residual heat; (C) control the release of radioactive material; or (D) mitigate the consequences of an accident. Contrary to the above, on August 12, 2016, the licensee experienced a loss of the essential chilled services water safety function, which is needed to mitigate the consequences of an accident, and did not notify the NRC within
8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. The licensee identified this issue and entered it into their corrective action program as
CR-WF3-2016-05188 and made the required notification on August 15, 2016. 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.
