| Title | Failure to Make a Non-Emergency Event Notification to the NRC and Submit Required LER Following a Loss of Shutdown Cooling Safety Function on Unit 1 |
| Description | A Severity Level IV NCV of 10 CFR 50.72(b)(3)(v) and 10 CFR 50.73(a)(2)(v) was identified by the inspectors for the licensees failure to report an event or condition that could have prevented the fulfillment of the residual heat removal shutdown cooling safety function, which is relied upon to remove residual heat from the reactor. Specifically, when attempting to place the Unit 1 shutdown cooling system in service, the common suction valve unexpectedly closed and caused a complete isolation of the system. The licensee entered this issue into its Corrective Action Program (CAP) as Issue Report (IR) 1244457, and, at the time of this report, was in the process of conducting an apparent cause evaluation to determine the causes of the occurrence and to develop corrective actions. The inspectors determined that the finding should be evaluated using the traditional enforcement process, since the failure to make a required report to the NRC had the potential to impact the agencys ability to perform its regulatory function. The finding was considered to be Severity Level IV, in accordance with the NRC Enforcement Policy. Because this violation did not affect the Reactor Oversight Process cornerstones, a cross-cutting aspect was not assigned. |
