| Title | Inadequate Procedure for a Loss of Coolant Accident Outside Containment |
| Description | A finding of very low safety-significance and associated Non-Cited Violation of Technical Specification (TS) Section 5.4.1, Procedures, was identified by the inspectors for the failure to provide adequate procedural direction to respond to a large loss of coolant accident (LOCA) outside containment. Specifically, emergency operating procedure DB-OP-02000, RPS, SFAS, SFRCS Trip, or SG Tube Rupture, was inadequate, in that, procedural direction for a large LOCA outside containment was not provided. The finding was determined to be more than minor because the failure to provide adequate procedural direction for a large LOCA event outside containment affected the cornerstone objective of providing reasonable assurance that the physical design barrier of containment is maintained to protect the public from radionuclide releases caused by accidents or events. A Phase 3 analysis was performed, which determined that the issue was of low safety-significance based on the relatively low initiating event frequency and credit for recovery. The inspectors did not identify a cross-cutting aspect associated with this finding because this was a legacy design issue, therefore was not reflective of current performance. |
