| Title | Failure to Establish a Written Procedure for a Loss of Feedwater Event in Mode 3 |
| Description | A finding of very low safety significance and an associated NCV of Technical Specification 5.4.1, Procedures, was self-revealed on October 5, 2015, due to the licensees failure to establish a written procedure for combating emergencies and other significant events, as required by Regulatory Guide 1.33, Quality Assurance Program Requirements. Specifically, upon a loss of feedwater in Mode 3 (Hot Standby), which is an expected design and licensing basis event, the licensee did not have a written procedure as established by the Regulatory Guide. This issue was entered into the licensees CAP as IRs 2566239 and 2565513. The inspectors determined the finding to be more than minor in accordance with IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 7, 2012, because, it was associated with the Mitigating Systems cornerstone Procedural Quality attribute, and adversely impacted the objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the absence of a procedure(s) complicated the operator response to the loss of feedwater event in Mode 3. The inspectors determined the finding to be of very low safety significance in accordance with IMC 0609, Appendix A, The SDP for Findings at Power, dated September 7, 2012, Exhibit 2, since the inspectors answered "No" to the Mitigating Systems questions under Section A, Mitigating Systems, Structures, and Components and Functionality. The inspectors did not identify a cross-cutting aspect associated with this finding, because it was confirmed not to be reflective of current performance due to the age of the performance deficiency. |
