| Title | Inadequate Procedure for Testing the Main Steam Safety Valves |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure of the licensee to have documented instructions of a type appropriate to the circumstances for testing the main steam safety valves. Specifically, the procedure for testing the main steam safety valves did not provide direction to declare the valves inoperable when applying pressure to the lifting device. As a result, the licensee failed to declare the main steam safety valves inoperable during testing. The licensee entered the finding in the corrective action program as Condition Report CR-2013-002947. The finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the procedure did not provide guidance to declare a main steam safety valve inoperable with the test rig installed. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding was determined to be of very low safety significance because the finding was not a design or qualification deficiency; did not represent an actual loss of safety function of a system or train; and did not result in the loss of one or more trains of non-technical specification trains of equipment. The inspectors determined that the finding was not representative of current licensee performance and no cross-cutting aspect was assigned. |
