| Title | Failure to Follow Procedural Requirements for RWCU System Fill and Vent |
| Description | A finding of very low safety significance and associated non-cited violation of Technical Specification 5.4, Procedures, was self-revealed when the licensee failed to adhere to procedural requirements during the filling and venting of the reactor water cleanup (RWCU) system. Specifically, on April 26, 2013, valves 1G33-F008A and F556A were left in the open position, contrary to the requirements of step 7.16.9 of procedure SOI-G33, revision 36, and resulted in the RWCU system being aligned to the condensate transfer and storage system. This valve misposition event also resulted in the TS 3.6.1.3 inoperability of the containment isolation valve 1P11F0545. Upon discovery of the condition, the licensee promptly corrected the error and the entered the condition into its corrective action program as condition report 2013-07483, and performed an apparent cause evaluation. The inspectors reviewed Inspection Manual Chapter (MC) 0612, Appendix B, Issue Screening, and determined that the issue was more than minor because it was associated with the Barrier Integrity Cornerstone attribute of configuration control and adversely affected the cornerstone objective of providing reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. The inspectors determined that the finding was of very low safety significance (Green) in accordance with IMC 0609, Appendix A, Significance Determination Process. This finding has a cross-cutting aspect in the area of human performance, work practices, for the licensees failure to successfully incorporate human error prevention techniques, such as self and peer checks. |
