| Title | Licensee-Identified Violation |
| Description | Title 10 CFR 50, Appendix B, Criterion V, Instruction, Procedure, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions appropriate to the circumstances. Contrary to that requirement, the work instructions were not appropriate for the circumstances for a WO executed during the September 2011 refueling outage for a containment isolation valve in that the parts list identified the wrong part number for an actuator diaphragm. On September 18, 2013, the licensee identified that the wrong part number was identified in the instructions included in WO 01324133-01, Rebuild Actuator, Regulators/Replace Elastomers, and an unqualified valve diaphragm was installed in the actuator for AOV 2RE9160A, Reactor Coolant Drain Tank to Waste Gas Compressor Inside Containment Isolation Valve. The licensee entered the issue into their CAP as IR 1560606, Unqualified Valve Diaphragm Installed in 2RE9160A in B2R16, and replaced the diaphragm with a qualified part. The valve was tested and declared operable on October 11, 2013. The work planner selected the wrong diaphragm from the model WO while preparing the work instructions for WO 01324133 and failed to ensure the part selected was qualified for the containment environment. The inspectors determined that the performance deficiency was more than minor because it was associated with the Containment Isolation attribute of the Barrier Integrity cornerstone and adversely impacted the cornerstone objective of providing reasonable assurance that the design barrier of the containment be maintained to protect the public from radionuclide releases caused by accidents or events. The inspectors screened the issue using IMC 0609, Appendix A, The Significance Determination Process for Findings at Power, Exhibit 3, Barrier Integrity Screening Questions, and determined that both questions for the Reactor Containment were answered No and therefore the issue screened as Green. |
