| Title | Failure to Identify and Correct Environmental Qualification Deficiency |
| Description | The team identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to promptly identify and correct a condition adverse to quality. Following discovery of non-environmentally qualified flow transmitters installed in the train A and C residual heat removal subsystems, licensee personnel failed to document the nonconforming condition in a condition report and failed to promptly restore the flow transmitters to an environmentally qualified state. No immediate actions were required to restore compliancethe licensee had replaced the nonconforming transmitters under Work Orders 01156960 and 01150424 on August 31, 2012, and September 12, 2012, respectively. The licensee entered this performance deficiency into its corrective action program as CR 289720. The licensees failure to initiate a condition report for a non-conforming condition involving non-environmentally qualified flow transmitters installed in the train A and C residual heat removal subsystems was a performance deficiency. The performance deficiency was more than minor because it affected the design control attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609 Appendix A, Exhibit 2, the team determined the finding was of very low safety significance (Green) because the finding was a design deficiency that did not result in the loss of functionality. The inspectors determined that this finding had a cross-cutting aspect in the decision-making component of the human performance cross-cutting area because the licensee failed to demonstrate that nuclear safety was an overriding priority by using conservative assumptions when making decisions about non-conforming conditions. |
