| Title | Failure to Perform Adequate On-going Class 1E Qualification for the Qualified Display Processing System |
| Description | The team identified a Green, non-cited violation of 10 CFR 50.55a(h)(2) Protection Systems, which requires, in part, for nuclear power plants with construction permits issued after January 1, 1971, but before May 13, 1999, protection systems must meet the requirements in IEEE Std. 279-1971, Criteria for Protection Systems for Nuclear Power Generating Stations. Specifically, since approximately 1993, the licensee failed to demonstrate qualification of the Eagle 21 system, on a continuing basis, by appropriate methods for equipment whose qualified life is less than the design life of the system. This violation was entered into the licensees corrective action program as Condition Report CR 16-2214. The team determined that the failure to perform on-going qualification testing of installed Eagle 21 components whose qualified life was less than the design life was a performance deficiency. The performance deficiency was determined to be more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, inadequate on-going equipment qualification adversely affects the availability, reliability, and capability of Class 1E components to meet their safety functional requirements throughout their service lives. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, Exhibit 2, Mitigating Systems Screening Questions, the team determined the finding to be of very low safety significance (Green) because the finding was a deficiency affecting the design or qualification of a structure, system, or component, and the structure, system, or component maintained its operability or functionality. The team determined that this finding did not have a cross-cutting aspect because the most significant contributor did not reflect present licensee performance. |
