| Title | Licensee-Identified Violation |
| Description | Licensee Event Report (LER 2-2014-001-00) was submitted following the licensees discovery that Sequoyah Unit 2 operated in a condition prohibited by Technical Specifications (TS). During mode 1 operation, train B containment purge had been operated without the minimum required operable radiation monitoring channels. TS Limiting Condition for Operation (LCO) 3.3.3.1 and TS LCO 3.3.2 required with less than the minimum channels operable, plant operation may continue provided the containment purge supply and exhaust valves are maintained closed. Contrary to the above during plant operations from April 8 and April 28, 2014, train B containment purge supply and exhaust valves were opened to place purge in service three times with containment purge air exhaust radiation monitors (SQN-2-RM-090-130 and SQN-2-RM-090-131) being incorrectly aligned to train A purge. This was licensee identified and entered into the CAP as PER 878321. The finding was screened using Inspection Manual Chapter (IMC) 0609, Significance Determination Process, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, Exhibit 3 Barrier Integrity Screening Questions and determined the finding to be of very low safety significance (Green) because it does not represent an actual open pathway in the physical integrity of reactor containment, containment isolation system, and heat removal components, or involve an actual reduction in function of hydrogen igniters. |
