| Title | Control Room Envelope Inoperable due to Unlatched Boundary Door |
| Description | The inspectors identified a non-cited violation (NCV) of very low safety significance of 10 CFR 50, Criterion XVI, Corrective Action, because Entergy personnel did not identify and correct a condition adverse to quality related to a control room envelope (CRE) boundary door. Specifically, Entergy personnel did not identify and implement adequate actions to ensure the safety-related CRE boundary door, 70DOR- 4-300-5, remained latched and able to perform its safety function. As corrective action, the foreign material that prevented the door from consistently latching was removed by Entergy personnel. The issue was entered into the corrective action program (CAP) as condition reports CR-JAF-2010-08617 and CR-JAF-2011-00407\' The finding was more than minor because it was associated with the configuration control and the barrier performance attributes specific to the radiological barrier function of the control room. The finding affected the Barrier Integrity cornerstone objective to provide 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 finding was determined to be of very low safety significance in accordance with IMC 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, based on a Phase 3 analysis. The inspectors determined the period that the door was potentially open was small relative to the technical specification (TS) allowed outage time, and therefore represented very low safety significance, considering the low probability of a design basis accident during that time period. The finding had a cross-cutting aspect in the area of problem identification and resolution within the corrective action program component because Entergy personnel did not completely and accurately identify the degraded condition of the door (P.1(a) per IMC 0310). |
