| Title | Failure to Enter Technical Specifications for CHREAFS |
| Description | The inspectors identified a Green NCV of Technical Specification (TS) 3\'7.8.2\'f
StanOOV Gas Treatment System and Control Room High Efficiency Air Filtration Syste (CRHEAFS),\" for Entergy\'s failure to enter and perform the actions prescribed in TS afte the Control Room Envelope (CRE) was breached during work on a vital area door into th CRE. Entergy has since repaired the vital area door and restored the CRE. This finding was more than minor because it was associated with the Human Performanc attribute of the Barrier Integrity cornerstone (maintain the radiological barrier function of th control room) and adversely affected the cornerstone objective to provide reasonabl assurance that physical design barriers protect the public from radionuclide release caused by accidents or events. Specifically, the inoperable CRE could affect the operator\' ability to occupy the control room under adverse radiological, chemical, or smoke condition while responding to an event. IMC 0609, \"Significance Determination Process,\" Attachmen 0609.04, \"Phase 1- Initial Screening and Characterization of Findings,\" was used t evaluate the impact of the finding on loss of operability or functionality of the CRE an CHREAFS, and it was determined that further evaluation was required since the finding ha the potential to impact the control room envelope due to the effects of smoke and toxic gas As a result of this screening, a Phase 3 evaluation was conducted by a Senior Reacto Analyst (SRA). The SRA conducted a qualitative evaluation and determined the risk impac on control room habitability, due to this finding, from smoke and toxic gas to be lo (Green). Specifically, the Pilgrim Station Individual Plant Examination for External Event (IPEEE), sections 5.3.3 and 5.3.4, identified that the overall risk from on-site and off-sit chemical release was low The inspectors determined that this issue had a cross-cutting aspect in the Work Contro component of the Human Performance cross-cutting area. Specifically, Entergy did no plan and coordinate work activities affecting the CRE such that interdepartmenta coordination assured plant and human performance. In this case, Operations was no made aware that Maintenance would be working on the control room vital door (Section 1R15) |
