| Title | Both Ammonia Detectors Non-Functional on Unit 0 Train A of Control Room Ventilation |
| Description | (Opened) Unresolved Item 05000374/2015002-01: Both Ammonia Detectors Non-Functional on Unit 0 Train A of Control Room Ventilation. The inspectors identified an unresolved item (URI) concerning the failure of both Unit 0 Train A (0A) control room ventilation ammonia detectors. These detectors were previously removed from the TSs by amendment. On June 26, licensee staff identified that both ammonia detectors in the 0A Train of control room ventilation were non-functional. The inspectors identified that Amendments 61 and 42 contained language referencing these detectors. The amendments indicated that a commitment was made with respect to maintenance of these detectors. The licensee maintains a listing of current commitments, but this item was not on that list. The actual commitment predated the implementation of the licensees formal commitment tracking program. The particulars of the commitment were contained in referenced correspondence. A review of the correspondence will allow the inspectors to determine if additional regulatory action is warranted. This issue has been entered into the CAP under AR 2520223, NRC Question on Ammonia Detector Commitment. This issue is a URI pending NRC evaluation of the details found in the correspondence referenced above (URI 05000373/2015002-01, Both Ammonia Detectors Non-Functional on Unit 0 Train A of Control Room Ventilation). |
