Title | Both Trains of Containment Atmosphere Dilution System Inoperable |
Event Description | On December 18, 2015 at 1722 EST, with James A. FitzPatrick Nuclear Power Plant (JAF) operating at 100 percent power, JAF received a notification pursuit to 10 CFR 21.21(d)(3)(ii) related to Moore Industries RTD temperature transmitters. Specifically, wire insulation in T2 transformer was damaged during assembly which reduced the insulation resistance and dielectric breakdown between the windings of the transformer. This equipment is in both redundant trains (A and B) of the Containment Atmosphere Dilution (CAD) System.
Preliminary review by Operations and Engineering, which was completed on 12/18/15 at 2100 EST, determined the Part 21 results in both trains of CAD being inoperable and the applicable Technical Specification (TS) for both redundant trains of CAD being inoperable was entered. Per TS 3.6.3.2 Condition B, this places the unit in a 7-day shutdown LCO, provided the hydrogen control function is maintained. Per the TS Bases, the alternate hydrogen control capabilities are provided by the Primary Containment lnerting System, which is unaffected. The event is reportable pursuant to 10 CFR 50.72(b)(3)(v)(D), as an event or condition that could prevent fulfillment of a safety function. The licensee notified the NRC Resident Inspector. |
