Reactor Type: [1] GE-4 Last Modification: 09/27/2012 Containment Type: MARK I NRC Notified by: JORGE O'FARRILL Notifications: RONALD BELLAMY R1DO HQ Ops Officer: MARK ABRAMOVITZ PART 21 GROUP Emergency Class: NON EMERGENCY 10 CFR Section:

21.21 (d)(3)(i) DEFECTS AND NONCOMPLIANCE Unit Scram Code RX Crit Init Power [Initial RX Mode Curr Power Current RX Mode 1 N Yes 92 Power Operation 100 Power Operation PART-21 REPORT - FAULTY MASTER TRIP UNITS, SLAVE UNITS, AND RESISTANCE TEMPERATURE DETECTORS "On September 27, 2012, the Site Vice President was notified that a 10CFR21 evaluation of thirteen (13) reworked Master Trip Units, Resistance Temperature Detector Units, and Slave Units supplied by Rosemount Nuclear Instruments, Inc. (Rosemount) determined that a non-compliant condition involving a basic component existed.

"Rosemount informed James A. FitzPatrick Nuclear Power Plant (JAF) that 13 reworked Master Trip Units, Resistance Temperature Detector (RTD) Units and Slave Units were received at JAF which did not comply with their rebuild repair specification. Specifically, epoxy was not applied under certain resistors as required. In accordance with JA FitzPatrick plant procedures, this condition was determined as a 10CFRPart 21 condition involving a defect in a basic component.

"As noted by an engineering review, some of the applications for the trip units require them to energize to perform the associated safety functions. Therefore, a failure occurrence by an installed non-conforming unit could potentially have an adverse affect on the associated systems' safety/accident mitigation functions.

"JAF verified that none of the 13 deficient units were installed in any plant systems. Therefore, this condition had no actual safety consequences as the deficiency was identified by Rosemount prior to installation. The 13 units that were received at JAF without the epoxy have been returned to Rosemount for the addition of the epoxy and have subsequently been reworked and returned to JAF.

"This notification is made pursuant to 10CFR21.21(d)(3)(i)."
