TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO BLOWN FUSE
"On December 26, 2013 at 1301 EST, Nine Mile Point Unit 1 (NMP1) commenced a reactor shutdown in accordance with Technical Specification (TS) 3.2.7.c as a result of Main Steam Isolation Valve (MSIV) 111 being declared inoperable due to a surveillance test failure when power was lost to the control circuit. The cause of the power loss was a blown fuse due to a short in the test circuitry. TS 3.2.7.c requires that a normal orderly shutdown be initiated within one hour and have the reactor in cold shutdown condition within ten hours. The blown fuse was replaced, test circuit isolated, power to the control circuit restored and MSIV 111 was declared operable at 1549 EST. Power ascension is in progress."
Post maintenance operability test have been completed and the surveillance will be completed at a later time.
The licensee has notified the NRC Resident Inspector and the State of New York.
