SHUTDOWN REQUIRED BY TECHNICAL SPECIFICATIONS DUE TO TRANSFORMER FAULT
"This event is being reported in accordance with 10CFR50.72(b)(2)(i). On October 2, 2011, at approximately 0100 hours [EDT], the Perry Nuclear Power Plant commenced a controlled plant shutdown. The shutdown was due to the anticipated investigation and expected repair time of the Unit 1 startup transformer exceeding the Technical Specification (TS) Required Action completion time.
"On September 29, 2011, at 0529 hours [EDT] the Unit 1 startup transformer failed due to an internal fault, which required entry into TS 3.8.1 Action A.2 for one required offsite circuit inoperable. The determination has been made that the required action, which is to restore the required offsite circuit to OPERABLE status, cannot be met by the required completion time and a plant shutdown is being initiated.
"The NRC Resident Inspector has been notified."
The licensee expects to have the Unit offline between 1300-1400 hours [EDT] and plans to issue a press release.
