Event Report: Blown fuse takes down New York reactor

Today’s NRC Event Notification Reports page contained a report from New York’s Nine Mile Point nuclear plant.

Yesterday afternoon, technicians were performing testing on the facility’s Unit 2 reactor when a short in the control circuit caused a blown fuse.  This led to a Main Steam Isolation Valve being declared inoperable. Operating procedure required that the unit go into a Technical Specification shutdown.

The shutdown procedure required that the plant reduce operating power over the next ten hours. Workers were able to replace the blown fuse a little less than three hours into the procedure, at which point the reactor began to ramp back up. A post maintenance operability test has been completed, and the original surveillance test, which was interrupted by the blown fuse, will be performed at a later time.
