One of two nuclear reactors at the Indian Point nuclear plant in Buchanan, NY, automatically shut down during testing of electrical systems.
The cause of Wednesday morning’s shutdown of Unit 2 is under investigation. The plant owner, Entergy Corporation, said the shutdown occurred as workers were testing electrical systems designed to automatically shut down the reactor if needed.
Entergy said no radioactivity released and public remained safe.
The company says its other reactor, Unit 3, remains in operation and has been online for 203 consecutive days.
Indian Point provides 2,000 megawatts of electricity to New York City and Westchester County.
Earlier this month, Indian Point 2 returned to service after workers repaired a leaking water pipe.
Entergy said the unit shut down to complete weld repairs to a pipe and to allow workers from Con Edison to test a breaker in a nearby switchyard.
Also, Indian Point 2 shut down in March for three months after the Nuclear Regulatory Commission (NRC) discovered damaged or cracked bolts during an inspection.
