The Indian Point nuclear plant in New York shut down automatically from full power Wednesday following an apparent generator problem.
Plant operator Entergy said in a release that the shutdown occurred at about 6 a.m., and the malfunction originated in the non-nuclear side of the plant. Unit 3 remained at full power.
A spokesman for the Nuclear Regulatory Commission told news outlets the shutdown was caused by a turbine trip likely triggered by a loss of voltage to a generator.
Both units at the plant north of New York City are roughly 1020 megawatt Westinghouse pressurized water reactors, according to the NRC. Unit 2 was first licensed in 1973.
