Entergy Plans Maintenance Shutdown of Indian Point 2 Nuclear Power Plant
Buchanan, N.Y. – Control room operators will remove Indian Point’s unit 2 nuclear power plant from service this evening in order to replace three high voltage bushings on a main electrical transformer.
There are two main electrical transformers at unit 2, located outdoors in a non-nuclear area of the plant. Transformers increase voltage for transmission onto the electrical grid. Transformer bushings connect the transformer to the overhead lines that carry electricity to the grid.
In November one of unit 2’s two main electrical transformers failed, caused by a defect in one of its high-voltage bushings. Entergy is replacing the bushings, which are similar to those that failed, on the second transformer as a precautionary measure. There presently is no indication of a potential failure.
Unit 3 continues operating at full power and has been online for 43 continuous days since returning to service following a refueling shutdown.
Unit 2 will have operated for 178 continuous days prior to tonight’s shutdown.
Indian Point Energy Center, in Buchanan, N.Y., is home to two operating nuclear power plants, unit 2 and unit 3, which generate approximately 2,000 megawatts of electricity for homes, businesses and public facilities primarily in New York City and Westchester County.
