Entergy Plans Brief Indian Point Unit 3 Removal from Service to Reconnect Transformer

This information is from : Control room operators will briefly remove Indian Point’s unit 3 nuclear power plant from service this evening in order to reconnect the plant’s auxiliary electrical transformer. The plant has been operating since March 1 after being taken out of service on Feb. 29 to disconnect the transformer for a precautionary repair.

The auxiliary electrical transformer takes electricity from the plant’s main electrical generator and reduces its voltage to power various plant equipment. Unit 3 operated between March 1 and April 10, using a separate source of electrical power for use on site while repairs to the transformer were being made.

Workers repaired a tap changer, a part of the transformer that regulates the voltage output from the transformer.

Unit 3 has been online for 41 continuous days of operation since the shutdown to remove the auxiliary transformer from service.

Unit 2 is operating at full power and has been online for 10 continuous days since completing its twentieth refueling outage on April 1.

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.
