Indian Point 3 has returned to service, according to plant owner Entergy, which says the plant was back online as of 9 p.m. Friday evening. 

Control room operators took the IP3 offline earlier this week to repair a leak from a pipe that carries non-radioactive river water to the plant.

The river water contained in the pipe is used to control components in the turbine building located on the non-nuclear side of the facility.

The pipe leak had been located outdoors between the river and the building that houses the turbines and generator.

Up until the repairs, Indian Point's Unit 3 had been online for 163 straight days. Unit 2 has been online for 91 continuous days. 

The Indian Point nuclear power plants generate 2,000 megawatts of electricity for homes, businesses and public facilities in Westchester and New York City.
