Buchanan -- Indian Point’s Unit 3 nuclear power plant returned to service this afternoon, generating electricity a day after control room operators safely and manually shut down the unit after observing fluctuating water levels inside a steam generator.
Operators determined that one of the unit's three condensate pumps, which is part of the system that feeds water into the plant's steam generators, automatically shut down while the unit was operating at full power, causing water levels inside the steam generator to fluctuate.
The three condensate pumps are located on the non-nuclear side of the plant. The unit is operating safely on two condensate pumps while engineers and mechanics repair the third.
Unit 2 continues operating at full power and has been online for 478 continuous days.
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 and supply about 25 percent of power used annually by homes, business and public facilities in New York City and Westchester County.
