Power plant to reopen after $4 billion in upgrades

NEW YORK — A power plant operated by a New York City-based company will reopen after more than $4.5 billion in improvements were completed last week.

The plant in Westchester County, N.Y., was built by PowerStream Corp., which was purchased in 2013 by New York Power & Light Corp. The plant is owned by a consortium of investors including GE, IBM and The Reactor Group.

GE, which owns more than 30 nuclear reactors, said in a statement that it is “excited to see the return to full operational capacity.”

GE said it would begin installing the new, larger containment walls on its reactor site, which were originally installed in 2006.

GE said the new containment walls will help meet new requirements for containment of the reactor core.

GE and New York’s Department of Environmental Protection have not yet announced any shutdowns.

GE said that in order to meet the new requirements, it is providing the following upgrades to the plant: a new containment wall to protect the plant’s reactor core, new control rods to protect containment, and improved control rods and pipes.

GE also said it is upgrading the cooling system.

New York Power and Light said it was able to begin installing all of the necessary new containment rods and piping at the plant last week, and is working with GE to ensure that they are installed on time and in a timely manner.

The plant has been operating without interruption since May 2016, when a leak at a leak-suppressing system caused a partial meltdown of a reactor core at the facility.

The explosion at the Fukushima Daiichi nuclear plant, which was the worst accident in Japanese history, resulted in the deaths of over 300 people and destroyed hundreds of buildings and hundreds of kilometers of coastline.
