SCRIBA, N.Y. (AP) — The Nine Mile Point 2 nuclear plant on Lake Ontario has been taken off-line after pumps that circulate water through the reactor shut off while being shifted to a lower speed.
Constellation Energy Nuclear Group spokeswoman Jill Lyon says the plant will remain off-line until all repairs are made and verified.
The shutdown occurred Monday morning. The company said the Unit 1 reactor was not affected and remains at 100 percent power.
Lyon said Nine Mile 2 had been operating at about 78 percent power since last Tuesday as crews made repairs to the feed water heating system. As part of that work, operators reduced power further to help with the repairs, and when they shifted the pumps to a slower speed both pumps shut down.
