Unit 2 at the Cook nuclear power plant is now back up and running. Cook plant spokesperson Bill Schalk tells WSJM News the unit was shut down in March for a regular refueling outage. The 67 day outage featured a variety of repairs and other maintenance in the reactor.
“All the original large components on the non-nuclear side of the plant have now been replaced,” Schalk said. “We installed a new 230 ton main generator in addition to some high pressure heat exchangers and drain pumps and new digital reactor controls.”
Schalk tells us the baffle bolts have also now been replaced. With the refueling outage now done, Schalk tells us Unit 2 is well-positioned for long-term viability. It went back online early Friday and the Cook plant is running at full capacity. The next refueling outage will be on Unit 1 next spring, Each of the plant’s units must go through a refueling outage every 18 months.
