One nuclear plant is up and running, while the other reactor is on the verge. That is what happened seven days after two of Minnesota’s three nuclear reactors ended up shut down.

Xcel Energy’s nuclear power plant at Monticello is now operating at full power — but Unit 1 of the twin-reactor at Prairie Island’s plant is still ramping up.

The two unrelated shutdowns occurred Aug. 14.

The Monticello plant began operating at full power Monday after workers repaired a leaking gasket on a structure that houses the reactor.

Unit 1 at Prairie Island was shut down after workers found exhaust leaks in the plant’s emergency diesel generators.

The two nuclear power plants supply about 30 percent of electricity in Xcel Energy’s Upper Midwest territory.

The company says no radiation released in either incident.
