Monticello Nuclear Generating Plant shutdown to repair reactor coolant heat exchanger

Operators at the Monticello Nuclear Generating Plant began a controlled, non-emergency shutdown of the plant at 8:20 p.m. Friday night to repair a heat exchanger in the reactor’s coolant system.

The plant is shutdown with all safety systems functioning, and workers will now make repairs, Xcel Energy stated in a news release. Pat Thompson, Xcel Energy’s site communications manager, confirmed the plant shutdown Saturday. According to Xcel, there was no release of radioactivity, and the situation poses no hazard to the public or plant workers.

During outages, Xcel Energy purchases electricity from the Midcontinent Independent System Operator or other utilities or increases electricity production at its other generating plants to ensure an adequate power supply for its customers.
