BRIDGMAN, Mich., September 29, 2022 – Indiana Michigan Power’s Cook Nuclear Plant Unit 2 will begin its twenty-sixth refueling outage Saturday, October 1, at 3:00 a.m. Power on Unit 2 was reduced on Wednesday, September 28, to allow for equipment testing before the outage begins. The unit will have operated for 11,583 hours during its last cycle at a capacity factor of 97% percent, generating 13,558,332 megawatt-hours of electricity.

Cook Unit 1 remains at 100 percent. Power to customers is not expected to be disrupted by the planned Unit 2 outage. Outage duration and return to service information is not provided for competitive reasons.

In addition to refueling the reactor and performing regular maintenance and testing work, this outage will also feature upgrades to the feed water heater control system, a modification to the plant air compressor control system, and multiple piping bellows replacements on the moisture separator reheater system. Over 1,100 contracted workers will supplement the regular 1,000-person plant staff leading up to and during the outage. Nearly 9,700 maintenance, inspection and equipment modification job activities totaling 177,000 work-hours are scheduled for two daily 12-hour work shifts.
