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.
