The Cook Nuclear Plant will start its 24th refueling outage Tuesday night at 10 for Unit 2. Indiana Michigan Power began gradually reducing the power produced by the reactor on September 9 to prepare to take it offline for the work. Other projects set for the refueling outage include modifying the unit’s solid state protection system, heater drain pump mechanical seal replacements, fuse upgrades in the control room, and replacing the west motor driven auxiliary feed pump room cooling system. The length of the refueling outage is not released by Indiana Michigan Power for competitive reasons. The utility is bringing in about 1,150 contractors to supplement the 11-hundred person staff, and crews will work around the clock doing over 95-hundred maintenance, inspection, and equipment modification job activities.
