Cook Nuclear’s Unit 2 Back In Service After Refueling, Maintenance

Unit 2 of the Cook Nuclear Plant is back in service after an 89-day refueling and maintenance outage. The outage was longer than normal due to the replacement of the main turbine and the inspection and replacement of baffle bolts, which support internal components of the reactor vessel. Cook officials say the $250 million turbine replacement project has been in the works for over five years, and they were aware the work would make the outage last longer. The life cycle maintenance work done over the past three months includes 114 upgrade and replacement projects as part of the 20-year operating license extension granted to the facility by the Nuclear Regulatory Commission in 2005.
