BRIDGMAN, Mich., March 11, 2011 – Indiana Michigan Power’s Cook Nuclear Plant Unit 1 will power down late today in preparation for a planned maintenance outage that will take the unit off-line beginning early March 12. The primary purpose of the outage is to repair the main generator hydrogen seal system.
Although a mid-cycle shutdown to make the repair was not required, taking the unit off-line supports AEP’s conservative approach to maintaining safety and reliability at Cook Plant. The unit will be at zero percent power while the hydrogen seal system work is in progress, however the reactor will remain at full temperature and pressure, ready to return to full power as soon as the repairs are complete.
"We have taken the time up front to develop an outage plan that puts safety first, and maximizes opportunities for repairs and maintenance while minimizing the amount of time the unit will be off-line," said Joel Gebbie, Cook Nuclear Plant Site Vice President.
At full capacity, the 1,030-net MW Unit 1 and 1,077-net MW Unit 2 combined produce enough electricity for more than one and one half million average homes.
