Three Mile Island Unit 1 is a pressurized water reactor designed by Babcock and Wilcox. The unit is capable of generating 837 net megawatts (MW), enough electricity to power over 800,000 average American homes. Three Mile Island Unit 2 is owned by First Energy Company of Akron which was damaged during an accident in 1979 and never reopened.
