On this date, March 28th 1979, in Middletown Pennsylvania, the Three Mile Island Nuclear Power Plant suffered a near meltdown. The accident occurred in the Unit 2 Reactor. The Reactors were PWRs or Pressurized Water Reactors. At least it did not turn out to be what Chernobyl and the SL-1 were. What if TMI went to the point and exploded? Would Harrisburg and the surrounding areas be abandoned?
