Like Three Mile Island, Oyster Creek was a single-unit plant with higher operating costs than multi-unit sites such as Peach Bottom, or Exelon’s … Three Mile Island Nuclear Station, Unit 1. As a result, the construction of new plants declined in the 1980s and 1990s, according to the. Within seconds of the shutdown, the pilot-operated relief valve (PORV) on the reactor cooling system opened, as it was supposed to. The facility, which is near Middletown, Pa., has been losing money, and in a statement on Wednesday, Exelon Generation, the company that owns the plant, said it would be closed by Sept. 30. Accidents like the one at Three Mile Island make it difficult for nuclear power facilities to present themselves as clean and safe, even though they do not generate planet-warming greenhouse gases. Disaster struck in the early morning hours of March 28, 1979, when water-coolant pumps failed and a reactor overheated. There is one reactor still operating on Three Mile Island in central Pennsylvania.
