The company that owns Three Mile Island’s Unit 2 reactor wants to take the next step in dismantling the shuttered plant.
TMI-2 is the site of the infamous partial meltdown in 1979 – the most serious accident at a commercial nuclear power plant in U.S. history.
In an Aug. 22 notice in the Federal Register, the Nuclear Regulatory Commission said TMI-2 Solutions is applying to change its license to say it is decommissioning the plant using the DECON method. That method involves disposing of radioactive materials at a commercial site or decontaminating materials on site.
The move is open to public comment and subject to NRC approval.
The NRC says preliminary review finds no increased risk of accidents at the site by moving to the next phase of clean up.
TMI-2 Solutions bought the reactor in 2020, betting it could profit by cleaning up the plant on a lower budget than what is in a dedicated fund. In a March report to the NRC, TMI-2 Solutions said the fund balance was $902 million as of Dec. 31, 2021. Decommissioning is estimated to cost more than $1 billion.
TMI-2 Solutions plans to finish decommissioning in 2037. It could keep control over an area that may be set aside for waste storage.
TMI-2 hasn’t produced power since the 1979 accident.
TMI’s Unit 1 reactor is owned by Exelon. It shut down on Sept. 20, 2019 because it struggled to compete with cheaper energy sources such as natural gas.
