Three Mile Island nuclear plant shutdown cost: $1.2 billion
The Three Mile Island Unit 1 nuclear reactor shutdown, which is set to begin no later than in Sept. 30, would take nearly 60 years and $1.2 billion to complete. The Nuclear Regulatory Commission is outlining Exelon Generation’s plans to decommission TMI Unit 1, whose closure the company announced in May after it became clear the Pennsylvania General Assembly would not approve a financial rescue of the state’s nuclear plants.
