Three Mile Island’s 60-year shutdown: ‘More akin to a marathon than a sprint'

        July 16, 2019 The Philadelphia Enquirer | Pennsylvania | nuclear: decommissioning

Exelon's TMI Unit 1, twin of the infamous TMI2, will begin decommissioning, taking nearly 60 years and $1.2 billion. The fuel rods will be removed, cooled in spent fuel pools for 3 years, and then moved to above-ground canisters. The cooling towers will remain until 2074, all radioactive material removed by 2078, and the site turned into a green field.
