After the 1979 meltdown at Three Mile Island in Pennsylvania, Disney theme park designer Art Riley jokingly proposed repurposing the site as an amusement park - seen here in this concept art found recently on Ebay.Link to Justin's blog post, which also explores a German fun park on the site of an abandoned nuclear power plant.

I happened to catch this news that Unit 1 from Three Mile island (TMI-1) was shut down earlier this month for a few days "due to a grid disturbance" which probably means problems with the delivery of energy to the electrical grid. It's operating at full power now providing 850 Megawatts. (Link). Unit 2 is the reactor that had the meltdown in 1979 and as of 1993 is permanently shutdown and defueled. (Link)
