Under a federal measure passed 30 years ago, the spent fuel from America’s nuclear reactors is supposed to be permanently buried out in the Mojave Desert, tucked deep under a mountain, far from any population center and easily guarded.

In reality, though, that radioactive waste – tens of thousands of tons of it – is sitting in temporary storage at dozens of current and former nuclear power sites all over the country, as it has been for decades. The largest portion of it is divided among seven sites that dot the nation’s fifth-largest state: Illinois.
