Robert Alvarez of the Institute for Policy Studies has prepared a power point presentation (click here for .pptx version; click here for .pdf version) re: the many costs, risks, and liabilities of irradiated nuclear fuel "interim storage" -- most to all of which, the public will be burdened with.
The U.S. Environmental Protection Agency (EPA) has acknowledged that highly radioactive irradiated nuclear fuel remains hazardous for a million years. Thus, it must be kept isolated from the living environment for that entire time period. Otherwise, a catastrophe would unfold. This applies to "interim storage," whether on-site (in pools or dry casks) at the atomic reactors where it was generated in the first place, as well as to away-from-reactor storage, and even permanent disposal, sites.
