In a press release, the Union of Concerned Scientists has brought to light a U.S. Department of Energy contractor's warning that the Mixed Oxide Plutonium-Uranium (MOX) Fuel Fabrication Facility, under construction at the U.S. Department of Energy's Savannah River Site in South Carolina, could cost taxpayers more than $100 billion, and may not be functional till Fiscal Year 2100, a century after the construction project began!
UCS also emphasizes that the DOE contractor report reaffirms that immobilization -- the mixing of the excess weapons-grade plutonium back into the high-level radioactive waste from which it came in the first place -- and disposal as radioactive waste, would be quicker and cheaper than the MOX option.
Nix MOX activists have called for immobilization as the more sensible option for two decades, but their pleas have fallen on deaf ears in both Democratic and Republican administrations, as well as Congresses.
In addition to the astronomical costs, MOX undermines U.S. non-proliferation efforts. It sets a bad example for other countries to follow, of plutonium reprocessing that could easily lead to nuclear weapons proliferation.
