This is dubious. The cheapest way to "get rid" of weapons-grade plutonium is to dilute it as fuel in conventional reactors (so-called "MOX fuel" -- MOX for "mixed oxide", mixture of uranium and plutonium). It's not difficult. This doesn't make economic sense, and has no other benefit, but it does convert weapons-grade plutonium into non-weapons-grade plutonium; and this is politically correct. (Non-weapons grade means: too much thermal, radioactive, and neutron contamination to be practical for weapons.) This is pure politicking, unless you think (e.g.) the US Air Force is in danger of terrorist pirates stealing its nuclear weapons. The US is doing exactly this: (NNSA is the National Nuclear Security Administration) http://www.nnsa.energy.gov/mediaroom/factsheets/mox http://www.nnsa.energy.gov/mediaroom/factsheets/mox
