CONGRESSMAN PETE VISCLOSKY is head of the House Energy & Water Subcommittee which controls the purse strings for MOX.
Pick up the phone today and tell Rep. Visclosky whether you think the dead-end MOX boondoggle should continue to drain our tax dollars.
You may wish to mention that there are better alternatives for plutonium disposition through plutonium immobilization and that the MOX program has fallen apart with the failure of the MOX fuel test and subsequent cancellation of the contract with Duke Power to use MOX in its reactors.
MOX is nuclear reactor fuel containing plutonium oxides mixed with conventionally used uranium oxides. It is called "MOX" for short.
Fifty tons of U.S. plutonium have been declared surplus and designated for disposition to prevent its use in bombs. Plutonium has a low specific activity, that is, it is not very "hot" radioactive-wise, therefore it is vulnerable to theft and the idea is to secure the plutonium with a high-radiation field. The basic idea behind MOX is to place the plutonium-laced MOX fuel in commercial nuclear reactors where the fission process will build up deadly radiation to create a radioactive barrier to theft or re-use of the plutonium.
Because MOX involves processing and trafficking of plutonium, the critical ingredient in nuclear weapons, there is widespread opposition to using plutonium as reactor fuel for proliferation reasons.
Environmental concerns about MOX range from increased unreliability in nuclear reactors to plutonium processing safety concerns and MOX waste management.
The environmentally preferred option is plutonium immobilization in the stranded high-radiation tank wastes at Savannah River Site. Encasing plutonium in the glassification process for these 35,000,000 gallons of highly radioactive wastes left over from Cold War plutonium production would solve two deep problems at once.

Both the planet Pluto and the element plutonium are named for the ancient god Pluto, ruler of the underworld and the dead.
In mythology, Pluto was an unwelcome visitor to Earth and to the ancient abode of the gods Olympus, because of his unpitying and inflexible nature.
Pluto was King of the Dead, but not Death itself; terrible, but not evil.
