Nuclear waste materials are not being used for violent purposes as the environmentalist propaganda would have the population believe.
Fifty percent of the nuclear energy being produced in the U.S. is now coming from dismantled Russian nuclear warheads. The environmental movement is going on about how terrible it will be if someone does something destructive with these materials. Well, actually the opposite is occurring: all over the world, people are using former nuclear-weapons material for peaceful purposes—swords into plowshares. This constant propaganda about the cost of nuclear energy—that's just activists looking for the right buttons to push, and one of the key buttons to push is to make consumers afraid that their electricity prices will go up if nuclear energy is built. In fact, it's natural gas that is causing [energy] prices to go up. (Zakaria)

The nuclear waste can be reused, and the part that is not can be safely deposited in a remote location.
Actually, industry solved that problem decades ago. Spent fuel is removed from the reactor. The reusable portion is recycled by separating it and re-using it; the remainder is placed in either interim or long-term storage, in remote locations such as Yucca Mountain. Other countries, including France, safely do this every day. Politicians and bad public policy prevent it from occurring in the U.S.

By enacting DUPIC processing, the waste from light water reactors can be used to fuel heavy water reactors (CANDU reactors)—solving waste problems.
Myung Seung Yang of South Korea's atomic energy institute and his fellow nuclear scientists have spent the past 15 years exploring ways of using Candu reactors to recycle highly radioactive waste, or "spent fuel," from a majority of the world's nuclear reactors.
The heavy-water reactor technology that lies at the heart of Candu's design can, with some technical tinkering, directly use waste fuel from most rival light-water reactors. The long-term implications, if DUPIC processing can be done safely and economically, are potentially enormous. There are hundreds of pressurized light-water reactors (PWRs) around the world being used to generate electricity and propel submarines and aircraft carriers.

In the United States alone, two-thirds of the 104 reactors in operation are based on PWR designs, according to the U.S. Energy Information Administration. With DUPIC processing, that waste can be turned into a reusable fuel. This can significantly reduce a country's dependence on uranium, which many analysts predict will rise above $100 (U.S.) per pound by the end of next year - a tenfold price increase since January 2001. Perhaps most important, the spent light-water fuel that eventually comes out of a Candu reactor will contain less toxic material than the fuel that goes in, shrinking the amount of radioactive waste that must ultimately go into long-term storage. "The DUPIC fuel cycle could reduce a country's need for used PWR fuel disposal by 70 per cent while reducing fresh uranium requirements by 30 per cent," according to the World Nuclear Association. DUPIC process is also "proliferation resistant," meaning there is no chemical separation of the spent uranium's more dangerous components, primarily plutonium, which could be used by extremists or rogue nations to produce nuclear weapons. AECL estimates that waste fuel from three light-water reactors would be enough to fuel one Candu.

The DUPIC technique has certain advantages:
No materials are separated during the refabrication process, uranium, plutonium, fission products and minor actinides are kept together in the fuel powder and bound together again in the DUPIC fuel bundles.
A high net destruction rate can be achieved of actinides and plutonium.
Up to 25% more energy can be realised compared to other PWR used fuel recycling techniques.
And a DUPIC fuel cycle could reduce a country¹s need for used PWR fuel disposal by 70% while reducing fresh uranium requirements by 30%. (World Nuclear Association June 2008)
