    Diamonds turn nuclear waste into nuclear batteries

    One problem with dealing with nuclear waste is that it’s often hard to tell what’s waste and what’s a valuable resource. Case in point is the work of physicists and chemists at the University of Bristol, who have found a way to convert thousands of tonnes of seemingly worthless nuclear waste into man-made diamond batteries that can generate a small electric current for longer than the entire history of human civilization.
    How to dispose of nuclear waste is one of the great technical challenges of the 21st century. The trouble is, it usually turns out not to be so much a question of disposal as long-term storage. If it was simply a matter of getting rid of radioactive material permanently, there are any number of options, but spent nuclear fuel and other waste consists of valuable radioactive isotopes that are needed in industry and medicine, or can be reprocessed to produce more fuel. Disposal, therefore is more often a matter of keeping waste safe, but being able to get at it later when needed.
    One unexpected example of this is the Bristol team’s work on a major source of nuclear waste from Britain’s aging Magnox reactors, which are now being decommissioned after over half a century of service. These first generation reactors used graphite blocks as moderators to slow down neutrons to keep the nuclear fission process running, but decades of exposure have left the UK with 95,000 tonnes (104,720 tons) of graphite blocks that are now classed as nuclear waste because the radiation in the reactors changes some of the inert carbon in the blocks into radioactive carbon-14.

    Carbon-14 is a low-yield beta particle emitter that can’t penetrate even a few centimeters of air, but it’s still too dangerous to allow into the environment. Instead of burying it, the Bristol team’s solution is to remove most of the c-14 from the graphite blocks and turn it into electricity-generating diamonds.
