Diamond Batteries Could Use Nuclear Waste to Generate Electricity for Millennia

Diamond Batteries Could Use Nuclear Waste to Generate Electricity for Millennia

Nuclear waste takes thousands of years to decay. But that long-lived radioactivity could be exactly what makes these nuclear waste diamond batteries last for millennia. Researchers at the University of Bristol have used graphite, the waste product of nuclear reactors, to develop a man-made diamond which produces electricity when placed in close proximity to a radioactive source. Although these batteries produce only a small amount of current, they offer an incredibly long battery life of thousands of years. Making Use of Nuclear Waste Nuclear reactors need graphite blocks to control heat flow and nuclear reactions. When exposed to radioactive uranium rods, the graphite blocks gradually become radioactive, as well. When a nuclear plant gets decommissioned, graphite blocks are one of the main radioactive waste products which need to be handled. Carbon-14 is the radioactive v...
