However, the radioactive wastes generated after nuclear fission takes place are the principal environmental concern. They must be well disposed of in specially designed pools and then maintained in costly dry storage containers. They are highly radioactive, hazardous to humans even with short-term exposure. The disposal and storage of these radioactive isotopes as well as the decommissioned reactors cost taxpayers more than tens of millions of dollars annually. le; the White sed Scientists are dedicated to the reuse of nuclear wastes. The researchers at the University of Bristol in the U.K. are trying to encapsulate nuclear waste within diamonds. “The radiation is locked safely away inside the gemstone, meanwhile providing a clean energy supply like a long-lasting battery,” said the head of the team. They aim at carbon-14, a radioactive isotope with a half-life of around 5,730 years and available in graphite blocks used to cool the uranium rods. By heating the blocks, scientists convert carbon-14 into a gas and then gather it to form a kind of “diamond”- since diamonds are just another form of carbon. To safely block the short-range radiation it emits, scientists suggest the most solid substance on Earth, diamond, to contain it. A diamond beta-battery comes into being as a result. carly The same as what is confronting in dealing with nuclear waste stockpiles, the diamond battery is highly-priced, too expensive to manufacture. However, researchers are still holding an optimistic attitude toward it, speculating about its possible applications in anything where
