Chinese scientists are planning super-efficient nuclear reactors that can maximize uranium “burn” and minimize waste in the generation of electricity. [Ed: the word “burn” as used here means the depletion of fission-competent uranium-235 nuclei from a uranium fuel rod consisting mostly of uranium-238; this is a meaning completely different from the everyday meaning of the word “burn”, which implies a heat-producing chemical oxidation reaction.] If the first experimental reactor, set to be in operation by 2010, is successful, the technology could help relieve China’s uranium supply problems as the country accelerates nuclear power plant construction.
