China prepares to test thorium-fuelled nuclear reactor
Scientists are excited about an experimental nuclear reactor using thorium as fuel, which is about to begin tests in China. Although this radioactive element has been trialled in reactors before, experts say that China is the first to have a shot at commercializing the technology.
The reactor is unusual in that it has molten salts circulating inside it instead of water. It has the potential to produce nuclear energy that is relatively safe and cheap, while also generating a much smaller amount of very long-lived radioactive waste than conventional reactors.
Construction of the experimental thorium reactor in Wuwei, on the outskirts of the Gobi Desert, was due to be completed by the end of August - with trial runs scheduled for this month, according to the government of Gansu province.
[...] When China switches on its experimental reactor, it will be the first molten-salt reactor operating since 1969, when US researchers at the Oak Ridge National Laboratory in Tennessee shut theirs down. And it will be the first molten-salt reactor to be fuelled by thorium. Researchers who have collaborated with SINAP say the Chinese design copies that of Oak Ridge, but improves on it by calling on decades of innovation in manufacturing, materials and instrumentation.
