China set to begin first trials of molten salt nuclear reactor using thorium instead of uranium
Scientists in China are about to turn on for the first time an experimental reactor that's believed by some to be the Holy Grail of nuclear energy — safer, cheaper and with less potential for weaponisation.
Construction on the thorium-based molten salt reactor was expected to be finished this month with the first tests to begin as early as September, according to a statement from the Gansu provincial government.
Thorium is a metallic element with radioactive properties, close to uranium on the periodic table, which was considered as an alternative fuel source when the US was first developing nuclear energy technology in the 1940s.
The Americans even developed an experimental thorium-based molten salt nuclear reactor at the Oak Ridge National Laboratory in Tennessee, but the US shut it down and abandoned thorium in favour of uranium in the early 1970s.
The new reactor, built at Wuwei on the edge of the Gobi Desert in northern China, is an experimental prototype designed to have an output of just 2 megawatts.
