New project re ignites European interest in thorium

In contrast with the uranium plutonium cycle described above thorium reactors are fuelled with non fissile thorium and a small amount of fissile uranium 235 which starts the fission chain reaction As thorium reactors are breeder reactors once they start running there is no need to add more fissile material as it is generated within the reactor

Thorium reactors Asgard s fire

Thorium though is hard to turn into a bomb not impossible but sufficiently uninviting a prospect that America axed thorium research in the 1970s It is also three or four times as abundant as uranium In a world where nuclear energy was a primary goal of research rather than a military spin off it would certainly look worthy of
