Call it the great thorium divide: Thorium supporters and thorium critics do not agree over claims that thorium is an alternative nuclear fuel that could ensure a better future for the planet. Nonetheless, interest continues in thorium as a safer and abundant alternative to uranium. On the side of thorium, the latest call for action has come from Hans Blix, the former UN weapons inspector and former Swedish foreign minister. Urging nuclear scientists to develop thorium as a new fuel, Blix also called on the nuclear industry to start powering reactors with thorium instead of uranium. Blix said that the radioactive element may prove much safer in reactors than uranium and it is also more difficult to use thorium for the production of nuclear weapons.
