22 minutes later, much of the thorium-233 decays into an element known as protactinium-233. At this stage, it is possible to separate the protactinium-233 out from the protactinium-thorium mix. Twenty-seven days later, the protactinium-233 will have naturally decayed into uranium-233, without producing any uranium-232 that would need to be handled by large facilities. This natural process could be accelerated, the scientists note, by bombarding the elements with neutrons at each stage."The problem is that the neutron irradiation of thorium-232 could take place in a small facility,[link widoczny dla zalogowanych]," Ashley said. "It could happen in a research reactor, of which there are about 500 worldwide,[link widoczny dla zalogowanych], which may make it difficult to monitor."Based on prior experiments, the authors conclude that it would take only 1.6 metric tons of thorium to produce the eight kg of uranium-233 required to make a nuclear weapon. It would be possible to refine this much uranium-233 "in less than a year," they said."The most
