If the world was serious about nuclear non-proliferation, we would have thorium reactors everywhere already. They said a few times in the video that thorium reactors can't be used for weapons, and so they are not built. Governments have decided that we need nukes, so thorium reactors do not get funding. But if we are serious about non-proliferation, then switching to thorium reactors and controlling which new reactors get built is a much more effective strategy then the current weapon-counting efforts. Once a reactor is built and starts creating fissile material, then it is difficult to keep track of and control. But it is much harder to hide a reactor while you are building it - Iran tried and failed. So it seems to me that thorium reactors, in addition to their efficiency, low cost and low amount of radioactive waste, could also be a useful tool in enforcing nuclear non-proliferation. We've got these reactors that cannot be used to make bombs - why don't we sign treaties saying that they are the only reactors that can be built?
