Yes, I think you're right: it could be done right, the way you explained it. But one little thing one has to remember is that we're supposedly all in favour of sustainable development. AECL is also in favour of sustainable development. The uranium reserves are not that large. They may be large in Canada, but there's the entire world that Canada is selling to. So all these people are trying to develop new types of reactors that will make more efficient use of uranium-238, as well as uranium-235, and perhaps even thorium.
So if we're talking about sustainable development, we have to keep in mind a little bit that we have children and grandchildren, and if nuclear power is that great, there should be some uranium left over for them too.
