If you're talking about a comparison of energy sources and nuclear, we know that in the long term, to dispose of nuclear fuel, unless we use a technology such as Moltex, we will need a repository to store this. We can't get around that part.
Right now, we obviously use storage, surface side, in casks that are very robust and very safe, and that will last for a very long time.
My point about waste more generally was that when we consider other forms of energy, we're not considering the risks of what large-scale solar and the production of minerals for a lot of the other different technologies are doing to the world. We worry so much about the radiation side that we forget about the toxicity.
