Now, let us look at this deep geological disposal. Basically what we want to do is to dispose this radioactive waste and to remove it from human environment. So that we do not get affected that there is radionuclear release rates. And of course they remain within the prescribed limits.
So these are the canisters, in which you palce radionuclear waste, surrounded by a bentonite barrier and by a rock. Then there is a concrete plug. And that is sort of what happens in deep geological disposal.
