>Where do the nuclear byproducts go currently ? Into the earth? Rivers? Oceans? No where, because there aren't any. If you meant spent fuel if it's not reprocessed it's stored as long as needed to be less dangerously radioactive. If it's reprocessed, any radioactive elements in it that aren't useful are stored and left to decay. Present storage of things like this is on-site as mentioned above, because reprocessing mostly doesn't happen. The amount of unusable material from reprocessed fuel is tiny, by the way.... even less trouble than storing the spent fuel rods, on the order of a handful of material from a whole fuel rod assembly. Power generating reactors don't give off anything but electricity, heat, and spent fuel, they are zero emissions.
