There are many ways to do recycling and we have 100s of years to figure it out. What we do now is doable, but its the worst possible thing.
Other forms of recycling are very viable and have much less problems and much less side streams.
The problem is of course that anti-nuclear crowed have stopped practically all technology development so they can claim all problems are solvable and nuclear should be abolished.
As everything with nuclear, we as a society barley got to first generation technology and then halted all development.
Canada is doing some create work with recycling of CANDU fuel, Moltex Energy is in development of a reactor to use that fuel and its a much better process then what the french use.
