Dealing with the Used Fuel (Reprocessing)

What comes out of a nuclear reactor and how and why you would want to separate the fission products from the actinides (trans-uranics). The radiotoxicity of the wastes vs time. How reprocessing has been done and is being done around the world. Discussion of why the plutonium from nuclear wastes from a light-water reactor does not make weapons-grade plutonium contrasted to that from a breeder reactor. A detailed look at the integral fast reactor, which recycles its trans-uranic wastes all inside a containment building.
