WebThe key component of nuclear waste is the leftover smaller nuclei, known as fission products. The fission process of a single atomic nucleus. Note that Krypton and … WebThe radioactive waste created in the once through nuclear fuel cycle has to be isolated from the environment for thousands of years. In addition, plutonium and other actinides, after the decay of fission products, could become targets for weapon proliferators. Furthermore, only a small fraction of the energy potential in the fuel is being used.
