A renewed and more uniform preparation and review process was initiated in the mid-1990s under the responsibility of a newly created Department of Nuclear Safety . If the material had detonated , then the entire plant would have been flattened.The problem with some of the radioactive isotopes created in a nuclear explosion is the long half-life . Such matter is typically enriched with heavier elements ( " metals " ) created during the nuclear life of the parent star . To pour money into a worringly dangerous processes which creates tons of nuclear waste that can onlybe hidden away undergound for future generations to deal with . The research program aims to generate fusion reaction products for various applications , including protons for creating radioisotopes for nuclear medicine and neutrons for detecting clandestine materials .
