  • Radioactive waste processing method
    Patent number: 10629316
    Abstract: Provided is a fission product processing method for selectively transmuting only a long-lived radionuclide from fission products. The method for processing radioactive waste includes the step of extracting, from the radioactive waste, the isotopes without isotope separation, the isotope elements including radionuclides of fission products and having a common atomic number, and the step of irradiating the isotopes with high-energy particles generated by an accelerator to produce nuclear transmutation of a long-lived radionuclide of the radionuclides into a short-lived radionuclide with a short half-life or a stable nuclide re-utilizable as a resource.
    Type: Grant
    Filed: March 22, 2016
    Date of Patent: April 21, 2020
    Assignee: RIKEN
    Inventors: Reiko Fujita, Hideaki Otsu, Teiichiro Matsuzaki, Hiroyoshi Sakurai, Susumu Shimoura, Koji Mizuguchi, Hiroyuki Oigawa, Masaki Ozawa, Koji Nitta
