  • Radioactive chemical waste treatment apparatus
    Patent number: 11735329
    Abstract: The present invention relates to a radioactive chemical waste treatment apparatus including an adsorption unit including an radioactive chemical waste adsorption member for adsorbing and separating radioactive chemical wastes from radioactive chemical waste-containing fluid, and a regeneration unit which is in fluidic communication with the adsorption unit and is for regenerating the radioactive chemical waste adsorption member by desorbing the radioactive chemical wastes from the adsorption member with the radioactive chemical wastes adsorbed thereonto, and to a radioactive chemical waste treatment method including (A) adsorbing radioactive chemical wastes onto a radioactive chemical waste adsorption member and separating the radioactive chemical wastes from a radioactive chemical waste-containing fluid, and (B) desorbing the radioactive chemical wastes from the radioactive chemical waste adsorption member with the radioactive chemical wastes adsorbed thereonto, and regenerating the radioactive chemical wast
    Type: Grant
    Filed: October 14, 2020
    Date of Patent: August 22, 2023
    Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTE
    Inventors: Sang Eun Bae, Hwa Kyeung Jeong, Dong Woo Lee, Tae Hong Park, Jei Won Yeon, Kun Ho Chung, Sang Ho Lim, Jai Il Park, Wan Sik Cha, Byung Man Kang
  • Method for measuring radioactivity of radioactive waste
    Patent number: 11598887
    Abstract: The present invention relates to a method for measuring radioactivity of radioactive waste, the method comprising an adsorption step (A) of selectively adsorbing a radioactive substance comprising at least one from among radioactive iodine and radioactive cesium from radioactive waste containing radioactive substances on an adsorption member for adsorbing a radioactive substance, and a measurement step (B) of measuring radioactivity of the radioactive substance.
