Title (EN) METHOD FOR PROCESSING RADIOACTIVE IODINE-CONTAINING FLUID
(FR) PROCÉDÉ POUR TRAITER UN FLUIDE CONTENANT DE L'IODE RADIOACTIF
(JA) 放射性ヨウ素含有流体の処理方法
Abstract:
(EN) A method for processing a radioactive iodine-containing fluid, in which a fluid containing radioactive iodine is passed through an iodine adsorbent comprising a silver-containing binderless zeolite molded body having a silver content of 50 wt.% or less to cause the iodine adsorbent to adsorb the radioactive iodine.
(FR) L'invention concerne un procédé pour traiter un fluide contenant de l'iode radioactif, dans lequel un fluide contenant de l'iode radioactif est passé à travers un adsorbant d'iode comprenant un corps moulé à base de zéolite sans liant contenant de l'argent ayant une teneur en argent inférieure ou égale à 50 % en poids pour amener l'adsorbant d'iode à adsorber l'iode radioactif.
(JA) 放射性ヨウ素を含む流体を、銀含有量が50wt%以下である銀含有バインダレスゼオライト成形体からなるヨウ素吸着剤に通過させ、当該ヨウ素吸着剤に放射性ヨウ素を吸着させる、放射性ヨウ素含有流体の処理方法。
