MANUFACTURING METHOD FOR RADIOACTIVE WASTE PROCESSING MATERIAL, RADIOACTIVE WASTE PROCESSING METHOD, AND RADIOACTIVE WASTE BACKFILLING METHOD

摘要

PROBLEM TO BE SOLVED: To highly efficiently process a radioactive waste in an anion status in the state of controlling production of a radiolysis gas.;SOLUTION: Hydrotalcite is heated, dehydrated and decarbonated before at least one compound selected from the group consisting of ettringite, monosulfate, hydrogarnet and monocarbonate is heated and dehydrated. Then, the substance obtained by executing the above processes is used as a processing material for radioactive waste.;COPYRIGHT: (C)2010,JPO&INPIT
