Title: Method and device for treating radioactive waste
Inventor: TOYOHARA NAOMI
IPC: G21F9/28
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To solidify radioactive wastes stably, obtain the stability of them for a long term, improve the integrity of it and reduce the treatment time and cost by soaking the radioactive wastes in an alkaline solution before the solidifying treatment of them or carrying out a heating pretreatment after the soaking of them. SOLUTION: The concentration of cement-saturated water is regulated by adding an alkaline metal element to it so that the composition will be that of water in cement and in the disposal environment. In this solution, ion exchange resin is soaked beforehand (S1). Moreover, though the heating temperature to accelerate the reaction speed may be determined by the time permitted by the time needed for the ion exchange reaction and treatment processes because much time is taken for the exchange reaction, it is heated over 70 deg.C in order to shorten the treatment time (S2). In a boiling state, especially, 30 minutes are sufficient for the treatment time. Notably, the alkaline metal element has only to be added to the cement-saturated water so that the concentration of the treatment liquid will be 0.4mol/l in the total element concentration.
