Abstract: In order to solidify medium and low radioactive waste resins into a stable solid form to meet the disposal conditions, the solidification formula was studied by using epoxy resin as substrates with addition of appropriate curing agent, diluents and flame retardant. Experimental results show that when the formula is E-44 epoxy resin∶651 curing agent∶diluents=1∶0.53∶0.05 (38∶20∶2), and the quality tolerance is 50%, then the solidified body has the best performance, which meets the requirements of GB 14569.2. The results prove that solidifying radioactive waste resin with epoxy resin is feasible.

Key words: epoxy resin, solidification, radioactive waste resin
