Alkaline slag cement solidification method for boron-containing waste resin of nuclear power plant
The invention relates to an alkaline slag cement solidification method for boron-containing waste resin of nuclear power plant. The alkaline slag cement solidification method comprises: uniformly mixing alkaline slag, zeolite powder and silica fume to prepare a mixed material; then stirring the mixed material with water in a stirrer; then pouring the boron-containing waste resin and stirring the mixture for 30-120 seconds, then adding water glass to be stirred, and finally adding a polycarboxylate superplasticizer to prepare mixed slurry; and then pouring the mixed slurry into a solidification container. The alkaline slag cement solidification method provided by the invention has the beneficial effects that (1) the resin loading capacity is obviously increased, and when the resin loading capacity is 65%, performance requirements specified by the national standard GB14569.1-2011 can be still satisfied; (2) the setting time of the mixed slurry is adjustable, so that delayed coagulation of the mixed slurry caused by borate can be effectively avoided; and (3) the hydrating heat release of the solidification body is small, no cracks are generated on the surface of the curing body, the leaching resistance of nuclide ions is good, and the mixed slurry is good in flowing property, so that the requirement of large-size solidification can be satisfied.
