Direct-pour cementation of nuclear power plant bottoms

The possibility of cementing nuclear power plant bottoms and storing the compound obtained in direct-pour cells is examined. The results of development work on a similar technology for solidifying medium-level liquid wastes from radiochemical production at the Industrial Association Mayak are shown. Experimental results on solidification of nuclear power plant bottoms using the prescriptions developed are presented. The flowability, water separation, and heat emission during solidification of cement solutions as well as the strength and water- and freeze-resistance of the solidified compound are determined. The proposed mix ensures that the cement compound with the solidified, nuclear power plant bottoms meets the technological and normative requirements.
