Description
Summary:	The results of investigations of the solidification of pulps of filter materials and slags, produced during the operation of the Leningrad nuclear power plant, by incorporating them into inorganic binding materials are presented. Slag-cement binder (mixture of finely milled metallurgical slag with Portland cement) was used as the matrix material. The solution of sodium hydroxide and sodium silicate served as the solidifying liquid. The water binding ratio (from 0.54 to 0.63) gave good fluidity in cement test in all cases. Slag-cement binder and metallurgical slag were used for solidifying slags from bottoms containers. Bentonite clay was added to the binder to localize the super(137)Cs present in the wastes. It is shown that solid compounds containing up to 32 mass% filter-materials pulp or 36-77 mass% slags can be obtained by using as the binder metallurgical slag or a mixture of metallurgical slag with Portland cement. The quality of the compounds (mechanical strength, water resistance, leach rate of radionuclides) satisfy the regulatory requirements.
