Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
A METHOD FOR DISPOSING OF RADIOACTIVE WASTE WHICH COMPRISES THE STEPS OF MIXING CERAMIC MATERIALS, ADDING WATER TO THE MIXTURE, SHAPING THE MIXTURE INTO POROUS PIECES WHICH CAN BE HANDLED, PRE-FIRING THE PIECES AT TEMPERATURE SUFFICIENT TO DESTROY THE ION-EXCHANGE CAPACITY OF THE CERAMIC MATERIALS AND TO HARDEN THE PIECES AND PREVENT SLAKING ON ABSORPTION OF WATER WHILE RETAINING MAXIMUM ABSORPTIVE PROPERTIES, SATURATINGG THE PIECES WITH RADIOACTIVE WASTE MATERIAL BY ABSORPTION, DRYING THE SATURATED PIECES, AND FINALLY FIRING THE SATURATED DRIED PIECES AT TEMPERATURES SUFFICIENT TO PRODUCE COMPLETE VITRIFICATION AND TO CONVERT THE MATERIAL TO AN INSOLUBLE STATE.

Claim 3
Dependent Claim
74 words
A NEW PRODUCT OF MANUFACTURE IN THE FORM OF HARDENED PIECES WHICH CAN BE HANDLED, COMPOSED OF CERAMIC MATERIAL AND RADIOACTIVE WASTE MATERIAL ABSORBED THEREIN AND CHEMICALLY COMBINED THEREWITH IN THE FORM OF INSOLUBLE SILICATES AND MINERALS FROM WHICH THE COMPONENTS CANNOT BE LEACHED OUT BY WATER, IN WHICH THE WEIGHT OF THE RAIDIOACTIVE SOLIDS IS IN EXCESS OF THE WEIGHT OF THE CERAMIC MATERIAL, CHARACTERIZED BY COMPLETE VITRIFICATION AND ABSENCE OF WATER ABSORPTIVENESS.
