Claim 1
Independent Claim
98 words
THE METHOD OF PRODUCING A URANIUM DIOXIDE-PLUTONIUM DIOXIDE CERAMIC FUEL MATERIAL FOR NUCLEAR-REACTORS WHICH COMPRISES DISSOLVING A PLUTONIUM SALT IN AN ORGANIC SOLVENT FOR SUCH PLUTONIUM SALT, ADDING AN ORGANIC BINDING AGENT FOR URANIUM DIOXIDE TO SAID SOLUTION, COMBINING THE SOLUTION CONTAINING THE BINDING AGENT WITH POWDERED URANIUM DIOXIDE, DRYING THE RESULTING MIXTURE TO REMOVE THE SOLVENT AND PRODUCE A FREE FLOWING POWDER, COMPACTING THE POWDER, AND HEATING THE COMPOUND POWDER AT AN ELEVATED TEMPERATURE AND FOR A PERIOD OF TIME SUFFICIENT TO EFFECT A SINTERING THEREOF AND PRODUCE AN INTIMATE MIXTURE OF URANIUM DIOXIDE AND PLUTONIUM DIOXIDE.
