Preparation for storage of fission products

Patent number: 3994822


A method of preparing waste fission products for storage comprising combining graphite powder and a carbonaceous binder into one component, mixing this component with alpha-silicon carbide, and sprinkling this mixture on to waste fission product particles as the particles are tumbled in the presence of a solvent to form a tacky "overcoating" around the particles.The "overcoated" particles are warm pressed to form a "green" body, then the temperature is raised to carbonize the binder. The body is then heated at an elevated temperature in contact with silicon so as to melt the silicon and impregnate the body, to form a matrix of beta-silicon carbide enclosing the waste fission product particles by reaction-sintering.
