Processes for immobilization of high-level solid wastes by glass and ceramic matrices
Description
Processes for immobilization of waste SiC hulls and fissile particles from reprocessing of HTGR fuels are presented. Compressed cylinders of waste-matrix material were formed under approx. 35, 71, or 142 MPa and sintered at approx. 500 to 10250C for approx. 1 hour. The cylinders containing 50% SiC-25% soft glass-25% red clay possess the most desirable properties (high mechanical strength, low surface area and low leachability) of several different compositions studies. Within the pressure range studied, the pressure of cylinder formation does not appear to have any significant effect on those properties. 5 tables
