【 摘 要 】

The fluidized bed steam reforming (FBSR) technology should be further evaluated as a final waste form for Hanford LAW wastes. This technology produces stable mineralized phases which are more durable than a high sodium vitrified waste form. The mineral phases are the same as many of the phases produced in higher temperature waste forms such as supercalcine, glass-bonded ceramics, and SYNthetic ROCk (SYNROC) yet the phases are produced at moderate steam reformer operating temperatures. The mineral phases bind the radionuclide and hazardous species in cage structured mineral phases. The radionuclides and hazardous species are ionically bonded to silica and alumina tetrahedra in the structure as well as to Na ions.
