Transformation of UREX effluents to solid oxides by concentration, denitration, and calcination.

[摘要] A literature survey was conducted on the potential means for converting two aqueous streams from the UREX process to solid oxides. The UREX process is similar to the PUREX solvent-extractions process and is designed to separate U, Tc, and I from the transuranics and other fission products contained in spent fuel. It was determined that converting these waste streams to oxides is technically feasible by a combination of evaporation, denitration, and calcination.
