- W36572242 abstract "Simulated High Level Radioactive Waste has been incorporated in sintered SYNROC-B Ceramic matrices prepared by subsolidus sintering techniques. Phase and compositional analyses have been carried out by x-ray diffraction techniques and scanning electron microscope equipped with energy dispersive analysis of x-ray (SEM/EDAX) analyses on fracture surfaces. Modified SNYROC-B compositions have been formulated based on computer-calculated ion substitutions relative to the stoichiometries of the major phases, (Hollandite (H), Perovskite (P), Zirconolite (Z)) and their respective abilities to retain HLW ions in their lattice structures, either substitutionally or interstitially. When prepared and sintered, the Modified SYNROC-B compositions yield clean H,P,Z assemblages, free of minor phases which might be questionable with respect to compatibility with major phases and HLW ions, and/or chemical and/or radiation stability under long-term disposal conditions. Chemical stability of the Modified SYNROC-B loaded with 10 and 15 wt% simulated HLW has been studied by leaching in pure distilled water at approx. 100/sup 0/C and in simulated brines similar to those found in geologic disposal sites at their boiling temperatures (approx. 110/sup 0/C) at atmospheric pressure. High pressure, high temperature leaching in simulated brine has also been investigated at approx. 50 atm and 270/sup 0/C for the Modified SYNROC-B Ceramic wastemore » form loaded with 15 wt% simulated PW-4b radwaste. In all instances, the observed leach rates have been near or below (mostly below) present analytical detection limits (AAS or NAA).« less" @default.
