Abstract

Synroc is a titanate-based ceramic developed for immobilization of high-level nuclear reactor wastes in solid form. Fluid bed Synroc production permits slurry drying, calcining and redox to be carried out in a single unit. We present results of studies from two fluid beds; the Idaho Exxon internally-heated unit and the externally-heated unit constructed at Lawrence Livermore National Laboratory (LLNL). Bed operation over a range of temperature, feed rate, fluidizing rate and redox conditions indicate that high density, uniform particle-size Synroc powders are produced which facilitate the densification step and give HUP parts with dense, well-developed phases and good leaching characteristics.
