Characterization and Performance of Fluidized Bed Steam Reforming (FBSR) Product as a Final Waste Form

A demonstration of Fluidized Bed Steam Reforming (FBSR) was recently completed on a Hanford Low Activity Waste (LAW) simulant. This technology produced stable mineral phases (feldspathoids) when co-fired with clay. The mineral phases are cage structured and were determined to retain anions as well as cations such as Re (simulant for Tc) in the mineral cages. The FBSR mineral waste form exhibited incongruent leaching characteristics during Product Consistency Testing (PCT or ASTM C1285). FBSR mineral waste forms are EPA regulatory compliant at the Universal Treatment Standard (UTS) making delisting an attractive option for this waste form
