Recent calcination and vitrification process accomplishments
Experience gained through the development and operation of calciners and glass melting systems has provided the information needed for selection of a high-level waste solidification system. At the present time a spray calciner coupled to an in-can melter is sufficiently developed that design of an integrated system is underway for implementation at a U. S. commercial fuel reprocessing plant. A fluidized bed calciner operated with the addition of silica to produce a continuous inert bed (CIB) provides a second calciner which can also be used with the in-can melter. A joule-heated ceramic melter for converting calcine to glass shows great promise as a continuous one step process for converting liquid to glass. These systems will be demonstrated at the full scale capacities required for vitrifying HLLW from the reprocessing of 5 MT/day of spent power reactor fuel.
