ABSTRACT:
Fuel, fertile material or absorber material containing particles for high temperature fuel elements are coated in a fluidized bed by heating the particles and fluidizing through carrier gas preheated to the desired temperature. The coating gas, having a higher velocity than the carrier gas causing fluidizing, is blown into the fluidized particle bed from one or more nozzles from above counter to the flow of the carrier gas. The nozzles end above the fluidized layer.
