Laboratory development of the grind-leach process for the H.T.G.C.R. fuel cycle, Part III - comminution of beryllia matrix fuels.

Abstract

A comminution process has been studied for the preparation of fuel from an H.T.G.C.R. pebble bed reactor for leaching prior to purification and recycle of its valuable constituents the selection of suitable equipment for this step is discussed, and experimental work to demonstrate a three-stage vibratory grinding circuit on a small scale, using inactive fuel, is described it has been shown that, for inactive fuel, a ground product having characteristics which make it suitable for feed material to the selective leaching step can be produced by this technique.
