Abstract
the development of the grind—leach process for the processing of beryllia—based fuels requires a knowledge of the dissolution of beryllia in nitric acid. A kinetic study using powdered specimens has proved suitable for the investigation of this system. The parameters studied include particle size, agitation, temperature, acid concentration, the effect of the addition of fluoride and aluminium, and the effect of neutron irradiation of the beryllia. The dissolution of beryllia in nitric acid is controlled by a chemical reaction at the surface of the solid and has an apparent activation energy of 18 kcal/mole.
