Abstract

A spherical graphite matrix element fueled with uranium dicarbide and clad with an impermeable layer of silicon carbide is described for use in pebble bed gas-cooled reactors. The following topics are discussed: fabrication techniques, cladding permeability tests, oxidation resistance, carbon density, crushing strength, impact resistance, fuel distribution, self-welding characteristics, and resistance to thermal cycling.
