Morley, J G; Boadle, C D

A reactor fuel element is described which comprises a vitrified glass- forming composition consisting of SiO/sub 2/ in a major proportion, a fissile material dispersed in the vitrified composition in a proportion of up to 10 wi %, and oxides of Al,Mg, Pb, Zr, Na, and/or K. The composition has a melting point below the temperature at which the fuel element is operated in the reactor so that the composition is in a plastic state in the reactor, Some of the advantages of the composition are simpler fuel element shape, operation at high temperatures, improved heat transfer to the casing, retention of fission products, corrosion and oxidation resistance, and damage self-healing.
