Contaminated graphite waste incineration

Conference:

Abstract

Dismantling of gas-cooled reactors commissioned 30 or 40 years ago generates a large quantity of graphite wastes. The best solution for waste processing seems to be incineration: graphite burns completely and secondary wastes ({sup 60}Co, {sup 137}Cs and {sup 55}Fe) represent 1 or 2 per cent of the initial volume, these contaminants are trapped in filters, carbon dioxide and tritium are rapidly dispersed into the atmosphere. An incinerator is designed for processing 1,000 tons/year of irradiated graphite. The validation program included 22 twelve hour tests and one 120-hours test to study combustion efficiency, solid wastes and gaseous wastes. Extrapolation to an industrial installation is examined and an impact assessment performed.
