Abstract

1,043,543. Processing spent nuclear fuel. MINNESOTA MINING & MANUFACTURING CO. March 29, 1963, No. 12589/63. Heading G6R. Radio-active and fissionable products are recovered from a mixture of these materials with carbon, e.g. a graphite clad spent nuclear fuel element, by a process in which the carbon is oxidized by heating the mixture in an atmosphere consisting of an inert gas and less than 7% by volume of oxygen. The nuclear fuel, e.g. uranium, remains behind, together with the non-volatile fission products, as the oxide and the volatile fission product oxides pass on together with CO2 and are trapped downstream of the furnace. The preferred atmosphere contains at least 3% by volume of oxygen at no more than 5% and the preferred heating temperature is 1550-1650‹ F. The inert portion of the atmosphere is preferably from Group O of the Periodic Table having an atomic weight of less than 200, e.g. He. The uranium is extracted from the residual oxide by the established nitric acid-T.B.P. process. The exhaust gases from the furnace contain CO2, some CO, inert gas, e.g. He, some oxygen and the volatile fission products. A nickel catalyst converts Co to Co2, a cold trap removes the most volatile fission products, pyrogallol removes oxygen, a hot copper coil removes iodine, tellurium and ruthenium, and purified lime water removes Co2. A further cold trap removes Xe and Kr, leaving He for possible re-use.
