<p>1,202,074. Processing spent nuclear fuel. KERNFORSCHUNGSANLAGE JULICH G.m.b.H. 30 Nov., 1967 [12 Dec., 1966], No. 54536/67. Heading G6R. Nuclear fuel is recovered from fuel elements or fuel particles which are canned or coated with metal, graphite, or carbides by treating the elements or particles with a molten metal to dissolve the canning or coating and then separating the fuel from the molten bath. Commercial iron, pig iron, or steel serap may be used as the metallic material. If the fuel is in metal or carbide form, the bath is treated with an oxidizing agent, such as iron oxide, air, oxygen, Co 2 , or steam to produce a slag containing the fuel in oxide form. When a large amount of carbon has dissolved in the molten metal, it may be removed by combustion. Reference is made also to the use of tin as the metallic material.</p> |
