Abstract

1,194,624. Processing spent nuclear fuel. EUROPEAN ATOMIC ENERGY COMMUNITY. 16 May, 1968 [19 May, 1967], No. 23425/68. Heading G6R. [Also in Division F3-F4] Irradiated nuclear fuel elements are melted down in the graphite crucible of an electrically heated tilting furnace (see Division F3-F4), the molten metal produced is degassed in a vacuum or an inert atmosphere, a precipitation inducing metal is added to the molten metal and mixed with it by tilting of the crucible, and then precipitated fissile material such as uranium, is allowed to settle out of the mixture whilst the crucible is kept stationary and maintained at a controlled temperature. The material in the crucible is finally allowed to cool to form an ingot in which the fissile material is concentrated at the bottom end, which may be sawn off for further processing after removal of the ingot from the crucible. Preferably the furnace is located in a shielded cell close to a storage pool for the fuel elements.
