Abstract
1,245,597. Processing spent nuclear fuel. KERNFORSCHUNGSANLAGE JULICH G.m.b.H. 20 Sept., 1968 [23 Sept., 1967], No. 44891/68. Heading G6R. Fuel elements comprising fuel particles coated with pyrolytic graphite and contained in a graphite envelope or embedded in a graphite matrix are disentegrated to separate the coated particles from the graphite of the envelope or matrix by reacting the fuel elements with ferric chloride at a temperature in the region 290- 350‹ C. The pyrolytic graphite is not affected. An apparatus for carrying out the method comprises, Fig. 2, a reaction container, having chambers 1, 2, rotatable about its horizontal axis by a motor 8 and heated by coils 3, 4, 5. The chamber 1 is charged through a sealable aperture 6 with the fuel elements and with the ferric chloride and the entire container is heated to 290-350‹ C. by the coils 3, 4, 5 so that the graphite disintegrates. Chamber 2 is now cooled but chamber 1 is brought to 400‹ C. by the coils 3, 4 so that the ferric chloride evaporates and passes through aperture 2b in partition 2a into chamber 2 where it condenses for re-use, the conical plug 9 being withdrawn from the position shown to open the aperture. The contents of chamber 1 are removed through the aperture 6 by tilting the platform 11, the plug 9 then obstructing the aperture 2b to retain the ferric chloride in chamber 2.
