Abstract
1332888 Fuelling reactors COMMISSARIAT A L'ENERGIE ATOMIQUE 25 May 1972 [28 May 1971] 24708/72 Heading G6C A flask for handling a nuclear fuel assembly comprises an inner jacket 5 consisting of heatinsulating material 7, e.g. mineral wool or metallic elements operated by a layer of gas, enclosed between two metallic walls 9 and 11, the inner wall 11 conforming to the transverse cross-sectional profile of the fuel assembly 13, 15, 17 with provision for a necessary clearance space and the outer wall 9 being connected to a stainless steel cylindrical shell 3 by members 19 provided with openings. The external surface of the shell 3 is either surface treated, e.g. by polishing or coating, or provided with small machined corrugations (not shown) in order to enhance the transfer of heat by radiation into an argon atmosphere through which an irradiated fuel assembly is moved between withdrawal from the liquid metal of the primary vessel and immersion in a secondary-storage liquid metal. The fuel assembly has a bottom end-fitting 25 pierced with holes 27 through which liquid metal, e.g. sodium, flows into the lower and upper zones 13 and 17 made up of fertile elements and the central zone 15 containing fissile elements. When the flask is filled with sodium and the fuel assembly is introduced, the temperature rises locally within the zone 15 and the weight of the sodium within the jacket 5 becomes progressively lower than that of the surrounding annular column 21 of sodium. A thermosiphon effect is thus initiated and the sodium then circulates upwardly within the jacket 5 and downwardly within the annular column 21 as shown by the arrows.
