Abstract

857,422. Nuclear fuel elements. GENERAL ELECTRIC CO. Ltd. Nov. 25, 1958 [Nov. 25, 1957], No. 36737/57. Class 39(4). A rod type fuel element 1 enclosed in a can 2 having fins 14, Fig. 1, is supported in a graphite sleeve 5 by a beam 6, the assembly being removable as a unit from a channel within the reactor core. The beam 6 is preferably of a sintered alumina based ceramic material, but alternatively may be of graphite or metal, and has an opening 11 receiving a spigot 3 on the fuel element end cap 15, a circular channel 12 in the beam receiving an extension of the can and end cap. The beam 6 is introduced into the sleeve 5 in the chain-line position 9 and is then orientated to lie on the lower edges of slots 7, 8, the longer slot 7 permitting this turning movement, the spigot 3 then being introduced into the opening 11 and retained by a disc 13. In a modified arrangement, Figs. 4, 6, the can 2 has straight longitudinal fins 16 and four helical fins 17 closely approaching the inner wall of the sleeve 5. The fuel element 1 is supported by the beam 6 but is centralised within the sleeve by spiders 19, 21 secured to the upper and lower ends of the can, the ends of the fins 17 being attached to the spider arms. Specification 791,011 is referred to.
