Abstract
1,030,466. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 10, 1965 [Feb. 18, 1964], No. 5814/65. Heading G6C. The fuel pencils of a cluster-type fuel element are supported between their ends (Fig. 1, not shown) by a cross-piece 2 within an outer jacket 1, of graphite, for instance, the crosspiece 2 being secured to the jacket 1 by a number of studs 7 retained by a collar 11 within apertures 8, evenly distributed around the jacket periphery, so as to bear against the cross-piece 2. Preferably, the material used for the collar 11 is the same as that used for the cross-piece 2 and the studs 7 so that these components have the same coefficient of thermal expansion. In one embodiment, the studs 7 each have an individual spring strip in contact with the cross-piece 2 to damp vibrations of the pencils caused by the flow of coolant in the jacket 1 when the fuel element is in use.
