Abstract

1,139,967. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 21 Nov., 1967 [5 Dec., 1966], No. 53003/67. Heading G6C. A fuel element assembly comprises a bundle of pins 10 mounted between end fittings 14, 16 within a hexagonal - section casing 12 through which the reactor coolant flows. The casing 12 is formed from a thin metallic strip wrapped in a helix around the pins 10 so as to be in contact therewith, adjacent turns of the helix being brazed or welded along joints 26 and the ends of the casing being similarly secured to the fittings 14, 16. In a modification (Fig. 2, not shown) the turns of the helix overlap and are secured by riveting.
