Abstract

1,096,304. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Aug. 6, 1965 [Aug. 28, 1964], No. 35444/64. Heading G6C. A fuel element (Fig. 1, not shown) comprises an outer tubular casing (1) surrounding a plurality of spaced concentric fuel-containing tubes (3) supported lengthwise between cantilever members (2) secured to the inner surface of the casing (1). Each member (2) (Fig. 2, not shown) has extension portions (4) which extend between the fuel tubes (3) to ensure correct spacing. The fuel tubes (3) which each comprise a core of highly enriched uraniumaluminium alloy clad in aluminium are secured to the members (2) by rivets (5) which extend through apertures (6, 7) in the fuel tubes (3) and extension portions (4), respectively. The members (2) are welded to the casing (1). A portion of the casing (1) extending above the fuel tubes (3) is apertured to form a coolant discharge section, as is more fully described in Specification 1,096,303. Coolant after passing upwards through the annular passages between the fuel tubes (3) enters a frusto-conical shaped diffuser (12) provided with holes (13) through which the coolant passes radially outwards and then through holes (11) in the casing (1) to issue into the surrounding moderator as a non- turbulent flow. A flange (10) at the top of the easing (1) is provided with a plurality of apertures (14) which may be used as emergency coolant passages if necessary, for example, if the normal coolant flow is interrupted coolant can be fed into the element from above via the apertures (14).
