Abstract

1397014 Moulding nuclear fuel pellets AUSTRALIAN ATOMIC ENERGY COMMISSION 10 April 1973 [13 April 1972] 17277/73 Heading B5A [Also in Division G6] A nuclear fuel pellet is produced by extruding a mixture of powdered fuel and binder which is cut at the extruder die into pellets and, after drying, one or more juxtaposed pellets are compression moulded within a die of larger area, and at a pressure greater than that of extrusion, and the compression moulded pellet is sintered. Reject extruded pellets may be recycled to the extruder. The fuel may comprise natural or enriched UO 2 , or PuO 2 , or UO 2 -PuO 2 . The binder may compise camphor, when the sintering is effected in hydrogen or, with a less easily removable binder, debonding may be effected prior to sintering. The extrusion and compression moulded pellets may be of cylindrical solid, or tubular section, and the compression moulded pellet may comprise regions of different fissile content, as in the Fig. 4c embodiment wherein a compression moulded pellet is moulded from extruded pellets 18, 17 of solid and tubular section, between opposed plungers 19, 21.
