A transport container for nuclear fuel is provided with an outer container having internal insulation, the insulation defining an internal cavity. The cavity receives a plurality of fuel containers wherein the internal volume of the fuel containers is at least 5% of the external volume of the outer container. The container allows substantially higher volume proportions of enriched fuel to be safely transported than is possible with prior containers.

Container for nuclear fuel transportation

A casing for the protection of an article contained within the casing is described, the protective casing comprising: at least two casing members which are assemblable to constitute a casing having an internal volume to receive the article, each of said at least two casing members comprising: an outer skin of fiber reinforced plastics material having a plurality of layers of reinforcing fibers in a plastics material matrix; an inner skin of fiber reinforced plastics material having a plurality of layers of reinforcing fibers in a plastics material matrix; a filling of a low density core material in a space between the outer and inner skin members; sealing means disposed in the joint face between said at least two casing members; and fastener means to hold said at least two members together.

Protective casing

A spacer grid for fuel assemblies in a water reactor is provided. The grid shell is shaped so that a pressing in Zircaloy can be made. Cross members in a lattice in the shell provide spacing for the fuel pins of the fuel assembly. Each fuel pin has its own cell in the lattice, and at least some of the joints between the members comprise two attachment points spaced along one of the members at a single intersection.
