Abstract (en)
The container consists of a thick inner wall (3), e.g. of steel, a hydrogenated resin neutron shielding layer, and an outer wall (5) with grooves (7) to enhance air cooling. The grooves are separated by relief portions (6), are 1-30 mm wide and 1-15 mm deep, and are spaced no more than 50 mm apart. The outer wall of the container can be of steel, cast iron, aluminium, copper or alloys of these, and grooves in its surface can lie perpendicular or parallel to its generating line, or they can run in one or more spiral lines. They can be made by moulding, extruding or machining.
