A full-scale replica of one of the target assemblies intended for isotope production using the Multipurpose Applied Physics Lattice (MAPLE) reactors at Chalk River. The actual targets, which would contain highly enriched uranium (HEU), consisted of a thin annulus of uranium dioxide cross-compressed between two concentric zircaloy tubes. The nominal dimensions are 15.2 mm OD, 13.2 mm ID and 482.6 mm length. The tubes have a number of dimples along their length to increase thermal heat transfer to the cooling water. The artifact is packaged in a 16 mm ID plastic tube.
