A wooden-handled, beer mug made from a cut-off from tubing fabricated to make the pressure tubes used in the Nuclear Power Demonstration (NPD) reactor. The mug stands 15 cm tall and the outer diameter of the pressure-tube section is 9.0 cm. A 4 cm tall, “flying A” Atomic Energy of Canada Limited logo, is engraved on the surface. End cut-offs were retained after construction for quality control tests and were later used to generate retirement gifts etc. for AECL and Ontario Hydro employees who had worked on experiments at NPD.
