A 35 cm diameter, wooden (maple?) plaque with a cast-bronze maple leaf and a model of the Douglas Point CANDU reactor. The wooden plaque is made up of four glued quadrants. The origin of the design and the occasion for which it was produced is unknown. It existed at CRNL and had been long admired by Ken McDonald. As a result, it was put to use as a retirement gift for Ken. A small plaque reading “Ken McDonald, AECL 1971-1997” was added in 1997 for the presentation to Ken.
