An aluminum representation of a pressure vessel with fuel channels mounted on a wooden base. This memento was presented to J. Bayley by Ontario Hydro in appreciation of his efforts during the construction of Darlington Generating Station (G.S.). Julian Bayley started out his nuclear career at NPD and then moved on to Douglas Point, Pickering G.S., Bruce G.S. and finally to Darlington G.S. He retired to Deep River and then, to complete the circle, was contracted to work on the initial decommissioning of NPD. The mock-up stands approximately 7 cm by 7 cm and is mounted on a 22 cm square wooden base.
