This engineering-design drawing, Number 551C877, was produced at the Civilian Atomic Power Division (CAPD) of Canadian General Electric plant in Peterborough, Ontario, as the design document for the 19-element fuel bundles that were used at the Nuclear Power Demonstration (NPD) reactor at Rolphton. The draftsman was G. Andrew and the design engineer was Les Haywood, who later played important roles in various generating station and heavy water projects within AECL. The original drawing was made in September 1959 and a total of twelve revisions are recorded, the last being on 28 June 1961.
