A 17.5 cm high by 14.5 wide photoetch diagram starting at the top with ZEEP (1945) and progressing in a clockwise manner with illustrations of the next fifteen members of the CANDU family that came in operation during the long (1949-1986) career of J.H. (Harry) Collins. The unit was presented to Collins, who served in the “reactors” area of CRNL in numerous important roles, on his retirement. The aluminum photoetch diagram is bonded to a steel backing bent to form a stand-up unit. Two standard ~2 cm AECL “Flying A” lapel pins, bonded to magnets, can be located at any desired locations on the unit.
