The reactor consists of a tubed calandria vessel of austenitic stainless steel, which contains the heavy water moderator/reflector and 208 coolant tube assemblies. The moderator system consists of the calandria, coolers, pumps and purification system in the heavy water circuit, and control valves, dump valves and helium blowers in the helium circuit. The fuel is natural uranium in the form of sintered uranium dioxide pellets sheathed in thin zirconium alloy tubes to form solid fuel elements about 19.1 inches (48.53 cm) long by 0.6 inches (1.4 cm) diameter.
