2. What is Pressurized Heavy Water Reactor What is CANDU ? CANada Deuterium Uranium - the name gives the design started as the Canadian contribution to the War effort: to produce plutonium using natural uranium and heavy water the first reactor to go critical outside the U.S. was ZEEP in 1945

17. Pressurized Heavy Water Reactor CANDU Auxiliary Systems CANDU has systems not found in other types automated refuelling & fuel handling system annulus gas system (leak-before-break) shield cooling system heavy water vapour and liquid recovery and systems that are found in other types primary pressure & inventory control shutdown cooling system shutdown systems, Emergency Core Cooling, containment, emergency power etc.
18. Pressurized Heavy Water Reactor CANDU Systems CANDU Does Not Need Some systems are not needed in CANDU or are much simpler no boron control system in the coolant no boron addition to ECC water no criticality concerns outside the reactor for new or used fuel simpler core, reactivity devices
