In which of the Following reactor is heavy hydrogen isotope H-2 is use

1.	In which of the Following reactor is heavy hydrogen isotope H-2 is used as moderator?(a) Boiling water reactor(b) Pressurized water reactor(c) Candu reactor(d) Thermal reactorThis question was posed to me by my college professor while I was bunking the class.The origin of the question is Types of Nuclear Reactor & Nuclear Waste in chapter Nuclear Power Plant of Energy Engineering
Answer» Correct answer is (c) Candu reactor To ELABORATE: Heavy WATER composed of heavy hydrogen isotope H-2 is USED as a moderator and coolant in some POWER and research reactors. These reactors use heavy water as a moderator and primary coolant and light water as SECONDARY coolant.
