1.	Select the desirable property of a moderator?(a) Moderator should absorb neutrons but slow down the neutrons as early as possible(b) It should have low thermal conductivity for better heat transfer(c) It shouldn’t be chemically unstable(d) It should have low resistance to corrosionThe question was posed to me in exam.The query is from Nuclear Reactor Components topic in division Nuclear Power Plant of Energy Engineering
Answer» Correct option is (c) It shouldn’t be chemically unstable Easiest explanation: It should be chemically stable and should not e decomposed DUE to NUCLEAR radiation. It should not absorb neutrons but SLOW down the neutrons as early as possible. It should have HIGH resistance to corrosion as it has to work under high pressure and TEMPERATURE.
