  2.    Density ; hence core volume for a given power output would be smaller
  3.    Resistance to effects of irradiation
  4.    All of the above
Explanation:-
Answer: Option D. -> All of the above
Question 9. Heavy water (D₂O) in a nuclear reactor serves as a

  2.    Moderator
  3.    Both A & B
  4.    Neutron absorber
Explanation:-
Answer: Option C. -> Both A & B
Question 10. Moderating material used in a thermal-reactor should be a
  1.    Good absorber of neutrons
  2.    Solid substance
  3.    Poor absorber of neutrons
  4.    None of these
Explanation:-
Answer: Option C. -> Poor absorber of neutrons
