Question

Some statements about heavy water are given below. Which of the following statements are true?

• A. Heavy water is used as moderator in nuclear reactors
• B. Heavy water is more associated than ordinary water
• C. Heavy water is more effective solvent than ordinary water
• D. All of the above

Hint:

Heavy water is often used in reactors because it can slow down neutrons without absorbing them.

Answer 1

The Correct Option is A

Heavy water, \( D_2O \), is used as a neutron moderator in nuclear reactors. It has a higher neutron absorption cross-section than regular water, making it more effective for slowing down neutrons. However, it is less common for other uses compared to ordinary water.

Step 2: Conclusion.
The correct statement is that heavy water is used as a moderator in nuclear reactors, corresponding to option (a).
