heavy water

light water

carbon dioxide

sodium

- Option 1: Heavy water

- Heavy water acts as both a moderator and a coolant in CANDU reactors.

- It slows down neutrons efficiently and can sustain chain reactions using natural uranium.

- Correct Answer

- Option 2: Light water

- Light water is commonly used in other reactors like PWRs and BWRs, but not in CANDU for both functions.

- Option 3: Carbon dioxide

- Carbon dioxide can be used as a coolant but is not used as a moderator in CANDU reactors.

- Option 4: Sodium

- Sodium is used as a coolant in fast breeder reactors but not in CANDU reactors.
