Static GK (CPO) Science & Technology

In the Canada Deuterium Uranium (CANDU) reactor, a natural uranium-fuelled reactor, the function of moderator and coolant is performed by:

heavy water

light water

carbon dioxide

sodium

- The CANDU reactor uses natural uranium as fuel. It’s unique in its approach to moderation and cooling.

- Option 1: Heavy water

- Acts as both the moderator and coolant in the CANDU reactor.

- Heavy water (D2O) is effective in slowing down neutrons without absorbing them much.

- Option 2: Light water

- Commonly used in other reactor types (like PWRs), but not in CANDU for moderation.

- Option 3: Carbon dioxide

- Used as coolant in some gas-cooled reactors, not as a moderator in CANDU.

- Option 4: Sodium

- A liquid metal coolant in fast reactors, not suitable for CANDU.
