Candu reactor is a ______________ nuclear reactor?
Correct answer: D. Natural uranium fuelled heavy water cooled & moderated
- A. Fast breeder
- B. Highly enriched uranium (85% U-235) fuelled
- C. Homogeneous
- D. Natural uranium fuelled heavy water cooled & moderated
Explanation
A CANDU reactor uses natural uranium fuel and heavy water as both moderator and coolant. Heavy water permits a chain reaction with natural uranium, unlike the enriched-fuel requirement of many light-water reactors.
