Use of molten metal as a coolant in fast breeder reactor helps in_________________?
Correct answer: B. Rapid heat transfer from the core
- A. Accelerating the reaction rate in the core
- B. Rapid heat transfer from the core
- C. Breeding neutrons
- D. Accelerating the neutrons
Explanation
Molten metals such as sodium have high thermal conductivity and can remove heat rapidly from the reactor core. They do not themselves accelerate the reaction or breed neutrons.
