Breeder reactors employ liquid metal coolant because it

A Acts as good moderator
B Produces maximum steam
C Transfers heat from core at a fast rate
D Breeds neutrons

Correct Answer: Transfers heat from core at a fast rate

Breeder reactors employ liquid metal coolant because it transfers heat from core at a fast rate
It has a large specific heat so that it is an efficient heat-transfer fluid. In practice, those reactors which have used liquid metal coolants have been fast-neutron reactors.
