Detailed explanation-1: -Liquid sodium is used as a coolant in nuclear reactors to absorb the energy released from the reaction and transfer it to the water in steam generators to produce steam which is then used to turn the turbines to generate electricity.
Detailed explanation-2: -Liquid sodium is used as a coolant in fast breeder reactors on account of its excellent heat transfer properties. It must, however, be in the pure form to be compatible with structural materials.
Detailed explanation-3: -Sodium metal is used as a low-pressure coolant. It transfers heat extremely well and can keep a core cool without external power. It has been used extensively in both slow and fast neutron reactors (i.e. SGRs and SFRs).
Detailed explanation-4: -Heavy water, light water, sodium metal liquid is used as a coolant in the Atomic reactor.
