Solution
The correct option is C Liquid sodium
Liquid sodium is used as a coolant in nuclear reactors.
The high thermal conductivity properties effectively create a reservoir
of heat capacity which provides thermal inertia against overheating. Water is difficult
to use as a coolant for a fast reactor because water acts as a neutron
moderator that slows the fast neutrons into thermal neutrons.
The heat released by fission in nuclear reactors must be captured and
transferred for use in electricity generation. To this end, reactors use
coolants that remove heat from the core where the fuel is processed and carry
it to electrical generators. Coolants also serve to maintain manageable
pressures within the core.
