 Intermediate heat exchanger (IHX) in a pool-type liquid metal cooled fast breeder reactor is an important heat exchanging component as it transfer heat from the radioactive primary sodium in the pool to the non-radioactive secondary sodium. The secondary sodium ultimately heats up water in a steam Generator (SG) to produce the steam for power generation. Intermediate heat exchanger is a sodium to sodium heat exchanger and is modeled using COMSOL multiphysics code. The code estimates the temperature and velocity distribution of primary sodium in the shell side.
