Heat transfer evaluation of natural convection outside the condenser in Passive Residual Heat Removal System of Molten Salt Reactor

A full scale water-cooled Passive Residual Heat Removal System was designed and built for a 2 MW Molten Salt Reactor. In the process of heating the water tank, the heat transfer characteristics of the condenser in the system had an important impact on the temperature distribution and the development...
