"Next generation nuclear power plants, specifically small modular reactor designs, are the best alternative to fossil fuels for power generation due to their power density and low carbon emissions and constant awareness of safety concerns. A promising safety feature of new designs is the removal of heat by passive systems in accident scenarios. The passive systems require no moving parts and no intervention by personnel. These systems must be accurately simulated for better understanding of the heat transport phenomena: natural convection cooling. Due to the fact that most work developing these passive heat removal systems are proprietary information, a passive heat removal system for a small modular reactor was designed and simulated in Star CCM+ to evaluate the capability of natural convective flows to remove decay heat in a shutdown scenario. The size and dimensions of the heat exchanger are based on the Westinghouse-SMR design. The design of the passive heat removal system was a hexagonal lattice heat exchanger. The final design was projected to dissipate the 56MW of decay heat at the rate simulated in Star CCM+"--Abstract, page iv.
