In-vessel large-scale thermohydraulic analyses for a sodium-cooled fast breeder reactor generating 1500 MWe were carried out using a computer code system for multi-scale and multi physics simulations to realize optimum upper plenum geometry against free surface behavior The system consisted of three thermohydraulics computer programs and three thermomechanical computer programs to simulate fluid-structure thermal interaction phenomena in various applications. Furthermore, a response surface methodology was applied to find efficiently the optimum upper plenum geometry. From the large-scale analyses with approximately 1,800,000 computational meshes, it was concluded that the maximum swelling and the maximum horizontal flow velocity at the free surface in an optimal case were decreased largely by 1/3 and one-half, respectively.
