Keywords:SFP, LOCA, CFD, Natural Convection, Fuel Loading Pattern, Fuel Temperature, Porous Body Approximation, STAR-CCM+

About the condition of loss of coolant in the SFP, the macroscopic flow condition and the temparature distribution in the reactor building are evaluated through the CFD analysis overall the oparating floor at the reactor building. Also, the spent fuels aproximating the porous body are loading into SFP, the fuel temparature distribution depend on the fuel loading pattern are evaluated.
