Keywords:sodium-cooled fast reactor, natural circulation decay heat removal conditions, porous body model, subchannel based CFD analysis method

We have developed the subchannel-based CFD analysis method for thermal hydraulics in a fuel subassembly. Energy mixing between adjacent subchannnels is implemented based on the porous body approach. The applicability of the method is investigated by comparing the results with measurements and subchannel analysis results.
