Abstract	Sodium fire is a design basis accident of sodium-cooled fast reactor. Sodium spray fire experiments were conducted in enclosed cell in this study to understand the sodium spray fire status and how to have an influence on the plant under realistic sodium spray. The process of spray fire experiment was described in the paper. Pressure transducers and thermocouples can be mounted on the room to record pressures and temperatures, respectively. Control and data acquisition system were designed to record most of data for the various instruments. Three experimental results showed realistic sodium spray combustion is mainly in the form of column fire burning. The rise of temperature is drastic on combustion zone. The highest temperature was observed during the sodium spray burning. The experimental results of pressure and temperature were compared to calculation values based on FEUMIX program. It was found the theoretical temperature on 10% sodium atomization of FEUMIX program is coincident with the experimental results of sodium fire burning at over 1500mm combustion zone at time 200 seconds. However, the experimental pressure curve has distinct from theoretical calculation value using FEUMIX program. The results can as a reference to analyze spray sodium fire combustion to help for nuclear safety analysis.
