Multi-Pod Heat Pipe(MPHP) is a new concept of assembly type of Two-Phase Closed Thermosyphon(TPCT) that was designed to be applied to the Passive Containment Cooling System(PCCS) of the nuclear power plant, using the characteristic of TPCT’s heat transfer according to the phase change of the working fluid. Main purpose of this study is to verify the function of the MPHP designed to remove decay heat that occurs in the containment, in the event of severe accidents, by crafting miniatures and through it, to verify the maximum heat value that the assembly type TPCT is able to cool down. The experiment was conducted in the ranges of 6~9kW, based on the theoretical results, and as a result, the maximum internal temperature increased by 2℃with each increase of 1kW, and the temperature of the steady state was maintained at the 112℃~114℃. Due to the fact that the heat transfer was more actively than expected, the internal pressure of the Boiling tank decreased before reaching the accident conditions, it was confirmed that more than 100% of the heat transfer took place rather than theoretically calculated expectation of 7kW of heat removal.
