The decay heat that is produced by nuclear reactor spent fuel must be cooled in a spent fuelstorage pool. A wickless heat pipe or a vertical two-phase closed thermosyphon (TPCT) isused to remove this decay heat. The objective of this research is to investigate the thermalperformance of a prototype model for a large-scale vertical TPCT as a passive coolingsystem for a nuclear research reactor spent fuel storage pool. An experimental investigationand numerical simulation using RELAP5/MOD 3.2 were used to investigate the TPCTthermal performance. The effects of the initial pressure, filling ratio, and heat load wereanalyzed. Demineralized water was used as the TPCT working fluid. The cooled water wascirculated in the water jacket as a cooling system. The experimental results show that thebest thermal performance was obtained at a thermal resistance of 0.22℃/W, the lowestinitial pressure, a filling ratio of 60%, and a high evaporator heat load. The simulationmodel that was experimentally validated showed a pattern and trend line similar to thoseof the experiment and can be used to predict the heat transfer phenomena of TPCT withvarying inputs.
