To provide a heat transport device of a fuel pool capable of stably cooling fuel pool water for a long time without the usage of external power.
The heat transport device 10 of the fuel pool 32 includes an ascending pipe 1 for receiving heat from the pool water 6 of the fuel pool 32 under the water surface, an upper communication pipe 3 arranged above the water surface of the fuel pool 32 and connected to an upper end of the ascending pipe 1, a lower communication pipe 4 connected to a lower end of the ascending pipe 1, a descending pipe 2 connected to the upper communication pipe 3 and the lower communication pipe 4, and a heat insulating part 5 covering an upper side of the ascending pipe 1 and a lower side of the descending pipe 2. The specific gravity of the heat insulating part 5 is smaller than the specific gravity of the pool water 6 so that the heat transport device 10 floats on the water surface of the fuel pool 32.
