ペース的に困難な問題があつた。 A conventional cooling method for a vacuum vessel for a nuclear fusion device is a cooling method using either water or gas. In the water cooling method, cooling after the baking operation is difficult when trying to directly pass water through a vacuum container at a high temperature of 200°C to 500°C due to water evaporation and thermal stress caused by local rapid cooling. Therefore, the temperature was first lowered by natural cooling to around 100℃,
After that, cooling is carried out by passing water through the vacuum container, but this method has the disadvantage that it takes an extremely long time to cool the vacuum container to the required temperature. On the other hand, with gas cooling method,
Cooling after the baking operation is performed using high-temperature gas (200℃ to 500℃) cooled in a vacuum container at a high temperature of 200℃ to 500℃.
°C) is discharged from the cooling pipe outlet, it is difficult to ensure electrical insulation of the cooling pipe with sufficient reliability. However, compared to the water cooling method described above, larger piping had to be used, creating a problem in terms of space.
