| 内容記述 | The JT-60SA Tokamak is provided with a cryogenic system with a refrigeration capacity of 9 kW (eqv.) at 4.5 K. Before commissioning and during occasional warm-up periods the total 3.6 t helium inventory (at ∼1.5 Mpa(g)) is stored in six pressure vessels. Each vessel is 22 m long, has a diameter of 4 m, 250 m3 volume, and weighs about 73 t. As the vessels will store pure helium, the tightness and cleanliness require- ments were quite demanding. One of the vessels is also used to receive the cold helium (20 K) from the cryogenic system quench line, following a fast discharge of the superconducting coils. A special 18 m long helium diffuser system and a thermal barrier connector at the quench line flange have been designed and manufactured to avoid local chilling of the vessel wall below the minimum allowed temperature of the material. | |||||
