摘要:

ITER 低温泵需要定期再生循环以去除吸附的气体,处于安全考虑氢的累计体积摩尔浓度不能超过 1.5mol⋅m−3,从而使得再生的容积必须不小于15m3,需要额外设计容器结构以提供足够的再生容积,同时兼顾支撑和密封的作用。介绍了ITER 低温泵外部容器的结构与功能,并运用有限元分析方法对其不同载荷状况进行了数值计算,为其结构设计与优化提供了理论依据。

Abstract:

The cryo-pump for ITER vacuum vessel needs regeneration regularly to remove the gas, and the accumulated density of hydrogen cannot be higher than 1.5mol⋅m−3 due to the concern of nuclear safety and the overall volume for regeneration need at least 15m3. Therefore the cryo-pump needs extra volume provided by housing which also support and seal the cryo-pump. The structure and function of torus cryo-pump housing are introduced, and the associated finite element analysis and assessment justify the design feasibility.

Key words: Tokamak, Cryo-pump housing, Thermal load, Finite element
