中国ITER固态实验包层模块第一壁结构初步分析

Preliminary structure analysis for the first-wall of CH HCSB TBM

对中国氦冷固态增殖剂实验包层模块(CH HCSB TBM)第一壁的重力分析结果表明,由重力导致的应力和位移形变很小,可以忽略其影响;而第一壁的热结构分析表明,第一壁铍保护板的应力偏大,从结构设计角度出发建议采用钨铜合金代替铍作为第一壁的保护材料。

Gravity analysis for the first-wall of CH HCSB TBM shows that the stress and displacement of first-wall caused by the gravity effect are too small and could be ignored. And the results of thermal-mechanical analysis for the first-wall show that the stress of Be armor is higher than allowable vaue, so it＇s proposed to choice W/Cu alloy replaced Be as the armor of first-wall under considering the point of structure design.
