为避免真空室屏蔽层受地震的影响，根据ITER中子屏蔽层结构对其中子屏蔽单元模块进行了单点响应谱分析，将中子屏蔽结构的模态分析结果与法国某地的加速度谱进行了模态叠加。分析发现，应力极值在许可应力范围之内。

Single-point response spectrum analysis of neutron shielding module was done to check out structural design scheme under earthquake load.Modal analysis of neutrion shielding module of ITER vacuum vessel was built.By modal superposition with acceleration spectrum of ITER final loca-tion in France,security against earthquake load of this structure was analyzed.The results show the validity of this structural design of this neuton shielding of vacuum vessel.
