摘要

国际热核实验反应堆ITER（International Thermonuclear Experimental Reactor）计划是一个融合国际研究合作项目。中子屏蔽IWS位于VV内壳和外壳之间

用于屏蔽中子、降低环向磁场波纹度。利用ANSYS有限元软件对其中一个中子屏蔽模块进行了结构分析

并提出运用QR算法和ANSYS有限元软件相结合的方法去除二次应力

对去除二次应力的结果进行了评定

根据ASME标准

评定结果满足设计要求

为中子屏蔽模块的优化设计提供了参考依据。

Abstract

In the International Thermonuclear Experimental Reactor(ITER) project

in-wall shield(IWS) is used to fill the space between the inner and outer shells of the vacuum vessel

so as to provide neutron shield and reduce the toroidal field ripple.In this paper

structural strength analysis of one block of the neutron shield is carried out based on ANSYS

and the method for removing secondary stress is offered by combining QR algorithm and ANSYS.The result is evaluated

and it meets the design requirements.This provides reference for optimizing design of the neutron shield block.
