| 摘 要： | 为分析快中子辐照和高温等条件下石墨砖在整修寿期内的力学行为，采用改编的ＡＤＩＮＡ和ＡＤＩＮＡＴ程序，计算了１０ＭＷ高温气冷实验堆石墨砖受快中子辐照后所产生的变形和应力历史。计算结果表明，改编后的ＡＤＩＮＡ和ＡＤＩＮＡＴ程序考虑了温度和辐照条件下多个参数的变化，可以用来分析石墨砖在辐照条件下的应力和变形。

| Abstract: | In order to analyze the mechanical behavior history of graphite blocks under the fast neutron irradiation and high temperature during their lifetimes,an appropriate and feasible modification to ADINA and ADINAT codes has been carried out.In terms of modified codes,the deformation and stress history of a graphite block,under the fast neutron irra diation and high temperature,in the sider reflector of 10MW HTGR is given out.It is shown that the modified codes whick taking into account variations of many physical pa rameters of graphite material under irradiation and high temperature can be used to analyze the irradiation deformation and strss of graphite blocks. |
