摘要
在6种第四代国际先进堆堆型中,有4种是快堆能谱,而验证新堆型结构材料是否可用,必须在较高的快中子注量率下进行中子辐照,因此本文对在HFETR内布置高裂变密度辐照装置来提高局部孔道快中子注量率方法进行了研究。本文设计的辐照装置能够提高HFETR内大于0.1MeV中子注量率30%以上,达到7.28E14n/cm^2·s。
In the fourth generation of international advanced reactors, four reactor types are fast reactor spectrum reactor ,although there are six reactor types. And structural material is vertified available or not after irradiation by higher fast neutron spectrum,so this paper studys the method of raising local fast neutron flux by assigning high fission density device. Irradiation rig designed in this paper raises the neutron flux （〉0.1MeV） thirty percent,achieving 7.28E 14n/cm2·s.
