摘　　要：随着在役核电厂的延寿需求和新建核电厂设计寿命的提高,对核反应堆结构材料的辐照中子注量提出了更高要求,导致材料在反应堆内的辐照时间急剧增加,研发周期增长,无法满足工程进度需求。本文结合中国高通量工程试验堆(HFETR)的特点,成功研制HFETR高注量率区的辐照装置,解决了在Φ63 mm辐照孔道中辐照装置温度控制难题,大幅度缩短材料的辐照试验周期。With the demand for life extension and the design life improvement for the in-service and new nuclear power plants, the neutron flux becomes higher during the irradiation of structural materials used in the nuclear reactors, leading to a sharp increase in material irradiation time. Correspondingly, the research period increases and cannot meet the project progress requirements. In the paper, an irradiation facility used in the high flux area of the High Flux Engineering Test Reactor （HFETR） was successfully developed according to the characteristics of the HFETR, and the problem of the material temperature control in the O63mm irradiation channel was also solved. The irradiation facility can greatly shorten the material irradiation test cycle and has been successfully applied in the engineering test.
