秦山一期核电站是我国建造的首座商业PWR型核电站,其燃料棒和组件为我国自主设计和制造。为评价国产燃料元件在商业堆中的辐照性能,2014年该堆的8根乏燃料棒被运至中国原子能科学研究院303热室进行了辐照后检验。秦山燃料元件包壳为Zr-4合金,芯块为UO_2,富集度为3.4%,长度为3 200mm。在完成无损检验(NDE)和刺孔与裂变气体分析后,2014—2015年
Qinshan Phase I nuclear power station is the first commercial PWR nuclear power station constructed in China with its fuel rods and components designed and manufactured independently by China. In order to evaluate the irradiation performance of domestic fuel components in commercial reactors, eight spent fuel rods from the reactor were transported to the 303 Thermal Chamber of China Institute of Atomic Energy for post-irradiation inspection in 2014. Qinshan fuel cladding components for the Zr-4 alloy, UO_2 pellets, enrichment of 3.4%, a length of 3 200mm. After completing NDT and stabbing and fission gas analysis, 2014-2015
