启动中子源棒,是为我国第一座核电厂——秦山核电厂反应堆启动而研制的。源棒由双层不锈钢壳焊接密封的~(210)Po-Be中子源、氧化铝隔热片、弹簧和不锈钢外包壳管等部件组装而成。中子源的安全性能是中子源棒质量的重要指标。设计部门规定密封中子源的安全质量分级等级达到GB/E65545。按照GB4075的规定,对该源进行了包括温度、外压、冲击、振动和穿刺等项目的
Start neutron source rod, is for China’s first nuclear power plant - Qinshan nuclear power plant reactor startup and development. The source rod is assembled from a ~ (210) Po-Be neutron source welded by a double stainless steel shell, a thermal insulator made of alumina, a spring and a stainless steel cladding tube. The safety of neutron sources is an important indicator of the quality of neutron source rods. Design department provides sealed neutron source of safety and quality rating to GB / E65545. In accordance with the provisions of GB4075, the source was carried out, including the temperature, external pressure, shock, vibration and puncture and other projects
