摘要 控制棒驱动机构(CRDM)是核电厂反应堆冷却剂系统压力边界的重要组成部分。其中钩爪作为CRDM的核心零件,在较长一段时间内因技术要求严苛、研发成本较高、制造困难等因素未能实现国产制造。试验基于我国华龙一号核电项目,通过对CRDM钩爪结构、原材料、焊接工艺的研究和改进,使用国产022Cr19Ni10N材料,并结合氧乙炔火焰焊的方法,在华龙一号堆型上成功研制出CRDM钩爪样件,为我国自主研发的三代核电站CRDM钩爪制造提供支撑。

Abstract: The control rod drive mechanism (referred to as “CRDM”) is an important component of the pressure boundary of the nuclear reactor power plant coolant system. As the core components of CRDM, latch arm has not been able to achieve domestic manufacturing due to strict technical requirements, high costs, and manufacturing difficulties. Based on China’s HPR1000 nuclear plant, this test studies and improves CRDM latch arm structure, materials and welding processes, the domestic 022Cr19Ni10N material is used, and the method of manual welding with oxyacetylene is combined. This experiment successfully realized the development of CRDM latch arm and provided support for the manufacture of CRDM latch arm of the three-generation nuclear power plant independently developed in China.
Key words:  control rod drive mechanism    latch arm    oxyacetylene flame welding
