在核电站安装过程中,与放射性介质接触的管道安装焊接所采用的是核级不锈钢管道焊接,对其化学成分和力学性能有着严格的要求。由于在国内还没有核级不锈钢焊接材料的制造商,本文就核电站安装过程中使用进口核级不锈钢管道焊接材料的经验,对核级焊接材料国产化的技术要求进行探讨,明确满足核级不锈钢管道焊接材料技术要求的具体技术措施。 In the nuclear power station installation process, the radioactive medium in contact with the pipeline installation and welding is used in nuclear grade stainless steel pipe welding, its chemical composition and mechanical properties have strict requirements. Since there is no nuclear-grade stainless steel welding material manufacturer in China, this paper discusses the technical requirements for the localization of nuclear-level welding materials on the experience of using imported nuclear grade stainless steel pipe welding materials in the process of nuclear power station installation, and clearly meets the requirements of nuclear grade stainless steel pipes Technical requirements for welding materials and specific technical measures.
