摘　　要：科学合理的管道设计选材能够保证大型商用快堆的长期安全运行,同时降低建设成本。本文以大型商用快堆二回路主冷却系统主管道为研究对象,将燃煤电站常用P22、P91和P92管道材料与奥氏体不锈钢316进行对比分析,提出应优选P91作为大型商用快堆管道材料,同时应开展大口径薄壁管的工艺开发和材料验证工作,从而实现设计水平与制造水平的完美结合。Scientific and rational piping material selection can ensure the long-term safe operation of large commercial fast reactor and reduce the construction cost. In this paper, the main pipe of the secondary main cooling system of large commercial fast reactor is taken as the research object, and the piping materials of P22, P91 and P92 commonly used in coal-fired power plant are compared with austenitic stainless steel 316. It is proposed that P91 should be selected as the piping materials of large commercial fast reactor, and at the same time the manufacturing development and material verification of large diameter thin-walled piping material should be carried out. Thus it can be realized the perfect combination of design level and manufacturing level.
