CAP1400大型先进压水堆示范工程是我国在AP1000核电技术上进行再创新而建成的。在其设计中,对于国产主管道材料能否用RG1.207导则进行疲劳寿命曲线的修订是其设计的一个难题,也是我国第三代核电技术关键设备国产化急需解决的问题。本文针对该问题,开展了国产主管道材料——316LN钢在空气环境下的室温低周疲劳测试,获得了国产316LN钢不同应变范围(0.2%~
CAP1400 large advanced PWR demonstration project is China’s AP1000 nuclear power technology to create a new and built. In its design, the revision of the fatigue life curve of RG1.207 guideline for domestically produced main pipeline materials is a difficult problem in its design and also an urgent problem to be solved in the localization of the key equipment of China’s third generation nuclear power technology. In order to solve this problem, this paper carried out the room temperature low cycle fatigue test of 316LN steel, which is the main pipe material in China, and obtained the different strain range of domestic 316LN steel (0.2% ~
