示范快堆电站钠管路系统的主要特点是高温、薄壁和大口径,同时在液态金属钠环境中长期运行。区别于压水堆高压厚壁的管路特点,如何保证钠管路系统的高温可靠性是快堆钠管道设计需考虑的首要问题。示范快堆电站主管道材料研制目的是获得主管道材料在高温钠工况下的各项理化指
The main features of the sodium pipeline system of the demonstration fast reactors are high temperature, thin-walled and large diameter, while long-term operation in the liquid sodium metal environment. Differing from the characteristics of high pressure and high pressure PWR pipelines, how to ensure the high temperature reliability of sodium pipeline system is the most important issue to be considered in the design of SFDA sodium pipeline. Demonstration fast reactor power plant main pipeline material development objective is to obtain the main pipeline material in high temperature sodium conditions of the various physical and chemical finger
