Description

technical field [0001] The invention relates to the technical field of nuclear engineering corrosion tests, in particular to a corrosion test device and method for liquid lead or liquid lead-bismuth alloy. Background technique [0002] Liquid lead or liquid lead-bismuth alloys have high safety and reliability as reactor coolants, which can significantly improve the inherent safety of reactors compared with existing pressurized water reactor coolants, but liquid lead or liquid lead-bismuth alloys are harmful to structural materials. The corrosion problem is one of the key engineering problems to be solved in the design and development of this type of reactor. The research and development of new structural materials with good compatibility with liquid lead or liquid lead-bismuth alloy is a technical bottleneck that must be overcome in the development of lead-based reactors. The corrosion mechanism and laws in liquid lead-bismuth alloys are conducive to the research, screening...
