Natural circulation lead-cooled fast reactor heat exchangers operate under the harsh environment of high temperature, high pressure difference, high density and high corrosion, which can easily induce heat transfer tube rupture and blockage accidents, resulting in asymmetric thermal load or asymmetric resistance operation of the reactor. It has an important impact on the safe and stable operation of the reactor. This paper takes the lead-cooled dual-loop natural circulation system as the research object, and uses a non-dimensional analysis meth...
