Description

Technical field [0001] The invention relates to a liquid metal sodium thermo-hydraulic experiment loop system, which belongs to the field of engineering thermophysics and energy utilization. Background technique [0002] Nuclear energy has occupied an increasingly important position in today's world energy field. With the development of nuclear energy, how to make full use of limited uranium resources and effectively dispose of nuclear waste has attracted increasing attention. The sodium-cooled fast neutron reactor is an effective way to solve the above problems. Although sodium, as a coolant for sodium-cooled fast reactors, has good thermal conductivity and flow characteristics, its active chemical properties make it extremely difficult to study its thermal and hydraulic properties. For the design and construction of fast reactors and the safety analysis of fast reactor operation, the research on the thermal-hydraulic characteristics of liquid metal sodium is indispensable. Th...
