Description

technical field [0001] The invention belongs to the technical field of chemical reaction devices, and relates to a high-temperature sodium combustion reaction experimental device. Background technique [0002] Metal sodium is a coolant for sodium-cooled fast neutron reactors and has important applications in the field of nuclear power. There are many sodium-containing equipment in sodium-cooled fast reactors that have been operating at high temperature for a long time. These equipments (especially the sodium circuit pipelines and sodium valves, etc.) are covered with thermal insulation cotton to ensure the normal operation of the system. When a sodium leakage accident occurs in a sodium-cooled fast reactor, the thermal insulation cotton on the outer layer of the equipment pipeline may come into direct contact with the high-temperature sodium, and even cause the combustion reaction between the thermal insulation cotton and the high-temperature sodium. How to avoid such a comb...
