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] Sodium metal is the coolant of sodium-cooled fast neutron reactors and has important applications in the field of nuclear power. There are many sodium-containing equipment in the sodium-cooled fast reactor operating at high temperature for a long time. These equipment (especially sodium loop pipes 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 insulation cotton on the outer layer of the equipment pipeline may directly contact with the high-temperature sodium, and even cause a combustion reaction between the insulation cotton and the high-temperature sodium. How to avoid such a combustion reaction is crucial to ensure the normal o...
