连续性钠处理工艺仿真模拟研究OA

Sodium-cooled fast reactors use a large amount of liquid sodium as a coolant.Due to its highly reactive chemical nature,it readily reacts with water,oxygen and other substances,leading to combustion or even explosion.Therefore,converting liquid sodium into stable substances is a crucial safety issue and technical challenge during the operation,maintenance and decommissioning of sodium-cooled fast reactors.This paper takes the continuous sodium-water reaction process as the research object,conducts steady-state simulation of the main process based on Aspen Plus and,through sensitivity analysis,obtains the influence of deionized water volume and reactor alkali liquid distribution ratio on various dynamic parameters of the system.The steady-state simulation results obtain parameters such as deionized water volume and reactor alkali liquid distribution ratio in the continuous sodium-water reaction process,which play a key guiding role in determining the key parameters of the continuous sodium-water reaction process;dynamic simulation determines the time and ability required for the system to correct disturbances under the disturbance of sodium feed rate.In summary,the feasibility,safety and stability of the continuous sodium-water reaction process are verified through simulation calculations,providing important basis and process input conditions for the construction,commissioning and operation of continuous sodium-water reaction test facilities.
