Description

technical field [0001] The invention belongs to the technical field of nuclear power system simulation and control methods, and particularly relates to a method for building a steam generator digital twin and data-driven integrated system. Background technique [0002] The steam generator is the key equipment connecting the primary and secondary circuits in the nuclear power system of the pressurized water reactor, and it undertakes the important functions of the heat transfer boundary and the pressure boundary. However, due to the intense two-phase flow boiling heat transfer phenomenon inside the steam generator, accompanied by complex chemical processes such as corrosion deposition and radioactive migration, the steam generator accident accounts for an important part of the PWR nuclear power plant accident. This poses a great threat to the safety and economy of the PWR nuclear power plant system. The real-time monitoring and control of the steam generator operating status...
