[0002] The existing test device for simulating the secondary side waste heat removal system of the steam generator includes a simulation of the secondary side passive waste heat removal system based on ACP1000, which can be used to test the operating characteristics of the secondary side passive waste heat removal system and reliability test verification, but it only models the passive waste heat removal system on the secondary side of the reactor. The primary side of the steam generator uses electric heating simulation, which cannot accurately simulate the water-to-water heat exchange process between the primary and secondary loops of the reactor. need

At the same time, the existing test device for simulating the waste heat discharge system on the secondary side of the steam generator is modeled according to the power volume method. Due to the defects of the modeling method, the modeled test device shows very poor local characteristics, which cannot meet the needs of scientific research.
