Description

technical field [0001] The invention belongs to the field of nuclear power, and in particular relates to a digital nuclear power plant primary circuit data acquisition system and a data processing method thereof. The present invention can perform offline data collection and data processing as required, and can also be used as a part of the DCS system to perform online data collection and data processing, and display the analysis results on the DCS screen in real time through data communication. Background technique [0002] The reactor core of the digital nuclear power plant produces huge heat energy due to nuclear fuel fission. The water pumped into the core by the main pump is heated into high-temperature and high-pressure water. The high-temperature and high-pressure water flows through the heat transfer U-shaped tube in the steam generator, and the The heat energy is transferred to the secondary circuit cooling water outside the U-shaped tube, and after the heat is relea...
