Abstract:
This paper takes verification of the reactor RRC system of a pressurized water reactor nuclear power plant as the research object. This paper determines the modelling scope of the RRC system according to the characteristics of the RRC system, modeled its process systems and control systems, and eventually constructed the digital Twins system of the RRC system, which realizes the dynamic closed-loop verification of the RRC system. The paper gives examples of implementation for typical accidents. The research results eventually achieve the purpose of accurate verification of the RRC system, and improve the safety and economy level of nuclear power plants, and play an important role in improving the safety and economy level of nuclear power plant operation.
