Research on the Reactor and Turbine Matching Key Technology of CPR1000 Nuclear Power Plant for Industrial Steam Supply

The main steam extracted from the secondary side of nuclear power plant for steam supply in industry will affect the power matching between reactor and steam turbine, and the adaptability of reactor control system is the key of reactor-turbine matching research. By analyzing the influence of main steam extraction on reactor control system in CPR1000 nuclear power plant, a new reactor-turbine matching signal is designed and verified by modeling and maximum extraction steam flow rate is discussed. This study can provide important reference for the development of other nuclear energy comprehensive utilization.
