Nuclear reactor power and axial power distribution reinforcement learning decoupling control method

Abstract

The invention discloses a nuclear reactor power and axial power distribution reinforcement learning decoupling control method. A reinforcement learning technology is utilized to eliminate a coupling effect between a reactor core coolant average temperature control subsystem and an axial power offset control subsystem in a pressurized water reactor mechanical compensation operation mode; two independent reinforcement learning feed-forward compensation modules are respectively used for compensating the rod speeds of the M rod group and the AO rod given by the reactor core coolant average temperature control subsystem and the axial power offset control subsystem, and the coupling effect of the M rod group and the AO rod in the process of adjusting the distribution of the reactor core power and the axial power is eliminated. According to the invention, decoupling control of reactor core power and axial power distribution in a pressurized water reactor mechanical compensation operation mode can be realized.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactor control, and in particular relates to a nuclear reactor power and axial power distribution reinforcement learning decoupling control method. Background technique [0002] The pressurized water reactor is the mainstream reactor type in the active nuclear power plants in the world today. The operating PWR basically adopts the traditional operation control mode (A mode or G mode) based on chemical compensation. During the load tracking process, the operator needs to adjust the core boron concentration frequently, and the reactivity adjustment speed is very slow. , the output of waste liquid is large, which affects the economy, safety and ecological benefits of the nuclear power plant; and, at the end of the service life, when the fuel consumption is high and the boron concentration is very low, the power improvement capability of the reactor is very weak, and the output of boron waste liquid ...

Problems solved by technology

Although this blocking design can largely alleviate the interference of the strong coupling effect of M rod group and AO rod adjustment on the stability of the control system, it also weakens the ability to control the axial power distribution of the core, and to a certain extent reduces the Reactor Safe Operating Margin
