Abstract: The MATLAB (Matrix Laboratory) Simulink software is used as the simula tion software. Through theoretical research and investigation, the models for the main systems of PSFRP (Pool-type Sodium-cooled Fast Reactor Plant) are established, inclu-ding dynamic physics model of thc reactor, reactor thermal model, cold and hot pool models, distribution header model, intermediate heat exchanger model, pump model, pipe model and steam generator model. At the same time, it establishes the model of power regulation system using stepper motors as the driving motors. And closed loop are used to control step motor. Then, it constructs the structure model of PSFRP. With each of the disturbances including reactivity disturbance, primary and secondary flow turbulence and load disturbance, it simulates the“steam generator followed reactor" op-eration plan and obtains curve diagrams performed by the plan. It is concluded that, with reactivity disturbance, the PSFRP operates well. So, this operation plan could be used for PSFRP.
