The simulation of pressurized water reactor NPP physical process

The simulations of pressurized water reactor (PWR) nuclear power plant (NPP) is a very important domain in the society of nuclear power, and there are several problems with the current PWR-NPP simulations. First, the current physical modeling of PWR is over-simplified which can bring convenience of implementation, while severe inaccuracy is prone to be incurred at some critical situation. Second, with the development of technology, some devices are introduced into the PWR, which are not taken into consideration in the current model. To solve these problems, this paper deduced the transfer functions that can properly describe the physical process of PWP-NPP, and a Matlab implementation was given. The experiments basically demonstrated the operation of PWR-NPP and gave promising results.
