Abstract

The invention belongs to the field of reactor control and protection systems and provides a method, a system and terminal equipment for establishing and verifying a nuclear power theoretical model. The method comprises the following steps: obtaining theoretical current and theoretical power of RPN through a pre-established nuclear power theoretical model, and obtaining actually measured current and actually measured power; obtaining the changing trend of the theoretical current along with fuel consumption according to the theoretical current, obtaining the changing trend of the actually measured current along with fuel consumption according to the actually measured current, and verifying the validity of the nuclear power theoretical model according to the uniformity of the changing trend of the theoretical current along with fuel consumption and the changing trend of the actually measured current along with fuel consumption; verifying whether the actually measured power meets the expectation or not according to the conforming condition of the theoretical power and the actually measured power; and accurately estimating the nuclear power of the RPN according to the nuclear power theoretical model which is verified to be correct, so that corresponding solutions can be formulated in advance before a nuclear power unit is in the middle and late life cycle so as to avoid the problemsof high indication and large fluctuation of the nuclear power of the RPN and solve the problem of limited unit output.
