Method and system for calculating reactivity of nuclear power plant

Abstract

The invention relates to a reactivity calculation method and system for a nuclear power plant, and the method comprises the steps: receiving a calculation type selected by a user, and displaying a corresponding parameter input control on a current interface according to the selected calculation type; receiving calculation parameter information input by a user according to the parameter input control; calculating the calculation parameter information according to a preset calculation rule to obtain corresponding reactive data information; and displaying the reactive data information on a current interface. By implementing the technical scheme of the invention, the workload of manual calculation is reduced, and the risk of human errors is reduced, so that the calculation efficiency is improved, operators can be liberated from heavy manual calculation, meanwhile, the reactivity calculation capability and speed of an operation value face to a transient state can be greatly improved, the control of a reactor is facilitated, and the reliability of the reactor is improved. The nuclear safety level of nuclear power plants is improved.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a reactivity calculation method and system for a nuclear power plant. Background technique [0002] Nuclear power plants mainly include reactors, steam generators, steam turbines, generators, power conditioning systems and other equipment. Among them, there will be continuous circulation of high-temperature and high-pressure water in the loop composed of nuclear reactors and steam generators. This process is called a nuclear power plant. loop. Usually, the high-temperature and high-pressure water in the primary circuit contains boron, which is transported by the reactor coolant pump, flows through the core of the reactor, absorbs the heat energy released by the fission of the core core, and then flows into the steam generator, where heat is transferred through the steam generator. The tube wall transfers heat energy to the feedwater of the steam generator in the secondary loop, whic...
