Pressurized water reactor core control method and device, computer equipment and storage medium

Abstract

The invention relates to a pressurized water reactor core control method and device, computer equipment and a storage medium. The method comprises the following steps: determining an operation mode of a pressurized water reactor core, wherein the pressurized water reactor core is loaded with at least one first control rod group, a second control rod group, a third control rod group and a plurality of fuel assemblies; obtaining a rod group control instruction corresponding to the operation mode; and controlling the pressurized water reactor core based on the first control rod group, the second control rod group and the third control rod group according to the rod group control instruction. By adopting the method, the aim of automatically controlling the pressurized water reactor core through the first control rod group, the second control rod group and the third control rod group is fulfilled, and the pressurized water reactor core does not need to be controlled by frequently adjusting the boron concentration in the primary loop coolant, so that the control flow of the pressurized water reactor core is simplified, and the control efficiency of the pressurized water reactor core is further improved.

Description

technical field [0001] The present application relates to the technical field of control, in particular to a control method, device, computer equipment and storage medium for a pressurized water reactor core. Background technique [0002] The PWR core is an important part of the PWR, and the PWR can be controlled by controlling the power of the PWR core. [0003] At present, the control method for the power of the pressurized water reactor core is generally to change the reactivity of the core by adjusting the boron concentration in the coolant of the primary circuit; however, this control method needs to inject Water or high-concentration boron solution is used to dilute or borate the coolant; since it takes a certain amount of time for the coolant in the primary circuit to mix evenly after each dilution or boronization, the boron concentration of the primary coolant changes slowly. The power of the reactor is also relatively slow; moreover, when the power of the reactor n...

[0003] At present, the control method for the power of the pressurized water reactor core is generally to change the reactivity of the core by adjusting the boron concentration in the coolant of the primary circuit; however, this control method needs to inject Water or high-concentration boron solution is used to dilute or borate the coolant; since it takes a certain amount of time for the coolant in the primary circuit to mix evenly after each dilution or boronization, the boron concentration of the primary coolant changes slowly. The power of the reactor is also relatively slow; moreover, when the power of the reactor needs to be raised and lowered frequently, if this rise and fall is tracked by adjusting the boron concentration alone, frequent dilution and boronization of the primary coolant must be carried out, and the process is relatively cumbersome and operator burden, resulting in less efficient control of the PWR core
