Embodiment 1

[0052] This embodiment provides a figure 1 Shown is a boric acid integrated management device system for a nuclear power plant, the device system includes a demineralized water storage device, a boric acid preparation and storage device, and a boric acid delivery and distribution device that are connected in sequence;

[0053] The boric acid preparation and storage device is a cleaning pool in a nuclear power plant;

[0054] The boric acid delivery and distribution device is used to deliver the prepared boric acid solution with preset concentration to the destination.

[0055] The top of the boric acid preparation and storage device is provided with a feeding port, and a dust cover is provided above the feeding port. A greenhouse is arranged above the dust cover.

[0056] A submersible pump is arranged at the bottom of the boric acid preparation and storage device.

[0057] The demineralized water storage device includes a demineralized water supply source for nuclear power...

Embodiment 2

[0062] This embodiment provides a system for a comprehensive boric acid management device for a nuclear power plant. The only difference between the system for a comprehensive boric acid management device for a nuclear power plant and the first embodiment is that the greenhouse above the dust cover is omitted in this embodiment.

Embodiment 3

[0064] This embodiment provides a system for a comprehensive boric acid management device for a nuclear power plant. The only difference between the system for a comprehensive boric acid management device for a nuclear power plant and the first embodiment is that this embodiment omits an external demineralized water source.

Abstract

The invention provides a boric acid comprehensive management device system for a nuclear power unit and a boron preparation method. The boron preparation device system comprises a demineralized water storage device, a boric acid preparation and storage device and a boric acid conveying and distributing device which are connected in sequence, the boric acid preparation and storage device is a cleaning pool in the nuclear power unit; and the boric acid conveying and distributing device is used for conveying the prepared boric acid solution with the preset concentration to a destination. The boric acid comprehensive management device system for the nuclear power unit provided by the invention can effectively solve the problems of rapid dissolution of boric acid in demineralized water and rapid transmission of a boric acid solution, effectively shortens the preparation period of the boric acid solution, and saves equipment purchase, installation and labor costs.

Description

technical field [0001] The invention relates to the technical field of nuclear power, relates to a boron producing device system, and in particular relates to a boric acid comprehensive management device system for a nuclear power plant and a boron producing method. Background technique [0002] After the AP1000 nuclear power plant is loaded and before the reactor is critical, it is necessary to supplement the spent fuel pool, fuel transport channel, and charging pool with boron-containing water. The main purpose is to absorb neutrons, prevent the criticality of fuel assemblies, and provide the necessary biological Shielded to ensure the safety of plant staff. The first refueling requires the injection of boron-containing water into the relevant systems of the nuclear power plant, including the reactor building fuel pool and the refueling water tank. [0003] CN 104045094A discloses a boron producing device and a boron producing method for a nuclear power plant. The boron p...
