Abstract

The invention relates to the field of nuclear power plant important nuclear auxiliary systems, in particular to a nuclear power plant boric acid comprehensive management system and method. The nuclear power plant boric acid comprehensive management system comprises a boric acid preparation and storage module; a demineralized water storage module; a boric acid centralized management module which is respectively connected with the boric acid preparation and storage module and the demineralized water storage module; and a boric acid conveying and distributing module which is connected with the boric acid centralized management module. The management method comprises the following steps: monitoring the boron concentration of each user in real time, comparing the boron concentration with a target boron concentration, and sending a control signal to the boric acid preparation and storage module and the desalted water storage module; calculating required concentrated boric acid flow and desalted and deoxygenated water flow in real time; automatically controlling that the prepared and stored boric acid solution and the desalted and deoxygenated water to be prepared into the boric acid solution with the preset concentration, and feeding the boric acid solution to a destination through the conveying and distributing module. Function combination and equipment sharing are achieved, system configuration is simplified, it is guaranteed that the boric acid auxiliary system achieves multiple functions, and economical efficiency is improved.

Description

technical field

[0001] The invention relates to the field of important nuclear auxiliary systems of nuclear power plants, in particular to a boric acid comprehensive management system and method for nuclear power plants. Background technique

[0002] Since the mid-1980s, the international nuclear energy community has extensively carried out the research and development of third-generation nuclear power technology, and has achieved a variety of achievements with engineering practical value. The third-generation nuclear technology adopts the "passive" safety system, which greatly simplifies the system, equipment, and structures of the nuclear power plant, and greatly improves the safety, reliability, and economy.

[0003] China National Nuclear Corporation's million-kilowatt-class advanced pressurized water reactor "Hualong One" nuclear power unit is independently developed by China National Nuclear Corporation in order to realize the safe and efficient development of nuclear ...
