Nuclear power plant boric acid integrated management system and method

Abstract

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. The nuclear power plant boric acid comprehensive management system includes: boric acid preparation and storage module; demineralized water storage module; boric acid centralized management module, respectively connected with boric acid preparation and storage module, demineralized water storage module; boric acid delivery and distribution module, and boric acid centralized management module connection. The management method includes: monitoring the boron concentration of each user in real time, comparing the target boron concentration, sending a control signal to the boric acid preparation storage module and the desalinated water storage module; real-time calculation of the required concentrated boric acid flow rate and desalination and deoxygenation water flow rate; Automatic control configures the prepared and stored boric acid solution and desalted and deoxygenated water into a boric acid solution with a preset concentration, and the delivery and distribution module delivers it to the destination. The invention realizes function combination and equipment sharing, simplifies system configuration, ensures multiple functions of boric acid auxiliary system and improves economy.

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 ...

AI Technical Summary

Problems solved by technology

[0005] In the traditional design idea, due to the existence of too many intermediate links, such as the storage of desalinated and oxygenated water, the preparation of boric acid and water through flow adjustment, etc., and the complexity of equipment, boron and water supply systems, chemical and volume control systems, The emergency boron injection system involves a separate set of devices. The various equipment and plant supporting facilities thus configured have caused a disadvantage in the overall economics of the power plant and increased the burden of operation and maintenance, such as: frequent damage to the floating roof of the supply water tank failure, resulting in reoxygenation of the water in the tank, frequent water changes and maintenance operations negatively impacting plant economics and availability
