Comprehensive boric acid management system and method for nuclear power plant

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 ...

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
