Description
技术领域technical field
本发明适用于新型核工业和核技术领域，主要应用于加速器驱动次临界堆(ADS)和先进反应堆液态金属冷却剂氧含量在线控制。The invention is applicable to the fields of new nuclear industry and nuclear technology, and is mainly applied to the on-line control of the oxygen content of the liquid metal coolant in accelerator-driven subcritical reactors (ADS) and advanced reactors.
背景技术Background technique
液态铅铋合金LBE(Lead bismuth eutectic)是加速器驱动的次临界系统(ADS)中散裂靶的首选材料和先进快堆的冷却剂重要候选材料。由于液态铅铋特殊的热物理性质和化学性质，例如低熔点(123.5℃)，高沸点(1670℃)，高热导率，低蒸汽压并且与空气和水没有剧烈的反应等，液态铅铋目前作为ADS散裂靶和先进快堆的冷却剂在世界范围内广泛研究。Liquid lead bismuth alloy LBE (Lead bismuth eutectic) is the preferred material for spallation targets in accelerator-driven subcritical systems (ADS) and an important candidate material for coolants in advanced fast reactors. Due to the special thermophysical and chemical properties of liquid lead-bismuth, such as low melting point (123.5°C), high boiling point (1670°C), high thermal conductivity, low vapor pressure and no violent reaction with air and water, liquid lead-bismuth is currently As a coolant for ADS spallation targets and advanced fast reactors, it has been extensively studied worldwide.
但其对钢材的腐蚀性成为其广泛运用的最大的制约。液态铅铋在中高温环境下对直接暴露在其中的钢材具有很强腐蚀性。在液态铅铋中，为了防止材料的腐蚀必须存在一定活性的溶解氧，溶解氧的活性必须足够多以避免材料氧化层的热力学溶解，起到保护材料的作用。但同时要低于PbO生成的氧活性，如果超出就会造成固态PbO析出，形成氧化物残渣，污染整个液态铅铋系统。总之，液态铅铋的操作条件必须要保证材料表面氧化层的动力学平衡和防止氧化物沉淀生成。由于以上原因，监测和控制液态铅铋中的溶解氧是很有必要的。目前控制氧浓度的方法主要有气相法和固相法两种。公开发表的文献显示仅在一些回路装置中有固相氧控的应用。已有的一种适用于实验固相氧控装置(专利已公开)，液态铅铋是静态的，适用于固相氧控机理研究，未来固相氧控将运用至铅基反应堆中，铅铋的工况是流动的。铅铋流动工况下实现固相氧控的技术难点在于PbO颗粒溶解与沉积过程中对流经质量交换器中铅铋温度和流量的精确控制和PbO颗粒的防毒害(腐蚀杂质沉积在PbO颗粒表面，PbO颗粒溶解与沉积功能将失效)。本发明将克服这些难点。发展一种流动工况下液态重金属氧浓度控制固液交换反应装置，既适合于相关机理研究，同时具有较大的工程应用价值。However, its corrosiveness to steel has become the biggest constraint for its wide application. Liquid lead-bismuth is very corrosive to steel directly exposed to it in a medium-high temperature environment. In liquid lead bismuth, in order to prevent material corrosion, there must be a certain amount of active dissolved oxygen, and the activity of dissolved oxygen must be sufficient to avoid the thermodynamic dissolution of the oxide layer of the material and protect the material. But at the same time, it should be lower than the oxygen activity generated by PbO. If it exceeds, it will cause solid PbO to precipitate, form oxide residues, and pollute the entire liquid lead-bismuth system. In short, the operating conditions of liquid lead-bismuth must ensure the kinetic balance of the oxide layer on the surface of the material and prevent the formation of oxide precipitation. For the above reasons, it is necessary to monitor and control the dissolved oxygen in liquid lead bismuth. At present, there are two main methods to control the oxygen concentration: gas-phase method and solid-phase method. Published literature shows the use of solid phase oxygen control only in some loop setups. There is an existing solid-phase oxygen control device suitable for experiments (the patent has been published). The liquid lead-bismuth is static and suitable for the study of the solid-phase oxygen control mechanism. In the future, the solid-phase oxygen control will be applied to lead-based reactors. The lead-bismuth The operating conditions are fluid. The technical difficulty of realizing solid-phase oxygen control under the flow condition of lead and bismuth lies in the precise control of the temperature and flow rate of lead and bismuth flowing through the mass exchanger during the dissolution and deposition of PbO particles and the anti-poisoning of PbO particles (corrosion impurities are deposited on the surface of PbO particles , the PbO particle dissolution and deposition functions will be invalid). The present invention will overcome these difficulties. The development of a liquid heavy metal oxygen concentration controlled solid-liquid exchange reaction device under flowing conditions is not only suitable for related mechanism research, but also has great engineering application value.
