【摘要】 铅铋合金具有优异的核性能、高导热率、高沸点和化学惰性等特点，以其作为冷却剂的铅铋快中子增殖反应堆是最具发展前景的第四代先进核能系统的六种堆型之一。铅铋合金冷却剂对反应堆结构材料较强的腐蚀性是限制铅铋快堆发展的重要因素；然而，控制铅铋合金中溶解氧在特定的范围是实施结构材料在液态铅铋环境下腐蚀防护的有效手段之一，因此要求铅铋系统必须实现溶解氧的测量与控制，以保障反应堆的安全运行。近年来，随着铅铋快堆研发的深入，材料腐蚀防护关键共性技术不断突破，本文总结了面向反应堆结构材料腐蚀防护的铅铋溶解氧测量和控制技术研究进展，介绍了铅铋合金氧测氧控国内外研究现状，重点对比分析了不同氧控模式在铅铋快堆的应用前景，最后对面向铅铋快堆的氧测氧控技术的发展及应用进行了展望。更多还原

【Abstract】 Because of the excellent nuclear property, high thermal conductivity, high boiling point and chemical inertness of lead-bismuth alloy, the lead-bismuth fast breeder reactor, which use lead-bismuth alloy as the coolant, is one of the promising development prospects of Generation Ⅳ six type of reactors. Lead-bismuth eutectic(LBE) coolant is corrosive to reactor structural materials, which is an important factor limiting the development of LBE cooled reactor. Oxygen dissolved into LBE controlled in a certain range is one of the effective approaches to carry out corrosion protection of structural materials in LBE environment, so it is required that the oxygen dissolved in lead-bismuth system must be controllable and measurable to ensure the safe operation of the reactor. In recent years, with the development of LBE cooled reactor, the key common technologies on material corrosion protection continue to break through. This paper summarizes the research progress of dissolved oxygen measurement and control technology for reactor structural materials corrosion protection, introduces the research status of oxygen measurement and oxygen control at home and abroad, and focuses on the comparison and analysis of the application prospects of different oxygen control modes for LBE cooled fast reactor. Finally, the development and application of oxygen measurement and control technology for lead-bismuth fast reactor are prospected.更多还原
