Abstract Oxygen control is one of the key technologies to limit corrosion or coolant oxidation in lead bismuth eutectic cooled nuclear reactors. In this paper, we show that a stirred bubble column reactor can be an efficient tool for addition and extraction of dissolved oxygen from lead-bismuth eutectic. The design criteria and the resulting layout of the HELIOS3 reactor are detailed and typical results obtained are described. Dissolved oxygen extraction rates are only given at high oxygen activity, as dissolved corrosion products and oxides can strongly influence the rate of addition or extraction of dissolved oxygen at low oxygen activity.

HELIOS3：用于在铅铋共晶中添加氧或还原氧的搅拌泡罩塔

摘要 氧控制是限制铅铋共晶冷却核反应堆腐蚀或冷却剂氧化的关键技术之一。在本文中，我们表明搅拌鼓泡塔反应器可以成为从铅铋共晶中添加和提取溶解氧的有效工具。详细介绍了 HELIOS3 反应堆的设计标准和最终布局，并描述了获得的典型结果。溶解氧提取率仅在高氧活度下给出，因为溶解的腐蚀产物和氧化物会强烈影响低氧活度下溶解氧的添加或提取率。
