The control and detection of dissolved oxygen in liquid sodium is important for the mitigation of impurity driven corrosion in containment components used in sodium-cooled fast reactor (SFR) environments. Oxygen purification systems are also necessary in smaller institutions to facilitate benchtop-scale testing of future SFR instrumentation. With interest in increasing laboratory-scale SFR research, this paper focuses on the design and demonstration of a safe and cost-effective purification loop using a cold trap (CT) and a plugging meter (PM) to control and measure oxygen levels. The demonstration of the purification system’s effectiveness to manipulate oxygen concentration was made through a series of validation experiments at several CT set-points in the range of $8–28[\mathit{wppm}]$. Agreement below $14[\mathit{wppm}]$ with a relative error less than 1.8% was observed. These results indicate that an accessible oxygen controlled sodium system can be safely designed and operated at relatively low capital investment.

液态钠中溶解氧的控制和检测对于减轻钠冷快堆（SFR）环境中使用的安全壳组件中的杂质驱动腐蚀非常重要。在较小的机构中，氧气净化系统也是必需的，以便于对未来的SFR仪器进行台式规模的测试。随着对实验室规模SFR研究的兴趣的增加，本文着重于设计和演示使用冷阱（CT）和测堵仪（PM）来控制和测量氧气水平的安全且经济高效的净化回路。通过一系列的验证实验，通过一系列的验证实验，证明了净化系统控制氧气浓度的有效性。$8–\mathrm{28岁}[\mathit{百万分之几}]$。以下协议$14[\mathit{百万分之几}]$观察到相对误差小于1.8％。这些结果表明可以以相对较低的资本投资来安全地设计和操作可及的氧控制钠系统。
