在加速器驱动洁净核能系统(ADS)中,金属钨和钠冷快堆分别是产生源中子靶件和次临界反应堆的一种可能选择,因此,研究钨与钠的化学相容性特征十分必要。材料与介质的相容性特征受很多因素影响,材料加工工艺就是重要的影响因素之一。本项工作对旋锻钨和抛光钨与钠的化学相容性进行试验研究,比较其相容性差异,对钨与钠相容性的机理及其影响因素进行初步分析和探讨。
In Accelerator Driven Clean Nuclear Energy Systems (ADSs), metallic tungsten and sodium cold fast reactors are a possible alternative for producing source and sub-critical reactors, respectively, and therefore it is necessary to study the chemical compatibility of tungsten and sodium . Material and media compatibility characteristics are affected by many factors, material processing technology is one of the important factors. In this work, the chemical compatibility of tungsten for tungsten and polished tungsten was experimentally studied. The compatibility of tungsten and sodium were compared. The compatibility mechanism between tungsten and sodium and its influencing factors were analyzed and discussed.
