摘要
Sn是一种低熔点金属,其导热性高可用作快中子反应堆中的液体冷却剂。与目前所使用的液态钠冷却剂相比,Sn具有更好的化学稳定性及遇水或空气不易燃烧的特点。在快中子反应堆中,不锈钢是应用广泛的主回路管道,本工作研究了Sn与304不锈钢的化学反应,讨论了温度对304不锈钢在液态Sn中腐蚀行为的影响。结果表明,当温度低于823 K时,发生点蚀,当温度高于823 K时,发生溶解。
Sn is a kind of low melting point metal and can be used as a liquid coolant due to its higher thermal conductivity.Compared with the currently used sodium liquid coolant,Sn is more chemically stable and unfeasible to fire or explore when contacting with air or water.The chemical reactions between Sn and 304 stainless steel that is widely used as primary circuit pipeline materials in fast reactor were researched,and the effect of temperature on the corrosion behavior between 304 stainless steel and liquid Sn was discussed.The results show that pitting happens when the temperature is lower than 823 K,and dissolution happens when the temperature is higher than 823 K.
