| 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,本文研究了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823K时,发生点蚀,当温度高于823K时,发生溶解。

| Abstract: | 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 chemical stable and unfeasible to fire or explore when contacting with air or water. In this paper we examined the chemical reactions between Sn and 304 stainless steel, which is widely used as primary circuit pipeline materials in fast reactor, and discussed the effect of temperature on the corrosion behavior between 304 stainless steel and liquid Sn. The results showed that pitting happened when the temperature was lower than 823K, and dissolution happened when the temperature was higher than 823K. |
