钠冷快堆的许多部件处于高温钠介质中,又受到各种应力的作用,这已成为限制部件使用寿命的重要原因之一,而焊接件往往是其中的薄弱环节。本课题的目的在于研究不锈钢焊接件在上述条件下的腐蚀行为。 Many components of sodium-cooled fast reactors are exposed to high temperatures in sodium media and are subject to a variety of stresses, which have become one of the major causes of component life limitations, and welds are often the weakest link. The purpose of this project is to study the corrosion behavior of stainless steel welded parts under the above conditions.
