不锈钢与哈氏合金在超临界水中的腐蚀与防护研究

Corrosion and Protection of Stainless Steel and Hastelloy in Supercritical Water

随着我国能源结构的调整,核电大力发展已经基本呈现出必然的趋势,而第四代堆型的研发为确保核能高效利用指明了方向。超临界水堆作为第四代核能堆型中唯一的水冷堆,其良好的综合性能包括了可持续性、经济性、高效率性等,是国家未来水冷堆先进技术发展的必然结果。其当前的发展也遇到一些棘手的问题,最为突出的是材料的耐腐蚀性。本文将简单介绍超临界水堆及分析几种合金在其中的腐蚀情况。

With the adjustment of China's energy structure,the vigorous development of nuclear power has basically shown the inevitable trend,and the research and development of the fourth generation of reactors point out the direction of ensuring the efficient use of nuclear energy. As the only water-cooled reactor in the fourth generation of nuclear power reactor,the excellent comprehensive performance of the supercritical water reactor,including sustainability,economy and high efficiency,is the inevitable result of the development of the advanced technology of the country's water-cooled reactor. However,its current development also encountered some urgent problems,the most prominent is the corrosion resistance of the material. This article will briefly introduce the supercritical water reactor and analyze the corrosion of several alloys.
