Development of Steels for Nuclear Power and Its Gen. Ⅳ Materials

论述了核电用钢的发展现状和第四代核电用钢的设计理念。着重分析了目前发展核电尤其是第四代核电的必要性，紧迫性以及第四代核电抗辐射、耐高温的作用机理，最后，将目前国际上较为普遍的第四代核电用钢生产工艺过程做了简要介绍，分析了应该注意的研究重点和研究的路线。

This paper discusses the development status of steels for nuclear power and the design principles of its Gen. Ⅳ materials, emphatically analyzes the necessity and urgency to develop the nuclear power, especially Gen. Ⅳ nuclear power, and carries out the analysis on the radioresistant and fireresistant mechanisms of Gen. Ⅳ steels for nuclear power, finally, the paper gives a brief introduction on the production process of the common Gen. Ⅳ steels for nuclear power in the world, and analyzes the study emphasis and route which should to be noted.
