摘要
介绍了核电站整体抗震安全现状,简要分析了核安全相关抗震技术的发展进程,尤其是各国对核电站抗震性能的反思和改进,指出对核电汽轮机进行抗震分析的必要性及重要性。重点介绍了核电汽轮机抗震分析方法的发展,以及各方法的详细内容和应用情况,分析了各方法的优点和不足并提出了根据实际情况合理选择适用方法的建议。这些分析和建议有助于推动核电汽轮机抗震分析的进一步发展。
At first, the current status of seismic safety for nuclear power ptam kilt1 , .o e development of anti-seismic technology as for nuclear safety-related objects is introduced, meanwhile, especially for the worldwide rethink and improvement aiming at the NPP＇ seismic performance after some nuclear accidents caused by earthquake, it is necessary and important for nuclear steam turbines to carry out seismic analysis. Secondly, the seismic analysis methods focused on nuclear steam turbine are stated in terms of the development and application of each method, their advantages and disadvantages are compared and analyized. At the end, some suggestions to choose the proper method according different situations are proposed, which could help to promote the further development of seismic analysis for nuclear steam turbines.
