摘　　要：介绍了西门子设计制造先进大功率核电汽轮机的长期运行经验,并发展半速饱和蒸汽核电汽轮机,功率达1700MW,末级长叶片高度为1829mm,从设计、工艺、材料选择等方面论述了提高机组出力、提高机组效率、减少腐蚀的方法,其中包括套装叶轮设计、3DSTM叶片技术、高压透平和低压透平等.The paper introduces long operational experience of nuclear power plant at Siemens which has been developing the half speed saturated steam turboset for high power output up to 1700MWel with the longest blade length up to 1829mm/72 inch. The advanced design methods, process and appropriate material selection have been proved to increase the highest power output and efficiency, decrease erosion and corrosion. The features of the shrunk-on disk design, 3DSTM blade technique, high pressure turbine and low pressure turbine are also described in the paper.
