浅析某核电厂汽轮机进水的原因及应对措施

目前,我国核电厂大部分都属压水堆,二回路主蒸汽参数较低,再加上目前核电厂参与调峰运行的大背景,汽轮机进水事故发生概率增大。文章结合某核电厂实际情况,阐述了汽轮机进水事故的危害,分析了汽轮机进水事故发生的可能原因及该厂的一些针对设计和预防措施。最后总结了汽轮机进水事故发生的一些现象和可以采取的处理措施。

Now almost Nuclear power stations belong to pressurized water reactor.The secondary loop steam parameters are low.Influence 0f Peaking Operation Mode,the water into steam turbine occurrence probability increases.In this paper,combined with the actual situation of our plant,this paper expounds the harm of the steam turbine inlet accident,analyzes the possible reasons of the occurrence of the steam turbine and the design and preventive measures of our factory.At the end of the last,the phenomena of the water accident of steam turbine and the treatment measures are summarized.
