超临界核电厂汽轮机和热力系统的研究

Research on SCWR Turbine and Thermal System

超临界核电机组的汽轮机为超临界、冲动式,其所有转子叶片材料均采用成熟的火力发电厂超临界机组叶片材料,并采用外来的清洁蒸汽作为密封蒸汽。机组的热力系统增加了启停系统,在启动和停止阶段为超临界核反应堆提供所需的冷却剂流量,适应机组滑压启动要求。本文对超临界核电机组的汽轮机设计和热力系统的总体方案进行了详细介绍。

The turbine of SCWR is supercritical and impulse which rotors are made of materials maturely used in the turbines of supercritical thermal power plants. The turbine＇s seal steam is from clean steam source. In order to realize the sliding pressure startup, the thermal system includes a startup and shut down system which supply sufficient flow for the reactor in startup and shut down phase. This paper describes the turbine and thermal system of SCWR.
