摘　　要：中国实验快堆三回路主蒸汽系统主要功能是将蒸汽发生器产生的蒸汽送至汽轮发电机组,辅助功能是在事故工况下排出反应堆产生的热量。调试期间多次因主蒸汽系统阀门手动操作而引起停堆,影响了系统的稳定性,增加了运行成本。本文对主蒸汽系统进行了优化设计、增加旁路管道,并对此条件下的过热器反暖操作和特殊工况下压力损失计算结果进行定性分析,确定了设计参数,优化了主蒸汽系统的工艺流程。The function of the main steam system of China Experimental Fast Reactor （CEFR） is to transfer the steam from SG to the turbine to generate power and to discharge the steam from reactor in case of accidental condition. However, the reactor automatically shut down many times due to improper operation of valves, affecting the stability of the system and increasing operation cost. In order to optimize the steam system process flow, this paper introduced the bypass and worked out the design parameters, and finally gave qualitative analysis of the calculation result in special condition.
