摘　　要：辅助蒸汽系统作为M310堆型核电站的辅助系统,在核电站启动、运行和停运期间为相关用户提供低压蒸汽。STR系统作为辅助蒸汽系统一个子系统,在电站正常运行期间,通过主蒸汽对另外一侧的水加热来产生辅助蒸汽,并确保辅助蒸汽和主蒸汽隔离。由于存在经济性和辐射防护等问题,是否设置STR系统一直存在争议。据此,本文给出了4台M310机组辅助蒸汽系统设计方案之一,即4台机组共用1&2机组STR系统,并对该方案进行了详细分析和研究。As an auxiliary system of M310 nuclear power plant, the auxiliary steam system supplies low pressure steam for related users during the startup, normal operation and shutdown of the plant. During normal operation, the STR system, as a subsystem of the auxiliary steam, provides low pressure steam by primary steam heating secondary water. By this way, auxiliary steam can keep isolated with the primary steam. Due to some economic and radiation protection problems, there is always dispute about whether the STR shall be set up. So this paper provides a design plan and detailed analysis for the auxiliary steam system of four M310 plants, i.e. four units sharing the STR of Unit 1＆2.
