CEFR一回路钠净化系统是一回路冷却剂边界的一部分,在正常运行时,该系统从反应堆主容器冷池取钠,钠经省热器冷却进入冷阱净化,然后返回省热器加热,最后回到主容器的冷池。本文根据CEFR一回路钠净化系统工艺间内管道和设备的布置,以及通风系统进出口的位置,建立发生事故的工艺间 The CEFR primary loop sodium purification system is part of the primary coolant boundary. During normal operation, the system takes sodium from the cold reservoir of the main reactor vessel and the sodium is cooled by the economizer into the cold trap to purify it before returning to the economizer for heating and finally Back to the main container of the cold pool. According to the arrangement of piping and equipment in the process of sodium purification system in CEFR No.1 circuit and the position of the import and export of ventilation system,
