次临界能源包层非能动安全系统
摘要：
本发明公开一种次临界能源包层非能动安全系统，包括密封地贯穿安全壳并对应于次临界能源包层设置的非能动堆芯注入系统，用以对次临界能源包层进行注水；密封地贯穿安全壳的二次侧非能动余热导出系统，二次侧非能动余热导出系统连通设于安全壳内的蒸汽发生器的出口及入口，用于将堆芯余热导出至安全壳外；至少一组密封地贯穿安全壳的非能动安全壳冷却系统，用以将安全壳内的热量导出至安全壳外。本发明能够完全非能动的实现次临界能源包层的余热排出需求，提高系统的安全性及可靠性。
摘要（英）：

The invention discloses a passive safety system for subcritical energy claddings. The passive safety system comprises passive core injection systems, secondary side passive residual heat removal systems and one or more groups of passive containment vessel cooling systems, wherein each passive core injection system penetrates through a containment vessel in a sealed manner, corresponds to one subcritical energy cladding, and is used for injecting water into the subcritical energy cladding; each secondary side passive residual heat removal system penetrates through the containment vessel in a sealed manner, is communicated with the output and the input of a corresponding steam generator arranged in the containment vessel, and is used for removing core residual heat out of the containment vessel; at least one group of passive containment vessel cooling system penetrates through the containment vessel in a sealed manner and is used for removing heat in the containment vessel out of the containment vessel. Through the adoption of the passive safety system, the residual heat removal requirement of each subcritical energy cladding can be completely met in a passive manner, so that the system safety and the reliability are improved.
