| 摘 要： | 基于小型模块化压水堆设计特点,分别采用确定论方法和概率论方法分析了事故工况下的应急堆芯冷却系统配置策略。初步分析表明:确定论方法和概率论方法对于安注箱(ACC)的配置需求存在明显差异;在确保安全目标实现的前提下尽可能简化应急堆芯冷却系统设计,建议可取消安全级的ACC,在非能动堆芯补水箱(CMT)失效后利用其他已有注水水源来平衡设计,如能动余热排出系统增设换料水箱安注功能。

| Abstract: | In this study, based on the design characteristics of the small modular PWR, the emergency core cooling system (ECCS) scheme was analyzed for accident cases by applying the deterministic and probabilistic methods. The primary analysis shows that there is quite different requirement for the system scheme of the accumulator by deterministic and probabilistic methods. When the safety goal is ensured, it is suggested to eliminate the safety class accumulators (ACC) for ECCS simplification and other existing source water, such as IRWST in residual remove system, can be used after CMT failure. |
