摘　　要：内部水淹是核电厂面临的重要风险之一,对其定量化是识别核电厂水淹风险的有效手段,也是进行内部水淹概率安全评价的基础。本文通过对国内外各种水淹事件定量化分析方法的研究,提出核电厂内部水淹事件定量化的一般方法,并定量分析了我国某900MW核电厂重要厂用水系统内部水淹事件,对国内核电厂开展内部水淹风险评估有重要参考价值。Internal flooding is an important risk to nuclear power plant,quantification of internal flooding events is not only an effective way of identifying flooding risk,but also the basis of the internal flooding probability safety assessment. The quantitative method status of internal flooding events is reviewed,and then a general method is put forward,and a 900 MW nuclear power plan services water pipe failure internal flooding events are quantified. The proposed method has important reference value for the internal flooding PSA of nuclear power plant in China.

关 键 词：内部水淹 核电厂 概率安全评价 定量化
