内部水淹是威胁核电厂安全的风险源之一。根据国内外核电厂内部水淹防护设计的标准及实践，归纳提炼出具有工程参考意义的内部水淹危害性分析方法(源方法和设备分析方法)，并以国内百万千瓦级压水堆核电厂特定房间为研究对象，采用源方法进行水淹危害性分析。分析结果表明该房间内的水淹对电厂安全不构成威胁，验证了内部水淹危害性分析方法的合理性和有效性。

Internal flooding is a major risk threatening the safety of nuclear power plant (NPP).Based on the standards and practices of internal flooding protection design for nuclear power plant at home and aboard,the methods of internal flooding hazard analysis (source analysis method and equipment analysis method)are summarized,which are useful for the protection of internal flooding practically. Then the typical example,internal flooding hazard of the representative room of 1000 MWe PWR NPP is analyzed by using the source analysis method,and the analysis result shows that the internal flooding in that room does not pose a threat to the safety of nuclear power plant. The analysis process can also verify the rationality and validity of the method of internal flooding hazard analysis.
