Zusammenfassung:The present invention relates to a containment vessel passive cooling system of a floating nuclear power plant using a sea chest. The system includes: a floating body floating on seawater; a containment vessel provided inside the floating body; a sea chest provided in the floating body, having a space for storing seawater therein, and connected with seawater of the outside of the floating body; a connection pipe connecting the sea chest with an outer space of the containment vessel and moving the seawater of the sea chest to the outside of the containment vessel; and an isolation valve provided in the connection pipe and opening and closing the connection pipe. 본 발명은 씨체스트를 이용한 부유식 원자력발전소의 원자로격납용기 피동냉각시스템에 관한 것으로, 해수에 띄워지는 부유체; 상기 부유체 내부에 구비되는 원자로격납용기; 상기 부유체에 구비되며, 내부에 해수가 저장되는 공간이 구비되면서 상기 부유체 외부의 해수와 연통되는 씨체스트; 상기 씨체스트와 상기 원자로격납용기의 외측 공간을 연결하면서, 상기 씨체스트의 해수를 상기 원자로격납용기의 외측으로 이동시키는 연결배관; 상기 연결배관에 구비되면서, 상기 연결배관을 개폐하는 격리밸브;를 포함하는 것을 특징으로 하는 것이다.
