Description

일체형원자로 피동냉각장치{Passive cooling apparatus for nuclear reactor}Integrated nuclear reactor passive cooling apparatus {Passive cooling apparatus for nuclear reactor}

본 발명은 일체형원자로 피동냉각장치에 관한 것이다.The present invention relates to a passive cooling system for an integrated nuclear reactor.

일체형 원자로의 격납용기는 사고 때 내부에서 발생하는 노심의 열을 제거하기 위하여 저수 풀에 잠겨져 있다. 작동원리는 격납용기 내부에서 사고가 발생하여 증기가 배출되면 외벽이 상대적으로 차가운 저수 풀에 잠겨 있는 격납용기의 내벽에서 응축되고 전달된 열은 격납용기를 통해 저수 풀로 전달된다. 이후 저수 풀의 온도가 일정온도에 도달하면 증발하게 되는데 저수 풀의 냉각수가 모두 증발할 때까지 수랭을 실시하게 된다. 냉각수가 모두 증발하게 되면 공랭으로 격납용기가 냉각되는데 이때 냉각 능력이 현저하게 저하되는 문제점이 있다.The containment vessel of an integrated nuclear reactor is submerged in a water storage pool to remove core heat generated inside in the event of an accident. The operating principle is that when an accident occurs inside the containment vessel and steam is discharged, it is condensed on the inner wall of the containment vessel where the outer wall is submerged in a relatively cold water storage pool, and the transferred heat is transferred to the water storage pool through the containment vessel. Thereafter, when the temperature of the storage pool reaches a certain temperature, it evaporates, and water cooling is performed until all of the cooling water in the storage pool evaporates. When all of the cooling water evaporates, the containment vessel is cooled by air cooling, and at this time, there is a problem in that the cooling capacity is significantly lowered.
