Summary:The present invention relates to a nuclear reactor shutdown cooler using a heat exchanger submerged in a water bath around a nuclear reactor. More specifically, the nuclear reactor shutdown cooler using a heat exchanger submerged in a water bath around a nuclear reactor according to the present invention comprises: a water bath (10) arranged adjacent to a nuclear reactor (1) and having an apparatus coolant (C2) stored thereinside; and a shutdown cooling heat exchanger (20), installed inside the water bath (10) and submerged in the apparatus coolant (C2), for allowing a nuclear reactor coolant (C1) circulated to be supplied and the apparatus coolant (C2) of the water bath (10) to undergo heat-exchange. That is, the nuclear reactor shutdown cooler can submerge a shutdown cooling heat exchanger formed with multiple tubes in a water bath (or water tank) around a nuclear reactor for nuclear reactor shutdown cooling driving, and a nuclear reactor coolant passing the submerged tube bundle can perform shutdown cooling via heat exchange with an apparatus coolant. 본 발명에 따른 원자로 주변 수조내 침수된 열교환기를 이용한 원자로 정지냉각장치에 관한 것으로, 더욱 상세하게는 원자로(1)에 인접하여 배치되고, 기기냉각수(C2)가 저장된 수조(10); 및 상기 수조(10) 내부에 내장되어 상기 기기냉각수(C2)에 침수되고, 순환 공급되는 원자로냉각재(C1)와 상기 수조(10)의 기기냉각수(C2)를 열교환시키는 정지냉각열교환기(20);를 포함하여 구성된다. 즉 본 발명은 원자로 정지냉각 운전을 위해 원자로 주변에 위치하는 수조(또는 물탱크)에 다수의 튜브로 구성되는 정지냉각열교환기를 침수시키고, 이렇게 침수된 튜브 다발을 통과하는 원자로냉각재가 수조의 기기냉각수와의 열교환을 통하여 정지냉각을 수행할 수 있는 원자로 주변 수조내 침수된 열교환기를 이용한 원자로 정지냉각장치를 제안하고자 한다.
