A passive safety facility is provided. The passive safety facility comprises: a cooling unit cooling first fluid discharged from a reactor coolant system or a vapor generator installed in the reactor coolant system and second fluid in a housing unit; a circulation inducing spraying unit spraying the first fluid discharged from the reactor coolant system or the vapor generator to the cooling unit, having a part partially opened toward the inside of the housing unit so that the second fluid is inserted by pressure drop generated when the first fluid is sprayed, and spraying the inserted second fluid along with the first fluid; and a filter unit connected with an outlet of the cooling unit to filter non-condensable gas discharged from the cooling unit and collecting a radioactive matter filtered from the non-condensable gas. 본 발명은, 원자로냉각재계통으로부터 방출되거나 상기 원자로냉각재계통의 내부에 설치되는 증기발생기로부터 방출된 제1유체를 격납부 내부의 제2유체와 함께 냉각하도록 형성되는 냉각부; 상기 원자로냉각재계통 또는 상기 증기발생기로부터 방출된 상기 제1유체를 상기 냉각부로 분사하도록 형성되고, 상기 제1유체를 분사하면서 유발되는 압력강하에 의해 상기 제2유체를 인입시키도록 적어도 일부가 상기 격납부의 내부를 향해 개방되어 있으며, 인입된 상기 제2유체를 상기 제1유체와 함께 분사하는 순환유도 분사기구; 및 상기 냉각부에서 방출되는 비응축성 가스를 여과하도록 상기 냉각부의 출구에 연결되고, 상기 비응축성 가스로부터 여과된 방사성 물질을 포집하는 여과설비를 포함하는 피동안전설비를 제공한다.
