摘要： The present invention relates to an apparatus for filtering a radioactive gas generated from nuclear fuel leaked in an accident inside a nuclear power plant and more particularly, to an apparatus for filtering to prevent contamination inside a containment building. The apparatus for filtering a radioactive gas in a containment building comprises a suction pipe for introducing the radioactive gas generated from a core melt by the pressurization caused by the high pressure of a reactor cavity; and a filtration unit for removing the radioactive gas introduced through the suction pipe by a stepwise dry and wet process and discharging a contaminant-removed safe gas to the outside of the containment building.
According to the present invention, contamination of facilities and atmosphere of the containment building is prevented before being discharged to the outside of the building by connecting the outer circumferential surface of the upper portion of the reactor cavity to the filtration unit through the suction pipe. In addition, there is an advantage of increasing the filtration rate of the radioactive gas in a dual mode of a dry filter using the heat and pressure of the reactor cavity and a wet filter using the refueling water storage tank (IRWST) in the containment building with the cooling water.
