<p>The present invention relates to an emergency collecting device for a nuclear power plant and, more specifically, to an emergency collecting device for a nuclear power plant, which is installed on an emergency pipe line separately arranged at one side of a containment building where a nuclear reactor is housed to collect leaked high-temperature and high-pressure water and gas, and radioactive substances included in the same in the containment building if the high-temperature and high-pressure water and gas that include the radioactive substances are leaked due to damage of a pipe and a pressure container that are connected to the nuclear reactor. The emergency collecting device for a nuclear power plant comprises: a water collecting device unit which has one side connected to an emergency pipe line and which is provided to reduce a pressure of high-temperature and high-pressure water or gas that is introduced from the emergency pipe line and to collect radioactive substances included in the same by water; a filtration membrane which has one side connected to the other side of the water collecting device unit and which is provided to filter particulate radioactive substances introduced from the water collecting device unit; a filtration device unit which includes a metal layer to binarize or absorb the radioactive substances by an oxidation-reduction reaction and an absorption reaction between fine radioactive substance particles and metal; and an ion exchange resin unit which has one side connected to the other side of the filtration device unit and which is provided to remove ionic radioactive substances among the radioactive substances introduced from the filtration device unit, thereby providing safety of the containment building, preventing environmental pollution, and reducing operation restart time of the nuclear power plant by inducing the high-temperature and high-pressure water and gas, and the radioactive substances included in the same into separate space to be efficiently treated when the high-temperature and high-pressure water and gas, and the radioactive substances included in the same in the damaged pipe or pressure container are leaked into the containment building where the nuclear reactor is housed due to damage of the pipe or the pressure container that is connected to the nuclear reactor.</p> |
