| description | The present invention relates to a coolant system of a vapor generator for supplying a coolant to a vapor generator in the event of a critical accident in a nuclear power plant and a method for supplying a coolant to a vapor generator in the event of a critical accident in a nuclear power plant. The coolant system of a vapor generator having a housing, a U-shaped tube placed inside the housing, and a partition plate dividing the inside of the housing into a receiving space for primary coolant supplied and discharged through the U-shaped tube and a receiving space for secondary coolant in contact with the U-shaped tube comprises: a take-out pipe that takes out a small amount of secondary coolant during normal operation of a nuclear power plant and forms a supply path for the secondary coolant to increase the level of the secondary coolant from the partition plate in the event of a critical accident in the nuclear power plant; a coolant storage tank that is connected to the take-out pipe in the event of a critical accident in the nuclear power plant and stores the secondary coolant supplied from the take-out pipe to the vapor generator; and a mobile pump that is selectively disposed between the take-out pipe and the coolant storage tank to pump the secondary coolant stored in the coolant storage tank to the take-out pipe in the event of a critical accident in the nuclear power plant.
본 발명은 원자력 발전소의 중대 사고 시 냉각재를 증기발생기로 공급하는 증기발생기의 냉각재 계통 및 원자력 발전소의 중대 사고 시 증기발생기에 냉각재를 공급하는 방법에 관한 것이다. 본 발명에 따른 하우징과 하우징의 내부에 배치되는 U-튜브와 하우징의 내부를 U-튜브로 공급되어 배출되는 1차 냉각재의 수용 공간과 U-튜브와 접촉되는 2차 냉각재의 수용 공간으로 구획하는 구획판을 갖는 증기발생기의 냉각재 계통은 원자력 발전소의 정상 운전 시 소량의 2차 냉각재를 취출하고 원자력 발전소의 중대 사고 시 구획판으로부터 2차 냉각재의 수위가 증가하도록 2차 냉각재의 공급로를 형성하는 취출수 배관, 원자력 발전소의 중대 사고 시 취출수 배관에 연결되며 취출수 배관으로부터 증기발생기로 공급되는 2차 냉각재가 저장된 냉각재 저장탱크 및 취출수 배관과 냉각재 저장탱크 사이에 선택적으로 배치되어 원자력 발전소의 중대 사고 시 냉각재 저장탱크에 저장된 2차 냉각재를 취출수 배관으로 펌핑하는 이동형 펌프를 포함하는 것을 특징으로 한다. |
