Title (EN) CORE CATCHER HAVING AN INTEGRATED COOLING PATH
(FR) RÉCUPÉRATEUR DU CŒUR À VOIE DE REFROIDISSEMENT INTÉGRÉE
(KO) 통합 냉각유로를 갖춘 코어 캐쳐
Abstract: front page image
(EN)The object of the present invention is to provide a core catcher having an integrated cooling path, which comprises a structure able to effectively collect, retain and cool molten core material discharged through a damaged part of a nuclear reactor pressure container during a major incident in a nuclear power station. To this end, the present invention is a core catcher which is disposed underneath the nuclear reactor pressure container in order to retain and cool molten core material discharged through a damaged part of the nuclear reactor pressure container and prevent interaction between the molten core material and the pressure-holding structure of the reactor building during a major incident in the nuclear power station, and which comprises: a main container in the shape of an inverted roof which is provided underneath the nuclear reactor pressure container and collects the molten core material; and a lower structure which is disposed below and outside the main container with supports disposed at scattered points placed in between, thereby forming a cooling path having a predetermined spacing for eliminating the heat of the molten core material.
(FR)L'invention concerne un récupérateur du cœur pourvu d'une voie de refroidissement intégrée, qui comprend une structure capable de recueillir, de conserver et de refroidir efficacement les matériaux du cœur fondus évacués d'une partie endommagée d'un caisson de réacteur nucléaire sous pression pendant un incident majeur dans une centrale nucléaire. Pour ce faire, l'invention concerne un récupérateur du cœur qui est disposé en-dessous du caisson de réacteur nucléaire sous pression afin de retenir et de refroidir les matériaux du cœur fondus évacués d'une partie endommagée du caisson de réacteur nucléaire sous pression, et d'empêcher l'interaction entre les matériaux du cœur fondus et la structure de maintien de pression du bâtiment de réacteur pendant un incident majeur dans le réacteur nucléaire. Le récupérateur du cœur comprend: un récipient principal en forme de toit inversé qui est placé en-dessous du caisson de réacteur nucléaire et qui recueille les matériaux du cœur fondus; et une structure inférieure qui est placée en-dessous et à l'extérieur du caisson principal dotée de supports disposés à des points épars situés entre eux, ce qui forme une voie de refroidissement à espacement prédéterminé pour éliminer la chaleur des matériaux du cœur fondus.
(KO)본 발명은 원자력발전소에서 중대사고 발생시 원자로 압력용기 파손부를 통해 방출되는 노심용융물을 효과적으로 수집, 보유 및 냉각할 수 있는 구조로 이루어진 통합 냉각유로를 갖춘 코어 캐쳐를 제공함에 그 목적이 있다. 이를 구현하기 위한 본 발명은, 원자력발전소에서 중대사고시 원자로 압력용기의 파손부를 통해 방출된 노심용융물을 보유 및 냉각시켜 상기 노심용융물과 원자로건물 압력 유지 구조물의 상호 반응을 방지하기 위해 원자로 압력용기 하측에 설치되는 코어 캐쳐에 있어서, 상기 원자로 압력용기 하측에 설치되어 노심용융물을 수집하는 역지붕형의 본체 용기와, 상기 본체 용기의 하부 및 외측에 산점 배치된 지지대를 사이에 두고 배치되어 상기 노심용융물의 열을 제거하기 위한 일정한 간격의 냉각유로를 형성하는 하부 구조물을 포함한다.
