Abstract

장치는 비상의 경우에 있어서 기화된 냉각수를 응축하고 재순환하여 원자로를 자동으로 냉각한다. 원자로는 수납장치에 의해서 둘러싸여지며 물과 같은 냉각 액체용 저장 탱크를 구성하며 수납장치에 배출수단의 구멍을 형성하고 있다. 저장탱크는 수납 장치 내부에 배치하는 것이 바람직하며 예를 들어 열교환기에 의해서 원자로에 열적으로 연결가능하고, 저장 탱크에 있는 냉각수는 열에너지를 흡수하여 증발된다. 냉각수는 증기로 되며 수납 장치의 차가운 내부 표면상에서 응축한다. 응축된 냉각수는 중력에 의해서 아래로 흐르며 수납되어 저장 탱크로 귀환한다. 벽으로부터 응축물을 수납하기 위해서 하나이상의 홈통이 수납장치의 내부벽을 따라서 배치된다. 배관은 홈통에서 저장탱크로 응축물을 전달하기 위해서 제공된다.The device automatically cools the reactor by condensing and recirculating vaporized cooling water in the event of an emergency. The reactor is surrounded by a receiving device and constitutes a storage tank for cooling liquid, such as water, and forms a hole in the discharge device in the receiving device. The storage tank is preferably arranged inside the receiving device and is thermally connectable to the reactor, for example by a heat exchanger, and the cooling water in the storage tank absorbs thermal energy and evaporates. The coolant becomes steam and condenses on the cold inner surface of the enclosure. The condensed coolant flows down by gravity and is returned to the storage tank. One or more troughs are disposed along the inner wall of the receiver to receive the condensate from the wall. Tubing is provided to transfer condensate from the trough to the storage tank.
