STATIC NUCLEAR REACTOR CONTAINMENT VESSEL HEAT REMOVAL SYSTEM AND NUCLEAR POWER PLANT

To suppress reduction in heat removing performance of a static nuclear reactor containment vessel cooling facility only by static force without using power, etc., even when non-condensable gas such as nitrogen or hydrogen is present.SOLUTION: A static nuclear reactor containment vessel heat removal system comprises: a heat-exchanger installed outside a nuclear reactor containment vessel; a steam drawing pipeline where one end is connected to the heat-exchanger and the other end is located inside a dry well in the nuclear reactor containment vessel to draw steam inside the dry well into the heat-exchanger; a condensed water exhaust pipe connecting from the heat-exchanger to a suppression pool inside the nuclear reactor containment vessel; and a steam cooling pool inside which cooling water is filled and the heat-exchanger is stored and arranged. In the static nuclear reactor containment vessel heat removal system, a non-condensable gas separation filter for separating the steam and the non-condensable gas is mounted in an opening part of the steam drawing pipeline located inside the dry well in the nuclear reactor containment vessel. The non-condensable gas separation filter includes, at an upstream side thereof, an aerosol collector.SELECTED DRAWING: Figure 7 【課題】窒素や水素などの非凝縮性ガスが存在した場合でも静的原子炉格納容器冷却設備の除熱性能の低下を、動力などを用いず静的な力のみで抑制可能なこと。【解決手段】原子炉格納容器の外部に設置された熱交換器と、一端が前記熱交換器に接続され、他端が前記原子炉格納容器内のドライウェルの内部に位置し、前記ドライウェル内の蒸気を前記熱交換器に引き込む蒸気引き込み配管と、前記熱交換器から前記原子炉格納容器内のサプレッションプールに繋がる凝縮水排出管と、内部に冷却水が満たされ、前記熱交換器が収納配置されている蒸気冷却プールとを備えた静的原子炉格納容器除熱系において、前記原子炉格納容器内のドライウェルの内部に位置する前記蒸気引き込み配管の開口部に、蒸気と非凝縮性ガスを分離する非凝縮性ガス分離フィルタが設置され、前記非凝縮性ガス分離フィルタは、その上流部にエアロゾル捕集装置を備えていること。【選択図】図７
