摘要： If a molten core holding apparatus (core catcher) is disposed below a reactor pressure vessel in a reactor containment vessel, water leak cannot be detected at a pedestal floor. Thus the reactor containment vessel has to be separately equipped with a mechanism for detecting the water leak. A water leak detection floor (11) transversally suspended by a pedestal side wall (22) is installed between a reactor pressure vessel (1) and a molten core holding apparatus (10). If a water leak occurs at the reactor pressure vessel (1), the water leak detection floor receives and detects the leak water. In a core meltdown accident, corium melts and penetrates the water leak detection floor and deposits on the molten core holding apparatus.

摘要翻译： 如果在反应堆安全壳的反应堆压力容器的下方设置熔融铁心保持装置（铁心捕捉器），则不能在台座底部检测到漏水。 因此，反应堆安全壳必须单独配备检测漏水的机构。 在反应堆压力容器（1）和熔融铁芯保持装置（10）之间安装有由底座侧壁（22）横向悬挂的漏水检测底板（11）。 如果在反应堆压力容器（1）处发生漏水，则漏水检测层接收并检测到泄漏水。 在核心熔毁事故中，真皮熔化并渗入漏水检测层并沉积在熔化的夹芯设备上。

摘要： There is provided a pressure suppression apparatus for a nuclear power plant. The pressure suppression apparatus includes a reactor vessel, reactor container, drywell cooler, and a first fan. The reactor vessel stores nuclear fuels for electric power generation. The reactor container stores the reactor vessel and defines drywell rooms. The drywell cooler cools air in the drywell rooms so as to suppress pressure in the drywell rooms. The first fan guides air in the drywell rooms into the drywell cooler. The pressure suppression apparatus of the present invention further includes a second fan for exhausting non-condensable gas among air from the drywell cooler. The second fan is operated by an emergency power supply, and therefore the second fan can continue to exhaust non-condensable gas if the first fan stops.
