摘要： A container-outer-periphery pool in which water is stored is provided between a primary containment vessel and a reactor building, and outside of a pressure suppression pool. Consequently, the natural heat transfer capabilities of reactor facilities is enhanced, and the inherent safety of the reactor facilities is improved.

摘要： A natural circulation reactor includes a reactor pressure vessel, a cylindrical shroud disposed within the reactor pressure vessel to surround a reactor core and to extend to a position above the reactor core, and a coolant descending passage defined between the reactor pressure vessel and the shroud for allowing the coolant discharged from the top of the reactor core to be again supplied to the bottom of the reactor core. In such a natural circulation reactor, a liquid level of coolant in the coolant descending passage is adjusted on the basis of a reactor power request signal at a position below a liquid level of coolant in the shroud, and thus reactor power is controlled so that it may reach a predetermined reactor power by adjusting the liquid level of coolant in the coolant descending passage.
摘要翻译：自然循环反应器包括反应堆压力容器，设置在反应堆压力容器内以围绕反应堆堆芯并延伸到反应堆堆芯上方位置的圆柱形护罩，以及在反应堆压力容器和护罩之间限定的冷却剂下降通道，允许将从反应堆堆芯顶部排出的冷却剂再次供应到反应堆堆芯的底部。在这样的自然循环反应器中，根据在护罩中的冷却剂液面以下的位置的反应堆功率要求信号来调节冷却剂下降通道中的冷却剂液面，从而控制反应堆功率可以通过调节冷却剂下降通道中的冷却剂的液位来达到预定的反应堆功率。

摘要： The nuclear reactor container of a boiling water reactor has a dry well and a pressure suppression chamber. The level of the radioactivity in the cooling water filling the pressure suppression chamber is measured by a liquid radiation monitor. An iodine monitor measures a level of the radioactivity of the iodine in the space above the surface of cooling water in the pressure suppression chamber, while a noble gas monitor measures a level of the radioactivity of noble gas in the same space. Outputs from the liquid radiation monitor, the iodine monitor and the noble gas monitor are delivered to an accident judging device which makes judgement as to occurrence of perforation of fuel rods and melt down of fuel rods in the event of a Loss Of Coolant Accident (LOCA), the result of which is displayed at a display device.
