Claims (1)
注水タンクにおいて、注水タンク内に案内部材を
昇降可能に設けて、同案内部材に浮子を固定し、
同浮子の内部を同浮子の上部に設けた導通管を介
して注水タンク内の加圧空間部に連通し、同浮子
が下限位置まで下降したときに注水タンク内の冷
却水を小流量で流出させる小流量流出路を同浮子
の下部と注水タンクの出口側底部との間に形成し
たことを特徴とする非常用冷却水の注水タンク。 In an emergency cooling water injection tank whose bottom part communicates with the reactor cooling system, a guide member is provided in the water injection tank so as to be movable up and down, and a float is fixed to the guide member,
The inside of the float is communicated with the pressurized space in the water injection tank via a conduction pipe installed at the top of the float, and when the float descends to the lower limit position, the cooling water in the water injection tank flows out at a small flow rate. A water injection tank for emergency cooling water, characterized in that a small flow outflow path is formed between the lower part of the float and the bottom of the outlet side of the water injection tank.
