BLOWOUT DEVICE
To reduce burden on a chain due to inertial force in an opening/closing direction of a closing door in an earthquake.SOLUTION: In order to solve the above problem, a blowout device of the present invention comprises; a closing panel that is provided at openings 20A3, 20A4 of a reactor building, and opens when the internal pressure of the reactor building exceeds a predetermined value; guide rails provided above and below the closing panel; a closing door slidably installed along the guide rail so as to cover the closing panel; support members 20A1, 20A2 that suppress the movement of the closing door in an opening/closing direction based on the shaking during an earthquake; and driving means of driving the support members in an out-of-plane direction of the closing door.SELECTED DRAWING: Figure 5
【課題】地震時における閉止扉の開閉方向の慣性力によるチェーンへの負荷を低減すること。【解決手段】本発明のブローアウト装置は、上記課題を解決するために、原子炉建屋の開口部２０Ａ３，２０Ａ４に前記原子炉建屋の内部圧力が所定値以上になったときに開放する閉止パネルと、該閉止パネルの上下に設けられたガイドレールと、前記閉止パネルを覆うように、前記ガイドレールに沿ってスライド可能に設置された閉止扉と、地震時の揺れに基づいて前記閉止扉の開閉方向への移動を抑制する支持部材２０Ａ１，２０Ａ２と、該支持部材を前記閉止扉の面外方向に駆動する駆動手段とを備えていることを特徴とする。【選択図】図５
