Description
ところで、原子炉格納容器は、万一重大事故等が発生した場合に、内部温度が上昇して、意図せぬ内圧の上昇が発生する。この場合に、原子炉格納容器の内圧は、設計圧力を上回り、限界圧力以上に上昇する可能性がある。 By the way, in the event of a serious accident or the like, the internal temperature of the reactor containment vessel rises, causing an unintended rise in internal pressure. In this case, the internal pressure of the reactor containment vessel is above the design pressure is likely to rise over the limit pressure Chikara以.
なお、定期検査では、本体部１１からトップヘッド１２が取り外され、燃料交換等の作業が行われる。 In the periodic inspection, the top head 12 is removed from the main body 11 , and work such as refueling is performed.
本実施形態では、モータ４１は、原子炉格納容器１０Ｂの外部から内部に亘って敷設された図示せぬケーブルを介して外部装置（例えば、原子力発電設備の中央制御室に設置された制御装置）との間で通信を行うものとして説明する。また、モータ４１は、そのケーブルを介して外部から供給された電力で駆動するものとして説明する。 In the present embodiment, the motor 41 is an external device (for example, a control device installed in the central control room of the nuclear power generation facility) via a cable (not shown) laid from the outside to the inside of the reactor containment vessel 10B. It is described as performing a communication with the. Further, the motor 41 will be described as being driven by electric power supplied from the outside via the cable.
同様に、本実施形態では、リミットスイッチ５１は、原子炉格納容器１０Ｂの外部から内部に亘って敷設された図示せぬケーブルを介して外部装置（例えば、原子力発電設備の中央制御室に設置された制御装置）との間で通信を行うものとして説明する。また、リミットスイッチ５１は、そのケーブルを介して外部から供給された電力で駆動するものとして説明する。 Similarly, in the present embodiment, the limit switch 51 is installed in an external device (for example, a central control room of a nuclear power generation facility) via a cable (not shown) laid from the outside to the inside of the reactor containment vessel 10B. be described as performing a communication between the control unit) has. Further, the limit switch 51 will be described as being driven by electric power supplied from the outside via the cable.
