を特徴とする原子炉格納容器。 A lower dry well is formed within the reactor pedestal whose periphery is covered by the containment vessel body, and the space around the reactor pedestal is divided into upper and lower sections by a diaphragm floor that crosses within the containment vessel body. , in a nuclear reactor containment vessel of the type in which an upper dry well and a suppression chamber are formed, an access passage for entering and exiting the lower dry well extends from the upper dry well through the diaphragm floor to the lower dry well. It is characterized by being composed of a vertical passageway that descends to a position corresponding to the dry well and is vertically attached to the reactor pedestal, and a communication passageway that connects the lower end of the vertical passageway to the interior of the reactor pedestal. Reactor containment vessel.
