  • Publication number: 20050135538
    Abstract: A structure in a reactor building to be transported is made small when the structure is carried out from the reactor building and/or when the structure is carried into the reactor building. A beam is used outside a building inside of which a reactor pressure vessel is installed. The beam passes above the reactor pressure vessel and crosses over the building. A lifting machine has a lifting device and is moved on the beam. A shield is provided for shielding radioactive rays radiated from the reactor pressure vessel into the building through an opening portion provided in a roof of the building. The reactor pressure vessel, is moved together with the shield upward through the opening portion using the lifting device.
