摘要： PROBLEM TO BE SOLVED: To set a floor buried article under a steel plate concrete floor without enlarging the joist size of the steel plate concrete even if the distance between facing walls is large in a nuclear power plant building.
SOLUTION: The steel plate concrete floor 12 is supported by a steel beam 13, and the steel beam 13 is burdened with placing pressure required for the joist 4, to thereby lower the height of the joist 4, and to secure a setting space for the floor buried article.

摘要： PROBLEM TO BE SOLVED: To carry out or carry in a reactor pressure vessel without providing a temporary opening on the roof of a reactor building, or without installing a large-scale crane in the outdoors of the reactor building.
SOLUTION: This reactor pressure vessel carrying-out method has processes of: providing a temporary opening 6 on the side wall on a fuel operation floor of the reactor building 18; and carrying out the reactor pressure vessel 1 through the temporary opening 6. The method also has a process of installing a jack bridge 7 in the outdoors of the reactor building, and a lowering process of lowering the reactor pressure vessel 1 carried out from the temporary opening 6 onto the ground in the laid-down state by the jack bridge 7. The method also has processes of: hoisting the reactor pressure vessel 1 in an apparatus temporary placing pool 11 inside the reactor building 18 in the inclined or laid-down state onto the fuel operation floor before carrying out the reactor pressure vessel 1 through the temporary opening 6; and conveying the reactor pressure vessel 1 lowered onto the ground by the jack bridge 7 in the laid-down state as it is to a storage warehouse near the reactor building 18.

摘要： PROBLEM TO BE SOLVED: To take a safety measure against such a trouble that a crane may be fallen down when vibration is applied from the outside thereto by earthquake or the like when large equipment is carried in and out of a building by using a carrying crane in a nuclear power plant.
SOLUTION: A crane 1 for carrying the equipment is installed on a crane foundation 20 having base isolation function, and the equipment 3 is carried out of and carried in a carried-out/carried-in position by using the crane for carrying the equipment. The crane foundation 20 is formed by installing a base isolation device such as a laminated rubber 8 on an improved ground 7 and installing a crane installation plate 2 on which the crane 1 is fixed on the base isolation device. The crane installation plate 2 can be fixed, as necessary, to the improved ground 7 by a horizontal fixing device 10.
