Abstract
When carrying the large structure out through an aperture portion provided at a roof of a reactor building, a chamber for covering the aperture is provided at the roof so that work of providing the chamber for covering the aperture portion can be performed independent of other work performed in the reactor building, before at least a part of work of using a roof crane and at least a part work of handling fuel assemblies in the reactor building.
Claims18
A method of handling a large structure in a reactor building for carrying said large structure out through an aperture portion provided at a roof of said reactor building, wherein
- an isolation chamber is provided to said roof of said reactor building at a position between said roof of said reactor building and traveling path of an overhead traveling crane in said reactor building,
- an aperture portion is formed at a location directly above said isolation chamber of said roof of said reactor building, and
- said large structure in said reactor building is carried out through doors of said isolation chamber and said aperture portion of roof of said reactor building.
A method of handling a large structure to be installed in a reactor building for carrying said large structure into said reactor building through an aperture portion provided at a roof of said reactor building, wherein
- an isolation chamber is provided to said roof of said reactor building at a position between said roof of said reactor building and traveling path of an overhead traveling crane in said reactor building,
- an aperture portion is formed at a location directly above said isolation chamber of said roof of said reactor building, and
- said large structure to be installed in said reactor building is carried in through doors of said isolation chamber and said aperture portion of said roof of said reactor building.
A method of handling a large structure in a reactor building for carrying said large structure out through an aperture portion provided at a roof of said reactor building, wherein
- said large structure in said reactor building is carried out through doors of an isolation chamber which is provided to said roof of said reactor building at a position between said roof of said reactor building and a traveling path of an overhead traveling crane in said reactor building, and through an aperture portion which is formed at said roof of said reactor building.
A method of handling a large structure to be installed in a reactor building for carrying said large structure into said reactor building through an aperture portion provided at a roof of said reactor building, wherein
