Reactor vessel handling method

A reactor vessel handling method comprising the steps of, in an area within a reactor containment vessel of a pressurized water reactor where an overhead traveling crane is installed, operating said overhead traveling crane to move aside for creating a space, through which a reactor vessel is able to pass;

• and
• then carrying out said reactor vessel through an opening provided in a top portion of said reactor containment vessel.

A reactor vessel handling method comprising the steps of reinforcing an overhead traveling crane in a reactor containment vessel of a pressurized water reactor, lifting a reactor vessel up to an operating floor by using the reinforced overhead traveling crane, and then carrying out said reactor vessel through an opening provided in a side wall of said reactor containment vessel.

A reactor vessel handling method comprising the steps of removing an overhead traveling crane in a reactor containment vessel of a pressurized water reactor, and carrying out a reactor vessel through an opening provided in a top portion of said reactor containment vessel;

• and
• then carrying in a new reactor vessel to a predetermined position within said reactor containment vessel through said opening.

A reactor vessel handling method comprising the steps of, in a state in which an overhead traveling crane in a reactor containment vessel of a pressurized water reactor is removed, carrying in a new reactor vessel to a predetermined position within said reactor containment vessel through an opening provided in a top portion of said reactor containment vessel.

A reactor containment vessel of a pressurized water reactor, which covers a reactor vessel and an overhead traveling crane installed above said reactor vessel,

• wherein an opening allowing said reactor vessel to be carried out through said opening is provided in at least one of a top wall and a side wall of said reactor containment vessel.
