The installation height of the rails 7 and 8 is one of the factors that determine the height of the upper dry well 91 of the reactor containment vessel 2, and also the upper dry well 91.
The height is a factor that determines the volume of the dry well 91. Since the volume of the wet well 92 and the volume of the dry well 91 are made substantially the same in order to absorb the pressure during the initial blowdown, the volume of the dry well 91
The height of the reactor containment vessel 2 is determined.

Further, when the height of the reactor containment vessel 2 is determined, the height of the reactor building 93 is also determined. As a result, depending on the case, the quantity of the reactor building 93 is affected if the floor is changed, and the construction period of the reactor building 93 is also affected. The reduction of the construction period has a great effect on cost reduction such as reduction of interest during construction. That is, the rail 7
The installation heights of 8 and 8 are important dimensions that determine the height of the reactor containment vessel 2 and are factors that determine the construction period and the construction cost.

Incidentally, as a device relating to the loading and unloading facility of the valve in the reactor containment vessel of this type, for example, Japanese Patent Laid-Open No.
5795 or Japanese Patent Laid-Open No. 59-159096.

A first moving route comprising a transportation facility for suspending and arranging valves arranged side by side around a reactor pressure vessel, and the transportation facility travels above the valves in the arranging direction of the valves. And a second moving route provided in parallel with the first moving route, and the valve of the reactor containment vessel in which the valve is hung up and carried out of the reactor containment vessel by this transportation facility is carried out. In a facility for carrying out or carrying in, a reactor containment vessel characterized in that between the first moving route and the second moving route, a transporting facility that moves across both moving routes or hangs is installed. Equipment for unloading or importing inner valves. 10. A transportation facility for suspending and transporting valves, which are arranged in parallel in a concentric manner in a double arrangement around a reactor pressure vessel,
This transportation facility has an outer movement route and an inner movement route that respectively travel in the upper part of the valve in the direction in which the valves are arranged in parallel, and the transportation facility suspends the valve and carries it out of the reactor containment vessel. In a facility for carrying out or carrying in a valve in the reactor containment vessel designed to be carried in into the reactor containment vessel, between the outer movement route and the inner movement route, straddling or hanging between both movement routes. A facility for carrying out or carrying in a valve in a nuclear reactor containment vessel, characterized in that a transport facility for moving the valve is installed, and the valve is configured to be transportable in a direction perpendicular to the moving route. 11. A route for connecting the rail on the inner moving route to a position inside the route connecting the inner valve setting points, and a route for connecting the outer rail setting on the outer moving route on the outer valve setting point. The equipment for carrying out or carrying in the valve in the reactor containment vessel according to claim 10, which is located outside of the above. 12. A transport facility for suspending a main steam relief safety valve, which is concentrically arranged in parallel around the reactor pressure vessel, and which carries the main steam relief safety valve, wherein each of the transport facilities has an upper portion of the main steam relief safety valve. It has an outer movement route that runs in the direction in which the valves are installed in parallel, and an inner movement route.This transportation facility carries the main steam relief safety valve and carries it out of the reactor containment vessel or into the reactor containment vessel. In the facility for carrying out or carrying in the valve in the reactor containment vessel, the intermediate rail is installed between the rail of the inner moving route and the rail of the outer moving route, and the intermediate rail and the main steam are installed. Install a branch rail between the relief safety valves, between the outer rail and the inner main steam relief safety valve, or between the inner rail and the outer main steam relief safety valve. Unloading or loading to equipment of the formed that the containment vessel valve, wherein like.
