並べて配置されている。That is, a containment vessel 2, which houses therein a reactor vessel 1 surrounding a reactor core provided with fuel assemblies, communicates with a storage chamber 3 at its side. A storage room track 4 is provided in the storage room 3, and this track 4 is connected to a containment vessel track 5, and a fuel transfer machine 6 runs on these tracks 4 and 5. Below the track 4 in the storage room, a fuel storage tank 7, a fuel inspection tank 8, and a fuel transfer tank 9 are arranged in a straight line along the track. When transferring nuclear fuel into and out of the reactor during fuel exchange, inspecting it, storing it, etc. as necessary, the fuel transfer device 6 is used to raise and lower the fuel assembly, and also to move it horizontally. Fuel assemblies are taken in and out of various tanks 7 to 9 in the reactor vessel 1 and storage room 3. A conventional fuel transfer system is constructed as described above, and includes various tanks 7 necessary for handling nuclear fuel.
9 to 9 are arranged in a straight line along the storage room track 4 and immediately below it.

In addition, in order to take fuel in and out through the storage chamber 3, the track extending through the fuel inlet/outlet provided in the wall surrounding the storage chamber 3 must be extended. Furthermore, if a track extending to the outside is provided, for example, in a direction perpendicular to the track within the containment vessel, it is necessary to separately install the external track and provide another fuel transfer device. In such a case, the structure of the fuel transfer system becomes more complicated, the reactor auxiliary building including the storage room becomes larger, and the work becomes more complicated and time-consuming. Therefore, an object of the present invention is to have a simple structure, to be able to transfer fuel in multiple directions using one fuel transfer device, to be able to carry out fuel loading and unloading easily and quickly, and to be able to use a reactor auxiliary building. An object of the present invention is to provide a fuel transfer system for a nuclear reactor that is downsized.

That is, it is placed in a position aligned with the connecting track 13, the transfer machine 6 is moved on the track and moved onto the fuel storage tank 7, and the fuel assembly is lowered into the fuel storage tank 7. When transferring the fuel assembly hoisted by the transfer device 6 to a desired facility such as the fuel transfer tank 9 or the fuel inspection tank 8, the storage indoor track 11, which is a rotating track, is rotated and arranged on the circumference. The transfer machine 6 is moved above the various tanks, and the fuel assembly is lowered at that position. In addition, if the rotary orbit 11 is rotated while the transfer machine 6 is placed on the rotary orbit 11 and aligned with the external orbit 15, the transfer machine 6 will run on the external orbit 15 and move to the outside of the reactor facility, etc. may be transported to a location.
