As shown in Figures 4 and 5, the fast breeder reactor is
A rotating plug 4 is provided at the upper part of the reactor, and a reactor core upper mechanism 10 such as a control rod drive device and instrumentation lead wires is attached to the rotating plug 4, and control cables 8 and others are connected to their upper ends. When exchanging fuel rods, the cable 8 is removed from the upper end of the rotary plug 4, and while rotating the rotary plug 4, a large number of fuel rods are sequentially exchanged using a fuel exchanging machine with a pantograph arm (not shown). However, the large-diameter rotary plug 4 is surrounded by equipment 5 such as a CRD seal gas supply device and an argon gas valve stand.
is attached, and as the rotary plug 1 rotates, the device 5 also rotates. Therefore, there is a risk that the tip of the cable rack main body 1 provided close to the rotary plug 4 may come into contact with the device 5 or other protruding objects (not shown) from the outer periphery of the rotary plug. Therefore, as shown in FIGS. 4 and 5, this cable rack main body 1 has an arm about 4 m long cantilevered at the upper end of a cylindrical body 11 so as to be rotatable in a horizontal plane. In Figure 4, it is rotated as shown by the chain line.

点を有していた。 Conventionally, the end surface of the movable cable rack main body 1 was formed vertically as shown in FIG. 6, and a large number of connectors 7 were attached thereto. The reactor core upper mechanism 10 and the cable in the movable cable rack body 1 are removably connected via the connector 7 and the cable 8. However, since a large number of connectors 3 are attached to the distal end surface of the movable cable rack main body 1, it is extremely difficult to attach and detach the cable 8 using the connectors 3, and it takes a lot of time. In addition, the work of arranging the cables was troublesome, and the installation of the cable support was also troublesome. Furthermore, since the weight of the cable is applied to the connector 3 as a moment, the cable tends to come off easily.

As shown in FIGS. 2 and 3, the receptacle sides of a plurality of connectors are respectively attached to the lower surface of each staircase surface. Furthermore, a pair of guide rails 7 are provided in a cantilevered manner on the vertical wall surface of each stairway facing each receptacle, as shown in FIGS. 1 and 3.
It is protruded as shown in the figure. The guide rail 7 is configured to temporarily support the flange 12 on the plug side of the connector as shown in FIG. That is, the guide rail 7 can support the weight of the cable 8 by temporarily supporting the flange 12 of the plug 14, and aligns the plug 14 directly below the receptacle 13 by moving horizontally while supporting it in this way. can be done. Then, in this state, by lifting the plug 14 upward as shown by the arrow and screwing the two together, the connection of the connector can be easily completed. Further, this guide rail 7 is convenient for temporarily supporting the end of each cable 8 when the plug is removed.
