るベースである。 An overview of the torus-type fusion device will be explained with reference to FIGS. 1 and 2. As shown in the figure, the torus-type nuclear fusion device is constructed by alternately arranging thick-walled parts 2a and bellows parts 2b, and evacuates the inside to generate plasma 1.
a vacuum vessel 2 that holds a plasma 1; a plurality of toroidal coils 5 that surround the vacuum vessel 2 and are arranged at predetermined intervals in the circumferential direction of the torus in order to generate a toroidal magnetic field that is the core of the plasma 1; It is generally composed of a poloidal coil 6 arranged concentrically along the vacuum vessel 2 to generate and control. Note that 7 is a current transformer coil, 8 is a vacuum exhaust device, and 9 is a base that supports the toroidal coil 5.

にしている。 In the poloidal coil 6 in the torus-type nuclear fusion device configured as described above, a main radial electromagnetic force 13 and a vertical electromagnetic force 12 are generated by the action of the poloidal coils 6 together, as shown in FIG. The former receives electromagnetic force by the conductor itself, and the latter receives the electromagnetic force by the conductor itself, and the latter receives the coil support 10 that supports the poloidal coil 6.
supports electromagnetic force. Therefore, a hoop stress due to the main radial electromagnetic force 13 and a bending stress determined by the vertical electromagnetic force 12 and the coil support span are generated in the conductor. The coil supports 10 are arranged evenly around the entire circumference of the torus, but the outer circumferential coil has a longer support span and the bending stress increases. Therefore, as shown in FIG. 3, the outer coil support section has a coil support shelf 11 extending in the toroidal direction to shorten the coil support span and thereby reduce the bending stress.

きな歪が発生し、絶縁が破壊される恐れがある。 However, in addition to the electromagnetic force generated by the poloidal magnetic field, an electromagnetic force is generated in the outer circumferential coil due to the ripples of the toroidal magnetic field. This electromagnetic force is generated because the toroidal coil 5 is made up of a finite number of coils, but as shown in FIG. However, this occurs because the magnetic field leaks from the toroidal coil 5 on the outer circumferential side of the torus, and the strength of the toroidal magnetic field changes in the toroidal direction. Due to this toroidal magnetic field ripple, a toroidal magnetic field ripple electromagnetic force 15 as shown in FIG. 5 is generated in the poloidal coil 6. This toroidal magnetic field ripple electromagnetic force 15 acts on the coil support shelf 11 protruding from the coil support 10, and acts on the coil support 10 to bend it out of plane. This bending moment causes the coil support 1 to
If 0 is deformed out of plane, a large strain will occur in the poloidal coil 6, and there is a possibility that the insulation will be broken.

常に効率的である。 The shear panel 16 of this embodiment eliminates relative displacement between the coil support shelves 11, cancels the moment that causes out-of-plane deformation of the coil support 10, and suppresses out-of-plane deformation. Therefore, no distortion occurs in the poloidal coil 6, and there is no fear of dielectric breakdown, so the integrity of the coil can be guaranteed. Furthermore, by insulating the center of the shear panel 16, it is possible to prevent eddy currents from flowing in the circumferential direction of the torus. Moreover, combining the coil support shelves 11 makes effective use of space, and for example, in a nuclear fusion device that needs to share space with a neutral particle heating injection port, a measurement port, etc. attached to the nuclear fusion device. is very efficient.
