Description
【発明の詳細な説明】 ［発明の目的］ （産業上の利用分野） 本発明はプラズマを生成する核融合装置における真空
容器の支持装置を改良したものである。DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention is an improved support device for a vacuum vessel in a nuclear fusion device for generating plasma.
（従来の技術） プラズマを生成する核融合装置における真空容器にお

な電磁力を発生する。この電磁力は核融合装置の半径方
向成分と核融合装置の装置中心軸（垂直）方向成分に分
解することができる。(Prior art) In a vacuum vessel of a nuclear fusion device for generating plasma, when the plasma generated inside disappears rapidly, a large eddy current flows in the vacuum vessel, and this eddy current confines the plasma or generates the plasma. Electromagnetic interference with an external magnetic field for controlling confinement generates a very large electromagnetic force in the vacuum vessel. This electromagnetic force can be decomposed into a radial component of the fusion device and a component central (vertical) component of the fusion device.
ところで、このような電磁力が作用するプラズマ真空
容器において、電磁力の半径方向成分に対しては真空容
器自身で耐え得る支持構造とすることが可能であるが、
電磁力の垂直方向の成分に対して真空容器を支持するた
めには外部に特別に支持体を設ける必要がある。また、
電磁力の半径方向成分は主に真空容器のトロイダル方向
に流れる渦電流に起因するため、これを小さくするため
には真空容器のトロイダル方向の電気抵抗を大きくする
必要がある。By the way, in a plasma vacuum vessel in which such an electromagnetic force acts, it is possible to use a support structure that can withstand the radial component of the electromagnetic force by the vacuum vessel itself.
In order to support the vacuum container against the vertical component of the electromagnetic force, it is necessary to provide a special support outside. Also,
Since the radial component of the electromagnetic force is mainly caused by an eddy current flowing in the toroidal direction of the vacuum vessel, it is necessary to increase the electrical resistance of the vacuum vessel in the toroidal direction in order to reduce the eddy current.
これらの観点から核融合装置における真空容器として
は薄肉シェル構造の真空容器がよく使用されており、特
に大型の核融合装置にあっては重量軽減等の点からも有
利である。From these viewpoints, a vacuum container having a thin shell structure is often used as a vacuum container in a nuclear fusion device, and is particularly advantageous in terms of weight reduction in a large-scale fusion device.

い。On the other hand, it is necessary to realize a high vacuum state in order to generate plasma inside the vacuum vessel, and therefore, the vacuum vessel is generally baked. In this case, the vacuum container thermally expands by baking, but this thermal expansion cannot be restrained from the viewpoint of the material strength of the vacuum container.
そこで、従来ではこのような熱膨脹を逃がし、かつ前

がある。Therefore, conventionally, a trunnion supporting system as shown in FIGS. 4 to 6 has been used as a supporting device for releasing such thermal expansion and supporting the vacuum vessel against the above-mentioned electromagnetic force.

It is arrow sectional drawing which follows the VI line. 4 to 6, reference numeral 1 denotes a toroidal vacuum vessel, in which a plasma 2 is generated. Reference numeral 3 denotes an external support frame provided with an appropriate gap so as to cover the outer peripheral portion of the vacuum vessel 1. The external support frame 3 is provided with a poloidal coil 4.
An external support frame-side trunnion bearing 7 formed of a spherical bearing body 5 and an eccentric ring 6 provided inside the through-hole formed on the outside of the external support frame 3 and extending toward the vacuum vessel.

A trunnion shaft 9 is inserted between the two bearings 7 and 8 to support the trunnion. The vacuum vessel 1 is supported by constituting a supporting device according to the method. In this case, the trunnion shaft 9 is provided with a pair of trunnion bearings 7 from the side of the external support frame 3.
After the trunnion shaft 9 is set in the center of the trunnion shaft 9 by the eccentric ring 6, the trunnion shaft 9, the eccentric ring 6 and the spherical bearing 5 are integrally attached at the welded portion 10.

持される。In the support device having such a configuration, since the trunnion shaft 9 can slide in the axial direction with respect to the vacuum vessel side trunnion bearing 8, even if the vacuum vessel 1 is thermally expanded by baking, its thermal deformation is reduced by the trunnion support portion. Is absorbed by. The vertical component of the electromagnetic force acting on the vacuum vessel 1 is transmitted to the external support frame 3 via the trunnion shaft 9 and is supported.

Therefore, not only is it easy to assemble the trunnion support portion, but also there is no restriction on the installation location. Thereby, the trunnion support portion can be provided near the center surface of the vacuum vessel on the inboard side of the vacuum vessel, so that the plasma generated in the vacuum vessel moves and disappears, and the electromagnetic force on the inboard side of the vacuum vessel increases. Even after that, sufficient structural strength of the vacuum vessel can be secured,
It will be highly reliable. In addition, by supporting the inboard side of the vacuum vessel, the natural frequency of the vacuum vessel can be increased, which is not only advantageous for earthquake resistance, but also reduces the average shear force of the trunnion shaft and the average surface pressure of the bearing spherical surface. can do.

Furthermore,
Since the external support frame is provided with a spherical bearing around the trunnion axis and an electrical insulator inserted inside the spherical bearing, the vacuum vessel and the external support frame are not electrically connected to each other. Also, there is no current path that is inconvenient for controlling the plasma.

That is, the inboard side and the outboard side near the center plane of the vacuum vessel 1 are provided with holes penetrating the inside and outside of the vessel, and the eccentric ring 22 and the spherical bearing body provided on the outer periphery thereof are provided in these holes.
A vacuum vessel side trunnion bearing 20 constituted by 21 is inserted. The external support frame 3 is also provided with a hole at a position corresponding to the hole on the vacuum vessel 1 side, and a block 24 having a through hole in which a cooling pipe 23 is embedded is fitted into this hole. An external support frame side trunnion bearing composed of a concentric cylinder 26 in a through hole of a body 24 and a spherical bearing body 28 provided through a mold insulating layer 27 formed on the outer peripheral surface thereof.

とができる。In the vacuum vessel support device having such a configuration, the concentric cylinder 26 is disposed on the inner peripheral side of the spherical bearing body 28 of the external support frame side trunnion bearing 25 via the mold insulating layer 27. Since the vacuum vessel 1 and the external support frame 3 are electrically disconnected from each other, it is possible to cut off an undesired current path in terms of plasma operation and the strength of the vacuum vessel 1. The trunnion shaft 29 is connected to the vacuum vessel side trunnion bearing 20 and the external support frame side trunnion bearing 25 from inside the vacuum vessel 1.
And the support structure for supporting the vacuum vessel 1 on the external support frame 3 not only facilitates its assembly, but also does not limit the installation location of the support structure. Therefore, the vacuum vessel 1 can be provided not only on the outboard side near the center plane of the vacuum vessel 1 but also on the inboard side, so that even when the plasma moves and disappears and the electromagnetic force on the vacuum vessel side on the inboard side is large, the vacuum vessel 1 Can be supported soundly. By supporting the inboard side of the vacuum vessel 1, the natural frequency of the vacuum vessel 1 can be increased,
Not only is it advantageous in terms of seismic resistance, but also the average shear stress of the trunnion shaft 29 and the average surface pressure of the spherical bearing bodies 21 and 28 can be reduced, and the reliability of the support structure can be improved.

ない。On the other hand, when the vacuum vessel 1 is baked, heat is transmitted to the external support frame 3 via the trunnion shaft 29 and the external support frame-side trunnion bearing 25, and the heat thus transmitted is cooled by the cooling unit embedded in the block body 24. Since it is removed at the pipe 23,
The poloidal coil 4 is not damaged by the baking of the vacuum vessel 1. Further, since the trunnion shaft 29TiN is coated, there is no possibility that the trunnion shaft 29 will be galled at its sliding portion. In addition, trunnion shaft
Since the tube 29 is integrated with the trunnion bearing 20 by welding from the inside of the vacuum vessel 1, even if the vacuum vessel 1 is excessively deformed, the lid 31 is not broken by the trunnion shaft 29.
