And sealing materials (not shown) are also arranged on both end surfaces of the hollow member 42.

When the shape of the cross section is a non-circle such as a quadrangle or a triangle, the corner of the cross section is usually provided with roundness for the purpose of preventing cracks. This rounded portion is referred to as an “R” portion in this specification. 5 and 6, 51 and 61 are hollow portions, 52 and 62 are hollow members, 53
Reference numerals 56 to 63 to 66 denote sealing materials, and 57 to 60 and 67 to 69 denote R portions.

ある。In the case where the cross section of the hollow member is non-circular as described above, at the time of joining, the hollow members are densely arranged with the side surfaces of the hollow members in contact with each other. In a load environment subject to such a high heat load, internal pressure load, asymmetric electromagnetic force load, and the like, a bending load and a peak load may be concentrated on the R portion of the hollow member and its vicinity.

If the stress concentration increases and the R radius is too large, the stress concentration decreases, but the local stiffness of the R portion increases, resulting in an increase in thermal stress. Therefore, it is necessary to perform a selection operation for determining the radius of curvature of the R portion based on empirical advanced technical judgment corresponding to the design load.

And peak loads are concentrated. In the case of a non-circular hollow member, the magnitude of the bending radius of the corner R portion is slightly affected by the thermal load environment. If the R radius is too small, the stress concentration increases, and if the R radius is too large, Although the stress concentration is reduced, the local stiffness of the R portion is increased, so that the thermal stress is increased.

Not much to do.
Higher reliability can be maintained by installing the cooling pipe, which is a pressure-resistant boundary, at the interface of the same type of material, which is more reliable, than at the interface between different materials of stainless steel and copper (Cu). .

置する方が、設計信頼性が高まる。In other words, when a shear load or a bending load due to a large electromagnetic force causes cracks at the interface of hot isostatic pressing (hereinafter sometimes simply referred to as HIP), the thermal expansion coefficient differs. The thermal stress is superimposed on the dissimilar material interface, so that the damage is expected to be the largest. Therefore, the design reliability is higher when it is installed at the interface of the same kind of material than at the different kind of material.

In short, it is only necessary to have the minimum number of tubes required in the design, and it is not necessary to install them in close contact with each other.If the hollow members for cooling are arranged separately as in the present invention, By reducing the HIP interface density, there is an effect that design reliability is relatively increased.

Ｐの成功率を高め得るという効果を奏する。(4) Effect of Providing Groove Processing (Hollow Member Fitting Portion) in Plate-shaped Member In HIP joining, it is required to eliminate as much as possible a gap between the contacting members during assembly. . Therefore, at the time of assembling the block before HIP, the plate member is subjected to groove processing in advance so that the outer peripheral portion of the hollow member is in close contact with the plate member. As a result, the finished dimensional accuracy and HI
This has the effect of increasing the success rate of P.
