Abstract

PURPOSE:To enhance the mechanical reliability of armor mounting plug bolts by holding an armor tile with a supporting sleeve and using the armor mounting bolts as plug bolts to prevent pull-off of the supporting sleeve. CONSTITUTION:The bend and torsional force generated in the armor tile 4 when load such as impulsive electromagnetic force or the like is exerted thereon at the time of plasma annihilation are transmitted from a flange 9a in the upper part of the supporting sleeve 9 via a cylindrical part 9b of the supporting sleeve to a latch 11 at the front end of the supporting sleeve. This load is supported by a latch 11 and a circumferential groove 15 of the inside surface of the armor mounting seat fitted to the latch 11. The slit formed in the lower half part of the supporting sleeve decreases the radial bending rigidity of the sleeve 9 and facilitates insertion of the latch 11 part of the sleeve into the groove 15. The plug bolts are, therefore, inserted and set to the inner side of the supporting sleeve in order to prevent relieving of the angle of the latch 11 part and generation of the radial bending deformation of the supporting sleeve 9. The inner peripheral face of the latch 11 is thus retained by the plug bolts 12b, by which the deformation is suppressed.

For this reason, the first wall is generally constructed using a high melting point, low atomic number material such as graphite or a ceramic material! In addition, the armor tiles on the first wall are subjected to high thermal loads, high particle loads, and electromagnetic force when the plasma disappears due to radiation from the plasma and the incidence of ions, electrons, and neutral particles. Armor tiles can become damaged or worn and need to be replaced. Considering the activation inside the reactor by plasma operation, it is desired that the first wall has a mechanical connection structure that can be replaced by remote control.

Since they are generally brittle materials, there is a high possibility that these components will be damaged when subjected to thermal shock or shock electromagnetic force during plasma extinction.Especially when electromagnetic force is applied, the mounting bolts may be bent or torsionally loaded. As a result, the bolt threads may be damaged or galled, making it impossible to replace the armor tile during overhaul by remote control, or making it impossible to install a new armor tile, resulting in a major hindrance to the operation of the fusion device. cause

This is because the armor tile is directly fixed to the armor mounting seat with the armor mounting bolt, so the load applied to the armor tile is directly transmitted to the armor mounting bolt. That is, the bending torsional load such as electromagnetic force generated on the armor tile is directly applied to the threaded portion of the armor mounting bolt, which poses a major problem in terms of structural strength, such as damage or galling of the threaded portion.
