摘要： PROBLEM TO BE SOLVED: To provide a first wall and a divertor plate which are installed so that the wall and divertor can be faced oppositely to the plasma of a nuclear fusion device and has a high thermal shock resistance. SOLUTION: A carbon fiber-reinforced composite carbon material is integrally constituted by laminating a unidirectional carbon fiber-reinforced material and tri-directional carbon fiber-reinforced material upon another in the thickness direction so that the carbon fibers substantially oriented in the thickness direction can become continuous in the thickness direction. A first wall and a divertor plate are positions adjacently to the unidirectional carbon fiber- reinforced section so that the wall and plate can be faced to the plasma of a nuclear fusion device constituted mainly of the carbon fiber-reinforced composite carbon material in which a metal is joined to one surface of the unidirectional carbon fiber-reinforced section substantially perpendicular to the thickness direction of the section or a metallic tube is buried in the tri-directional carbon fiber-reinforced composite carbon material.

摘要： PURPOSE:To provide a high heat flux heat receiving plate excellent in manufacturing property which is highly safe to resisting stress breakage and burnout. CONSTITUTION:A cooling pipe 2 is brazed to a heat resisting heat receiving material 1 vertically through its base bottom part. The heat receiving material 1 is formed of a composite material the matrix phase of which is reinforced by a fibrous filler having high heat conductivity in fiber axial direction. The filler fiber is oriented, on both side end areas of the heat receiving material 1, in the orthogonal direction to the heat receiving surface near the heat receiving surface and in the direction of the water cooling pipe near the water cooling pipe 2. On the other hand, in the just above area of the water cooling pipe 2, the orientation in the orthogonal direction to the heat receiving surface of the fibrous filler is set low, compared with both the side end areas, and the heat conductivity is set low, compared with the side end areas. Consequently, the parallelism to the heat receiving surface of the equilibrium temperature distribution in the heat receiving member can be enhanced.

摘要： PURPOSE:To provide a diverter for a nuclear fusion device which is equipped with a diverte plate supporting structure sustaining an electromagnetic force and absorbing thermal strain in the diverter heat-reception part. CONSTITUTION:When a diverter plate 1 and a cooling pipe 6a undergo thermal deformation in the X-direction, the generated thermal strain is absorbed by parallel movement along groove 16 of a curved leaf spring 3, that in the Y- direction absorbed by Y-directed elongations/contractions of a flat plate spring 4 and the curved leaf spring 3, and that in the Z-direction absorbed by Z-directed elongation/contraction of the leaf spring 3. Thus it is possible to absorb thermal strain generated in any direction in the diverter plate. Accordingly the established supporting structure can absorb a three-dimensional thermal deformation strain in the diverter plate 1 and the heat reception part such as cooling pipe 6a, and the impurity control is stabilized even during long-time operation of the device, and a high reliability diverter can be built which can sustain the electromagnetic force at the time of plasma disruption.

CONSTITUTION:A control object value is input to a control object input member 1. Then, the first prepro-data to operate a neutral particle incident unit NBI at an ideal condition is produced by using the first prepro-data producing member 2. Then, the produced first prepro-data is output to the unit NBI by the first prepro-data output member 3, and its response is picked up in the first prepro-data monitor 4. After that, by using the said response, the second prepro- data is produced by using the second prepro-data producing member 5. Then, it is decided by an examination result deciding member 6 whether the second prepro-data is satisfactory or not. When it is not satisfactory, it is corrected by using a prepro-data correction member 7, and then a test operation is repeated. And when a satisfactory result is obtained, the role of the device is completed.
