摘要： PURPOSE: To provide a compact primary wall superior in cooling performance and capable of using in a large scale fusion device operated for long time. CONSTITUTION: On the inner surface of a vacuum vessel 2, blanket or shield body facing to plasma, corrugated plates 10, 10 having a pair of upper projections and lower dents are provided as a part 5 for fixing armor. In between the pair of upper and lower corrugated plates 10, 10, a partition plate 11 is inserted to form a going coolant path 8 and returning coolant path 9. An armor 4 is fixed to the dent part of the upper plate 10 with armor fixing bolts 7. By this, fixing the armor 4 and forming coolant paths 8 and 9 are attained without thickening the primary wall and cooling efficiency is improved because the contact area between the armor 4 and the armor fixing pat 5 is large. Further, temperature rise in the armor 4 can be suppressed low and simultaneously, thermal stress generated in the armor fixing part 5 can be reduced.

摘要： PROBLEM TO BE SOLVED: To sustain superhigh heat load and impact of neutron generated from plasma by forming a heat reception plate with armor part and heat sink part and constituting the first coated part of coating layer with titanium and copper and the second part with titanium foil. SOLUTION: The heat reception plate 17 as a wall 16 covering one sides of breeding blanket 14, diverter 15, etc., is constituted of armor part 18 of carbon group and a heat sink part 19 made of copper or copper alloy. Between the armor part 18 and the sink part 19, a coating layer 20 consisting of the first coating part 21 and the second coating part 22. The first coating part 21 is made by coating mixture powder in paste state with weight ratio of 10% titanium and 90 % copper on the armor part 18 and heated-coating in vacuum and the second coating part 22 made of titanium foil is fitted in between the coating part 21 and the sink part 19 and then heated again to form the heat reception plate 17. By this, the production of cadmium due to reaction of neutron and silver and coating force is attained. Thus, the constituting such as breeding blanket and the like is protected from superhigh heat load and neutron load.

摘要： PURPOSE: To improve shielding performance by enabling surely charging shielding pebble also in lower horizontal part of vacuum vessel in which shielding pebble is charged in a space formed by inner wall and outer wall. CONSTITUTION: In a space formed by inner wall 7 and outer wall 8 of horizontal part 1a of lower vacuum vessel, an inclined plate 12 having a multitude of penetration holes 12a wherein shielding pebble 10 can pass is provided. By this, the shielding pebbles 10 conveyed to lower part role on the inclined plate 12, fall through the penetration holes 12a and fill the space between the inner wall 7 and the outer wall 8 of horizontal part 1a.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable practical structural member for resisting plasma by improving such characteristics as the fracture toughness, thermal shock resistance, etc., of the member, wile taking note of the advantage of a ceramic material. SOLUTION: An armor (structural member for resisting plasma) 6 in the first wall of a plasma enclosing device is formed of a ceramic-based fibrous composite material constituting of a matrix 10 composed mainly of SiC formed by reactive sintering and SiC fibers 11 compounded in the matrix 10. The composite material is formed to the armor 6 so that the armor 6 can receive heat fluxes (heat loads) P1 from plasma through its surface F1 having the highest thermal conductivity by controlling the arranging state of the fibers.

摘要： PURPOSE: To make it possible to increase the rigidity and decrease the electromagnetic force by arranging diverter modules in many rows to which armors are attached on a supporting stand element face opposite to plasma and by fastening adjoining modules respectively through an insulator. CONSTITUTION: A diverter is divided into partial sectors in the circumferential direction of a torus. The partial sector consists of an assembly 16 integrated by fastening diverter modules 15 which are multi-divided in the circumferential direction and a connecting plate 13 installed on the back sides of the assembly 16. Armors where cooling pipes 9 are buried are arrchored on the face of the module 15 opposite to the plasma are fixed on a supporting stand element 11a by soldering it up, for example, with silver or through diffused junction. An electric insulator 7 is installed respectively between adjoining modules 15, and an insulating bush 19 is fitted into a spot-faced hole 18 of the element 11a and is fastened by piercing it with a tightening bolt 20. This makes it possible to substantially abate the electromagnetic force generated in the reduction of plasma.
