摘要： PURPOSE:To obtain a vacuum flange with an improved reliability to leak by providing in low parts on the outer diameter side and the inner diameter side of knife edge parts formed in flange joint surfaces respectively to be engaged with a circular gasket alone the outer diameter and the inner diameter. CONSTITUTION:An in low part 5a is provided on the outer diameter side of knife edge parts 3 formed in joint surfaces of a pair of steel metal flange parts 1, and an inlow part 5b is also provided on the inner diameter side, so a circular gasket 4 is engaged between the knife edge parts 3 along the outer diameter and the inner diameter to be inserted. In this constitution, deformation of the circular gasket 4 to occur when the steel metal flange parts 1 are tightened by a bolt 2 to let the knife edge part 5 bite the circular gasket 4 is limited by the in low parts 5a, 5b, and further large deformation us prevented. Creeping phenomenon, especially reduction of the tightening force of the bolt 2 corresponding to increase of the bite quantity of the knife edge parts 3 at the time of high temperature baking, can therefore be reduced to be small, and the sealability can be maintained.

摘要： PURPOSE:To prevent the fall accident of a nuclear fusion reactor component due to electromagnetic force by providing an apparatus for supporting the electromagnetic force acting on the component by fluid pressure to the nuclear fusion reactor component on the side of the shield body thereof. CONSTITUTION:The electromagnetic force support apparatus 10 provided o the side of the inside shield body 3 of a sub-limiter SL 9 is equipped with a plurality of hydraulic cylinders 11 operated by water pressure and constituted so as to extend a plurality of the support legs 12 being in contact with the shield body 3 to push out the SL 9 from the surface of the shield body 3 toward a plasma 4. When the pressure of the hydraulic chamber 18 of the cylinder 11 is made higher than that of the hydraulic chamber 17 thereof during the operation of a nuclear fusion reactor, the electromagnetic force F acting on the SL 9 is supported by the apparatus 10. Therefore, the fall accident of the SL 9 due to electromagnetic force F can be prevented at the time of plasma fission. When the SL 9 is drawn out of a vacuum container, the pressure of the hydraulic chamber 18 is made lower than that of the hydraulic chamber 17 and th legs 12 are retracted into the cylinder main body 15.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable vacuum vessel by discharging remaining gas in a connection part to the outside of the vessel via an exhaust path, thereby preventing a connecting liner from being broken due to the remaining gas, and detecting leak from the connection part of inner wall. SOLUTION: An exhaust groove 10 is formed between a main board 6 and a protection board 7 so that it is arranged along a connection part of an inner wall 1 of a vacuum vessel, and an exhaust pipe 12 is connected at its one end to an exhaust hole 11 penetrating the main board 6 while it is communicated with the groove 10. To the other end of the pipe 12 a leak detector 13, an exhaust pump 14, an analyzer 15 and a display 16 are connected. By the drive of a pump 14, remaining gas of connection part 8 is discharged to the outside of vacuum vessel from the groove 10 and the pipe 12. Accordingly, breakage of connection liner 9 caused by the remaining gas generated at the time of welding can be prevented, and the part of main board 6 and the liner 9 can be sealed in vacuum. Leak from the connection part 8 of the inner wall 1 can be detected by a detector 13. An analyzer 15 reserves and relays the result of detection of the detector 13 while a display displays thereon an output of the analyzer 15.

摘要： PURPOSE:To intend a firm supporting to a supporting ring by connecting each outboard side supporting ring of a vacuum vessel with a supporting beam and by providing vacuum vessel supports on the supporting beam at the same interval. CONSTITUTION:A space between a normal supporting ring 4 and a deformed supporting ring 4A is supported by a supporting beam 13 and, to the beam 13, vacuum vessel supports 8 supporting a vacuum vessel 1 are attached at the same interval. One end of the beam 13 is fixed to the ring 4 and the other end has a constitution to be fitted into a horizontal groove provided on the ring 4A which is eccentrically placed. In case that a vertical electro-magnetic force is charged to the support 8 attached to a position eccentric against a center of the ring 4A, the load is transferred to the rings 4 and 4A through the beam 13. Therefore, by setting a bending stiffness of the beam 13 to be an appropriate value, any overturning moment is not generated at the rings 4 and 4A and also a displacement of the support 8 becomes rather small, and therewith, the vessel 1 can be firmly fixed to the rings 4 and 4A.

摘要： PURPOSE:To make the plate thickness of a flange part thinner and to reduce the number of bolts as compared with one heretofore by obtaining the thickness of a metal seal flange part and the number of bolts required for jointing the flange as the functions of a bolt pitch circle. CONSTITUTION:In the knife edge type metal seal flange, a copper gasket 4 is inserted between a pair of metal seal flange parts comprising austenite stainless steel material, the inner end sides of whose flange junction planes are formed in a knife edge part 3 with a blade tip angle ranging from 70 deg. to 100 deg.. The thickness of flange parts 1a, 1b and the number N of bolt 2 are so arranged to fall into the range of values as obtained from Formula I.
