摘要： PURPOSE:To shorten the time required for the entire repairing work by reducing the exposure of an operator at the time of transporting a radioactivated diverter to a repairing place, and further facilitating the transporting work. CONSTITUTION:A circumferential pool chamber 21 for storing water 22 is disposed in the periphery of the nuclear fusion reactor, and a radioactivated diverter 6 is filed in water 22 of the chamber 21, and then transported in the state imersed in the water 22. At the time of normal operating of generating a plasma, a leak valve is installed to discharge high-temperature high-pressure gas to the chamber 21 when the pressure in a vacuum vessel 3 is abnormally raised. Accordingly, since the water 22 shields the radiation, the operator can approach, the operator can work while visually confirming the state of the diverter 6 under the water by the operator himself. Therefore, the work is facilitated, and the time required for the work can be shortened.

摘要： PURPOSE:To exercise highly precise control even in occurrence of a disturbance, by exercising control over a system while forecasting fluctuations of the system. CONSTITUTION:A nuclear-fusion experimental device is unable to cope with complicate motion of plasma only in programmed process. This complicate motion acts upon the process as a disturbance. Condition judgement part 5 receives a coil voltage and electric current from coil 3 and fetches signals of a plasma current, density, position, shape, etc., from plasma 4. On the basis of those input signal, whether the motion can be regarded as a disturbance is judged and according to the result, the fluctuation extent is forecasted on the basis of various fluctuation data due to the right previous disturbance to exercise control. For this purpose, the frequency and voltage of the AC electric power source are not controlled directly and the output of thyristor phase controller 14 influenced by them is controlled right previously.

摘要： PURPOSE:To provide an integrated coil apparatus characterized by high reliability in mechanical strength and simple winding work of binding material by covering a part between neighboring coils around which strip-shaped band is wound and the outer surface of a spacer with a pair of connecting pieces which comprise nonmagnetic material and a U-shaped cross section. CONSTITUTION:A spacer 18 is provided between neighboring coils 11 and 14. Under the state wherein the coils 11 and 14 and the spacer 18 are in close contact, the outer surfaces of the coils and the spacer are covered with a pair of connecting pieces 21 and 22 so that end surfaces 21a and 22a are connected to each other at the side part of the coil on the opposite side of the space 18. The entire surface of the outer parts of both connecting pieces 21 and 22 are wound with a strip-shaped binding material, e.g. a binding tape 19. Thus the coils 11 and 14 are integrated as a unitary body. When the coils 11 and 14 are electrified, electromagnetic forces act in the conflicting directions, and the interval between both coils 11 and 14 tends to expand. However, the deformation is suppressed with the connecting pieces 21 and 22 the tensile regidity of the binding tape 19 that is wound around the pieces.
