摘要： PURPOSE:To avoid welding deformation in liquid reserving part and improve dimensional accuracy and fabrication capability by forming upper lid and bottom plate as a whole without seam and arranging a medium strengthening ring to connect the inner body and outer body. CONSTITUTION:After connecting upper outer body 12, medium strengthening ring 10 and outer body 4 to a horizontal upper lid 1 with butt welding, supply and drain pipes and air sending pipe 9 and the like arranging in annular space are connected at the boundary of pipe stage 8 on the lower surface side of the upper lid 1. Then, upper inner body 11 and inner body 3 are butt welded and finally the bottom plate 2 is fixed with butt welding slantingly to the horizontal surface to form an annular space and constitute an annular tank 21. In this constitution, as the ring 10 has a double purpose of a rag support plate ring 5, welding and machining of ring 5 are omitted and so fabrication capability increases and material loss is reduced. And as the upper lid 1 and the bottom plate 2 are formed in one, the generation of lack is eliminated and strength along the periphery becomes almost even. Furthermore, due to the reduction of welding lines, fabrication deformation is eliminated and thus fabrication accuracy is improved.

摘要： PROBLEM TO BE SOLVED: To provide a nuclear fuel replacement device for performing replacement work of a fuel assembly and reactor-core internal structure in a short period of time. SOLUTION: This nuclear fuel replacement device comprises a traveling carriage traveling on a rail track 18 provided above a nuclear reactor pressure vessel 15, a traversing carriage moving on the traveling carriage in a direction perpendicular to the track, and a fuel gripper 9 mounted on multi-stage extension masts 1 and 2 hung down from the traversing carriage for performing insertion and extraction of the fuel assembly 13 with respect to the pressure vessel, and adapted to load the fuel assembly to the pressure vessel and extract it therefrom. The extension masts are each given an upper/lower two-part structure comprising upper mast parts 1a, 1b, 1c, ... and lower mast parts 2a, 2b, 2c, .... The fuel gripper is moved up and down while the upper mast parts are used to guide the lower mast parts. When handling the fuel assembly, the construction of upper/lower two-part type masts dispenses with speed reduction at each joint between mast stages as seen in relevant art. This resultantly shortens per-unit handling time for fuel assemblies. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PURPOSE:To attenuate vibration loaded on the bearing of a cantilever structure part by equipping an attenuator for attenuating the axial vibration of a rotor or the external vibration transferred to the rotor, a vibration detecting means for detecting external vibration and a voltage signal generating means which gives an electric field to the electric viscous fluid when the vibration waveform detected by this vibration detecting means is inputted and the value of wave height of this vibration waveform exceeds the set value. CONSTITUTION:When voltage is impressed to electrodes 42, 45 from a driving power source 38, viscosity of fluid present in the electric field of electric viscous fluid 46 is controlled according to the intensity of the electric field. When earthquake waveform measured by a seismometer 36 is inputted to an ON-OFF waveform generator 37 and the value of wave height exceeds the reference value (a), this generator 37 is turned-on. From a point of this time, volt is impressed to the electrodes 42, 45 of an oil film damper 40 at about 10 seconds T via the driving power source 38. Thereby, since attenuation constant is made large, response of the rotor is made small. When earthquake is put down, impression of voltage to the oil film damper 40 is turned-off. Since the attenuation constant is made small, the rotary shaft returns to the ordinary supporting conditions.

摘要： PURPOSE:To prevent generation of corrosion products in a power generation plant by filtering off impurities in a high temperature feed wafer to the plant with a filter composed of permeable ceramics. CONSTITUTION:A strainer 50 equipped with ceramic filters is arranged between an economizer 24 and a feed water heater 22 of a power generation plant as a feed water filtration apparatus. The ceramic strainer 50 consists of a closed vessel equipped with three nozzles, i.e., a feed water inlet 51, feed water outlet 52 and a condensed liquid outlet 53. Ceramic filters 57 are installed removably at partition plates 56 in the closed vessel. The ceramic filter 57 has a hollow tubular shape and is composed of a porous substance such as alumina. The feed water has its impurities removed by fine pores formed in the ceramic filters 57 and oozes out of the outer face of filters. It is possible, therefore, to remove efficiently the impurities which cause scale formation in the pipings.
