摘要： PURPOSE:To improve stability when a copper-aluminium compound material is used as a stabilizing material by containing an aluminium material having a copper coating layer in the stabilizing material, and setting a thickness of the copper coating layer equal to or thinner than 35mum. CONSTITUTION:In a superconductor 11, a superconducting wire 3 formed of Nb3S or NbTi and so on of a copper matrix is buried in a copper stabilizing material 2. A groove 4 extending along the wire 3 is arranged on the outer surface of the copper stabilizing material 2, and an aluminium material 13 having a copper coating layer 12, that is, a copper clad-aluminium material 14 is installed in this groove 4 through solder, and a stabilizing material 15 is constituted of the material 2 and the material 14. This layer 12 is formed by means of metal plating and so on, and the thickness is set equal to or thinner than 35mum. Among the layer 12, a part situated in the groove 4 contributes to adhesiveness with the solder, so that stability of the superconductor 11 can be improved significantly. Thereby, the stability can be improved without deteriorating productivity.

摘要： PURPOSE:To lower the composite specific resistance at very low temperatures of a stabilizer made from high purity aluminum. CONSTITUTION:A composite superconductor 20 is formed by joining a composite material 21 and a superconducting wire 10 together using solder 15, the composite material 21 comprising high purity aluminum 11 of rectangular cross section and a covering material 12 formed on the outside of the high purity aluminum from a material with a Hall coefficient of the same sign as that of the high purity aluminum. When in use the composite superconductor is disposed with the broad surface of the high purity aluminum 11 being parallel to an external magnetic field H. Since the sign of the Hall element of the high purity aluminum is the same as that of the Hall element of the covering material at very low temperatures, the composite specific resistance of the composite material 21 can be reduced significantly by disposing the composite superconductor in this way, and as a result the specific resistance of the whole conductor can be approximated to that of the high purity aluminum.

摘要： PROBLEM TO BE SOLVED: To shorten the time required for periodic checking by making on-line maintenance of a reactor auxiliary component sea water cooling system (RSW) and an emergency diesel generator(D/G) possible. SOLUTION: A high pressure core cooling system (HPCF8, RCIC6) is constituted of 3 divisions, a low pressure core cooling system (LPFL) 1 and a residual heat removal system (RHR) 2 are constituted of 4 divisions, the piping of a reactor auxiliary component cooling system (RCW) is constituted of 2 loops, and two or more reactor auxiliary component cooling system pumps are provided in one loop. A reactor auxiliary component sea water cooling system (RSW) is constituted with 2 or more loops for one loop, i.e., 4 loops in total, and an emergency power source (D/G5, etc.), for supplying electricity to them is constituted of 4 divisions. Owing to the increase of RHR from 2 systems to 4 systems by this constitution, the possibility of reactor cooling failure during plant operation is reduced. Also owing to the increase of D/G5 from 3 to 4, the probability of core damage due to loss of power is reduced.

摘要： PURPOSE:To obtain an oxide superconductor having a high critical current density by moving a starting material consisting of a material contg. the oxide superconductor from the low-temp. region to the high-temp. region with a region having a temp. gradient in between. CONSTITUTION:An oxide superconductor or the material contg. the elements constituting the superconductor is used as the starting material. The starting material is moved from the low-temp. region to the high-temp. region with a region having a temp. gradient in between and heat-treated to obtain the desired oxide superconductor. An oriented structure is obtained with a relatively low temp. gradient by this process. The critical current density of the bulk or wire of the oxide superconductor is improved in this way. The critical current density is improved especially in the magnetic field essential to its application. Furthermore, even an oxide superconductor phase having a narrow stable region is homogeneously produced over a wide range.

摘要： PURPOSE:To form a film having a good adhesive property at a high film forming speed by providing a container for housing a material to be deposited by evaporation, a holder member for a substrate, a laser light irradiating means, a gas injecting means and an ion forming and accelerating means in a vacuum chamber. CONSTITUTION:Gas, such as N2, is injected from a cylinder 17 toward the inside surface of a window 14 for transmission of laser light 24 from the ejection hole on the inner peripheral surface of an annular gas ejecting member 15 and a glow discharge is generated between an electrode 19 and the holder member 3 to ionize the gas supplied into a vacuum chamber 1. The powdery material 23 to be deposited by evaporation in the container 4 is irradiated with the laser light 24 through the transmission window 14 to melt and evaporate the mateiral. The gas of the material 23 is sucked and deposited on the substrate 22 on the holder member 3 by the voltage gradient between the holder member 3 and the electrode 19. by which the film is formed. The gaseous N2 or the like is injected from the above-mentioned member 15 to the inside surface of the window 14, by which the deposition of the material 23 on the inside surface of the window 14 is suppressed and the deposition rate of the material 23 on the substrate 22 is maintained in a high state over a long period of time.
