    摘要: In a canister horizontally installed and housed inside a concrete silo, at least two temperatures out of a temperature TB at a canister bottom portion to be one end portion in a lateral direction in a horizontally-installed attitude, a temperature TSB at a canister side surface lower portion located below a horizontal plane passing through a center of the canister, a temperature TT at a canister lid portion to be the other end portion in the lateral direction, and a temperature TST at a canister side surface upper portion located above the horizontal plane passing through the center of the canister are monitored, and occurrence of leakage of an inert gas inside the canister is detected when there is a change in a temperature difference between the at least two temperatures.

    摘要: The present invention provides a Bi2223 based thick film that does not peel off when a thermal or a mechanical shock is applied to a base or an oxide superconductor thick film or the like in the middle of a manufacturing process and a method of manufacturing the same An oxide superconductor paste 1 having a mixing ratio of Bi2212 composition is applied to a base 3, dried, burned, and thereafter burned at a temperature approximate to its melting point to obtain a partially molten layer 4. Next, an oxide superconductor paste 2 having a mixing ratio of Bi2223 composition is applied to the partially molten layer 4, dried, burned, compressed by a CIP, and thereafter repeatedly burned and compressed for a predetermined number of times to obtain the base 3 having a desired superconductor thick film 5 formed thereon.

    摘要: The present invention relates to high-density coal-water mixed fuel and a producing method thereof and aims to reduce an amount of dispersant to be used in the coal-water mixed fuel having the good fluidity with the increased density and obtain the a coal-water mixed fuel from pulverized coals produced by dry milling at low cost. According to this invention, in case of obtaining the high-density coal-water mixed fuel such as a CWM by mixing the pulverized coals ground to provide a predetermined particle size distribution, water and the dispersant, the hydrophilic colloid which causes the protective effect with respect to the pulverized coals is added and mixed preferably before adding the dispersant so that the high-density coal-water mixed fuel which includes the hydrophilic colloid and a reduced amount of a surface active agent used can be provided. An amount of the hydrophilic colloid to be added is less than 1 wt % of the entire CWM and larger than an amount for causing reciprocal aggregation with the pulverized coals, or more preferably it is in the order from ppm to ppt. Further, when the pulverized coals are rubbed together and the angles thereof are shaved off for production from the pulverized coals, the pulverized coals are spheroidized without extremely being minimized from their original particle size, and superfine particles in the coal particles are generated, thereby enabling adjustment to provide a preferable particle size distribution as the CWM.

    摘要: A cooling air amount adjustment device of a concrete cask is provided. The device includes at least one of an air outlet port opening level adjustment mechanism and an air inlet port opening level adjustment mechanism which are adapted to automatically perform adjustment to reduce a flow rate of a cooling air when a temperature of the cooling air at an air outlet port is lower than an adjustment reference temperature, and adjustment to increase the flow rate of the cooling air so as to restore the flow rate of the cooling air when the temperature of the cooling air at the air outlet port is higher than the adjustment reference temperature.
