    • A key member, a method for insertion and/or removal of the fuel rods in a nuclear fuel assembly using the key member and a method of disassembling the nuclear fuel assembly using the same key member are disclosed. The key member has first projections and second projections formed on the opposite faces of an elongated key body. In the insertion or removal of the fuel rods or in the disassembling the nuclear fuel assembly, the key member is inserted into the grid and rotated to bring the first projections and the second projections into engagement with the straps of the grids and the springs on the straps to thereby the springs are deflected in a direction away from the dimples opposing to the springs. In this situation, the insertion and removal of the fuel rods can be carried out. Further, in disassembling the nuclear fuel assembly, space required for inserting the key member into the grids may be ensured by subjecting prescribed portions of control rod-guide pipes and instrumentation pipes to cutting work and bulging the cut ends to move the cut end away from that of the opposing cut ends of the cut piece. The space may be formed by removing the control rod-guide pipes and instrumentation pipes after having formed slits in the pipes.

    • In the nuclear fuel assembly, a plurality of plate-shaped straps are assembled perpendicularly to each other into a grid shape so as to construct a supporting grid providing with a plurality of cells each of which inserts a nuclear fuel rod. A cell-size inspection device which inspects the size of each cell of the supporting grid is constructed by a base, a movable plate, a plurality of pin gauges and a sensor. The supporting grid is mounted on the base, while the movable plate is provided such that it can relatively move with respect to the base in a longitudinal direction of the cells. The pin gauges are provided on the movable plate such that they can freely slide along the longitudinal direction of the cells. When the movable plate is moved toward the supporting grid, each of the pin gauges is to be inserted into each of the cells. The sensor senses whether the pin gauge is relatively moved from the predetermined position of the movable plate. By simply inserting the pin gauge into the cell, it is possible to inspect the cell size with respect to a plenty of cells provided in the supporting grid. Thus, it is possible to inspect all of the cells in an extremely short time, which remarkably reduces the time and cost required for performing the inspection process on the nuclear fuel assembly.
    • 在核燃料组件中,将多个板状带彼此垂直地组装成格子形状,以便构成一个支撑栅格,该栅格提供多个单元,每个单元插入一个核燃料棒。 检查支撑架的每个电池单元尺寸的电池尺寸检查装置由基座,可移动板,多个针规和传感器构成。 支撑网格安装在基座上,而可移动板被设置成使得其可以在单元的纵向方向上相对于基座相对移动。 针规设置在可动板上,使得它们可以沿着电池的纵向方向自由滑动。 当可移动板朝向支撑格栅移动时,每个销量规插入到每个单元中。 传感器感测针规是否从可动板的预定位置相对移动。 通过简单地将针规插入电池,可以相对于在支撑电网中提供的大量电池检查电池尺寸。 因此,可以在极短的时间内检查所有的电池,这显着地减少了对核燃料组件执行检查过程所需的时间和成本。

    • The present invention relates to a pull-in rod type loader for loading fuel rods efficiently and conveniently from a fuel rod magazine to a fuel assembly. The control rod pipes and fuel rods are held in assigned grid cells, respectively termed pipe-cells and fuel-rod-cells, in each quadrant section of a grid. The control rod pipes are disposed in a quadrant so that the locations of the pipe-cells assigned for the guide pipes in one quadrant are symmetrical with respect to a central rotational axis of the apparatus. The grid cells and the pull-in loader are both aligned with respect to a central rotational axis. To load the fuel rods into the fuel assembly, only the pull-in rods need to be operated for every 90 degree rotation of the loader about the central axis, because the locations of the pull-in rods correspond exactly with the grid cells assigned to hold fuel rods. This type of loader does not require complex switching devices required in the conventional pull-in rod type of loaders, and the assembling operation can be carried out efficiently and quickly.
    • 本发明涉及一种用于将燃料棒从燃料棒料箱有效地方便地装载到燃料组件的拉入式装载机。 控制棒管和燃料棒在网格的每个象限部分中分别被称为管电池和燃料棒电池。 控制棒管设置在象限中,使得分配给一个象限中的引导管的管腔的位置相对于设备的中心旋转轴线对称。 网格单元和拉入装载机都相对于中心旋转轴线对准。 为了将燃料棒装载到燃料组件中,由于拉入杆的位置与分配给燃料棒的电网单元完全对应,所以只需要在装载机围绕中心轴的每90度旋转时操作拉入杆 拿着燃料棒。 这种装载机不需要传统的拉入式装载机所需的复杂开关装置,并且组装操作可以有效且快速地进行。

    • To etch the back side of a wafer, the front side of the wafer is first coated with a positive photoresist to form a protective film. The surface of the protective film is hardened by heating, or by heating and ultraviolet curing. The wafer is then placed in a plasma etching apparatus with the hardened surface of the protective film in contact with an electrode of the etching apparatus, and the back side of the wafer is patterned by plasma etching. When the etching is completed, the front side of the wafer is separated from the electrode and the wafer is removed from the plasma etching apparatus. The hardened positive photoresist prevents the wafer from sticking to the electrode.

    • Circuit elements, such as aluminum interconnects, and a protective film for protecting these circuit elements are formed on a surface of a semiconductor substrate. Resist is formed covering the protective film. The semiconductor substrate on which the resist covering the protective film is formed is dipped into pure water so as to allow the water to filter into a gap between the resist and semiconductor substrate. Then the semiconductor substrate having the resist thereon is dried in high temperature air, and the resist is adhered to the semiconductor substrate by a sticking function due to the surface tension generated when the water is decreasing. The semiconductor substrate to which the resist is adhered is cleaned by a hydrogen fluoride aqueous solution.
