    • In a clamping jig and system for inspecting spacer grids for a nuclear fuel assembly, the jig firmly and precisely clamps a variety of grids on a measurement stage moving at high speed so that, among constituent parts of the nuclear fuel assembly, the spacer grids can be inspected using a non-contact measurer. The clamping jig includes a frame having a plurality of holding recesses into which the corresponding spacer grids are inserted, supporting means mounted in each holding recess of the frame to allow each spacer grid to be adjusted from below so it can be maintained in a horizontal state, clamping means installed around each holding recess to clamp two adjacent sides of each spacer grid to a corner of the respective holding recess, and resilient means installed on the sides opposite the clamping means and resiliently supporting the other two sides of each spacer grid.
    • 在用于检查用于核燃料组件的间隔栅格的夹紧夹具和系统中,夹具牢固且精确地夹紧在高速移动的测量台上的各种格栅,使得在核燃料组件的组成部分之间,间隔栅格可以 使用非接触式测量仪进行检查。 夹持夹具包括具有多个保持凹槽的框架,相应的间隔栅格插入其中,支撑装置安装在框架的每个保持凹部中,以允许每个间隔栅格从下方调节,使得其可以保持在水平状态 夹紧装置安装在每个保持凹槽周围,以将每个隔离栅格的两个相邻侧面夹持到相应的保持凹部的角部,以及安装在与夹持装置相对的侧面上的弹性装置,并且弹性地支撑每个隔离栅格的另外两侧。
