摘要： PURPOSE: To improve the detecting accuracy of a broken fuel system detector by providing a gap between an outer cap and an inner cap to thereby detect the broken fuel system regardless of the difference in elongation of a fuel assembly.
CONSTITUTION: A guide tube is secured to an outer cap 14, and a sampling tube 9 is flexibly attached to the guide tube. An inner cap 17 is axially slidably attached to the guide tube with a gap G provided between the inner cap 17 and the outer cap 14. A shipping cap 2 is moved onto the fuel assemblies 5, 16 to be detected at fuel inspecting time, and a gasket 19 is seated on the assemblies 5, 16. Since the inner cap 17 can elevationally move, even if the fuel assemblies differ in length, and the tube 9 is flexible, the cap 2 can be easily attached to the fuel assemblies to accurately detect the broken fuel system of the fuel assemblies by varying the sampling position.

摘要翻译：目的：通过在外盖和内盖之间提供间隙来提高破坏的燃料系统检测器的检测精度，从而检测破坏的燃料系统，而不管燃料组件的伸长差异如何。构成：导管固定在外盖14上，采样管9柔性地连接在导管上。内盖17可轴向地滑动地附接到引导管上，间隙G设置在内盖17和外盖14之间。运输盖2移动到燃料组件5,16上以在燃料检测时间被检测，并且垫圈19位于组件5,16上。由于即使燃料组件的长度不同，并且管9是柔性的，内盖17也可以垂直移动，所以能够容易地将盖2附接到燃料组件上通过改变采样位置来检测燃料组件的破坏的燃料系统。

摘要： PURPOSE:To improve the safety of work, by driving a cylinder after detecting the insertion conditions of brackets by mounting detectors to a hanger box. CONSTITUTION:Detectors 29, 30 are installed to the a hanger box 12 to detect the insertion condition of a pin 17 of the hanger box 12 of a bracket 21 or a bracket 22. When making sure that the pin 17 can move, the bracket 21 and the bracket 22 of the hanger box 12 are locked by driving a cylinder 15. When the pin 17 reaches a final movement location, a detector 23 operates, the pressure of compressed air is displayed by means of a pressure gauge and operators can confirm joining. When separation operation, the cylinder 15 is inversely driven, a detector 35 works when the pin 17 reaches a return terminal, pressure is displayed by means of the pressure gauge and separation can be confirmed.
