The 3D measuring device is selected as a prototype basis for the development of measuring device in accordance with the technical requirements for measurement of nuclear fuel assembly (FA) skeleton, and the requirements for the device function and the accuracy in measurement are presented. With the established measurement benchmark, it is analyzed for the planeness of skeleton socket end faces, the perpendicularity of Rb faces, the whole length of skeleton, the position and dimen-sions of spacer grids, and the measuring principle for perpendicularity of each level spacer grid against the skeleton axis. The body structure of measuring device, the control system, the probe and seat system, and the measuring program are designed. Comparative analyses on the repeatability and reproducibility of the measurements by the automation measuring device prove that the device can quickly and visually measure various dimensions of skeleton profile and can immediately detect any abnor-mality, ensuring the precision of skeleton examinations as well as the timeliness and accuracy of the examination data.
