Description

technical field [0001] The invention belongs to the technical field of nuclear industry, and in particular relates to a circular runout measuring device of MOX components. Background technique [0002] Nuclear safety is the lifeline of nuclear power development. In order to ensure the safe operation of nuclear reactors, it is necessary to perform circular runout detection during the production process of nuclear fuel assemblies (MOX assemblies) to ensure that nuclear fuel assemblies fully meet the requirements for use; moreover, for the detection data of fuel assemblies It can also provide correct feedback for its manufacturing, thereby guiding process improvement, thereby increasing product yield. [0003] In the prior art, the detection of MOX components usually adopts the method of manual detection. This method not only has low measurement accuracy, but also has low efficiency and low precision. Moreover, due to the radioactivity of MOX components, long-term exposure has ...
