AI Technical Summary
The alignment of existing fuel assembly equipment does not meet the requirements, which may cause damage to the surface of fuel rods and impact on grid cells during the rod feeding process, affecting product quality and equipment lifespan.
By establishing a reference spatial coordinate system, the basic parameters of the fuel assembly equipment are measured using a laser tracker, and the alignment deviations of the rod pulling machine, the flipping platform, and the pre-loading box platform are calculated. The positioning axis of the alignment tooling and the target ball positioning plate are used for precise measurement and correction.
Effective detection of fuel assembly equipment alignment reduces fuel rod surface damage, prevents grid impacts during fuel rod feeding, and improves assembly quality and equipment lifespan.
