X-Ray station for tomographic inspection of fuel element welded seams


Technical inspection of quality of fuel element welded seams for nuclear reactors.


It is based on X-Ray examination at different angles, transformation of shadow images into the digital form and program reconstruction of fuel element inner structure.

as independent working place of quality inspector. It contains, besides measuring unit, shoots for loading of inspected articles and unloading of fitted and rejected ones as well as the transport mechanism for the article displacement inside the system.
