Assembly for sliding and inspecting pellets in an apparatus for inspecting surface defects in nuclear-fuel pellets

摘要

A SURFACE DEFECTS INSPECTION DEVICE ON FUEL PADS HAS A FEED CONVEYOR, A DISCHARGE CONVEYOR, AND A SET OF SLIDING AND INSPECTION BETWEEN BOTH CONVEYORS. THE SET INCLUDES: A) A SLIDER FORMED BY A SLOPED TRACK THAT HAS AN END OF EXIT AND ONE OF ENTRY TO A LEVEL HIGHER THAN THAT, ADJACENT TO THE RESPECTIVE CARRIERS; B) AN INSPECTION STATION SITUATED BETWEEN THE ENDS OF THE TRACK INCLUDING ACOUSTIC REFLECTORS THAT DEFINE AN ANNULAR INSPECTION CHAMBER THAT COMPLETELY SURROUNDS THE PAD SURFACE WHEN IT IS CROSSING THE PASSEL. THE INCLINED TRACK HAS AN UPPER PART THAT EXTENDS UP TO THE INSPECTION CHAMBER AND A BOTTOM PART THAT EXTENDS FROM THE INSPECTION CHAMBER AND HAS A SLIGHTER SLOPE THAN THE UPPER TO PRODUCE THE DECELARATION OF THE PAD.
