摘要

IN THE PROCESS FOR RECONSTRUCTING A NUCLEAR FUEL ASSEMBLY INCLUDING A TOP END MOUNTING PLATE 32 WELDED TO GUIDE TUBES OR SOCKS 50 OF CONTROL BARS, THE GUIDE TUBES 50 ARE FIRST CUT FROM THE MOUNTING PLATE 52 BELOW THE WELD, WE SEPARATE THE UPPER END OF THE TUBE-GUIDE 50 CUT, WE MACHINE A NEW UPPER END 24 BY FORMING GORGES 74 IN THE PASSAGES 72 FOR THE CONTROL BARS OF ITS MOUNTING PLATE, WE INSERT THE TUBES- CUT GUIDES 50 IN THE PASSAGES 72 OF THE MODIFIED TOP NOZZLE 24 AND THE GUIDE TUBES 50 protrude CIRCUMFERENTIALLY INTO THE GROOVES 74.
