Nuclear reactor installation

Abstract

Abstract EACH FUEL AGGREGATE USED FOR FUELING THE REACTOR IS LOCKED AND SEALED WITHIN TIS RESPECTIVE FUEL CHANNEL BY MEANS OF END PLUG PORTION. FOR UNLOCKING THIS PORTION, RELEASING THE SEAL AND DISPLACING THE FUEL AGGREGATE OUT OF THE CHANNEL, A MECHANISM IS USED WHICH INCLUDES A CASING FOR ENGAGING THE CHANNEL AND TWO COAXIAL TUBES FOR ENGAGING THE END PLUG PORTION. THE TWO TUBES ARE MOVED TOGETHER ALONG THEIR LONGITUDINAL AXIS, RELATIVELY TO THE CASING, ANDINDEPENDENTLY OF THIS MOTION, THE INNER ONE OF THESE TUBES IS MOVED ALONG THE SAME AXIS RELATIVELY TO THE OUTER TUBE. THE END PLUG PORTION SIMILARLY COMPRISES TWO COAXIAL TUBULAR MEMBERS, THE OUTER ONE OF WHICH IS PROVIDED WITH A SET OF CAPTIVE BALLS AND THE INNER ONE OF WHICH HAS A SRUFACE PORTION ARRANGED TO FORCE THESE CAPTIVE BALLS INTO A LOCKING GROOVE PROVIDED IN THE INNER SURFACE OF THE CHANNEL. THE OUTER AND INNER TUBES OF THE RAM MECHANISM ARE SIMILARLY PROVIDED WITH A SET OF CAPTIVE BALLS TO LOCK THE TUBES TO THE OUTER AND INNER TUBULAR MEMBERS OF THE END PLUG PORTION RESPECTIVELY. THE INNER TUBE FURTHERMORE SERVES TO DISPLACE THE INNER TUBULAR MEMBER RELATIVELY TO THE OUTER TUBULAR MEMBER TO ENGAGE OR DISENGAGE THE CAPTIVE BALLS OF THE END PLUG PORTION TO OR FROM THE CHANNEL GROOVE. THE OUTER TUBE FURTHERMORE SERVES TO ACTUATE MEANS FOR RELEASING THE SEAL OF THE END PLUG PORTION. D R A W I N G
