Double container reactor vessel

Abstract

Abstract MEANS FOR SUSPENDEDLY MOUNTING A DOUBLE CONTAINER REACTOR VESSEL WITHIN A VESSEL CAVITY FORMED IN A FOUNDA TION STRUCTURE IN A MANNER SUCH THAT, IN THE EVENT OF FAILURE OF THE OUTER VESSEL IN ANY LOCATION, THE INNER VESSEL WILL REMAIN SECURED TO THE FOUNDATION STRUCTURE. THE MEANS COMPRISES THE PROVISION OF RADIAL FLANGES ON THE SHELLS AND CLOSURE COVERS OF THE INNER AND OUTER CONTAINER VESSELS ARRANGED SUCH THAT THE INNER VESSEL FLANGES ARE RETAINED IN SANDWICHED RELATION BETWEEN THE OPPOSING FACES OF THE OUTER VESSEL FLANGES. ANNULAR SHOULDER MEANS ARE PROVIDED ON THE FOUNDATION WALL TO VERTICALLY SUPPORT THE ASSEMBLED VESSEL STRUCTURE BY ENGAGEMENT WITH THE OUTER VESSEL SHELL FLANGE. AN ANNULAR LOCK RING RELEASABLY ATTACHED TO THE FOUNDATION PRESENTS A BEARING FACE ADAPTED TO ENGAGE THE OUTER VESSEL CLOSURE COVER FLANGE TO PREVENT UPWARD MOVEMENT OF THE RETAINED FLANGES IN THE EVENT OF A REACTOR ACCIDENT.
