Abstract

THE SHIELD PLUG OF A LIQUID METAL COOLED FAST BREEDER REACTOR WHICH USES A HOT CELL REFUELING SYSTEM HAS A METAL ACCESS ENCLOSURE SEALED TO ITSUPPER SURFACE. THE ENCLOSURE CONTAINS THE CONTROL ROD DRIVE MECHANISMS, REACTOR CLOSURE BOLTS AND OTHER COMPONENTS AS ARE GENERALLY MOUNTED ON A SHIELD PLUG, AND AN AIR ATMOSPHERE IS PROVIDED WITHIN THE ENCLOSURE. A HORIZONTAL EXTENDING BELLOWS-LIKE STRUCTURE ALLOWS PERSONNEL ACCESS TO THE ENCLOSURE FROM THE EXTERIOR OF THE HOT CELL.
