MODEL BUSS (R-1). MAJOR COMPONENTS OF THE PACKAGING INCLUDE THE CASK BODY & LID, BASKET, IMPACT LIMITERS, PERSONNEL BARRIER, AND SKID. THE CASK BODY IS A CYLINDRICAL FORGING WITH OUTER DIMENSIONS OF 137.8 CM DIAMETER & 124.5 CM HIGH. THE CAVITY IS 51.4 CM IN DIAMETER AND 58.4 CM HIGH. ON THE OUTSIDE SURFACE OF THE CASK BODY, ELEVEN, 10.2-CM HIGH INTEGRAL, NON-WELDED FINS ARE SITUATED SYMMETRICALLY AROUND THE CIRCUMFERENCE OF THE CASK FOR HEAT REMOVAL. THE CASK LID IS A SINGLE 32.6-CM THICK FORGING AND IS BOLTED TO THE CASK BODY USING 12 CORROSION-RESISTANT STEEL 1.5-INCH DIAMETER BOLTS THROUGH A 9.7-CM THICH LID FLANGE. THE LID SEAL IS PROVIDED BY A COMBINATION ELASTOMERIC-METALLIC SEAL. THE METALLIC SEAL IS RESPONSIBLE FOR PROVIDING THE NECESSARY LEAK TIGHTNESS WHILE THE ELASTOMERIC SEAL, WHICH IS LOCATED OUTBOARD TO THE METALLIC SEAL, PROVIDES AN ANNULAR TEST VOLUME THAT ENABLES LEAK TESTING OF THE METALLIC SEAL. TWO COVERED PORTS ON THE SIDE OF THE CASK BODY, EQUIPPED WITH TESTABLE SEALS, ARE PROVIDED FOR FILLING THE CASK CAVITY WITH HELIUM BEFORE TRANSPORT, FILLING THE CAVITY WITH WATER BEFORE UNLOADING OR LOADING CONTENTS. A PERMANENT REPAIR PLUG WAS THREADED AND SEAL-WELDED INTO THE CASK BODY AT THE UPPER PORT TO CORRECT A FABRICATION MACHINING ERROR THAT DAMAGED THE SEALING SURFACE. THIS PLUG FORMS A NEW SURFACE FOR THE UPPER DRAIN PLUG SEAL. A REMOVABLE BORE PLUG WAS ALSO ADDED TO THE UPPER PORT TO REDUCE THE UNEXPECTED RADIATION STREAMING. SEE CERTIFICATE**
