MODEL 5320: A DOME-TOPPED UPRIGHT CYLINDER MOUNTED ON A BASEPLATE SUPPORTED BY CASTERS. THE MAXIMUM WEIGHT OF THE PACKING PLUS PAYLOAD IS APPROXIMATELY 148.3 KG (327 LB.), AND NOMINAL HEIGHT EXCLUDING CASTERS AND MOUNTING PLATES IS 82.9 CM (32.65 IN.). INCLUDING CASTERS AND MOUNTING PLATE, THE OVERALL HEIGHT IS APPROXIMATELY 95.3 MC (37.5 I.). EXCLUDING THE BASEPLATE, THE LARGEST DIAMETER IS 19.3[sic] CM (16.75 IN.). THE BASELATE IS 45.7 CM (18 IN.) BY 50.8 CM (20 IN.). THE PACKAGING PAYLOAD VOLUME HAS A NOMINAL LENGTH OF 37.0 CM (14.58 IN.) AND A DIAMETER OF 4.4 CM (1.74 IN.). THE CONTENTS OF THE PACKAGE (NORMALLY HANDLED IN THE EP-60 PRODUCT CANISTER) ARE SEAL-WELDED INTO THE REMOVABLE STAINLESS STEEL PRIMARY CONTAINMENT VESSEL (PCV). STAINLESS STEEL HONEYCOMB MATERIAL IS USED TO LOCATE THE PCV AXIALLY WITHIN THE SCV AND TO ABSORB ENERGY ASSOCIATED WITH IMPACT ACCIDENTS. THE STAINLESS STEEL SECONDARY CONTAINMENT VESSEL (SCV) HAS A REMOVABLE BOLTED CLOSURE LID. THE FLANGE OF THE SCV HAS CONCENTRIC BUNA-N(TM) O-RING AND FLEXITALLIC(TM) GASKET SEALS THAT SATISFY THE CONTAINMENT REQUIREMENTS FOR NORMAL CONDITIONS OF TRANSPORT (NCT) AND HYPOTHETICAL ACCIDENT CONDITIONS (HAC), RESPECTIVELY. A FINNED ALUMINUM SHIELD TANK SURROUNDS THE NESTED PCV AND SCV. THE TANK IS FILLED WITH WATEREXTENDED POLYESTER (WEP) NEUTRON SHIELDING MATERIAL. THE SCV IS RETAINED WITHIN THE INNER SHELL OF THE SHIELD TANK BY A BOLT THAT FASTENS THE BOTTOM OF THE VESSEL TO THE BASEPLATE. HEAT FROM THE PACKAGE CONTENTS IS CONDUCTED TO THE OUTER SHELL OF THE SHIELD TANK BY RADIAL ALUMINUM WEBS THAT CONNECT THE INNER SHELL TO THE OUTER SHELL. AXIAL FINS ON THE OUTER SHELL DISSIPATE THE HEAT TO THE ENVIRONMENT. A STEEL PERSONNEL SCREEN ENCLOSES THE FINS AND PREVENTS PERSONNEL CONTACT DURING HANDLING OPERATIONS. A THERMAL SHIELD PROTECTS THE CLOSURE LID, FLANGES, CLOSURE BOLTS, AND SEALS OF THE SCV DURING THERMAL ACCIDENT CONDITIONS. A "TOP HAT" STYLE IMPACT LIMITER PROTECTS ALL OF THESE COMPONENTS DURING IMPACT ACCIDENTS. THE CASTERS UNDER THE BASEPLATE ELIMINATE THE NEED FOR LIFTING APPARATUS AND PERMIT MANUAL LOADING AND OFFLOADING TOLFROM THE TRANSPORT VEHICLE. *SEE CERT.
