I claim: 1. A reusable container for hazardous material, said container having high impact resistance and leak containment characteristics and being readily handleable by conventional fork lift or the like equipment, said container having a longitudinal axis and comprising a substantially closed and continuous first wall means providing an inner containment vessel for said material and having an open top portion, a substantially closed and continuous second wall means providing a protective shell substantially surrounding said vessel and having inner side surface portions radially outwardly spaced from at least a major portion of outer surface portions of said vessel to provide a first protective spacing between said vessel and shell, an access port formed thru said second wall means at a top section thereof, said open top portion of said vessel being affixed to said top section of said second wall means which places said access port in direct communication with said open top portion for loading and unloading said vessel with said material, a vessel cover adapted to be removably affixed to said top section to sealingly cover said access port, third wall means providing a sealable drum having side portions, a bottom, an open top, and sealable drum lid means for closing said open top, wherein said protective shell has from four to eight generally longitudinally extending strengthening rib means affixed to and substantially equidistantly spaced around and welded to segments of said outer surface portions of said shell and extending generally longitudinally thereof substantially from the top to the bottom of said shell, whereby said outer surface portions of said shell are spaced from inner surface portions of said drum side over a major portion of said drum to provide a second protective spacing between said drum and shell, wherein the construction of said second wall means provides a generally cylindrical upper side wall portion which extends longitudinally upward beyond said top section to provide a third protective spacing, wherein said upper side wall portion is provided at its top with a ring member which is affixed to an upper inner surface portion of said side portion of said drum, and wherein protective material is provided in said spacings. 2. The container of claim 1 wherein said rib means and inner surface portions of said drum are dimensioned to allow said shell to be slid down into said drum with said rib means positioned closely adjacent said inner surface portions of said drum. 3. The container of claim 1 wherein said inner surface portions of said drum are substantially cylindrical in configuration. 4. The container of claim 3 wherein said drum is a conventional fifty five gallon ring ribbed steel drum. 5. The container of claim 1 wherein said ring member comprises a heavy steel circular rim welded to said upper side wall portion of said shell and to an upper inner surface portion of said drum. 6. The container of claim 1 wherein the protective material in said first and third protective spacings comprises foamed polyurethane, and the protective material in said second protective spacing comprises ceramic fiber blanket. 7. The container of claim 6 wherein the density of said polyurethane foam is from about 5.0 PCF (pound per ft.3) to about 7.0 PCF. 8. The container of claim 1 wherein said rib means are tied together by a weld joint in a circular array to a reinforcing ring structure. 9. A reusable container for transporting radioactive or other potentially dangerous material and having a longitudinal axis and comprising an outer casing having a side wall, a bottom, an open top, and a lid means for sealing said open top, an intermediate shell having a side wall, a floor and an open top, said side walls being spaced radially inwardly from each other to form therebetween an outer protective cavity and to form within said shell an inner protective cavity, a material containment structure within said inner protective cavity and affixed to said side wall of said shell and providing a containment vessel having a top access port for allowing loading and unloading of said material into and from said vessel, removable cover means adapted for sealing said access port, said containment structure being spaced downwardly from said open top of said casing to form an upper protective cavity, impact and heat resistant protective material substantially filling said cavities, and from four to eight generally longitudinally extending rib means circumferentially and substantially equidistantly spaced around the periphery of said side wall of said shell within said outer protective cavity and affixed by welding to said side wall of said shell. 10. The container of claim 9 wherein said protective material in said upper protective cavity is in the form of a polymeric plug which can be slid out thru said open top of said casing for allowing unloading and reloading of said vessel thru said access port. 11. The container of claim 10 wherein said rib means and inner surface portions of said drum are dimensioned to allow said shell to be slid down into said drum with said rib means positioned closely adjacent said inner surface portions of said drum, and wherein upper portions of said shell are affixed to said drum. 12. The container of claim 10 wherein said inner surface portions of said drum are substantially cylindrical in configuration. 13. The container of claim 12 wherein said drum is a conventional fifty five gallon ring ribbed steel drum. 14. The container of claim 10 wherein said ring member comprises a heavy steel circular rim welded to said upper side wall portion of said shell and to an upper inner surface portion of said drum. 15. The container of claim 10 wherein the protective material in said upper protective cavity comprises foamed polyurethane, and the protective material in said outer protective spacing comprises ceramic fiber blanket. 16. The container of claim 15 wherein the polyurethane foam density is from about 5.0 PCF (pound per ft.3) to about 7.0 PCF. 17. The container of claim 10 wherein said rib means are tied together by a weld joint in a circular array to a reinforcing ring structure.
