1. A system for translating high level radioactive waste across a ground surface, the system comprising:a cask loaded with high level radioactive waste;an apparatus comprising:a support assembly comprising:a lowermost surface; anda body having a cavity having an open top end; anda plurality of rollers coupled to the body, each of the rollers being translatable along a vertical axis between: (1) an extended position in which the plurality of rollers contact the ground surface and support the support assembly above the ground surface; and (2) a retracted position in which the plurality of rollers do not contact the ground surface and the lowermost surface of the support assembly contacts the ground surface; andthe cask positioned in the cavity, with a bottom surface of the cask positioned within the cavity, the cask supported above the ground surface by the lowermost surface of the support assembly when the plurality of rollers are in the extended position;wherein the support assembly further comprises at least one support member, each support member comprising a contact member coupled to the body and extending into the cavity, the cask positioned atop and in contact with the contact member;wherein each support member further comprises at least one support plate coupling the contact member to the body; andwherein the lowermost surface of the support assembly comprises the at least one support plate of each support member. 2. The system of claim 1 wherein a lower portion of the cask nests within the cavity of the body and an upper portion of the cask protrudes from the open top end of the cavity. 3. The system of claim 2 wherein the open top end of the cavity is formed in a top surface of the body. 4. The system of claim 1 wherein the cavity has a circular transverse cross-section and the cask has a circular transverse cross-section, and wherein an annular clearance exists between a lower portion of the cask that is located within the cavity and the body. 5. The system of claim 1 further comprising rails on the ground surface along which the plurality of rollers can translate when in the extended position. 6. The system of claim 1 wherein the cask comprises a plurality of cutouts in a bottom surface of the cask and the support assembly further comprises a plurality of support members, each support member comprising a contact member coupled to the body, and wherein each contact member nests within one of the cutouts and engages the cask. 7. The system of claim 1 wherein the lowermost surface of the support assembly comprises a plate. 8. The system of claim 7, wherein the lowermost surface of the support assembly comprises a planar surface of the plate. 9. A system for translating high level radioactive waste across a ground surface, the system comprising:a cask loaded with high level radioactive waste;an apparatus comprising:a body having a cavity having an open top end;at least one support member coupled to the body; anda plurality of rollers coupled to the body, each of the rollers being adjustable between: (1) an extended position in which the plurality of rollers contact the ground surface and support the body above the ground surface; and (2) a retracted position in which the plurality of rollers do not contact the ground surface and the at least one support member contacts the ground surface;a lower portion of the cask positioned in the cavity so that the cask contacts and rests atop the at least one support member and is above the ground surface, an upper portion of the cask protruding from the open top end of the cavity. 10. The system of claim 9 wherein the cavity extends along a substantially vertical axis, the body comprising a wall surface that circumferentially surrounds the substantially vertical axis. 11. The system of claim 9 wherein the cavity has a transverse cross-section having a closed geometry. 12. The system of claim 9 wherein the cask extends along a longitudinal axis, the cask supported by the apparatus so that the longitudinal axis is substantially vertical. 13. The system of claim 9 wherein an annular clearance exists between the lower portion of the cask and the body. 14. The system of claim 9 further comprising rails on the ground surface along which the plurality of rollers can translate. 15. The system of claim 9 wherein the cask is supported by the apparatus so that a bottom surface of the cask is a distance between 0.1 to 6 inches above the ground surface. 16. The system of claim 9, wherein each support member comprises a plate, and when the plurality of rollers are in the retracted position, the plate contacts the ground surface. 17. The system of claim 16, wherein each plate comprises a planar surface, and when the plurality of rollers are in the retracted position, the planar surface of each plate contacts the ground surface. 18. A system for translating high level radioactive waste across a ground surface, the system comprising:a cask loaded with high level radioactive waste;an apparatus comprising:a body having a cavity having an open top end; anda support member disposed on the body and comprising a plate assemblage;a plurality of rollers coupled to the body, each of the rollers being translatable along a vertical axis between: (1) an extended position in which the plurality of rollers contact the ground surface and support the body above the ground surface; and (2) a retracted position in which the plurality of rollers do not contact the ground surface and the plate assemblage contacts the ground surface;the cask supported by the apparatus above the ground surface so that a lower portion of the cask is positioned within the cavity on the plate assemblage and an upper portion of the cask protrudes from the open top end of the cavity. 19. The system of claim 18 wherein the cavity has a transverse cross-section having a closed geometry. 20. The system of claim 18 wherein the cavity extends along a substantially vertical axis, the body comprising a wall surface that circumferentially surrounds the substantially vertical axis; wherein the cask extends along a longitudinal axis, the cask supported by the apparatus so that the longitudinal axis is substantially vertical; and wherein an annular clearance exists between the lower portion of the cask and the body. 21. The system of claim 18, wherein the plate assemblage comprises at least one lower plate, and when the plurality of rollers are in the retracted position, the at least one lower plate contacts the ground surface. 22. The system of claim 21, wherein each lower plate comprises a planar surface, and when the plurality of rollers are in the retracted position, the planar surface of each lower plate contacts the ground surface.
