Embodiments of the present disclosure are directed to systems, components, and methods for transferring canisters containing radioactive material, for example, from a container assembly using a transfer assembly to a horizontal storage module (HSM). Systems in accordance with various embodiments of the present disclosure include, for example, a vertical to horizontal (VTH) transfer station for a canister and method of transfer, a horizontal to horizontal (HTH) transfer station for a canister and methods of transfer, a transport wagon system for transporting a canister to a horizontal storage module (HSM), and an HSM system for long-term storage of a canister.
1. A system for transferring a canister containing radioactive material from a cask to a horizontal storage module, the system comprising:
a transfer station for transferring the canister from the cask to a support structure; and
a transport conveyance for conveying the canister and the support structure in a horizontal orientation to a horizontal storage module and loading the canister and the support structure into the horizontal storage module;
wherein the transfer station includes a gantry platform for mating with the transport conveyance when in a vertical orientation, the gantry platform comprising a device for removing a lid on the cask to allow delivery of the canister from the cask.
2. The system of claim 1 , wherein the transfer station is a vertical to horizontal transfer station.
3. The system of claim 1 , wherein the transfer station includes an up-ender platform to move the transport conveyance to the vertical orientation for receiving the canister.
4. The system of claim 3 , wherein the transfer station includes a securement device for securing the transport conveyance on the up-ender platform.
5. The system of claim 1 , wherein the gantry platform guides a canister into the conveyance in the vertical orientation.
6. The system of claim 1 , wherein the gantry platform includes an aperture through which the canister is delivered.
7. The system of claim 1 , wherein the gantry platform includes a device for removing a door on the transport conveyance to allow insertion of the canister in the transport conveyance.
8. The system of claim 3 , wherein the up-ender platform is configured to move the transport conveyance from the vertical orientation back to a horizontal orientation.
9. The system of claim 1 , wherein the transfer station is a horizontal to horizontal transfer station.
10. The system of claim 9 , wherein the transfer station includes a roller stand.
11. The system of claim 9 , wherein the transfer station includes a lift assembly.
12. The system of claim 11 , wherein the lift assembly is a sling lift assembly.
13. The system of claim 1 , wherein the conveyance includes an actuation assembly for moving the canister and the support structure into the horizontal storage module.
14. The system of claim 1 , wherein the transport conveyance includes one or more transport conveyance devices.
15. The system of claim 14 , wherein the one or more transport conveyance devices are selected from the group consisting of wheels, tracks, rollers, bearing pads, bearing surfaces, air skids, and combinations thereof.
16. The system of claim 1 , wherein the transport conveyance includes outer walls.
17. The system of claim 16 , wherein the outer walls include shielding material for radiation containment.
18. The system of claim 1 , wherein the transport conveyance includes a transfer assembly for loading the canister and the support structure into the horizontal storage module.
19. The system of claim 18 , wherein the transfer assembly includes a jack assembly, one or more transfer conveyance devices, and a lateral extender.
20. The system of claim 19 , wherein the one or more transfer conveyance devices are selected from the group consisting of wheels, tracks, rollers, bearing pads, bearing surfaces, air skids, and combinations thereof.
21. The system of claim 18 , wherein the transfer assembly is hydraulically or electromechanically operated.
22. A system for transferring a canister containing radioactive material from a cask to a horizontal storage module, the system comprising:
a transfer station for transferring the canister from the cask to a support structure; and
a transport conveyance for conveying the canister and the support structure in a horizontal orientation to a horizontal storage module and loading the canister and the support structure into the horizontal storage module;
wherein the transfer station includes a gantry platform for mating with the transport conveyance when in a vertical orientation, the gantry platform comprising a device for removing a door on the transport conveyance to allow insertion of the canister in the transport conveyance.
23. A system for transferring a canister containing radioactive material from a cask to a horizontal storage module, the system comprising:
a horizontal to horizontal transfer station for transferring the canister from the cask to a support structure; and
a transport conveyance for conveying the canister and the support structure in a horizontal orientation to a horizontal storage module and loading the canister and the support structure into the horizontal storage module;
wherein the horizontal to horizontal transfer station comprises a sling lift assembly.
