Horizontal storage module, carriage assembly, and canister transfer assemblies
A horizontal storage module (HSM) includes a body defining a plurality of compartments configured for receiving canisters, wherein the compartments are arranged in a first row at a first elevation and a second row at a second elevation higher than the first elevation, and wherein at least a portion of one compartment in the first row is in the same horizontal axis location as at least a portion of one compartment in the second row. A method of manufacturing the HSM includes positioning adjacent segments. A carriage assembly for the HSM includes a frame and an actuation means for lifting a cask containing a canister. A method of lifting includes receiving a cask and lifting a cask for delivery of the canister to the HSM.
1. A horizontal storage module (HSM) for storing a plurality of canisters containing a radioactive material, comprising:
a unitary body defining a plurality of compartments, each compartment configured for receiving one of the plurality of canisters, wherein the compartments comprise a first row of compartments at a first elevation and a second row of compartments at a second elevation higher than the first elevation, wherein the compartments are separated by dividing walls; and
a plurality of canister supports fixed to the dividing walls and configured to support the plurality of canisters centrally within a corresponding one of the plurality of compartments such that the canisters are spaced from the dividing walls and canisters in the first row of compartments do not overlap vertically with canisters in the second row of compartments;
wherein a lower portion of the second row of compartments are at a lower elevation than an upper portion of the first row of compartments.
2. The HSM of claim 1 , further comprising ventilation means in each of the plurality of compartments including vent paths having substantially vertical pathways.
3. The HSM of claim 1 , wherein each compartment is adjacent at least two other compartments.
4. The HSM of claim 1 , wherein each compartment is polygonal in cross-sectional shape.
5. The HSM of claim 1 , wherein the compartments are pentagonal in cross-section.
6. The HSM of claim 1 , wherein the plurality of compartments are arranged in a staggered configuration.
7. The HSM of claim 1 , further comprising a roof on the body.
8. The HSM of claim 7 , wherein the roof includes a plurality of outlet vents, wherein each outlet vent is in fluid communication with a corresponding one of the plurality of compartments.
9. The HSM of claim 7 , wherein the roof is supported only by a front wall of the body and a back wall of the body.
10. The HSM of claim 1 further comprising a plurality of airflow pathways, wherein each airflow pathway extends from a lower inlet vent to a corresponding one of the plurality of compartments and from the corresponding compartment to an upper outlet vent.
11. The HSM of claim 1 further comprising a carriage assembly for lifting the canister to the second elevation.
12. The HSM of claim 1 , wherein the body portion is modularized and made from a plurality of segments.
13. The HSM of claim 12 , wherein the plurality of segments are vertically layered on top of each other.
14. The HSM of claim 12 , wherein adjacent segments are attached to one another using only a vertical attachment system.
15. The HSM of claim 14 , wherein the vertical attachment system includes a plurality of vertically oriented holes in the walls of adjacent segments, and ties connecting such holes.
16. The HSM of claim 1 , wherein the canister supports comprise bearing blocks.
