Method of using a modular container system for radioactive waste
A packaging system for radioactive waste is robust, highly functional, and can be used for nearly all radioactive waste streams that require shielded packaging. The packaging system includes a modular container that is configured to receive modular shielding inserts. The packaging system can be used to store, transport, and dispose of radioactive waste.
1. A method comprising:
selecting a modular container to hold radioactive waste, the modular container being selected from a plurality of modular containers having different grades that differ structurally from each other to accommodate different activity levels of radioactive waste and/or containment requirements; and
positioning the radioactive waste in the modular container;
wherein the plurality of modular containers include at least one grade of modular container capable of accommodating containment requirements for at least Class B radioactive waste.
2. The method of claim 1 comprising positioning a support framework in the modular container, the support framework being configured to hold one or more sub-containers filled with the radioactive waste.
3. The method of claim 1 comprising positioning a liner configured to hold granular radioactive waste in the modular container.
4. The method of claim 1 comprising coupling a transport overpack to the modular container.
5. The method of claim 1 wherein each of the plurality of modular containers includes an enclosure envelope defining a cavity configured to receive the radioactive waste, and wherein the cavity defined by each enclosure envelope has a standardized size and shape.
6. The method of claim 1 wherein each of the plurality of modular containers includes a main body, and wherein the main body of one grade of the plurality of modular containers is made of carbon steel and the main body of another grade of the plurality of modular containers is made of stainless steel.
7. The method of claim 1 wherein the plurality of modular containers include at least one grade of modular container capable of accommodating containment requirements for at least Class C radioactive waste.
8. The method of claim 1 wherein the plurality of modular containers comprise at least three modular containers.
9. A method comprising:
selecting an enclosure envelope to hold radioactive waste, the enclosure envelope being selected from a plurality of modular enclosure envelopes having different grades that differ structurally from each other to accommodate different activity levels of radioactive waste and/or containment requirements; and
positioning the radioactive waste in the enclosure envelope;
wherein each of the plurality of modular enclosure envelopes defines a cavity configured to receive the radioactive waste; and
wherein the cavity defined by each of the plurality of modular enclosure envelopes has a standardized size and shape.
10. The method of claim 9 comprising positioning shielding inserts in the enclosure envelope, the shielding inserts being obtained from groups of modular shielding inserts where each group is a different grade of shielding inserts having different thicknesses and/or being made of different material to accommodate different activity levels of radioactive waste.
11. The method of claim 10 wherein the shielding inserts are not joined together prior to being positioned in the enclosure envelope and are rendered to a structurally stable configuration after being positioned in the enclosure envelope.
12. The method of claim 9 comprising positioning a liner configured to hold granular radioactive waste in the enclosure envelope.
13. The method of claim 9 comprising positioning a support framework in the enclosure envelope, the support framework being configured to hold one or more sub-containers filled with the radioactive waste.
14. The method of claim 9 comprising coupling a transport overpack to the enclosure enveloped.
15. The method of claim 9 wherein the plurality of modular enclosure envelopes comprise at least three modular enclosure envelopes.
16. The method of claim 9 wherein each one grade of enclosure envelope from the plurality of modular enclosure envelopes is made of carbon steel and another grade of enclosure envelope from the plurality of enclosure envelopes is made of stainless steel.
17. The method of claim 9 wherein the plurality of enclosure envelopes include at least one grade of enclosure envelope capable of accommodating containment requirements for at least Class B radioactive waste.
18. The method of claim 9 wherein the plurality of enclosure envelopes include at least one grade of enclosure envelope capable of accommodating containment requirements for at least Class C radioactive waste.
19. A method comprising:
selecting a modular container to hold radioactive waste, the modular container being selected from a plurality of modular containers having different grades that differ structurally from each other to accommodate different activity levels of radioactive waste and/or containment requirements;
positioning shielding inserts in the modular container, the shielding inserts being obtained from groups of modular shielding inserts where each group is a different grade of shielding inserts having different thicknesses and/or being made of different material to accommodate different activity levels of radioactive waste; and
positioning the radioactive waste in the modular container.
20. The method of claim 19 comprising positioning a liner configured to hold granular radioactive waste in the modular container.
21. The method of claim 19 comprising positioning a support framework in the modular container, the support framework being configured to hold one or more sub-containers filled with the radioactive waste.
22. The method of claim 19 comprising coupling a transport overpack to the modular container.
23. The method of claim 19 wherein each of the plurality of modular containers includes an enclosure envelope defining a cavity configured to receive the radioactive waste, and wherein the cavity defined by each enclosure envelope is approximately the same size.
24. The method of claim 19 wherein each of the plurality of modular containers includes a main body, and wherein the main body of one grade of modular container from the plurality of modular containers is made of carbon steel and the main body of another grade of modular container from the plurality of modular containers is made of stainless steel.
25. The method of claim 19 wherein the plurality of modular containers include at least one grade of modular container capable of accommodating containment requirements for at least Class B radioactive waste.
26. The method of claim 19 wherein the plurality of modular containers include at least one grade of modular container capable of accommodating containment requirements for at least Class C radioactive waste.
27. The method of claim 19 wherein each of the plurality of modular containers defines a cavity configured to receive the radioactive waste, and wherein the cavity defined by each of the plurality of modular containers has a standardized size and shape.
28. The method of claim 19 wherein the plurality of modular containers comprise at least three modular containers.
