| Savannah River Site Burial Ground | 193 | Solid waste stored in containers. Waste consists of many forms when packaged - nitrates, fluorides, oxides, and oxalates. Over time, the oxidizing conditions force the chemistry of the metals to their most stable form. At this time, the primary form of material in the containers is an oxide or a complex form involving oxygen. |
| 382 | Liquid waste in high level waste tanks. This material will eventually be converted to a glass form for long term storage. | |
| Los Alamos National Laboratory Burial Ground | 610 | Solid waste in various forms. |
| Nevada Test Site Burial Ground | 16 | Solid waste received from Rocky Flats Plant and Pantex Plant is stored in retrievable land burial or in above ground containers. |
| Argonne National Laboratory-West | 2 | Plutonium embedded in irradiated reactor test loops and reactor blanket assemblies stored in dry storage tubes underground. |
| Hanford Site | 455 | High level waste in the tank farms. |
| 875 | Solid waste in burial grounds. | |
| 192 | Waste in cribs, trenches and ponds. | |
| Oak Ridge National Laboratory | 41 | Particulate waste, as sediment in a settling basin, dry solids and oxides in above and below surface burial grounds, and solution and sludge in storage tanks. |
| Idaho, Waste Management | 1,026 | Solid waste in drums and boxes received primarily from Rocky Flats Plant is stored in above ground pads covered with earthen berms. |
| Idaho, Idaho Chemical Processing Plant Waste Farm | 8 | Solutions stored in tank farms. |
