The hazardous characteristics of the MLLW are expected to be quite diverse and will include a combination of metals without mercury and organics, a combination of corrosives, metals, state regulated, and organics, as well as other characteristics. The majority of TRUM waste will contain a combination of metals and organics, with state regulated and metals making up the rest of the waste.

Solid waste is generated on an ongoing basis during research and decontamination activities.
Operational and clean-out waste generated prior to transitioning facilities from PNNL are included. The forecast assumes that some of the LLW will be compacted at ATG prior to disposal, and that the MLLW will be treated prior to shipment. Waste streams held at the Pacific Northwest National Laboratory with no defined disposal pathway were not included in the forecast. These waste streams include fuel-like material stored in the 325 facility hot cells. When disposal pathways are identified for these waste streams, they will be included as an update to this forecast.
