Waste is generally categorized as high level waste (HLW) and low-level waste (LLW). LLW contains materials such as irradiated tools, lab clothing, ion exchanger resins, animal carcasses, and trash from defense, commercial nuclear power, medical, and research activities. [1]

LLW in the United States is defined as nuclear waste that does not fit into the categorical definitions: high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or certain byproduct materials known as 11e(2) wastes, such as uranium mill tailings.
Intermediate-level waste (ILW) contains higher amounts of radioactivity compared to low-level waste. It generally requires shielding, but not cooling. [ 40 ] Intermediate-level wastes includes resins , chemical sludge and metal nuclear fuel cladding, as well as contaminated materials from reactor decommissioning.

A U.S. appeals court on Friday canceled a license granted by a federal agency to a company to build a temporary nuclear waste storage facility in western Texas, which the Republican-led state has ...
The vitrification plant is planned to treat all the high-level radioactive waste in the tanks and much of the low activity waste. About 90% of the waste to be treated is low activity waste.
In the late 1990s, the Texas Low-Level Radioactive Waste Disposal Authority proposed a nuclear waste site near Sierra Blanca. [31] The waste site was thought to bring an economic boost to the town. This proposal was eventually declined, citing concerns about the site being in the most seismically active region of Texas. [32]
Holtec proposed to build a facility to temporarily store spent nuclear fuel rods at the site on the surface, ultimately with a capacity to hold up to 100,000 metric tons of the waste brought into ...
