b'High-level waste (HLW)HLW is essentially the waste products generated as the byproduct of reprocessing spent nuclear fuel using methods developed more than 60 years ago. This reprocessing ended in 1992. In Idaho, the waste products were solidified and stored on-site in anticipation of a repository.Transuranic waste (TRU)Most TRU waste was generated from U.S. nuclear weapons production, mostly at Rocky Flats, Colorado, and is contaminated with elements heavier than uranium. INL received the weapons production waste from the Rocky Flats Plant from 1954 until 1989; it is sent for permanent geologic disposal at the Waste Isolation Pilot Plant outside of Carlsbad, New Mexico. INL research programs also generate TRU waste.Low-level waste (LLW)LLW is radioactive waste that is not high-level radioactive waste, spent nuclear fuel, transuranic waste, byproduct material (as defined in the Atomic Energy Act of 1954), or naturally occurring radioactive material. A common misperception is that LLW means low radioactivity. That isnt always the case. For'
