Radioactive Waste Disposal
The Nevada National Security Site plays a pivotal role in the cleanup of historic nuclear weapons sites in the United States by
providing a safe and environmentally-effective facility for the permanent disposal of low-level and mixed low-level
radioactive waste. The waste disposed at the Nevada National Security Site is accepted only from approved U.S. Department of Energy
and U.S. Department of Defense sites and must comply with the Nevada National Security Site Waste Acceptance Criteria.

Low-Level Radioactive Waste
Typical low-level waste includes materials such as rags, papers, filters, equipment, discarded protective clothing and
construction debris. Low-level waste does not include high-level waste, spent nuclear fuel, transuranic waste, or
radioactive by-product materials.
Mixed Low-Level Radioactive Waste
Mixed low-level radioactive waste contains both hazardous waste, as defined by the Resource Conservation and Recovery Act (RCRA),
and low-level radioactive waste. As a result of the presence of the hazardous component, mixed low-level radioactive waste is
regulated and managed separately from low-level radioactive waste. This waste is disposed in the Mixed Waste Disposal Unit at the
Nevada National Security Site Area 5 Radioactive Waste Management Site. The Mixed Waste Disposal Unit is RCRA-permitted and
features a multi-layer liner and collection system that drains any potential moisture away from the buried waste containers. This
technologically advanced cell became operational in December 2010 and replaces the previous mixed low-level waste disposal cell
which closed on November 30, 2010.

In addition to disposal, mixed low-level waste may be stored at the Area 5 Radioactive Waste Management Site in accordance with a
separate RCRA permit.
