The CNS is responsible for ensuring DOE Nuclear Safety Regulations, Standards, Guides, and national/international technical standards are applied.

The Office of Environmental Management (EM) sponsors science and technology development to improve the efficacy, effectiveness, and safety of its cleanup efforts.

As EM fulfills its mission, waste and materials disposition plays a vital role in the cleanup of radioactive waste.

Deactivation and Decommissioning (D&D) is the process of taking an active/excess/abandoned facility to a final disposition end state.

In fulfilling its mission, EM frequently manages and completes disposition of surplus nuclear materials and spent nuclear fuel.

Radiological shipments are accomplished safely. Annually, about 400 million hazardous materials shipments occur in the US by rail, air, sea, and land.

The Department of Energy is not a regulatory agency; however it does self-regulate its own radioactive waste.

The U.S. Department of Energy (DOE) manages one of the largest groundwater and soil remediation efforts in the world.

The Department has approximately 88 million gallons of liquid waste stored in underground tanks and approximately 4,000 cubic meters of solid waste.
