Advising DOE on Safely Disposing of its Solid Nuclear Waste
Idaho National Laboratory, Multiple Sites
DOE sites routinely generate, process, and store solid nuclear wastes. In recent years, DOE experienced two significant events—one in 2014 at Waste Isolation Pilot Plant and another in 2018 at Idaho National Laboratory — in which waste drums released radiological materials due to energetic chemical reactions involving the waste.
Managing Risks of Flammable Gases in Waste Containers
Our Work
Some nuclear waste drums at Idaho National Laboratory contain gases that can burn, which could potentially expose workers to radiological waste released from the drum. DNFSB has reviewed the implementation of applicable safety requirements and standards to ensure these risks are being adequately managed.
Our Safety Impact
DOE has made many improvements to the safe storage of solid nuclear waste because of advice and guidance from the DNFSB including installing new controls, such as lid restraints on drums with elevated flammable gas hazards at the Idaho National Laboratory.

Analyzing Chemical Reactions involving Nuclear Waste
Our Work
DOE depends on its solid radioactive waste to be benign and unreactive as it awaits permanent disposal. DNFSB has reviewed the storage, handling, and processing of this waste at sites across the DOE defense nuclear complex.
Our Safety Impact
DNFSB's technical advice has strengthened DOE’s processes to ensure the waste is safe while it awaits final disposal.
