Keeping Waste Where It Belongs: Grain Size Explains How Spent Nuclear Fuel Enters the Environment
When compounds in spent nuclear fuel break down, they can release radioactive elements into the ground and water. Scientists know that one fuel compound, neptunium dioxide, reacts with water, but they do not fully understand the process. This new study found that neptunium tends to dissolve where grains of the material come together, and larger grains are less likely to dissolve.
Canister Delivery to Strengthen Nuclear Storage Research
Three unused, 48,000-pound stainless steel canisters arrived at PNNL, bringing the chance to deepen research in spent nuclear fuel storage and transportation.
Exploring Oxidative Pathways in Nuclear Fuel
An international team used PNNL microscopy to answer questions about how uranium dioxide—used in nuclear power plants—might behave in long-term storage.
