Late last week saw two announcements from companies working to recycle used nuclear fuel on a commercial scale, providing welcome news to anyone hoping to see the United States move to unlock the hidden potential of the more than 94,000 metric tons of spent fuel stored at power plant sites around the country.
Specialized loading equipment for TRUPACT-IIIs is sent from SRS to the Idaho Cleanup Project for reuse. (Photo: DOE)
Demonstrating the beneficial reuse of equipment among Department of Energy cleanup sites, the DOE’s Office of Environmental Management transferred TRUPACT-III shipping equipment from its Savannah River Site in South Carolina to the Idaho Cleanup Project at the Idaho National Laboratory Site. This collaboration shows how DOE-EM drives efficiency, focusing on priorities and reining in costs without sacrificing safety or effectiveness, the DOE said.

Holtec International has submitted a license termination plan (LTP) for Oyster Creek nuclear power plant to the Nuclear Regulatory Commission, a milestone in the decommissioning of the boiling water reactor, which operated from 1969 to 2018. Holtec took over Oyster Creek’s license from Exelon Generation in 2019 for the immediate decommissioning of the plant, located in Forked River, N.J.
The Mont Terri Rock Laboratory in Switzerland.
A new study, “Building Confidence in Models for Complex Barrier Systems for Radionuclides,” highlights a breakthrough in the modeling and simulation of underground nuclear waste interactions. Led by Massachusetts Institute of Technology Ph.D. student Dauren Sarsenbayev, assistant professor and ANS member Haruko Wainwright, and scientists Christophe Tournassat and Carl Steefel, the research shows how cutting-edge, high-performance computing simulations closely align with real-world experimental data from the Mont Terri underground laboratory in Switzerland. The alignment enhances confidence in the long-term safety of geological nuclear waste repositories.
