DOE on track to deliver high-burnup SNF to Idaho by 2027
The Department of Energy said it anticipated delivering a research cask of high-burnup spent nuclear fuel from Dominion Energy’s North Anna nuclear power plant in Virginia to Idaho National Laboratory by fall 2027. The planned shipment is part of the High Burnup Dry Storage Research Project being conducted by the DOE with the Electric Power Research Institute.
As preparations continue, the DOE said it is working closely with federal agencies as well as tribal and state governments along potential transportation routes to ensure safety, transparency, and readiness every step of the way.
Watch the DOE’s latest video outlining the project here.

The self-diffusion of 14C and 233U in four different uranium carbonitrides, UCxN1−x with x = 0.67, 0.26, 0.24, and 0.18, and the diffusion of 238Pu in two sets of (U,Pu)C0.8N0.2 were measured. Replacing carbon by nitrogen decreased self-diffusion rates in both metal and nonmetal lattices. The decrease was not linear with x; rather, a change in mechanism or bonding at around x ≈ 0.5 was indicated. The data are of importance for both fabrication and reactor operation of carbonitrides.
