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.

Beryllium is being considered as a possible capsule material for ignition targets for the National Ignition Facility. The material and machining specifications may ned to be highly restrictive, especially with regard to isotropic sound propagation. Beryllium, a hexagonal metal, displays directionally dependent sound speeds due to its anisotropic Young’s modulus. Crystallographic texture transfers this anisotropic sound speed to the polycrystal to varying degrees depending on the texture strength. From published values for the elastic compliances for Be, the value of E for single crystals was seen to vary with azimuthal angle from the c axis, from about 350 GPa parallel to c to about 290 GPa parallel to a. The longitudinal sound velocity varies with E, and experimentally measured velocities on single crystal Be are in good agreement with the derived values. The value of E for polycrystalline Be was calculated from simulated textures ranging from 1 MRD (multiples of random distribution), i.e., random, to 2, 4, 8, 20, and 40 MRD. The difference in sound speed from the fastest to the slowest direction for those textured materials were 0, 0.5, 1.0, 1.9, 3.8, and 5.4 percent respectively. Experimentally measured textures, processed by hot-pressing, swaging, and HIPping, were used to illustrate the effect of process variables on the resulting texture. These types of differences in sound speed have tremendous implications for the manner in which the beryllium used for ignition capsules for the National Ignition Facility is fabricated.
