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.

A model is developed to generate homogenized, two-group cross-section data for pressurized water reactor (PWR) fuel assemblies loaded with burnable absorbers by explicitly incorporating the effects of the neutron poison into the unpoisoned group constants. This provides the calculational freedom to use the assembly burnable absorber loading as an independent variable in dynamic search methods for optimizing low-leakage PWR core reloads. To achieve an accuracy of better than 0.2% in the assembly k∞, separate consideration is given to the absorption and scattering perturbations, as well as to the spectrum-hardening effects caused by the presence of burnable absorbers in the assembly. The model was validated first by comparison of unit assembly cross sections to data from reference calculations and then by use of the model in the Electric Power Research Institute nodal code SIMULATE-E and comparison to reference core power distributions.
