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.

Experiments on the Omega laser at the Laboratory for Laser Energetics require tantalum oxide (Ta2O5) aerogel thin films with a thickness ranging from 70 to 150 m and densities of 250 and 500 mg/cm3. Experiments have been done with the aerogel in a disk geometry with diameters ranging from ~2 to 3 mm with annular slots machined into it and without the slots. These experiments place demanding specifications on the targets in terms of thickness, dimensionality, and mass density variation. Future radiation experiments at the National Ignition Facility will require larger targets ~7 mm in diameter and 200 m thick with more complex features. In the past these targets have been conventionally machined from a starting billet of aerogel ~5 mm in diameter and height. Through a series of steps the aerogel was eventually machined down to the desired thickness. This was a long and arduous labor-intensive process that had high attrition rates and an overall yield of ~50%. We have improved this process by developing a new fabrication technique involving casting the foam to the desired thickness and then laser processing to create the desired features. This technique yields targets that meet the demanding specifications used in recent experiments while increasing throughput, yield, and available feature complexity in targets.
