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.

Laboratory experiments showed that neptunium hexafluoride is sorbed more effectively by sodium fluoride at 200°C than by the fluorides of lithium, magnesium, and calcium at 100 to 400°C. The equilibrium pressure of NpF6 over the complex formed with sodium fluoride in the presence of fluorine was measured. A sorption-desorption method based upon the difference in equilibrium pressures of the hexafluorides of neptunium and uranium over the sodium fluoride complex does not appear to be useful for separating neptunium hexafluoride from uranium hexafluoride at neptunium: uranium weight ratios that usually exist in spent nuclear fuels. However, favorable results were obtained with a method that involves cosorbing the neptunium and uranium hexafluorides, reducing the neptunium in the NpF6-NaF complex, desorbing the uranium, and refluorinating and desorbing the neptunium. The development of the latter method is described, and the inherent problems and the effects of variables are discussed.
