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.

Experimental study on tritium retention in tungsten was conducted, in which samples were irradiated with MeV-energy H or He ions and deuterium concentration profiles were subsequently observed under deuterium-plasma exposure conditions. The results showed that the deuterium concentration was significantly increased by irradiation at 573 K due to production of hydrogen traps while it was not under irradiation below 400 K. In the latter case, however, the concentration was increased when the sample was heated around 550 K. The trap was considered to be a kind of interstitial defects and grown at 550 - 600 K from irradiation defects. Once produced, the trap was stable at least 710 K.
