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.

In concrete reactor vessels of high temperature reactors many cavities with different diameters are arranged. The design of the closures for such cavities is an important problem in the detail engineering. A draft based on using prestressed concrete as a material is presented for closures with high diameter values. The problems that could possibly be caused by the concrete weight might be solved through a proposal based on a separation of the closure into an inner and outer part. A special view is given to the kind of production as well as to a rapid mounting and remounting of the closures and sealing problems. The closures are fixed on the reactor vessel by tendons. The influence of the tendon forces, creep and shrinkage, pressure, etc. on stresses, stress distribution, and deformation are proved by a finite element analysis and the results are pointed out. A short outlook of further development is given.
