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 quantitative theory of angular truncation errors is developed for three-dimensional discrete-ordinates (SN) particle transport calculations. The theory is based on an analysis of a special problem: a localized radially symmetric source in an infinite homogeneous scattering medium, with an arbitrary scattering ratio c satisfying 0 < c < 1. For both the linear Boltzmann equation and the SN equations, we construct and compare analytic solutions of this problem that are asymptotically valid far from the source region. Comparing these analytic solutions, we find that the relative error in the SN solution increases without bound for large distances from the source region but decreases at each fixed spatial point as the scattering ratio or N (the order of the quadrature set) increases. Also, the SN error patterns conform to classic ray effects for small c but not for larger c. We present numerical results that test and validate the theoretical predictions.
