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.

This paper describes the uptake of plutonium, 238Pu, by an adsorbent consisting of Brimac 216 natural carbon, a type of bone char. A strongly magnetic Brimac 216 fine powder produced by Lidzey has been shown to be an excellent adsorbent for many radionuclides. After the adsorption of the radionuclides has taken place, from solution onto the magnetic Brimac 216 powder, the powder, together with the adsorbed radionuclides, can be rapidly removed from suspension, as a concentrate, using high gradient magnetic separation (HGMS). A comparison is drawn between experimental results using the conventional column filter, with bone char as the adsorbent medium, and calculations for the HGMS process to treat 3.22 m3 of solution containing 8 mgl-1 of 238Pu and to remove the 238Pu from the suspension to reduce the effluent to less than the maximum concentration limit (MCL) for 238Pu, which is 0.74 Bql-1; however, the minimum concentration value used here is less than the MCL and is 0.0444 Bql-1 (7.006 × 10-14 gl-1 of 238Pu) and is denoted as the lower concentration level. Calculations indicate that HGMS is considerably faster than the column filtration method. This leads to a significant reduction in the time required to process the solution, even though the HGMS process is repeated a number of times. Also, the mass of adsorbent requiring long-term storage is much smaller for HGMS than for the column filtration method.
