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.

High-power negative and positive ion-based neutral beam injectors (NBIs) are operated with high reliability in the Large Helical Device (LHD). The total injection power is >20 MW, and such high-power beams are available every 3 min. The high performance of the LHD NBI system has extended the LHD parameter regime to levels equivalent to those obtained in large tokamaks. Three negative NBIs inject a total power of 16 MW with an energy of 180 keV, which is the world's highest power from a negative NBI system (H-), and one positive NBI (H+) injects 7 MW at 40 keV. The injection duration can be extended beyond 1 min with reduced power from the negative and positive NBIs, and long-pulse plasmas are successfully sustained with the NBIs. The structure and performance of the LHD NBI system is reviewed.
