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.

The main objectives of a TRISO treatment are to effectively breach and separate the carbon and SiC layers composing the TRISO particles. The reported technologies used to treat a spent TRISO fuel are almost identical, involving a final wet chemical process under which crushed TRISO fuel is processed to separate the coating layer fines from the kernel. Also, these processes are mainly powder processes with a secondary waste generation, and they require a corrosive solution as well as complex processing steps.Hence, two innovative processing concepts are proposed in this investigation; namely, a thermal shock and a pyrochemical process to breach the coating layers of the TRISO particle with a minimal amount of secondary waste. The preliminary results showed that the chemical vapor deposition (CVD) SiC layers, as pseudo coating layers of the TRISO fuel, exhibited very robust thermal shock behaviors even at 1300°C of T, but a cyclic thermal shock caused a drastic degradation of their hardness. Also, it was confirmed that the CVD SiC as well as the glassy carbon rod can be breached by a chemical reaction in a molten salt with Mg and Li, respectively. Therefore, the proposed technologies are found to be very promising for treating a spent TRISO fuel without a considerable generation of secondary wastes.
