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.

An integrated Operator Advisor System (OAS) has been built using generic task methodology. The operator’s activities of plant monitoring, data interpretation, procedure execution, and diagnosis have been implemented as the four generic tasks in the system. The OAS is capable of identifying the abnormal functioning of the plant in terms of threats to safety, preenumerated abnormal events, and deviations from normality. After the identification of abnormal functioning, the system will identify the procedures to be executed to mitigate the consequences of abnormal functioning and will help the operator by displaying the procedure steps and monitoring the success of actions taken. The system also is capable of diagnosing the cause of abnormal functioning. The diagnosis is done in parallel to the task of procedure execution. The system is designed to operate in real time and can change its focus of attention depending on current priorities. The system also is designed to provide defense-in-depth in situations when there are no available procedures or the available procedures cannot be successful. The OAS has been tested with a scenario and a limited number of procedures for abnormal events and safety threats. The system responds as expected according to the procedures and knowledge incorporated in it.
