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 prototype on-line reactivity meter using reactor noise analysis techniques is based on a two-detector cross correlation method, which offers as a special feature the absence of uncorrected noise contribution to the spectral density function of the reactor system. Reactivity shutdown measurements were performed on three different zero power reactors down to seven dollars. Special attention is given to the predicted and measured error margins of reactivity. The described on-line meter, when used with optimized current type neutron detectors for minimum gamma contamination, promises to be an encouraging way of making shutdown reactivity measurements, perhaps also in “dirty” power reactors where the high gamma-ray intensities can considerably destroy the “clean neutron signal-to-noise” ratio.
