DOE’s latest fusion energy road map aims to bridge known gaps
The Department of Energy introduced a Fusion Science & Technology (S&T) Roadmap on October 16 as a national “Build–Innovate–Grow” strategy to develop and commercialize fusion energy by the mid-2030s by aligning public investment and private innovation. Hailed by Darío Gil, the DOE’s new undersecretary for science, as bringing “unprecedented coordination across America's fusion enterprise” and advancing President Trump’s January 2025 executive order, on “Unleashing American Energy,” the road map echoes plans issued by the DOE’s Office of Fusion Energy Sciences (FES) in 2023 and 2024, with a new emphasis on the convergence of AI and fusion.
The road map release coincided with other fusion energy events held this week in Washington, D.C., and beyond.

Neutron albedo methods can be used to simplify transport calculations in a wide variety of applications. Their utilization requires a collection of albedo data and a model which makes these results convenient for hand or machine computation. Results are presented here from neutron albedo calculations for incident intermediate-energy neutrons. These results can be explained using our knowledge of neutron interaction physics. Total albedos are directly related to the cross sections for elastic scatter and absorption. Angular distributions of reflected neutrons are approximately cosθr for all incident neutron conditions. The total albedo results are well modeled by an extension of a previously developed fast-neutron albedo model when ∑abs/∑t (the ratio of absorption to total cross section) is small.
