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.

The consequences of using three different interpolation methods for tabular neutron and photon energy distribution data are investigated. The three methods are linear interpolation on energy, linear interpolation on energy after the secondary energy ranges are transformed to unit base, and linear interpolation on energy after the initial distributions are converted to cumulative probability distributions by integration over the secondary neutron or photon energy. The latter two methods may subsequently be reconverted to differential probabilities. Linear interpolation on energy without transformation or conversion is shown to be the least desirable for most applications.
