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 Instrumented Subassembly System supplies the means of measuring operating parameters of specimen fuels, instruments, and related components in the EBR-II core. The system consists of an instrumented subassembly, an extension tube with seals and connections for the instrument lead wires, a drive to make it compatible with fuel handling operations, and recording and data logging equipment. The instrumented subassembly is located in the fifth row of the core (replacing a control rod), is cooled by flowing sodium of 700 to 900°F, and is exposed to a total flux of ∼ 1.9 × 1015 n/(cm2 sec) at 50-MW reactor power. A prototype subassembly, containing 23 instruments was successfully tested in the reactor for 140 days (3856 MWd).
