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.

Cement-based salt concrete (mass concrete with crushed salt filler) and MgO (sorel) concrete are the building materials used for seals in repositories in salt formations. These structures are important elements to prevent the access of aqueous solutions to emplaced waste containments. The post-closure evolution of such cements is studied in detail at GRS in order to understand the long-term changes in their hydraulic conductivity. This includes CHM-coupled interactions between the concrete material and the host rock and formation water. This paper presents results from laboratory investigations of the sealing capacity of seal systems at laboratory scale in contact with various saline solutions.
