The U.S. Department of Energy's Argonne National Laboratory is actively engaged in rebuilding Ukraine's clean energy infrastructure post-war, with a focus on small modular reactor applications. The collaboration stems from the U.S. Department of State's initiative known as the Foundational Infrastructure for the Responsible Use of Small Modular Reactor Technology (FIRST) Program, which aims to assist partner countries in exploring small modular reactors and advanced nuclear technologies while upholding safety and security standards. Recently, Ukraine joined the program and further participated in the Nuclear Expediting the Energy Transition (NEXT) sub-Program, receiving technical support for small nuclear reactors. During the 29th United Nations Climate Change Conference, the NEXT partnership was announced, with projects supported by a public-private consortium from Japan, Korea, Ukraine, and the U.S. Argonne's involvement includes projects to develop clean nuclear-generated hydrogen (Clean Fuels) and support clean steel production (Clean Steel) in Ukraine. These projects aim to enhance energy security, reduce carbon emissions, and integrate small modular reactors into various industries. By leveraging its expertise and longstanding partnership with Ukraine, dating back to the 1990s, Argonne is contributing to capacity building, technical assistance, and training programs for Ukrainian graduate students. The overall sentiment towards hydrogen and clean energy in the article is positive, emphasizing the potential benefits of small modular reactors in advancing energy security, resilience, and independence for Ukraine.
