Testing is underway at an electric-powered microreactor prototype developed by the US Department of Energy (DOE). The 12-foot-tall machine is a full-scale replica of the Department’s Marvel microreactor, which is being built to advance new reactor technologies. Marvel will be the first new reactor at Idaho National Laboratory (INL) in more than four decades and is aiming to be operational in 2025.

The recently opened Gayle & Max Dillard Science & Engineering Research Centre (SERC) at the US Abilene Christian University (ACU) in Texas, which includes the Nuclear Energy eXperimental Testing Laboratory (NEXT Lab), is continuing to pursue research on molten salt reactors. “The Dillard Science and Engineering Research Centre is a building unlike any other at ACU or on the campus of most universities across the nation,” said Phil Schubert, ACU president, at the opening of the facility.

US-based X-Energy Reactor Company and the US Department of Defense (DOD) have agreed to expand the contract under the Project Pele initiative to develop a transportable, cost-effective advanced nuclear microreactor prototype for use in remote military locations. X-energy said it expects to advance the design of its prototype – which could also be used for commercial or industrial use in civilian applications – through an award of $17.49m within the existing DOD contract. This will be a second design to be developed under Project Pele.

A US Department of Energy (DOE) report has suggested pairing advanced reactors with carbon dioxide removal technologies, including direct air capture. DOE says advanced reactors could lower the levelised cost of certain direct air capture technologies by up to 13% compared with non-nuclear-powered systems. This could also boost reactor performance and market feasibility.

The US Department of Energy (DOE) is working to recycle used fuel from the closed EBR-II reactor to make high-assay low-enriched uranium (HALEU) which is required by most advanced reactors designs. HALEU, enriched between 5% and 19.75% with uranium-235, is not currently available from domestic suppliers
