Ampera Partners with Lawrence Livermore National Laboratory on Nuclear Fuel

The project focuses on optimizing the manufacturing of highly uniform, spherical thorium-232 kernels. Researchers will utilize droplet-based liquid-metal-jetting to refine particle production, drawing on previous prototypes developed by the laboratory. The scope of the work spans computational modeling, high-temperature process development, and rigorous material testing to ensure the scalability of the fuel production process.

Dr. Viktor Sukhotskiy, a principal investigator at the laboratory, noted that the initiative serves the dual purpose of solving complex nuclear fuel challenges while maturing liquid metal jetting as a manufacturing method. For Ampera, the collaboration is a critical step in vertically integrating its fuel supply. CEO Brian Matthews stated that developing this domestic capability is foundational to reducing cost and supply-chain risks for the company’s subcritical energy platforms.

Ampera’s proprietary technology portfolio, which includes over 60 patents, centers on compact reactors capable of operating for up to 30 years without refueling. These subcritical systems rely on an external neutron source for operation, a design intended for industrial, defense, and maritime applications. This partnership follows Ampera's recent demonstration of a 3D-printed silicon carbide core module, reinforcing the company's focus on factory-built, modular nuclear infrastructure.
