OAK RIDGE NATIONAL LABORATORY TO TURN ON 3D-PRINTED NUCLEAR REACTOR IN 2023
Researchers at the Department of Energy’s Oak Ridge National Laboratory are refining their design of a 3D-printed nuclear reactor core, scaling up the additive manufacturing process necessary to build it, and developing methods to confirm the consistency and reliability of its printed components.
The Transformational Challenge Reactor Demonstration Program’s unprecedented approach to nuclear energy leverages advances from ORNL in manufacturing, materials, nuclear science, nuclear engineering, high-performance computing, data analytics and related fields.
The lab aims to turn on the first-of-its-kind reactor by 2023. The program has maintained its aggressive timeline during the COVID-19 pandemic, using remote work to continue design and analysis efforts.
Reactor development and deployment have traditionally relied on materials, fuels and technology pioneered in the 1950s and ’60s, and high costs and decades-long construction times have limited the United States to building only one new nuclear power plant in the last 20 years.
TCR will introduce new, advanced materials and use integrated sensors and controls, providing a highly optimized, efficient system that reduces cost, relying on scientific advances with potential to shape a new path in reactor design, manufacturing, licensing and operation.
The TCR program has completed several foundational experiments including selection of a core design, and a three-month “sprint” that demonstrated the agility of the additive manufacturing technology to quickly produce a prototype reactor core.
