A close-up of a laboratory experimental setup showing a cylindrical metal vacuum chamber with a circular optical viewport emitting bright blue light. A FLIR camera and optical sensors are mounted on an aluminum rail aimed at the glowing chamber interior. The viewport is surrounded by bolts and insulation straps, and a hinged metal mesh cover is open to the right, revealing the illuminated interior used for diagnostics or plasma experiments.

Researchers at ORNL are helping to enable the next generation of abundant, affordable nuclear energy by combining 80 years of know-how with the latest scientific techniques, facilities and equipment. The lab’s longstanding expertise in degradation of materials in the harsh environments of nuclear reactors make it the go-to place for a resurgence of interest in liquid metals and molten salts for both advanced fission and fusion reactors. 

Kyoto Fusioneering’s UNITY-1 blanket and thermal cycle test facility will complement the new breeding blanket testing infrastructure being developed with ORNL.

ORNL is partnering with Kyoto Fusioneering on a new public-private partnership that leverages each institution’s expertise in fusion technology to develop world-leading fusion test facilities and technology and accelerate the deployment of commercial fusion power. 

An illustrative rendering of Type One Energy’s high-heat flux facility depicts the high-temperature helium loop (left) and the vacuum vessel (center).

ORNL, Type One Energy and the University of Tennessee, Knoxville, are partnering to establish a world-class facility that will drive American innovation and move fusion energy closer to reality. This high-heat flux facility, located in TVA’s Bull Run site in East Tennessee, will evaluate how materials react under extreme conditions in a fusion device.

MPEX is a new ORNL facility designed to recreate the extreme conditions at the edge of fusion reactors so researchers can test how plasma-facing materials survive. Its capabilities will speed the development of durable components needed for future fusion power plants.

Three men sit around a table in an office, discussing documents and taking notes. Open reference books lie on the table, and shelves filled with books and files are visible in the background.

Decades of nuclear fission research are providing critical insights to help scientists design the next generation of fusion systems, and few understand that connection better than ORNL’s Michael Loughlin.
