building on more than 70 years of fusion leadership

As Tennessee strengthens its leadership in advanced nuclear energy, the University of Tennessee–Oak Ridge Innovation Institute’s Fusion Technology and Materials for Extreme Environments Convergent Research Initiative is helping advance the future of fusion. Drawing on more than 70 years of fusion research at the University of Tennessee and Oak Ridge National Laboratory, the initiative unites experts across disciplines to solve the scientific and engineering challenges that will move fusion from the laboratory to pilot plants and commercial deployment.

Fusion has the potential to transform the nation’s energy future by providing abundant, reliable, carbon-free electricity using the same process that powers the sun. As public and private investment in fusion energy accelerates worldwide, significant technical challenges remain before commercial fusion power becomes a reality.

The Fusion Technology and Materials for Extreme Environments CRI is focused on overcoming those challenges by developing the technologies, materials and predictive tools needed to move fusion from the laboratory to pilot plants and, ultimately, commercial deployment.

The initiative brings together experts across disciplines to accelerate innovation in three interconnected research areas.

Developing next-generation superconducting magnets for fusion systems.

Creating advanced materials capable of withstanding extreme fusion environments.

Using advanced computing, machine learning and AI to accelerate fusion design and performance.

By integrating expertise across disciplines, the Fusion Technology and Materials for Extreme Environments CRI is accelerating the development of technologies needed for fusion pilot plants and commercial fusion power. The UT-ORNL team is focused on:

  • Advancing technologies critical to future fusion pilot plants
  • Increasing the readiness of fusion materials and systems
  • Accelerating innovation through advanced modeling, artificial intelligence and high-performance computing
  • Training the next generation of scientists and engineers (UT joined with ORNL in 1957 to launch the nation’s first nuclear engineering program. Today, UT’s Nuclear Engineering doctoral program is the largest in the U.S.)
  • Expanding partnerships among academia, national laboratories and industry
  • Attracting investment and strengthening Tennessee’s growing fusion technology ecosystem
