East Tennessee: Where the Future of Nuclear Energy Is Being Built

Why It Matters

East Tennessee’s nuclear ecosystem accelerates U.S. clean‑energy goals and strengthens national security by delivering cheaper, advanced reactors at scale.

Key Takeaways

• East Tennessee hosts over 150 nuclear companies in a collaborative ecosystem
• Oak Ridge Lab partners with TVA, federal agencies on reactor tech
• 3D‑printed components installed in reactors showcase advanced manufacturing breakthroughs
• BWXT 300 design permit filed for smaller, next‑gen boiling water reactor
• Kairos leverages Oak Ridge expertise to cut civil‑structure costs for Hermes 1

Summary

The video spotlights East Tennessee as the nation’s premier nuclear innovation hub, anchored by Oak Ridge National Laboratory’s historic legacy and a dense cluster of more than 150 nuclear firms. It underscores how the region’s unique blend of scientific expertise, advanced facilities, and a collaborative culture is attracting both established players and emerging startups. Key data points include the partnership network linking ORNL, the Tennessee Valley Authority, and federal agencies to accelerate reactor design, exemplified by a 3D‑printed component now operating in a test reactor. The BWXT 300 design—a smaller, technologically advanced boiling‑water reactor—has secured a construction permit, while Kairos Energy is building the Hermes 1 reactor building, leveraging Oak Ridge’s cost‑saving civil‑structure innovations. Speakers emphasize the symbolic rebirth of nuclear energy in the area, noting, “This is where nuclear energy was born… and will be reborn.” They cite concrete examples of joint research, advanced manufacturing, and workforce development that only a federal‑backed lab can provide. The ecosystem positions the United States to enhance national security, reduce carbon emissions, and regain global competitiveness in nuclear power, while driving down capital costs for next‑generation reactors nationwide.

Original Description

Nuclear science didn't just start at Oak Ridge National Laboratory — it was born here. Founded as part of the Manhattan Project, ORNL has spent decades forging the path of nuclear innovation, and that mission is accelerating.

East Tennessee is now home to more than 150 nuclear companies, forming one of the most powerful energy ecosystems in the world. Through groundbreaking partnerships with Tennessee Valley Authority, Kairos Power, and the Department of Energy, the region is pioneering everything from 3D-printed reactor components and advanced fuel types to next-generation reactor designs like the Hermes prototype currently under construction.

From the fuel cycle to workforce development, ORNL and its partners are proving that East Tennessee isn't just where nuclear energy began — it's where nuclear energy will be reborn.
