Amentum opens Global Nuclear hub in Tennessee.

Amentum opens Global Nuclear hub in Tennessee. Amentum has opened its Global Nuclear headquarters in Oak Ridge, Tennessee, housing its Nuclear Center of Excellence and serving as a hub for the company's international nuclear operations. "The opening of our Global Nuclear Headquarters represents a monumental step forward for our business and our industry," said Mark Whitney, president of Amentum's Energy & Environment division. "By centralizing our global nuclear operations in Oak Ridge, we are leveraging strong local partnerships to deliver increased energy capacity to meet the electricity demand of the people and businesses across the U.S. This facility empowers our team of experts to deliver next-generation nuclear innovation, and it builds directly upon the strong operational foundation we've established in the region through our Amentum-led UCOR partnership while contributing directly to regional economic growth." The hub employs over 150 subject matter experts working on innovative engineering, technology solutions and advanced energy capabilities. The facility strengthens Amentum's footprint in east Tennessee, where it already serves as the lead partner in Energy Department's United Cleanup Oak Ridge. The company also launched the Amentum Nuclear Scholars Program, which establishes a synchronized scholarship pipeline between Roane State Community College and the University of Tennessee, Knoxville. The partnership is headlined by a 5-year investment from Amentum totaling $500,000 to develop curriculum and scholarships for a talent pipeline for nuclear energy demands. Combined with other Amentum-led STEM sponsorships and donations in the Oak Ridge community, total student support for these two academic institutions exceeds $1 million, the company said. "By launching the Amentum Nuclear Scholars Program alongside our new headquarters, we are directly investing in the local student talent who will pioneer the future of advanced energy and infrastructure solutions," Whitney said. The educational pipeline will launch its first student cohort stateside in late 2026. "This partnership paves the way for students to gain the educational foundation necessary to excel as future leaders in the nuclear industry," said UTK Tickle College of Engineering Dean Matthew Mench, the Wayne T. Davis dean's chair of the college. "Through the financial support from Amentum and practical internship experiences, TCE students will be prepared to step directly into high-demand roles that will positively impact our community, state and country." Amentum hosted a ribbon-cutting ceremony to celebrate the opening with its CEO John Heller, U.S. Rep. Chuck Fleischmann (R-TN-03) and local elected leaders and school officials. "By partnering with Amentum, we are opening doors for students to start right here in their community and graduate onto a global stage," said Dr. Chris Whaley, Roane State Community College president. "The Amentum Nuclear Scholars Program removes the financial hurdles that often halt a student's momentum, providing a direct, supported pathway from our classrooms straight into high-wage, high-impact careers."
