The Fluor [FLR]-led operations contractor at the Department of Energy’s Savannah River Site in South Carolina promoted Dennis Carr to CEO following Stuart MacVean’s retirement on Thursday, a company spokesperson said via email Friday.

Carr becomes president and CEO of Savannah River Nuclear Solutions after serving as an executive vice president and chief operating officer

for the contractor’s increasingly important National Nuclear Security Administration (NNSA) work at the site for the past five years. Carr is a former president of Fluor-BWXT [BWXT] Portsmouth at DoE’s Portsmouth Site in Ohio, according to his company bio and LinkedIn profile.

Carr has been with Fluor as a manager for more than 20 years and altogether has had a 40-year career working on government-owned nuclear and environmental projects, according to his biography.

MacVean told employees earlier this month of his decision to retire as head of the management and operations prime at Savannah River. Huntington Ingalls Industries [HII] is the minority partner in Savannah River Nuclear Solutions. Honeywell [HON] recently announced selling its minority interest in the joint venture to the two remaining partners.

DoE has announced plans to install NNSA as the new landlord for Savannah River effective with the 2025 fiscal year as NNSA starts to spend more at the site, including planned startup of plutonium pit production. DoE’s Office of Environmental Management will continue its cleanup mission at the site as an NNSA tenant.  

In September 2022, DoE reached a long-term extension with Savannah River Nuclear Solutions, potentially keeping the prime in place through September 2027, about two years after NNSA plans to assume responsibility for the site. The prime has been in place since October 2009 and its contract is currently valued at about $24 billion.
