Solstice Advanced Materials Expands Uranium Conversion Capacity to Meet Nuclear Renaissance Demand
Illinois facility increases uranium hexafluoride production by 20% amid surging nuclear energy growth and $2 billion order backlog.
Illinois,
United States: Solstice Advanced Materials announced in
February 2026, a significant capacity expansion at its Metropolis Works uranium
conversion facility in Illinois, targeting production exceeding 10 kilotonnes
of uranium hexafluoride (UF6) annually, representing approximately a 20%
increase from current output levels. The Metropolis plant, operating under the
ConverDyn joint venture with General Atomics and Honeywell, is the sole
commercial uranium conversion facility in the United States and has been
operational since 1958. The expansion addresses a substantial order backlog
exceeding $2 billion through 2030 from long-term customers, predominantly
domestic utility companies. Investment has focused on debottlenecking projects
at the facility, which successfully restarted operations in 2023 following
idling between 2017 and 2023 due to adverse market conditions. The capacity
increase aligns with the U.S. government's objective to quadruple the nation's
nuclear energy capacity by 2050 as part of a nuclear renaissance driven by
artificial intelligence, data center proliferation, and industrial
electrification.
According
to David Sewell, Solstice President and CEO, “Solstice
has stepped up production of UF6, a critical component in the
nuclear fuel supply chain, with the support of disciplined capital investments
and improved operational excellence at our Metropolis Works facility.
Leveraging our 60-plus years of operational excellence, industry leadership and
proprietary expertise, we are exceedingly well-positioned to ensure our
capacity to produce converted uranium is aligned with the industry and its
rapid expansion.”
According to TechSci
Research, Solstice's capacity expansion at Metropolis Works capitalizes on a
transformational shift in global energy infrastructure, with nuclear power
experiencing unprecedented demand growth driven by AI computational
requirements and decarbonization imperatives. As the only commercial uranium
conversion facility in the United States, Solstice holds a strategically
advantageous monopolistic position within domestic supply chains, particularly
given geopolitical tensions that increasingly favor localized nuclear fuel
production capabilities. The company's $2 billion order backlog provides
exceptional revenue visibility through 2030, while ongoing engineering analysis
for additional capacity expansion suggests sustained long-term growth
prospects. However, the facility's environmental litigation history and pending
legal settlements present ongoing operational and reputational risks that
warrant monitoring. The nuclear fuel cycle's renaissance positions Solstice as
a critical enabler of America's energy transition, with potential for
substantial margin expansion as capacity constraints ease and operational
efficiency improves.
