US and South Korea announce $120 billion framework to build up to eight nuclear reactors on American federal sites
The United States and South Korea announced a non-binding framework on September 30, 2026, under which Korea would invest $120 billion to help finance the construction of up to eight nuclear reactors on federally designated sites across the country. The planned fleet includes six Westinghouse AP1000 units and up to two Korean APR1400 reactors — a combination that would make the deal one of the largest nuclear energy commitments in American history.
Framework calls for up to eight reactors on US federal land
The announcement came under an existing Memorandum of Understanding between the two governments. Korea would finance up to six Westinghouse AP1000 reactors and up to two Korean APR1400 reactors, all on federal sites designated by the US. The plan starts with two AP1000 units and scales up from there.
Nothing’s locked in yet. The framework is explicitly non-binding and still has to clear a significant number of hurdles before any real work begins — definitive agreements, site identification, regulatory approvals, finalized financing arrangements. The $120 billion figure is an intention, not a signed check.
Regulatory approvals alone can take years in the US nuclear sector, and site selection, environmental reviews, and construction logistics all add further complexity.
Framework builds on existing US–Korea nuclear partnership and IP settlement
This deal didn’t come out of nowhere. It extends a strategic partnership announced in October 2025 between Cameco, Brookfield Asset Management, and the US Department of Commerce — a relationship that had already laid the groundwork for deeper nuclear cooperation between the two countries.
One of the more technically significant pieces involves intellectual property. Westinghouse reached a settlement in 2025 with Korea Electric Power Corporation (KEPCO) and Korea Hydro & Nuclear Power Co. (KHNP) over an IP dispute, and the new framework contemplates a one-time waiver under that settlement. That waiver would allow up to two APR1400 reactors to be built on American soil for the first time.
The financial stakes are real. Each APR1400 unit is expected to generate approximately $2 billion in value for Westinghouse — through IP licensing fees, engineering and procurement services, subcontracting opportunities, and long-term fuel fabrication contracts. Westinghouse’s role across both reactor types would be substantial.
Worth clarifying: this framework is separate from the US Department of Energy’s American Nuclear Supply Chain Loans conditional commitment. Cameco made that explicit. It’s a distinct program with its own timeline and conditions.
Korea may take an equity stake in Westinghouse under the deal
Beyond financing reactor construction, the framework opens the door to something more structural — a potential equity investment by South Korea in Westinghouse itself. That would give Korea a direct financial stake in one of the world’s leading nuclear technology companies, tying it more closely to Westinghouse’s global reactor deployment program.
Any such investment remains conditional. It would require definitive agreements, due diligence, corporate approvals, and regulatory sign-off before moving forward. For Cameco, which co-owns Westinghouse alongside Brookfield Asset Management, a Korean equity stake raised an obvious question about dilution. The company addressed it directly: Cameco doesn’t expect any potential Korean equity participation to affect its own ownership interest in Westinghouse, though how exactly that gets structured hasn’t been worked out yet.
Deal aims to advance US goal of quadrupling nuclear capacity by 2050
The US government has set an ambitious target of quadrupling its civil nuclear capacity by 2050. Cameco CEO Tim Gitzel framed the framework squarely within that goal.
“We are pleased to see the US government continuing on a path to expanding nuclear power capacity in the US,” Gitzel said in a statement. He added that Cameco’s priority remains the Department of Energy’s American Nuclear Supply Chain Loans conditional commitment, under which AP1000 construction timelines could accelerate by as much as three years.
New AP1000 orders — like those envisioned by this framework — are seen as a way to reduce risk and speed up the global rollout of the AP1000 fleet. More orders generally mean more supply chain development, more manufacturing experience, and better cost predictability across future projects. Even so, the road from framework to operating reactor is long. Regulatory approvals alone can take years in the US nuclear sector, and site selection, environmental reviews, and construction logistics all add further complexity.
What the framework means — and what still needs to happen
Here’s where things stand: the US and South Korea have announced a non-binding framework under which Korea would invest $120 billion to finance construction of up to eight nuclear reactors — six AP1000s and up to two APR1400s — on federally designated land. The deal builds on a 2025 strategic partnership involving Cameco and Brookfield Asset Management, and it contemplates a one-time IP waiver that would allow Korean reactor technology to be built in the US for the first time.
South Korea could also take an equity stake in Westinghouse Nuclear, subject to its own set of conditions. Cameco says its ownership interest wouldn’t be affected.
The framework is designed to support the US goal of quadrupling nuclear capacity by 2050, with AP1000 construction timelines potentially accelerating by up to three years under a parallel DOE loan program. Before any of this becomes reality, both governments and their partners need to finalize agreements, identify sites, and lock down financing. The framework sets a direction — the details will determine whether it gets there.
