Can advanced nuclear partnerships between X-energy, Amazon, KHNP, and Doosan transform AI power infrastructure in the U.S.?

X-energy Reactor Company, Amazon, Korea Hydro & Nuclear Power Corporation (KHNP), and Doosan Enerbility have signed a landmark agreement to deploy advanced nuclear energy across the United States, targeting over five gigawatts of new capacity by 2039. The partnership, announced in Washington, underscores how nuclear technology is being repositioned to meet the surging energy demands of artificial intelligence infrastructure, data centers, and industrial electrification.

The agreement commits the parties to mobilize up to USD 50 billion in combined public and private investment, while also expanding the nuclear supply chain to support Xe-100 small modular reactor (SMR) deployment. The initiative is closely aligned with the recent USD 350 billion U.S.–South Korea trade deal, reinforcing energy and technology collaboration between the two nations.

Why are Amazon and X-energy turning to advanced nuclear reactors to power AI data centers and digital infrastructure?

The announcement reflects one of the clearest examples of how hyperscale cloud operators like Amazon Web Services are now seeking carbon-free baseload power at scale. AWS executives noted that data centers have become the backbone of AI leadership, and meeting rising demand requires reliable clean energy sources.

Unlike intermittent renewables, X-energy’s Xe-100 SMR design offers continuous power output, with TRISO-X fuel technology considered among the safest and most proliferation-resistant in the nuclear industry. By partnering with KHNP and Doosan Enerbility, Amazon gains access to proven South Korean nuclear manufacturing capacity, while X-energy secures a global-scale partner for accelerating deployment.

What role will Korean partners KHNP and Doosan play in enabling U.S. advanced nuclear growth?

KHNP, South Korea’s leading nuclear operator, brings decades of experience in operating large-scale reactors, while Doosan Enerbility is one of the world’s most established nuclear equipment manufacturers. Executives from both firms emphasized that global competition in small modular reactor deployment is intensifying, making U.S.–Korea cooperation strategically significant.

Doosan’s Chairman Park Ji-won stated that the group would leverage its advanced manufacturing capabilities to scale Xe-100 reactor components. KHNP’s leadership stressed that strengthening U.S.–Korea nuclear ties would generate strong synergies in the global SMR market, allowing both countries to advance climate goals while bolstering energy security.

How does this partnership align with U.S. energy policy and institutional investor sentiment?

The deal directly ties into the Trump administration’s ongoing push to commercialize advanced nuclear technologies. X-energy already secured a critical step in May 2025 when its four-reactor project with Dow Inc. in Texas entered the U.S. Nuclear Regulatory Commission’s 18-month construction permit review.

Institutional investors have increasingly flagged nuclear as a viable long-term asset class, with analysts pointing to its role in stabilizing grids as renewables expand. The commitment of USD 50 billion in investment opportunities suggests that financiers see nuclear not only as an energy play but as an infrastructure backbone for the AI economy.

From a market sentiment perspective, investors in both U.S. utilities and Korean industrial majors may view this partnership as a hedge against rising natural gas volatility and renewables intermittency. Analysts suggest nuclear-linked equities, particularly in firms like Doosan Enerbility, could benefit from heightened visibility in U.S. infrastructure markets.

What progress has X-energy already made toward Xe-100 commercialization and what are the next milestones?

X-energy’s flagship project with Dow Inc. at the UCC Seadrift Operations site remains one of the most closely watched demonstration projects in the SMR space. The U.S. Department of Energy has already backed it under the Advanced Reactor Demonstration Program.

Beyond Texas, X-energy is preparing its second deployment at Energy Northwest in Washington state, where an initial four reactors are expected to expand to 12 units. Amazon is a direct stakeholder in that project, positioning it as the first hyperscale operator to integrate nuclear power into its AI data center energy mix.

Industry observers believe the involvement of KHNP and Doosan will help address key bottlenecks around supply chain scaling, manufacturing capacity, and reactor cost efficiency, issues that have historically slowed U.S. nuclear expansion.

Could this U.S.–Korea partnership shift the global balance of nuclear innovation and AI energy leadership?

Analysts note that China and Russia have sought to dominate the SMR export market, with several reactor models already in demonstration. By linking AI infrastructure needs to advanced nuclear deployment, the United States and South Korea aim to leapfrog rivals by aligning two fast-growing industries.

If successful, the collaboration could mark the beginning of nuclear–AI co-development as a global industrial strategy. That framing positions the U.S. and South Korea not only as energy partners but as strategic players in the competition for AI leadership, where electricity availability is becoming as important as algorithmic capability.

How are investors and institutional analysts viewing the market outlook for nuclear energy partnerships powering AI and data center infrastructure?

Publicly traded players involved in the collaboration provide early signals of investor sentiment. Doosan Enerbility has historically seen strong domestic support from South Korean investors, while X-energy remains privately held. For Amazon (NASDAQ: AMZN), the move reinforces its climate-neutral pledge while also addressing shareholder concerns about rising energy costs for AWS.

Analysts caution that deployment risks remain high, including regulatory hurdles, construction timelines, and capital intensity. However, the upside case positions nuclear as a necessary enabler of AI-driven growth, with long-term institutional flows likely to back projects that achieve critical regulatory approvals.

Looking forward, investors will be closely tracking upcoming project milestones at Dow’s UCC Seadrift site in Texas, which has already advanced into the U.S. Nuclear Regulatory Commission’s 18-month review, and at Energy Northwest in Washington state, where Amazon is directly tied to the development of up to a dozen Xe-100 reactors. These sites are viewed as bellwethers for whether advanced nuclear can move from pilot stage into reliable commercial deployment.

Market observers suggest that each regulatory clearance, construction permit, and initial reactor build-out will serve as a credibility marker for the broader small modular reactor sector. For Amazon in particular, additional announcements regarding nuclear integration into its global data center footprint could redefine how hyperscalers manage energy security. Analysts emphasize that such disclosures would not only validate nuclear as a scalable option for cloud operators but could also reshape long-term power purchase agreement structures in the digital economy.

If the initiative achieves its stated goal of delivering more than five gigawatts of carbon-free baseload energy by 2039, nuclear-backed AI infrastructure could become one of the defining industrial shifts of the late 2020s and 2030s. The ability to pair AI-driven growth with nuclear resilience positions this partnership at the intersection of two megatrends: the rapid expansion of artificial intelligence workloads and the urgent demand for reliable, clean, and geopolitically secure power. For investors, that convergence is increasingly seen as a rare thematic play that bridges both the energy transition and the digital transformation storylines.
