South Korea is rapidly positioning itself at the forefront of the global nuclear energy renaissance, propelled by a sweeping new government strategy and a surge of private sector innovation. On May 19, 2026, the Ministry of Science and ICT convened an inaugural meeting at the H Hotel in Osong, Sejong City, to kick off the formulation of the 7th Comprehensive Nuclear Promotion Plan, a legally mandated five-year roadmap that will set the tone for the nation's nuclear ambitions from 2027 to 2031. The plan’s core aim is bold: to establish South Korea as the world’s preeminent nuclear powerhouse, leveraging next-generation Small Modular Reactors (SMRs) and artificial intelligence (AI) to outpace global competitors.
The significance of this move is hard to overstate. According to Insight Energy News, the Nuclear Promotion Plan, first established in 1997 under Article 9 of the Nuclear Promotion Act, has already delivered six successful iterations, each reinforcing the country’s energy security, export capacity, and technological self-reliance. But this seventh plan is different. It arrives at a time when climate change, AI-driven power demand, and energy security concerns are converging, making nuclear energy—especially SMRs—a linchpin of both national policy and international competition.
The government’s strategy is comprehensive. As reported by DongA Science and Today Busan, a committee of roughly 90 experts from government, academia, and industry has been assembled to craft execution strategies across four pillars: ultra-innovative growth, public safety assurance, convergence expansion, and foundation strengthening. The ultra-innovative growth track, perhaps the most ambitious, targets rapid acquisition of SMR technology and private sector-led commercialization by 2030. This includes launching mega-projects that unite public and private interests, integrating AI with SMR operations for a global edge, and building the policy and industrial infrastructure needed for export success.
Public safety is another cornerstone. The plan calls for advanced safety technologies for operating reactors, expanded applications such as flexible operation and clean hydrogen production, and the optimization of radioactive waste management. By developing an integrated data management platform for the nuclear lifecycle, the government hopes to reassure citizens and future generations that nuclear energy can be both safe and sustainable.
Convergence expansion, meanwhile, focuses on leveraging radiation technologies to tackle carbon neutrality, environmental pollution, aging populations, and food security. The foundation strengthening agenda seeks to expand fundamental research, nurture a skilled workforce, and deepen international cooperation—key ingredients for sustaining global leadership.
“The establishment of the 7th Comprehensive Nuclear Promotion Plan will be a turning point for our nuclear industry, moving from technological independence to global market leadership,” said Oh Dae-hyun, Director of Future Strategic Technology Policy at the Ministry of Science and ICT, as quoted by DongA Science. “We will develop a systematic strategy so that nuclear energy can robustly support both our economy and the lives of our people.”
The private sector is already responding. On May 20, 2026, X-energy, a prominent player in the next-generation SMR field, announced a suite of milestones: securing a U.S. Nuclear Regulatory Commission (NRC) license for advanced nuclear fuel, completing a Nasdaq IPO, and raising $1.1 billion in new capital. According to Choice Stock AI, X-energy boasts a project pipeline of 144 reactors—totaling approximately 11,500 MW—across the U.S., Canada, and the UK, with first commercial supply targeted for the early 2030s. The company’s revenue model is built on technology license fees and long-term nuclear fuel sales, with a single four-reactor Xe-100 plant projected to generate up to $4.7 billion in lifetime revenue.
X-energy’s progress is emblematic of the sector’s momentum. From January to April 2026, the company inked a 10-year graphite supply deal with SGL Carbon, secured the first Category II NRC license for advanced fuel via its subsidiary TRISO-X, and formed key partnerships with Japan’s IHI and Tailen for supply chain expansion and market entry. Its Oak Ridge-based TX-1 fuel plant is slated for a late 2028 launch, capable of fueling up to 11 Xe-100 reactors per year. Regulatory approval is moving apace, with construction permits for the DOE project expected by early 2027.
South Korea’s construction industry is also stepping into the global spotlight. As reported by Chosun, Holtec International’s first commercial SMRs—Pioneer Units 1 and 2—are nearing construction at the Palisades site in Michigan, with Hyundai Engineering & Construction as the main contractor. The U.S. Department of Energy has awarded $400 million in subsidies to the project, underscoring its strategic importance. Holtec recently convened a technical advisory committee with experts from 22 countries, including Korea, to validate design and construction prowess. Korean firms have proven themselves irreplaceable in the global nuclear supply chain, thanks to their track record of delivering projects on time and within budget, such as the Barakah nuclear plant in the UAE.
The SMR market is heating up worldwide, fueled in part by surging AI data center energy needs. Tech giants like Microsoft, Google, and Amazon are reportedly inking power purchase agreements for SMR-generated electricity, while countries from Canada to Armenia are rolling out or expanding national SMR adoption plans. Other major players include NuScale Power, GE Hitachi, Westinghouse, and, of course, X-energy.
On the local front, South Korean communities are racing to host the next wave of nuclear innovation. In Busan’s Gijang County, a civilian-led committee was launched on May 19 to campaign for the siting of an innovative i-SMR plant. Around 200 local residents and leaders gathered at the Gori Nuclear Sports Culture Center, unified by the belief that i-SMR technology represents not just a safer, more efficient energy solution, but also a lifeline for regional economic revitalization. The committee’s efforts are especially urgent, as the final site decision will follow the June 3 local elections, with Gijang facing stiff competition from Gyeongju.
Meanwhile, Ulsan City announced plans to review and promote SMR development projects from the second half of 2026, working closely with local companies like HD Hyundai Heavy Industries. While the specifics are still being hammered out, Ulsan’s previous investments in SMR research and the newly enacted SMR Special Act—which supports SMR development and is set to be fleshed out by September—signal a growing regional commitment to nuclear innovation.
Crucially, South Korea’s regulatory environment is evolving to keep pace. The SMR Special Act, passed in March 2026, enables the creation of an SMR Development Promotion Committee to streamline research, development, and policy oversight. The Nuclear Safety Act has also been amended to allow for faster, more tailored safety reviews for new reactor designs—a move welcomed by industry and experts alike, who had long argued that legacy regulations disadvantaged SMRs compared to traditional large reactors.
As the 7th Comprehensive Nuclear Promotion Plan moves toward finalization—expected within 2026 after public consultations—South Korea seems poised for a new era. With government, industry, and local communities aligned, the country is betting big that nuclear energy, and SMRs in particular, will not only secure its own energy future but also help define the global standard for clean, reliable power in the decades to come.
