What's Happening?
Thailand has approached China for assistance in developing safety regulations for its inaugural small modular reactor (SMR), which is projected to be operational within the next decade. The Office of Atoms for Peace in Thailand intends to leverage China's
extensive experience, particularly its supply chain control systems, before deploying its first SMR. Rungruang Kittiphati, the agency's secretary-general, highlighted China's fully integrated nuclear sector, which encompasses all stages from reactor design and uranium production to waste management and plant decommissioning. The Electricity Generating Authority of Thailand (Egat) plans to construct a 300 MW SMR, with commercial operation anticipated by 2037 as part of Thailand's 2026 Power Development Plan. Thailand is also engaging with international partners, including the United States, to assess the project's technical feasibility and best practices. The inclusion of SMRs in the energy plan aims to bolster energy security, support net-zero emissions targets, and meet the increasing electricity demands from advanced industries and data centers. Thai regulators are currently formulating a detailed licensing framework that will incorporate new cooling technologies and floating nuclear installations, utilizing the International Atomic Energy Agency's Generic Reactor Safety Review as a primary safety assessment standard. As of August, China operated 64 nuclear reactors, with an additional 56 under construction or approved, and its nuclear generation in 2025 reached 468 billion kilowatt-hours, accounting for 4.82% of its national electricity production. China's developments include the ACP100 on Hainan Island, the world's first land-based commercial SMR, expected to commence operations in early 2027.
Why It's Important?
This collaboration between Thailand and China on nuclear safety for SMRs holds significant implications for the global energy landscape and U.S. interests. For Thailand, adopting SMR technology and seeking Chinese expertise underscores a strategic move towards enhancing energy security and achieving climate goals, potentially reducing reliance on fossil fuels. The U.S. has also been involved in discussions with Thailand regarding SMR projects, indicating a competitive yet cooperative environment in nuclear energy development. China's role as a key partner in developing nuclear safety frameworks could solidify its influence in the international nuclear energy sector, particularly in Southeast Asia. This could impact the market for U.S. nuclear technology and services, as countries might increasingly look to China for comprehensive nuclear solutions. The development of SMRs, particularly the ACP100 in China, demonstrates a growing global trend towards smaller, more flexible nuclear power solutions, which could reshape future energy infrastructure. For U.S. industries, this highlights the need to remain competitive in SMR technology and regulatory frameworks to maintain its position as a leader in nuclear innovation. The broader adoption of SMRs, facilitated by international cooperation on safety standards, could accelerate the global transition to cleaner energy sources, but also raises questions about the standardization and interoperability of different national nuclear technologies and regulatory approaches.
What's Next?
Thailand's Office of Atoms for Peace will continue to develop its detailed licensing framework for SMRs, incorporating insights from China's experience and adhering to the International Atomic Energy Agency's Generic Reactor Safety Review. The Electricity Generating Authority of Thailand (Egat) will proceed with its plans to construct the 300 MW SMR, aiming for commercial operation by 2037. Further agreements and collaborations with international partners, including the United States, are expected as Thailand studies the technical feasibility and best practices for its SMR project. China's ACP100 SMR on Hainan Island is anticipated to begin operating in early 2027, providing a real-world case study for other nations considering similar technologies. The ongoing development and deployment of SMRs globally will likely lead to increased international dialogue on regulatory harmonization, safety standards, and supply chain management in the nuclear energy sector. This could also spur further competition and collaboration among major nuclear technology providers, including the U.S. and China, as they vie for market share and influence in the burgeoning SMR market. The success of Thailand's SMR project, supported by Chinese expertise, could serve as a model for other developing nations looking to adopt advanced nuclear technologies for energy security and decarbonization.
