Thailand and US Partner for Small Modular Nuclear Reactor Feasibility Study
Thailand and the United States have initiated a preliminary feasibility study on small modular nuclear reactors to bolster national energy security.
On September 14, 2026, Thailand and the United States officially entered into an agreement to conduct a preliminary feasibility study regarding the implementation of small modular reactor (SMR) power plants within Thailand. According to Khaosod English, the partnership involves the US Trade and Development Agency (USTDA) and aims to support Thailand’s ongoing transition toward cleaner energy sources while strengthening the nation's overall energy security.
For residents and travelers, this development represents a long-term strategic shift in Thailand’s energy infrastructure. While SMRs are often cited for their potential to provide stable, low-carbon electricity, the project is currently in its earliest investigative phase. There are no immediate changes to the power grid or energy costs, and the study is intended to evaluate the viability of the technology rather than confirm its deployment.
What remains to be confirmed are the specific locations under consideration for potential sites, the projected timeline for any future development, and the final results of the feasibility assessment. As the country explores these advanced nuclear options, stakeholders will be monitoring the study’s findings to determine if SMRs align with Thailand’s environmental and economic goals. For now, the initiative serves as a formal exploration of future energy alternatives.
