As global electricity demand accelerates—driven by artificial intelligence, advanced manufacturing, and electrification—nuclear energy is re-emerging as a central pillar of long-term energy security and clean power strategies. The United States, Korea, and Japan each possess complementary strengths in reactor technology, advanced manufacturing, fuel-cycle capabilities, and project delivery, creating a strong foundation for deeper trilateral cooperation. At the same time, intensifying global competition in nuclear exports, supply chains, and advanced reactor development underscores the strategic importance of closer coordination among trusted partners. This session explored how the three countries can expand collaboration across areas such as reactor deployment, next-generation nuclear technologies, fuel supply security, workforce development, and international market engagement. The discussion also examined how strengthened U.S.–Korea–Japan cooperation can help accelerate reliable power deployment to meet rapidly growing electricity demand while reinforcing high standards of safety, nonproliferation, and supply-chain resilience. By bringing together policy, industry, and research perspectives, the session identified practical pathways for translating trilateral alignment into concrete joint initiatives in the coming decade.
