📄 Abstract（原文）
Nuclear energy is increasingly emerging as a central component of clean and sustainable power systems, supporting both decarbonization objectives and energy security in the context of the global net-zero transition. As electrification accelerates across sectors—including transport, industry, and digital infrastructure—the need for reliable, low-carbon baseload generation is becoming more acute. At the same time, the rapid expansion of energy-intensive applications such as artificial intelligence, data centers, and advanced manufacturing is placing unprecedented stress on electricity systems, reinforcing the strategic importance of dispatchable, high-density energy sources. Within this evolving landscape, nuclear power is regaining prominence. Policy shifts across major economies, from the United States to the European Union and Asia, reflect a renewed recognition of nuclear energy as a necessary complement to variable renewable sources. Ambitions to triple global nuclear capacity by 2050 further underscore the scale of the challenge ahead. However, this renewed momentum also exposes structural vulnerabilities embedded within the current nuclear fuel cycle. Uranium, which underpins the existing fleet of nuclear reactors, occupies a dual position: it is essential for expanding nuclear generation while remaining a strategically sensitive resource affected by geopolitical volatility. The uranium market has experienced significant turbulence in recent years, with rising prices, supply disruptions, and growing fragmentation between Western and Eastern supply chains. Constraints in conversion and enrichment capacity have further amplified these pressures, highlighting the fragility of a system that must now scale rapidly1.
