① US Nuclear Investment Boom — Why Now?
The United States is in the midst of its most significant nuclear energy renaissance since the 1970s. The confluence of three irresistible forces — surging AI data center power demand, climate decarbonization mandates, and a bipartisan political consensus on energy security — has ignited a nuclear investment wave that is now measured in the hundreds of billions of dollars.
The numbers are staggering. Global nuclear power generation is expected to grow by nearly 3% annually through 2026, reaching a new all-time high, with an additional 29 GW of nuclear capacity anticipated to come online worldwide. In the US specifically, every major technology company — Microsoft, Amazon, Google, Meta — has signed nuclear power purchase agreements or invested directly in reactor developers, creating an unprecedented demand signal that is reshaping the entire nuclear supply chain.
Here is the critical investment insight: American domestic nuclear manufacturing capacity has been hollowed out over 40 years of dormancy. The US has the regulatory framework, the capital, and the demand — but it lacks the manufacturing execution. That gap is now being filled by South Korean industrial giants who have built nuclear infrastructure on time and on budget, most famously at the UAE’s Barakah plant. Korea’s entry into the US nuclear supply chain is not optional for America’s nuclear future — it is essential.

② SMR Revolution — Technology Overview
The nuclear investment wave is being led by Small Modular Reactors (SMRs) — factory-built, standardized reactors with output of 50–300 MW each (vs. 1,000+ MW for conventional large reactors). The SMR landscape in 2025 showcases over 80 diverse designs, with the most promising now moving from design into commercial deployment. SMRs are ideal for AI data centers because they can be deployed close to demand centers, their modular nature allows incremental capacity additions, and their small footprint enables siting where large nuclear plants cannot go.
⚛️ X-energy Xe-100
High-temperature gas-cooled reactor using TRISO-X pebble fuel. X-energy, Amazon, KHNP, and Doosan Enerbility announced a strategic partnership in August 2025 to accelerate deployment of Xe-100 SMRs to meet growing power demands from data centers and AI. Fourth-generation design with inherent safety — cannot melt down by physics.
Korean role: KHNP (engineering) + Doosan (reactor components)
🔋 KHNP i-SMR
Korea’s own domestically designed SMR — the i-SMR (innovative SMR) — with 170 MW output per unit. Already in feasibility study for deployment in Norway (Aure and Heim municipalities). Designed for industrial applications, district heating, and electricity generation. Targets NRC pre-licensing in the US.
Norway feasibility study ongoing with Korea Eximbank support
🏭 TerraPower (KHNP Stake)
In January 2026, KHNP invested $40 million to acquire a stake in US-based TerraPower from SK Innovation — the first direct investment by a Korean public energy enterprise in an SMR developer. TerraPower’s Natrium reactor uses liquid sodium cooling and a molten salt thermal storage system for dispatchable clean power.
