South Korea and the United States have agreed in principle to execute about $10 billion of Korean investment this year through advance orders for long-lead equipment for future U.S. nuclear plants, rather than an upfront cash transfer before projects are finalized. The broader nuclear framework covers an estimated $120 billion project to build eight reactors—six Westinghouse AP1000 units and two Korean-designed APR1400 units—and includes a reserve of up to $20 billion, or about 27 trillion won, for cost overruns. Unused reserve funds would still count toward Seoul’s investment commitment, while additional Korean funding would not be automatic if overruns exceed the reserve. The equipment orders, whose components can take four to five years to deliver, are intended to accelerate construction and could generate contracts and revenue for Korean nuclear companies. Separately, a combined-cycle gas plant in Encinal, Texas, is the first selected project under South Korea’s wider $350 billion U.S. commitment, while Alaska LNG remains at an earlier stage.
