South Korea has reported a U.S. nuclear-investment framework that would allow Korean-designed APR1400 reactors to be built in the United States when financed through South Korean investment funds, easing restrictions imposed under its agreement with Westinghouse. The development is central to a proposed $120 billion, eight-reactor U.S. program that has been discussed as six Westinghouse AP1000 units and up to two APR1400 reactors. The APR1400 would offer U.S. operators an alternative large-reactor design after the supply chain for the ESBWR design collapsed. Both the APR1400 and AP1000 are pressurized water reactors with 60-year design lives, but the Korean design has 1.4 gigawatts of installed capacity, compared with 1 to 1.1 gigawatts for the AP1000. South Korea is promoting its domestic reactor supply chain, construction record in the United Arab Emirates and lower cited costs as advantages in U.S. projects and overseas competitions including Saudi Arabia and Vietnam. The broader U.S. investment framework, including project financing, possible South Korean ownership in Westinghouse, nuclear-liability issues, the Texas Ensenal power project and Alaska LNG, remains under review.
