South Korea Pauses $10 Billion Advance for US Nuclear Project Pending Full Feasibility Review

South Korea has placed a planned $10 billion advance remittance for a United States nuclear power project on hold pending a full review of its business feasibility. Finance Minister Lee Hyoung-il told a parliamentary budget committee on Monday that the transfer remains at a preliminary stage and will be examined carefully before any funds move.⁠Reuters The payment is intended to support Project Power, a Korea-US framework for building up to eight large-scale nuclear reactors in the United States. Industry Vice Minister Park Dong-il separately noted that any potential South Korean investment in the Alaska LNG project is also under close review, with no final decision reached.⁠Reuters Background of the Korea-US Energy Investment Framework The nuclear advance sits inside a larger strategic investment package tied to a bilateral trade and economic agreement. In late September 2026, the two governments jointly announced three energy initiatives under a Korea-US Strategic Investment Memorandum of Understanding: Project Star (a large gas-fired power plant in Texas aimed at AI data centers), Project Power (the nuclear reactor program), and Project North (Alaska LNG).⁠Commerce Project Power outlines a comprehensive cooperation framework to construct eight large reactors—six Westinghouse AP1000 units and two Korean-designed APR1400 units. Total funding allocated to the nuclear effort is up to $120 billion, comprising roughly $100 billion in construction (overnight) costs and $20 billion in contingency reserves. The goal is to contribute to US plans for new large reactors under construction by 2030 while combining American reactor technology with Korean supply-chain and construction capabilities.⁠Commerce Specific sites, individual project structures, construction schedules, and final investment decisions have not been confirmed. Participants are expected to include the two governments, Westinghouse, Korea Electric Power Corporation (KEPCO), and its subsidiary Korea Hydro & Nuclear Power. Korean companies have also been discussed as potential equity investors in Westinghouse, though no terms have been finalized.⁠Mining Why the $10 Billion Advance Exists Nuclear plant construction involves long-lead equipment that can take years to design, manufacture, and deliver. Items such as reactor pressure vessels, steam generators, and reactor coolant pumps often require 50–65 months from order to delivery. Ordering them early is viewed as necessary to keep overall project timelines on track. Cameco, which holds a 49 percent stake in Westinghouse, has indicated that approximately $7.5 billion of any $10 billion advance would be directed toward long-lead AP1000 equipment. South Korean officials have noted that such orders could generate business for Korean manufacturers. Any transfer, however, has always been described as contingent on domestic legal requirements, including a commercial viability review and reporting to the National Assembly.⁠Fnnews Political and Market Context The pause comes against a backdrop of heightened scrutiny. Recent US midterm results that shifted control of Congress have raised questions in Seoul about regulatory and licensing pathways for new nuclear plants, as well as the durability of demand assumptions linked to AI data-center power needs. Opposition lawmakers in South Korea have called for suspending the advance until uncertainties are clearer. Critics argue it is premature to commit large sums when detailed commercial terms remain unsettled and final contracts have not been signed.⁠Biz.heraldcorp South Korean markets have shown sensitivity to the scale of the overall US investment commitments. Officials have previously signaled readiness to act if equity markets overreact relative to fundamentals. The finance minister’s latest comments reinforce that commercial reasonableness and parliamentary procedures must be satisfied before money is sent. Implications for Nuclear Supply Chains and Energy Security If the feasibility review is completed favorably and the advance proceeds, it would support early procurement for a multi-unit program that could add significant baseload capacity in the United States. The inclusion of two APR1400 units would mark the first deployment of the Korean design on American soil, subject to a waiver related to prior intellectual-property arrangements between Westinghouse and Korean entities. For South Korea, the framework offers a path to export construction expertise and equipment while diversifying the country’s overseas nuclear portfolio. For the United States, it aligns with efforts to expand nuclear generation for energy security and large power loads. Both sides have emphasized that individual projects will be announced only as sites, schedules, and commercial terms are finalized. Delays in the advance do not automatically halt longer-term planning. Framework agreements of this type typically allow detailed engineering, site selection, and licensing work to continue while funding and risk-sharing details are resolved. Nuclear projects of this scale routinely face multi-year development periods before concrete is poured. Related Energy Projects Alongside the nuclear review, South Korea continues to examine the Alaska LNG project (Project North). Officials have stressed that no investment decision has been made. Separately, work on the Texas gas plant (Project Star) has moved further along, with some initial capital already transferred under earlier arrangements. The three projects together illustrate the breadth of the bilateral energy agenda, ranging from nuclear baseload to gas capacity for data centers and potential LNG infrastructure. What to Watch Results of the commercial feasibility review and any timeline for a National Assembly report. Whether the $10 billion advance is ultimately approved, reduced, or deferred past year-end. Progress on site selection, licensing, and individual project agreements for the eight reactors. Developments in US nuclear policy and data-center power demand assumptions following the midterms. Any further statements on the Alaska LNG review or equity discussions involving Westinghouse. Market and currency reactions in South Korea as details emerge. South Korea’s decision to require a full feasibility review before releasing the $10 billion advance reflects standard caution on large cross-border infrastructure commitments. The underlying Project Power framework remains in place, and both governments continue to describe nuclear cooperation as a long-term priority. As commercial, regulatory, and political conditions clarify, the pathway for early equipment orders and eventual reactor construction can be assessed with greater precision. The review process itself provides an opportunity to strengthen project structure and risk allocation before significant capital is deployed.
