Programme under the US–South Korea nuclear framework announced on September 30, 2026: eight large reactors on US sites, six Westinghouse AP1000s (three two-unit plants on federal sites) and two Korean APR1400s. South Korea would provide up to USD 120 billion (about USD 100 billion for construction and a USD 20 billion contingency), and Korean companies may take a 5 to 10 percent stake in Westinghouse. Korea could advance up to USD 10 billion by year-end for long-lead items, pending legal approvals. The two governments, Westinghouse, KEPCO and KHNP are signatories. It is a non-binding framework: sites, structures, schedules, a commercial reasonableness review and Korean parliamentary approval are still needed, and no dates were given. Commerce Secretary Lutnick named Ohio, Tennessee, South Carolina and Kentucky, but sites are not confirmed. Capacity is the sum of ANS-quoted unit ratings (1,110 MWe per AP1000, 1,400 MWe per APR1400).
