US Will Share Tech to Let South Korea Build a Nuclear-Powered Submarine, Trump Says

  • On Oct 29, President Lee Jae Myung asked US President Donald Trump in Gyeongju, South Korea, to allow nuclear fuel supplies for submarines and to revise the decades-old 123 Agreement.
  • Lee said securing approval would allow South Korea to build several conventionally armed submarines using its own technology, replacing diesel-powered submarines that struggle to track North Korean and Chinese ships.
  • Under the 123 Agreement, first signed in the 1970s, Washington must approve South Korean nuclear fuel reprocessing; the pact was updated in 2015 and remains effective until 2035.
  • They could patrol and defend both the East and West Seas of the Korean Peninsula, reducing the operational burden on US forces, while Mr Trump did not directly respond but said he hoped to work with South Korea on shipbuilding and mutual-defence efforts.
  • Reprocessing spent fuel could provide a pathway toward developing weapons, though South Korea cites environmental aims, amid the United States and United Kingdom deal with Australia and China curbing five Hanwha Ocean Co units.
