South Korea is pressing to secure enriched uranium from the United States to fuel a nuclear-powered submarine it plans to construct domestically, as revealed by a South Korean official. During recent summit discussions, President Lee Jae Myung requested U.S. President Donald Trump’s assistance in obtaining the fuel to realize this initiative at home.

According to the official, Washington has sanctioned Seoul's use of nuclear fuel for the submarine, albeit under an agreement that prohibits reprocessing spent fuel or enriching uranium for military use. Despite possessing nuclear reactors for energy, South Korea's aspirations to build a nuclear-powered submarine are clashing with Trump's statements suggesting construction will occur at the Hanwha Philly Shipyard.

The situation has spurred debates in South Korea over the construction logistics and has led to political calls for the submarine to be built domestically. Concurrently, the U.S. and South Korea are drafting a comprehensive fact sheet detailing their new $350 billion investment agreement. This document is being refined, although both parties affirm there is no disagreement on tariff matters.
