History

Historical Context

North Korea built the Yongbyon plutonium reactor in the 1980s and, after joining the NPT in 1985, blocked IAEA inspections, sparking a 1993 crisis. The Agreed Framework signed on 12 October 1994 froze Yongbyon’s reactors in exchange for light-water reactors and oil. IAEA chief Rafael Grossi now says expansions at Yongbyon and Kangson annex, operating since January 2026, breach that deal, with 12 centrifuge cascades—about 15 % of pre-freeze capacity.
