North Korea boosting ability to manufacture nuclear arms, IAEA chief warns

Key Points

• The IAEA chief confirms North Korea is making 'very serious' progress in nuclear weapons production, with satellite imagery showing a new uranium enrichment facility at Yongbyon.
• Activity has surged at Yongbyon's five-megawatt reactor, reprocessing unit, and light-water reactor, indicating a marked increase in weapons-grade material generation.
• North Korea's current nuclear stockpile is estimated at several dozen warheads, but the new enrichment capacity could push this to 50-70 in the near term.
• Uranium enrichment provides a faster, more effective path to weapons-grade material, complementing plutonium reprocessing and making the program more resilient.

IAEA Director-General Rafael Grossi warned that North Korea is making 'very serious' advances in its nuclear weapons production capacity. Satellite imagery confirms a new uranium enrichment building at the Yongbyon complex, resembling the Kangson facility, indicating a significant expansion of enrichment capability. Activity has also spiked at Yongbyon's five-megawatt reactor, reprocessing unit, and light-water reactor. Current estimates put North Korea's warhead stockpile at several dozen, but with this new capacity, experts project it could reach 50-70 warheads in the near term. These developments suggest the regime is efficiently scaling its ability to produce weapons-grade material, combining uranium enrichment with plutonium reprocessing for a more robust program.
