North Korea boosting ability to manufacture nuclear arms, IAEA chief warns
Grossi said satellite imagery shows a new facility and rising activity at Yongbyon, signaling a significant increase in weapons-grade material output.
- On April 15, 2026, International Atomic Energy Agency Director Rafael Grossi reported a "very serious increase" in North Korea's nuclear weapons production capacity, citing stepped-up activity at the Yongbyon nuclear complex.
- Pyongyang reactivated the Yongbyon site in 2021, and the IAEA identified rapid operational increases at the facility's five-megawatt reactor and reprocessing unit, suggesting significant expansion in uranium enrichment capacity.
- According to CSIS, satellite imagery from April confirms completion of a suspected uranium enrichment plant, while experts estimate the North's nuclear arsenal totals a few dozen warheads.
- These advances complicate international monitoring and verification efforts, undermining regional security; increased fissile material production likely pushes South Korea toward closer defense coordination to counter the threat.
- Despite concerns regarding ties with Moscow, Grossi stated the IAEA has not observed "anything in particular" indicating direct Russian involvement in the North's nuclear development, suggesting self-developed advancements.

North Korea is showing a "very serious increase" in its ability to produce atomic weapons, the head of the UN nuclear watchdog said on Wednesday on a visit to Seoul. The diplomatically isolated north is believed to operate multiple facilities for enriching uranium, a key step in making nuclear warheads, South Korea's spy agency has said. They include one at the Yongbyon nuclear site, which Pyongyang purportedly decommissioned after talks but lat…
