IAEA identifies new two-storey uranium enrichment plant at Yongbyon

The International Atomic Energy Agency reported a newly constructed two-storey uranium enrichment facility at North Korea’s Yongbyon nuclear complex, based on satellite imagery and open-source information, the agency said on 28 August.

The IAEA assessed the building could accommodate up to 28 centrifuge cascades used for uranium enrichment. Director Rafael Grossi described the continued production of weapons‑grade material as a cause for “serious concern.”

Satellite images and state media photographs indicated leader Kim Jong Un visited a “newly inaugurated nuclear materials production factory” on 3 June, which the IAEA identified as the Yongbyon enrichment facility. The agency noted Kim praised the country’s “greatly expanded production capacity” and its potential to support “larger plans.”

The report also stated operations began in January at an expanded annex of an enrichment site in Kangson near Pyongyang, where an annex was first built in 2024. The IAEA compiled its findings from satellite imagery, open sources and state media photographs, noting it has had no inspectors in the DPRK since 2009.
