New Enrichment Facilities
The IAEA said satellite imagery and analysis of open-source data, including photos and videos in official North Korean media, show that North Korea is actively expanding its nuclear program. At the main nuclear site in Yongbyon, a new two-story uranium enrichment building was constructed that can accommodate up to 28 centrifuge cascades. At the Kangson uranium enrichment plant, a large annex began operation after construction that started in 2024.
IAEA Response and Access
IAEA Director General Rafael Grossi called the development a serious concern and a violation of UN Security Council resolutions. North Korea does not recognize the IAEA's authority over its nuclear program and has not allowed inspections since 2009. North Korean authorities maintain that the country's status as a nuclear power will remain unchanged and that the IAEA has no legal right to intervene in the internal affairs of a state that has not signed the Treaty on the Non-Proliferation of Nuclear Weapons.
