North Korea has constructed a new two-storey uranium enrichment facility, prompting the head of the world’s nuclear watchdog to express “serious concern”. The International Atomic Energy Agency (IAEA) confirmed the new building is part of the main Yongbyon nuclear complex.
This development points to a steady expansion of North Korea’s sanctioned nuclear infrastructure. IAEA Director General Rafael Grossi stated that “The continuation and further development of the DPRK’s nuclear programme are clear violations of relevant UN Security Council resolutions and are deeply regrettable,” as reported by the BBC.
Expansion of Enrichment Capabilities
The newly identified two-storey building at Yongbyon is reportedly capable of housing up to 28 centrifuge cascades, which are used to enrich uranium. The IAEA first referred to the existence of the building in June, with Mr. Grossi mentioning the possibility earlier in the year.
North Korean leader Kim Jong Un reportedly visited a “newly inaugurated nuclear materials production factory” on 3 June, which the agency identified as the Yongbyon enrichment facility. According to the IAEA’s report, Kim praised the country’s “greatly expanded production capacity,” noting it would “offer the possibility of carrying out larger plans.”
Beyond Yongbyon, the IAEA’s report, published late last month, also indicated that Pyongyang has begun operating an expanded annex at another enrichment site in Kangson, near the capital. Indications suggest operations commenced there in January this year, with an annex constructed in Kangson in 2024.
International Concerns and Context
The IAEA, which has not had inspectors in North Korea since their expulsion in 2009, relies on satellite imagery for its assessments of the country’s nuclear activities.
Edward Howell, a lecturer at the University of Oxford, highlighted the challenges of monitoring North Korea’s programme. He told the BBC, “What makes North Korea’s nuclear programme so concerning is that many of its facilities are unknown, concealed, and thus difficult to target.” Howell added that “Beyond Yongbyon, we know that other facilities exist: Kangson, for instance. The embeddedness of North Korea’s nuclear doctrine within its foreign and domestic policy means that we should expect there to be more concealed production sites.”
Despite leading one of the world’s poorest countries, Kim Jong Un dedicates significant resources to developing a clandestine nuclear arsenal, with a 2022 report from a non-proliferation think-tank estimating this figure at $640 million. The North’s nuclear programme has accelerated under Kim, who has overseen a record number of missile tests, including numerous intercontinental ballistic missiles (ICBMs) since 2017. The country has conducted six nuclear weapons tests, the last in September 2017.
North Korea declared itself a nuclear power in 2022 and has vowed never to relinquish its weapons, of which it is estimated to possess dozens. South Korea’s president, Lee Jae Myung, proposed talks in August on officially ending the war between the two countries, suggesting this could also be a forum for discussing “effective ways to halt the advancement of the North’s nuclear capabilities.” Lee previously stated that Pyongyang was producing 15 to 20 more warheads annually, and had expressed support for a deal between US President Donald Trump and Kim to freeze production, as noted by Reuters in its reporting on the IAEA findings.

Since the expulsion of its inspectors in 2009, the IAEA relies on satellite imagery for its assessments of North Korea’s nuclear programme.
- What is the estimated financial investment in North Korea’s nuclear arsenal?
A non-proliferation think-tank estimated that North Korea spent $640 million on developing its nuclear arsenal in 2022.
