IAEA Chief Sounds Alarm Over North Korea’s Rapid Nuclear Weapons Build-Up

The Director General of the International Atomic Energy Agency (IAEA), Rafael Grossi, has warned that North Korea is recording a “very serious increase” in its capacity to produce atomic weapons.

Grossi made the disclosure while addressing reporters in Seoul on Wednesday during a visit to South Korea. He pointed to fresh signs of stepped-up activity at the Yongbyon nuclear complex, the country’s main nuclear hub.

According to the IAEA boss, periodic assessments have confirmed a rapid rise in operations at the Yongbyon 5-megawatt reactor, its reprocessing unit, and the light-water reactor. Other facilities outside the main site have also been activated, he added.

Satellite imagery and open-source intelligence further show that Pyongyang has completed construction of a new building at Yongbyon that closely resembles its known uranium enrichment halls. Analysts say the external features point to a major boost in the country’s ability to produce weapons-grade material.

Grossi said all these developments “point to a very serious increase in the capabilities of the DPRK in the area of nuclear weapons production, which is estimated at a few dozen warheads.” DPRK is the official name of the Democratic People’s Republic of Korea.

South Korea’s intelligence agencies have long maintained that the reclusive state runs multiple uranium enrichment facilities. Yongbyon itself was supposedly decommissioned years ago during diplomatic talks but was reactivated in 2021, defying international pressure.

North Korea has been under heavy United Nations sanctions since its first nuclear test in 2006. The country has repeatedly tested missiles and conducted underground nuclear explosions despite global condemnation.

The IAEA has had no direct access to North Korean sites since inspectors were expelled in 2009. Grossi stressed that the agency now relies heavily on satellite monitoring and other technical means to track the programme.

NaijaChoice News reports that the development has renewed fears of nuclear proliferation on the Korean peninsula and beyond. For Nigeria and other African nations that signed the Pelindaba Treaty making the continent a nuclear-weapon-free zone, such escalation serves as a reminder of the need for stronger global non-proliferation efforts.

The warning comes weeks after Grossi discussed Nigeria’s own plans for peaceful nuclear energy during talks in Abuja. While Nigeria continues to pursue atomic power for electricity generation under strict IAEA safeguards, the North Korean situation highlights the thin line between civilian and military nuclear ambitions.

Regional tensions remain high. South Korea and its allies have stepped up joint military drills, while Pyongyang has grown closer to Russia and China in recent years.

Grossi urged the international community to remain vigilant. Without access to the sites, he said, exact production figures are difficult to calculate, but the trend is unmistakable.

Analysts believe the fresh enrichment capacity could allow North Korea to expand its arsenal significantly in the coming years if left unchecked.

The United Nations Security Council, where Nigeria has served in the past, continues to monitor the situation closely. No immediate new sanctions were announced following Grossi’s briefing.
