North Korea has unveiled a new facility to produce nuclear bomb fuels and Kim Jong Un has paired that disclosure with a pledge to expand the country’s nuclear forces at an exponential rate. Kim visited the site on Wednesday, then said he and other top officials had confirmed the order of priority for carrying out an ambitious future plan to strengthen the arsenal.
The timing matters because the facility was disclosed on Thursday, giving Pyongyang another public look at the machinery behind its nuclear program just as Kim is pressing for a bigger one. In photos released by state media, he walked through narrow aisles lined with dense rows of silver tubes and pipes, a staged tour that was meant to project industrial scale and momentum rather than secrecy.
South Korea’s Joint Chiefs of Staff assessed the site as a uranium enrichment plant and said it was closely coordinating with the United States to monitor North Korean nuclear activities. State media said the facility used more sophisticated technology, but it did not give the location. Another image showed Kim speaking with senior officials in a meeting room, where a blurred graphic depicting a cone-shaped object was spread across a table, though it was not immediately clear whether the graphic showed a warhead design.
The disclosure was the third time North Korea has revealed a uranium enrichment site. It follows photos of another covert uranium-enrichment plant released in 2024 and an earlier appearance of a uranium-enrichment plant at the main Yongbyon nuclear complex before visiting American scholars in 2010. Last September, South Korean Unification Minister Chung Dong-young said North Korea was operating four uranium enrichment facilities, including Yongbyon, and that they were running every day.
Kim said the need to bolster the country’s nuclear war deterrent in quality and quantity had grown because of confrontations with what he called the “most ferocious enemies.” He also said exercising the position of a nuclear weapons state was North Korea’s “invariable” stand. Experts say he wants international recognition as a nuclear state so he can demand the lifting of U.N. economic sanctions, and eventually use arms-reduction talks with Washington to win concessions in exchange for only a partial surrender of his nuclear capability.
There is still a gap between North Korea’s display of industrial capacity and what it can actually field. Some experts question whether it has functioning nuclear missiles that can reach the U.S. mainland, even as Kim keeps vowing to exponentially expand the arsenal. President Donald Trump has repeatedly said he wants to resume diplomacy with Kim, but the North Korean leader has made clear that the United States must first drop its demand for denuclearization as a precondition for talks. Since their first round of nuclear diplomacy collapsed in 2019, Kim has answered with a provocative run of weapons tests, and this latest unveiling suggests he is not easing up.
