A apical South Korean authoritative said connected Thursday (September 25, 2025) that North Korea is operating a full of 4 uranium enrichment facilities, adding to extracurricular assessments that it has aggregate covert atomic plants on with the wide known tract adjacent the superior of Pyongyang.
The North's person Kim Jong Un has called for a accelerated enlargement of his country's atomic weapons programme and precocious said helium would ne'er marque the arms a negotiating constituent successful effect to overtures by U.S. President Donald Trump.
The South’s Unification Minister Chung Dong-young said uranium enrichment centrifuges astatine the 4 facilities — which would see the known tract astatine Yongbyon, astir 100 kilometres (60 miles) northbound of Pyongyang — are moving mundane and stressed the urgency to halt the North’s atomic program.
Mr. Chung did not elaborate further connected the determination of the other, undeclared atomic sites. He spoke astir the North with section reporters, according to his Ministry.
Mr. Chung cited an appraisal that the North possesses 2,000 kilograms (about 4,400 pounds) of highly enriched uranium. He archetypal said that was based connected quality but the Ministry aboriginal clarified it was attributed to civilian experts.
If confirmed, the magnitude would besides awesome a crisp summation successful North Korea's stockpile of atomic material.
In 2018, Stanford University scholars, including atomic physicist Siegfried Hecker who had antecedently visited the Yongbyon complex, said the North had astir 250 to 500 kilograms (550 to 1,100 pounds) of highly enriched uranium, capable for 25 to 30 atomic devices.
Nuclear weapons tin beryllium built utilizing either highly enriched uranium oregon plutonium, and North Korea has facilities to nutrient some astatine Yongbyon. Last year, North Korea released photographs of what it said was a uranium enrichment facility, the archetypal specified disclosure since it showed the 1 astatine Yongbyon to Hecker and others successful 2010.
The determination and different details of the installation successful the photographs stay unknown.
Foreign experts judge North Korea has built further uranium-enrichment sites arsenic Mr. Kim has been pushing hard to grow his atomic arsenal.
A plutonium works is typically ample and generates overmuch heat, making it easier for outsiders to observe than a uranium enrichment plant, which is much compact and tin beryllium easy hidden from outer cameras. Centrifuges to enrich uranium tin beryllium clandestinely operated underground.
It's astir intolerable to independently corroborate however galore atomic weapons North Korea has manufactured, based connected atomic fissile materials it has produced astatine Yongbyon and elsewhere.
In 2018, a apical South Korean authoritative told parliament that North Korea was estimated to person already manufactured 20-60 atomic weapons, but immoderate experts accidental the North apt has much than 100. Estimates of however galore atomic bombs North Korea tin adhd to its arsenal each twelvemonth vary, ranging from six to arsenic galore arsenic 18.
International diplomacy connected ending North Korea's atomic programme has stalled since 2019, erstwhile high-stakes summitry betwixt Kim and Trump fell isolated without immoderate agreement.
At the time, Kim offered to dismantle the Yongbyon analyzable if helium won extended sanctions relief. But the American broadside rejected his proposal, due to the fact that it would beryllium a constricted denuclearization measurement that would permission North Korea’s other, already built atomic weapons and atomic facilities intact.
Kim has since shunned immoderate diplomacy with the U.S. and South Korea and focused connected moving weapons tests and perfecting atomic missiles that people his rivals.
Since returning to office, Mr. Trump has repeatedly expressed hopes of restarting talks with Mr. Kim. Earlier this week, Kim said helium inactive has bully memories of Mr. Trump but urged the U.S. to driblet its request that the North surrender its atomic arms arsenic a precondition for resuming long-stalled diplomacy.
Analysts measure that Mr. Kim would apt comprehend an enlarged atomic arsenal arsenic a root of greater leverage successful imaginable talks with the U.S.
They accidental that successful immoderate imaginable negotiations, Mr. Kim would again question to triumph sweeping sanctions alleviation and improved ties with the U.S. successful instrumentality for a partial surrender of his atomic and rocket programs.
