North Korea is operating a modern uranium enrichment plant equipped with "thousands" of centrifuges, the state-run Rodong Sinmun daily said Tuesday.
It was the first time the North Korean media referred to the uranium centrifuges since the North showed a plant in Yongbyon to U.S. nuclear scientist Siegfried Hecker.
The claim came in an article discussing the "global trend" to develop and use nuclear energy for peaceful purposes.
The article said a light-water nuclear reactor is being built and that uranium enrichment is taking place to fuel it. Around 2,000 centrifuges can enrich enough uranium for one to two nuclear warheads a year.
