North Korea can get all the uranium it needs for nuclear weapons through its existing Pyongsan mill, and satellite imagery of tailings piles suggests the country can produce far more nuclear fuel than it is, a new academic study concludes, Trend reports citing Reuters.
Despite a self-imposed moratorium on nuclear weapons tests since 2017, North Korea has said it is continuing to build its arsenal, and this year it appeared to have restarted a reactor that is widely believed to have produced weapons-grade plutonium.
According to research published last month in the journal Science & Global Security by researchers at Stanford University and an Arizona-based mining consulting company, North Korea may be able to increase production, and has no need for other uranium mills.
"It is clear that the DPRK appears to have substantially more milling capacity than it has been using to date," said the report, using the initials of North Korea's official name, the Democratic People's Republic of Korea. "This means that the DPRK could produce much greater quantities of milled natural uranium if desired."
The Pyongsan Uranium Concentration Plant and its associated mine are North Korea's only publicly acknowledged source of yellowcake, or uranium ore, according to analysts.
The report comes as other satellite imagery shows North Korea is building a large expansion at its Yongbyon nuclear reactor, which analysts say may be used to produce weapons-grade uranium.
