North Korea still operating, improving major nuclear fuel plant, experts say

A key source of material for North Korea's nuclear program remains operational and continues to be updated, according to a coming report based on recent satellite photos that underscores the persistence of a top threat to U.S. national security. In a preview of their analysis obtained exclusively by NBC News, North Korea experts Joseph S. Bermudez Jr. and Victor Cha say imagery taken in March depicts ongoing activity at the Pyongsan Uranium Concentrate Plant, which is believed to produce so-called yellowcake uranium, a precursor of nuclear fuel. Cha, who was President George W. Bush's top Korea adviser, said the continuing work at the facility demonstrates the North Koreans' "unrelenting effort to grow their capabilities despite three summits and the utter failure of the one diplomatic negotiation that Trump has put any effort into."
