North Korea appears to have taken steps to conceal upgrades to an uranium-enrichment plant from spy satellites, as it reopens communications with South Korea’s pro-engagement president, Moon Jae-in.
Satellite imagery shows that previously reported construction in an area at the Yongbyon uranium enrichment plant has been covered to hide details of the building’s layout, the U.S.-based 38 North website said in a post. It added that although there may be several reasons for the expansion, one could be to increase production of fissile material.
"One option, assuming that North Korea is producing low-enriched uranium at two enrichment halls, is that the extension could also be used to enrich low-enriched uranium to weapons grade (high-enriched uranium) as it becomes available from those two cascade halls,” it said.
