The think tank said images of the uranium enrichment facility at Yongbyon could also indicate operation of centrifuges that could be used to increase North Korea’s stock of enriched uranium, its other source of bomb fuel. There were signs too of at least short-term activity at North Korea’s Experimental Light Water Reactor that could be cause for concern, 38 North said. North Korea manufactures atomic bombs using uranium and plutonium and has tested five nuclear bombs. Pyongyang said its penultimate test in January 2016 was of a hydrogen bomb, something experts have treated with skepticism. Experts at 38 North estimated in April that North Korea could have as many as 20 nuclear bombs and could produce one more each month.
