Once in full operation, which could take years, the Yongbyon nuclear reactor would enable North Korea to produce 6 kilograms of plutonium a year to add to its nuclear weapons stockpile.
While all things in North Korea are cloaked in secrecy, it appears that this new reactor could produce material for nuclear weapons – potentially expanding North Korea's small stockpile.
One of North Korea's more worrisome threats this week was to restart its plutonium production reactor at Yongbyon. Satellite photos suggest the rebuilding has already begun.
North Korea said Tuesday it would restart a nuclear reactor capable of making fissile material for bombs. At least one expert sees it as North Korea's 'most worrisome' threat yet.
Once completed, the North Korean reactor would be able to produce enough plutonium for a new bomb every year, according to the US-Korea Institute at Johns Hopkins University.
