The North Korea has several nuclear installations with the potential capacity to produce nuclear weapons. The majority of them are located at Yongbyon , to 100 km in the north of Pyongyang. The engine of Yongbyon produced the plutonium used in the first Korean nuclear test carried out in 2006. The scientific Research center Nucléaire of Yongbyon currently employs 2.000 workers.

The managing director of the IAEA declared, on July 18th, 2007, that the inspectors of the Agency had noted the closing of the totality of the five installations of the site of Yongbyon, pursuant to the agreement signed in Beijing on February 13rd, 2007 (see the detailed article Nuclear weapons in North Korea).
