In June, ISIS said North Korea might possess nuclear weapons small enough to be loaded onto Rodong ballistic missiles, whose range can reach any part of Japan.
In Yongbyon, a 50,000-kilowatt graphite-moderated reactor is scheduled for construction. However, work on the reactor, whose power output is 10 times greater than the current experimental reactor, has been suspended for unknown reasons. If the reactor is built, North Korea will be able to extract enough plutonium to make 10 nuclear weapons annually.
In addition, according to some reports, construction of a 200,000-kilowatt nuclear reactor is planned at Taechon, in the west of Yongbyon.
If both reactors are built, North Korea could produce enough plutonium to make 50 nuclear weapons annually.
