          North Korea's Nuclear Weapons:
                   How Soon an Arsenal?

Summary


     North Korea ended the eight-year freeze on its nuclear program in late 2002,
 expelling international inspectors and restarting plutonium production facilities. Before
 2002, the CIA estimated that North Korea might have enough plutonium (Pu) for 1 or
 2 weapons. Since then, North Korea may have reprocessed the 8,000 spent fuel rods
 previously under seal at Yongbyon, yielding enough Pu for 6 or 8 weapons. In 2005,
 North Korea announced it had nuclear weapons and was building more. North Korea
 reportedly shut down the small reactor in April to extract plutonium. If so, it could have
 two more weapons by April 2006. In July 2005, North Korea rejoined the Six-Party
 Talks after a 13-month hiatus and agreed in September to abandon its nuclear weapons
 program and return to the Nuclear Nonproliferation Treaty, while resuming construction
 of its two larger reactors. North Korea may continue to produce fissile material for
 nuclear weapons as long as Six-Party Talks do not bring a resolution. This report will
 be updated as needed.


 Background

    In the early1980s, U.S. satellites tracked a growing indigenous nuclear program in
North Korea. A small nuclear reactor at Yongbyon (5MWe), capable of producing about
6kg of plutonium per year, began operating in 1986.1 Later that year, U.S. satellites
detected high explosives testing and a new plant to separate plutonium. In addition,
construction of two larger reactors (50MWe at Yongbyon and 200MWe at Taechon)
added to the mounting evidence of a serious clandestine effort. Although North Korea
had joined the Nuclear Nonproliferation Treaty in 1985, the safeguards inspections that
began only in 1992 raised questions about how much plutonium North Korea had
produced covertly that still have not been resolved. In 1994, North Korea pledged, under
the Agreed Framework with the United States, to freeze its plutonium programs and

1 5MWe is a power rating for the reactor, indicating that it produces 5 million watts of electricity
per day (very small). Reactors are also described in terms of million watts of heat (MW thermal).
