"In December 2002, North Korea ended the 8-year-old freeze on its nuclear program by expelling inspectors and reopening its plutonium production facilities. The CIA assessed that North Korea could produce 5-6 weapons by mid-2003, in addition to 1 or possibly 2 weapons it might already have. In April 2003, North Korean officials claimed they had completed reprocessing all 8000 spent fuel rods (containing enough plutonium for 5-6 weapons), a claim which few believed. Since then, however, there are indicators that some reprocessing has occurred. This report, which will be updated as warranted, describes North Korea's steps in producing plutonium nuclear weapons."
