Page 135 from FCO 372113 - the Nuclear policy of Pakistan 1978

The document highlights various aspects of Pakistan's nuclear development capability. It mentions that Pakistan requires a 4-5 year period for completion of the project and estimates that a plant of 10,000 centrifuges could produce 50kg of highly enriched uranium per year. The document also refers to Pakistan's pilot-scale plant for uranium reprocessing and plans for a larger capacity plant, but lacks specific information about their status. It acknowledges a gap in knowledge regarding the construction or purchase of uranium hexafluoride production facilities. While the document suggests that Pakistan could acquire enough fissile material for a single device by 1981 at the earliest, it also notes that the extent of Pakistan's activities and the probability of them achieving a weapons capability remain uncertain.
