How much WGU is in a Pakistani nuclear weapon?
Pakistan’s nuclear weapons are believed to be based on a Chinese design that has a solid core of WGU. This design need not require more than 15 kg of WGU, but a number of factors might increase this amount. A greater amount of WGU could be used to increase the weapon’s reliability or yield. It is also likely that some WGU would be lost during the weapon-production process. Therefore, ISIS has concluded that an average of 20 kg of WGU per Pakistani weapon is a reasonable estimate. Up to the end of the moratorium, therefore, Pakistan had sufficient WGU for 10 nuclear weapons, based on a central estimate of 210 kg of WGU. If Pakistan had small losses during the production process, and each weapon used an average of 15 kg of WGU, Pakistan would have had enough WGU for 14 weapons. Has Pakistan resumed WGU production? It is likely that Pakistan resumed WGU production at Kahuta many months ago. Some speculate that WGU production resumed several years ago. Information about operations at Kahut
