Located at the Pakistan Institute of Nuclear Science and Technology (PINSTECH), the New Labs Reprocessing Facility reprocesses spent fuel from Pakistan's Khushab reactors. [1]

Using technology and plans acquired from French and Belgian firms, Pakistan began constructing the New Labs Reprocessing Facility in 1980.[2] While construction was completed by 1982, the facility remained idle until spent fuel from the unsafeguarded Khushab-1 reactor could be utilized in 2000. [3]

In 2009, open source satellite imagery analysis indicated that construction had begun on an expansion of the New Labs facility; beginning in 2002 and apparently completed in 2006. [4] Originally, the New Labs facility could separate between eight and ten kilograms of weapons-grade plutonium per year. [5] Its capacity since the alleged expansion is unknown.
