Pakistan is seen as building fourth plutonium production reactor

Institute for Science and International Security obtained new satellite images of the Khushab site in Pakistan that indicate that construction of a fourth plutonium production reactor might be underway there. In February 2010 IPFM reported that the second reactor at Khushab began operations. Construction of a third reactor began in 2005. According to the new ISIS report, the third reactor does not seem to be operational yet.
