in charge of a new organization independent of the PAEC tasked with producing plutonium for nuclear weapons. At that point, Pakistan had not yet completed the less difficult step of subcritical, cold testing, and would not do so until 1983 in Kirana Hills. PAEC continued its research on plutonium and built the 40–50 MW (megawatt, thermal) Khushab Reactor Complex at Joharabad. In April 1998, Pakistan announced that the nuclear reactor was operational. The Khushab reactor project was initiated in 1986 by Munir Khan, who informed the world that the reactor was totally indigenous, i.e. that it was designed and built by Pakistani scientists and engineers. Various Pakistani industries contributed in 82% of the reactor's construction. The Project-Director for this project was Sultan Bashiruddin Mahmood. According to public statements made by the US Government officials, this heavy-water reactor can produce up to 8 to 10 kg of plutonium per year with increase in the production by the development of newer facilities, sufficient for at least one nuclear weapon. The reactor could also produce if it were loaded with , although this is unnecessary for the purposes of nuclear weapons, because modern nuclear weapon designs use directly. According to J. Cirincione of Carnegie Endowment for International Peace, Khushab's Plutonium production capacity has allowed Pakistan to develop lighter nuclear warheads that would be easier to deliver to any place in the range of the ballistic missiles. PAEC also created a separated electromagnetic isotope separation program alongside the enrichment program, under Dr. G D Allam, a theoretical physicist. The plutonium electromagnetic separation takes place at the New Laboratories, a reprocessing plant, which was completed by 1981 by PAEC and is next to the Pakistan Institute of Nuclear Science and Technology (PINSTECH) near Islamabad, which is not subject to IAEA inspections and safeguards. In late 2006, the Institute for Science and International Security released intelligence reports and imagery showing the construction of a new plutonium reactor at the Khushab nuclear site. The reactor is deemed to be large enough to produce enough plutonium to facilitate the creation of as many as "40 to 50 nuclear weapons a year." The New York Times carried the story with the insight that this would be Pakistan's third plutonium reactor, signalling a shift to dual-stream development, with Plutonium-based devices supplementing the nation's existing HEU stream to atomic warheads. On 30 May 1998, Pakistan proved its plutonium capability in a
