Pakistan's Nuclear Facilities
Chagai Hills - Ras Koh
On May 28, 1998 Pakistan announced that it had conducted five (simultaneous) nuclear weapons tests. Seismic data indicates that this was the location of the tests.
Wazir Khan Khosa
Pakistan conducted at least one underground nuclear test on May 30, 1998, in a vertical shaft at a site in the Kharan Desert, about 100 kilometers from the site of the first test.
Possible uranium enrichment research and development facility/pilot plant. Like many other sites in Pakistan, it is not subject to inspection by the International Atomic Energy Agency.
Large plutonium extraction plant, civil works complete, and a Chinese-supplied nuclear power reactor in early stages of construction.
Khan Research Laboratories, Kahuta
Kahuta is the site of the Khan Research Laboratories [KRL], Pakistan's main nuclear weapons laboratory as well as an emerging center for long-range missile development. The primary Pakistani fissile-material production facility is located at Kahuta, employing gas centrifuge enrichment technology to produce Highly Enriched Uranium [HEU]. This facility is not under International Atomic Energy Agency safeguards
Pakistan's first nuclear energy plant (heavy-water, natural uranium, 137 MWe), Karachi Nuclear Power Plant (KANUPP), became operational in 1972 under International Atomic Energy Agency (IAEA) safeguards. Built with Canadian assistance, KANUPP is a unique variant of the CANDU reactor.
Chasma Nuclear Plant
The Chashma Nuclear Power Plant project was initiated in the 1970s, and became operational in 2000.
Plutonium production reactor under construction. If completed, in conjunction with the plutonium extraction plants, it could create a significant inventory of unsafeguarded weapons-usable plutonium.
The Pakistan Institute of Science and Technology is responsible for fuel cycle research and development activities; including analytical chemistry, nuclear materials, metallurgy, fuel development. The New Labs Reprocessing Plant, a not-yet-operational plutonium extraction plant is also located here.
