The Pakistan Institute of Nuclear Science & Technology (PINSTECH) is a federally funded research and development laboratory in Nilore, Islamabad, Pakistan.^[1][2]

The site was designed by the American architect Edward Durell Stone and its construction was completed in 1965. It has been described as "[maybe] the most architecturally stunning physics complex in the world".^[3]

In response to the war with India in 1971, the lab was repurposed as a primary weapons laboratory from its original civilian mission.^[3] Since the 1990s, the lab has been focused increasingly on civilian mission and it maintains a broad portfolio in providing research opportunities in supercomputing, renewable energy, physical sciences, philosophy, materials science, medicine, environmental science, and mathematics.^[4][5]

The Pakistan Institute of Nuclear Science & Technology (PINSTECH) is one of nation's leading research and development Institution affiliated to the national security.^[6] It is a principle national laboratory that has the responsibility by ensuring the safety, security, and reliability of nation's nuclear weapons program by advancing applications in science and technology.^: 84 [7]

The PINSTECH is located in Nilore, about 15 mi (24 km) southeast of Islamabad, and was designed by the American firm, AMF Atomics and Edward Durell Stone who once worded: "This....has been my greatest work. I am proud that it looks like it belongs in this country."^{: 56–57 [7][3]}

Since owned by the Government of Pakistan, its managed by Pakistan Atomic Energy Commission.^[7] The scientific research programs are supported at the laboratory through the Pakistan Institute of Engineering and Applied Sciences, also in Nilore.^[6] The laboratory covers around 400 acres (1.6 km²) area.^[6][3]

The establishment of the Pakistan Institute of Nuclear Science & Technology (Pinstech) was embodiment of the Atoms for Peace initiative in 1953 and a long-sought initiative led by Abdus Salam who was lobbying for a professional physical laboratory since 1951.^[8] Budget constraints and lack of interests by the government administration had left a deep impression on Salam who was determined to establish to create an institution to which scientists from the developing countries would come as a right to interact with their peers from industrially advanced countries without permanently leaving their own countries.^[8] Construction of the Pinstech began when Salam who was able to find funding from the United States in 1961.^[8]

Eventually, Salam and I. H. Usmani approached Glenn T. Seaborg for the further funding of the laboratory from the United States government, which stipulated the fund if the Pakistan Atomic Energy Commission were to set up a research reactor of their own at sum of US$ 350,000.^{: 269 [9]} Contrary to United States' financial pledges, it was reported that the actual cost of building the Pinstech was neared at US$ 6.6 million ($63.8 million in 2023) that was funded and paid by the Pakistani taxpayers in 1965.^[3]

From 1965–69, the Pinstech had an active and direct laboratory-to-laboratory interaction with the American national laboratories such as Oak Ridge, Argonne, Livermore, and Sandia.^{: 269 [9][10][11]}

The scientific library of the institute consisted of a large section containing historical references and literatures on the Manhattan Project, brought by Abdus Salam in 1971 prior to start of the nuclear weapons program under Zulfikar Ali Bhutto's administration.^{: 51–100 [12]}

The Pakistan Atomic Energy Commission (PAEC) hired the laboratory's first director Rafi Muhammad, a professor of physics at the Government College University, Lahore (GCU), who affiliated the Pinstech with the Quaid-i-Azam University in 1967, bearing some special materials testing.^[13] Soon, the scientists from Institute of Theoretical Physics of the Quaid-i-Azam University had an opportunity to seek permanent research employment in physics at the laboratory.^[8]

After the costly war with India in 1971, the re-purposing of the Pinstech Laboratory was difficult since it was never intended to be a weapons laboratory.^[3] Initially, the plutonium pit production at Pinstech was quite difficult together with its tiny research reactor that could never be a source of weapons-grade plutonium.^[3] In spite of its short-comings, the investigations and classified studies on understanding the equation of state on plutonium was started the physicists at the Pinstech laboratory in 1972.^[3] The Pinstech laboratory became a main research and development laboratory when it initiated its ingenious program for the production of plutonium oxide (plutonia) and uranium oxide (Urania) in 1973.^{: 106 [7]}

The Pinstech laboratory was also a learning center for gaining expertise in nuclear fuel cycle which it provided training to other facilities after learning the very basic knowledge from the European industries prior to 1969.^[3] At the Pinstech laboratory, a pilot plant (New Labs) was built for reprocessing spent reactor fuel into plutonium pit production.^[3] Besides its fundamental and basic programs on physical sciences, the laboratory provided a ground for the Pakistani scientists to design and engineer weapon designs, with many feared that India was rapidly developing a nuclear bomb.^[7]

As Nilore became restricted site, the research efforts were directed towards working on understanding and producing first the reactor-grade plutonium and eventually to military-grade plutonium from the spent fuel rods by undergoing a chemical process, "reprocessing".^{: 138 [7]} The design work had carried out on 20 different laboratories at the lab, and it was its New Labs facility of the lab that was able to produce the first batch of the weapon grade plutonium of ²³⁹Pu by 1983.^{: 191 [7]} This weapon-grade plutonium was the source material that was carried on a nuclear test conducted at the Ras Koh Range on 30 May 1998.^{: 205 [7]}

The scientists at the Pinstech laboratory initiated the studies on understanding the ingenious nuclear fuel cycle in spite of having basic familiarity.^{: 115 [7]} In 1973, the lab conducted several studies on understanding the properties of uranium oxide, eventually producing the first fuel bundle in 1976 that was shipped to the Karachi Nuclear Power Plant to keep its grid operations running.^{: 106 [7]} The Pinstech also took initiatives in learning and understanding the chemistry of uranium hexafluoride, which the technology was transferred to the Islamabad Uranium Conversion Facility in 1974.^{: 115–116} In addition, the understanding of UF6 eventually led in producing the Zircaloys, which it was also produced at the lab first; and later having it transfer the technology to the Kundian Nuclear Fuel Complex in 1980.^{: 115–116}

As of today, PINSTECH has been shifted to peacetime research in medicine, biology, materials and physics. Its Molybdenum-42 facility was used to medical radioisotopes for treating cancer. Scientists from Nuclear Institute for Agriculture and Biology (NIAB) and Nuclear Institute for Food and Agriculture (NIFA) had been using the PINSTECH facilities to conduct advanced research in both medical and food sciences.

Since its repurposing in 1972, the Pinstech laboratory conducts research into understanding the equation of state of plutonium, its phase diagrams, and its properties.^{: 200 [7]} In 1987, the Pinstech developed a technology by fabricating a Chromium kF39 and developed an innovative technique, "in-stu leaching", which allowed the extraction of actinides from the uranium ore without the need for conventional milling.^{: 113 [7]}

The computer scientists at the Pinstech Laboratory had built a supercomputer based on the vintage IBM computer architecture that allowed the physicists at the Pinstech to model the behavior of plutonium without the actual nuclear testing.^{: 176 [7]} Research work on plutonium is conducted at its special-purpose facility, the New Laboratories, where the weapon-grade nuclear explosives are designed and manufactured.^[3] Much of the work on plutonium is, however, is subjected to classified information.^[3]

The Centralized Analysis Facility (CAF) has been utilized chemistry on plutonium and other areas of actinides sciences are studied and conducts experiments at the Central Diagnostic Laboratory (CDL); both of labs are the most potent facilities in Pakistan.^[3]

Besides its national security mission, the lab promotes applications of radiation and isotope technology in various scientific and technological disciplines to support the nation.^[3] It is also working on important non-nuclear fields, which are crucial for the development of science and technology in the country. In 2020, expansion work was started at Pinstech lab to help its "ability to produce isotopes for medical use, especially for preparation of radiopharmaceuticals for cancer patients while also helping the country in its aspirations in other applications of peaceful use of nuclear technology."^[1]
