May 1, 1972: A. Q. Khan Starts Work for Dutch Nuclear Company, Obtains Classified Information despite Lacking Proper Clearance

A. Q. Khan starts work for an engineering company called Physical Dynamics Research Laboratory (FDO), which is based in the Netherlands. He obtains the job, evaluating high-strength metals to be used for centrifuge components, through a former university classmate and a recommendation from his old professor, Martin Brabers. FDO is a subcontractor for a company called Urenco. Urenco owns an enrichment facility and was established in 1970 by the governments of Britain, West Germany, and the Netherlands to manufacture top-quality centrifuges that can be used to produce highly-enriched uranium for use in power plants and nuclear weapons.
Khan Obtains Security Clearance - Khan obtains a security clearance with minimal background checks because he tells investigators he intends to become a Dutch citizen. However, he finds that security is lax and he has access to areas that should be denied him. For example, less than a week after he is hired, he visits the centrifuges, although he does not have clearance to see them. He obtains access to data about them and is also asked to help translate sensitive documents, as he has lived in various European countries and can speak several languages. Khan is allowed to take the documents home, even though this is a clear violation of security protocols. [Armstrong and Trento, 2007, pp. 46-7]
Studied in Europe, Developed Network of Contacts - Prior to being hired by FDO, Khan had studied in Europe for some time. First he attended a series of lectures about metallurgy at the Technical University in West Berlin in 1962, then obtained a master’s degree in engineering from Delft Technical University in the Netherlands in 1967, and received his doctorate from the Catholic University of Leuven in Belgium in 1971. His studies in Europe will later turn out to be useful when he starts a nuclear smuggling ring. Authors David Armstrong and Joe Trento will comment, “Along the way the affable Pakistani had developed a wide range of contacts, including individuals who would later emerge as part of his smuggling network.” [Levy and Scott-Clark, 2007, pp. 22-25; Armstrong and Trento, 2007, pp. 46-7]
