Abstract:
The mining and milling of uranium does not generally receive the attention that the subject deserves. Yet this overlooked aspect of the nuclear fuel cycle can offer analysts important clues about a country’s fissile-material production. This, in turn, helps inform highly sensitive inquiries, such as estimates of arsenal size and potential for growth. Geospatial technology is uniquely helpful as a discovery and verification tool. The production of fissile material is often a closely held state secret; even for states that report production levels to the International Atomic Energy Agency, these numbers can be difficult to verify. Remote-sensing technology, such as satellite imagery paired with change-detection algorithms, can help pierce the veil of state secrecy and overcome physical barriers to inform analysts about this vital first step in the nuclear fuel cycle. Occasional Paper #44—the final installment in a four-part series that uses open-source remote-sensing data to identify and monitor uranium mining and milling activities—examines these new tools and technologies in detail to demonstrate how analysts use them to detect, estimate, or verify uranium production. It explores different remote-sensing techniques and their various advantages, including traditional optical imagery, multispectral and hyperspectral images, and thermal and near-infrared images. It also discusses machine-learning algorithms as another tool for analysts examining large quantities of geospatial information in a relatively short amount of time. Though these technologies hold great promise for WMD analysts, there are limitations to their use. CNS Occasional Paper #44 discusses these current and future limits, and concludes by calling for increased collaboration between the commercial satellite industry and analytical organizations and verification regimes alike, as a way f

Abstract:
CNS Occasional Paper #41 details existing and potential uranium mines and mills in India and Pakistan as part of an ongoing project to track uranium production in Asian states that possess nuclear weapons. As non-signatories to the Treaty on the Non-Proliferation of Nuclear Weapons, India and Pakistan face challenges procuring fissile material from foreign sources. Both countries have ongoing nuclear-weapon programs, clear and increasing demands to supply their nuclear-energy programs, and domestic production deficits. The continuing and increasing demand for uranium in India and Pakistan indicates that domestic uranium production is likely to grow significantly in the near future. This paper explores remote-sensing techniques that can allow open-source analysts to monitor and track front-end uranium production activity in these countries. India and Pakistan both have plans to expand their nuclear-energy industries, increasing both countries’ demands for uranium. However, without membership in the NPT, both countries face a multitude of challenges to importing uranium. They are not entitled to receive nuclear-related technologies from nuclear-weapon states, nor are they allowed to trade nuclear materials with any NPT states parties. This leaves only non-signatory countries as possible trading partners: Israel, North Korea, and South Sudan. Pakistan has a history of trade with North Korea through the now-defunct A.Q. Khan network. Both India and Pakistan are expanding existing uranium mines and mills and funding exploratory research into new sites for uranium-resource exploitation. Both countries still rely heavily on domestic production of uranium resources, which allows analysts to gain significant insight into their nuclear capabilities by monitoring domestic uranium-production sites. The operational output of a mine or processing plant can be gauged by weighing numerous factors, including the amounts of vehicle traffic, construction on the site, tailings and waste piles, and changes in the surrounding environment.
