Abstract:
Several states have succeeded in extracting “yellowcake” uranium from phosphoric acid as part of the phosphate fertilizer production process. The Democratic People’s Republic of Korea (DPRK) has both the means and motivation to undertake such work, thus significantly altering existing open-source assessments of how much yellowcake uranium North Korea could produce annually, which in turn affects estimates of how many nuclear warheads DPRK can make. There is ample rationale for the DPRK to pursue this method of uranium extraction. The dual usage of existing infrastructure would both conceal the activity and make it more difficult for international audiences to positively identify and condemn. The DPRK certainly needs fertilizer, and the information on how to extract uranium from its production is readily available. Lastly, this method of yellowcake production embodies the policy of byungjin—parallel nuclear-weapon development and economic expansion—a hallmark of Kim Jong Un’s strategy. Given these factors, the rationale for the pursuit of this method is clear. The evidence is even more so. The first section of the paper explains the science behind uranium extraction from phosphoric acid produced as an intermediary in the production of fertilizer from phosphate rock. The second section highlights some of the historical cases of states using this method to obtain uranium. The third section elucidates the reasoning and rationale for using this method in the DPRK, and the fourth section examines the open-source evidence available indicating that this method of obtaining uranium—however uncommon—is in use in the DPRK today, and is likely to continue and expand in scale.

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

Content Type:
Working Paper
Institution:
James Martin Center for Nonproliferation Studies
Abstract:
Although uranium mining and milling constitute the first step in any nuclear-weapons program, nuclear nonproliferation analysts have devoted surprisingly little attention to monitoring these processes. Understanding and monitoring uranium mines and mills can provide deeper insight into fissile-material production. This report focuses on the insights gleaned from remotely sensed images of known Chinese uranium mines and mills to understand the current status of uranium mining and milling in North Korea.

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.

5. he Other Fissile Material: Strengthening National and International Plutonium Management Approaches

Abstract:
CNS Occasional Paper #42 discusses issues relating to separated, or unirradiated, plutonium in civilian nuclear programs, that is, plutonium that has been chemically separated from spent nuclear reactor fuel by reprocessing but has not been reintroduced into a nuclear reactor after separation and subjected to further irradiation. Efforts to limit the spread of reprocessing in the civilian sector crystalized in the mid-1970s. Two developments triggered the intensified attention to this issue: (1) India’s 1974 test of a nuclear explosive device, which used as its core plutonium produced in an ostensibly peaceful nuclear-research program, and (2) attempts on the part of several states that had not renounced nuclear weapons to obtain reprocessing plants for their civil nuclear power programs. In the intervening forty-four years, in those states that proceeded with civilian reprocessing programs, stocks of separated civilian plutonium have continued to grow in the aggregate. Taken together today, they are substantially greater than worldwide military plutonium stocks. Multiple approaches to limiting the separation of civil plutonium have been implemented, and still others have been given serious study, but stocks have increased regardless, while options for working down these stocks appear to be diminishing. Meanwhile, concern has deepened over the possible theft or diversion of this material, which could bring weapon-sufficient quantities of plutonium into the hands of violent extremists. International Atomic Energy Agency safeguards are valuable, but they do not fully address the risks of breakout from nonproliferation or disarmament commitments. Safeguards are intended to provide timely warning of diversion, so as to provide an opportunity for intervention. However, even if diversion of plutonium is detected immediately, the plutonium could be weaponized too quickly for effective preventive measures. Nor are safeguards designed to address nuclear-material security issues. Accordingly, there is a need for institutional and technical measures to mitigate risks from separated plutonium. This report recommends steps to address the risks posed by existing reprocessing programs and stocks as well as ways to discourage potential new programs.

Abstract:
Uranium mines and mills offer an important focus for the analysis of fissile-material production. It is possible to combine traditional research techniques with new tools and technologies to estimate the production of yellowcake uranium. Such estimates can, in turn, be used to roughly estimate the throughput of a country’s nuclear fuel cycle. In some cases, this may help researchers to determine whether undeclared fuel cycle facilities exist and to estimate their capacity. This CNS Occasional Paper is the first in a series of papers funded by the MacArthur Foundation. It deals primarily with how researchers can use open-source information to monitor uranium mining and milling in the service of arms control, disarmament, and nonproliferation goals. Additional monographs will provide regional cases studies in North Korea, China, India, and Pakistan to demonstrate what these methods can reveal—and what they cannot. The final monographs look at the emerging, and potentially revolutionary, role of remote sensing for this application and gives policy recommendations.
