Abstract:
Additive Manufacturing (AM)—also known as 3D printing—is a rapidly emerging technology with growing relevance for the proliferation of weapons of mass destruction (WMD) and their means of delivery. The rapid pace of AM development makes it increasingly difficult to keep track of AM’s potential effect on proliferation pathways. So far, studies addressing the issue have mainly focused on nuclear proliferation. This has created two major problems for policy makers. First, by the time governments are able to respond to specific AM-induced proliferation risks, those risks might already have been overtaken by newer developments. Second, by focusing on nuclear proliferation pathways, governments can fail to recognize AM’s relevance to other proliferation modalities, including chemical and biological weapons and, especially, the means of WMD delivery. This report addresses these shortcomings. As an innovative pilot study, this report provides a more comprehensive approach toward explaining latest AM developments and mitigating the risk of WMD proliferation. Effectively, this report is the first beyond-the-horizon assessment of the impact of AM developments not only on potential nuclear-weapons programs, but also on other WMD modalities and their delivery systems. For this project, Negotiation Design & Strategy (NDS) assembled an expert team of well-known AM and nonproliferation specialists from Germany, the United States, and the United Kingdom—three countries at the forefront of AM development. The research team’s contextual knowledge of AM facilities in Europe and the United States allowed for in-depth, on-the-ground interviews with US and European experts from the private sector, national laboratories, and research institutions. Interviews were augmented with an analytical deep dive into the latest AM developments, based on open-source technical literature, including academic papers and patents. The final report allows us to better forecast technological developments and raise awareness for the critical role that AM plays in international security. This report also demonstrates the importance of emerging technologies in the nonproliferation field and underscores the need for further research of this kind. Studies such as this are crucial to inform the broader examination of the relationship between technology and international security.

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.

3. Improving the Security of All Nuclear Materials

Abstract:
About four-fifths of the weapons-usable nuclear materials in the world are in non-civilian programmes. This means not only as the explosive core in active or reserve nuclear weapons, but also as fuel in naval and military research reactors, highly enriched uranium (HEU) and plutonium at production sites, in storage, or declared excess to military uses, but not yet transferred to other programmes or eliminated. Yet coordinated global efforts to enhance the security of nuclear materials have been almost exclusively concentrated on the estimated 17% of such nuclear materials in the civilian sector. Ideally, all HEU and plutonium of the same grade should have at least the same level of adequate security regardless of the possessor or purpose, since the materials pose the same threat. In practice, however, the security of materials can vary depending on whether they are used in the civilian or military sectors. The Convention on the Physical Protection of Nuclear Material and Nuclear Facilities (CPPNMNF – as the Convention on the Physical Protection of Nuclear Material was renamed after the 2005 amendment came into force in May 2016), as well as International Atomic Energy Agency (IAEA) security guidelines such as INFCIRC/225/Rev.5, describe how civilian materials should be secured. No such explicit guidelines exist on how to secure materials outside of the civilian sector. Nor is there comprehensive public knowledge about the state of security of such materials in all countries with nuclear weapons programmes. It has often been asserted that nuclear materials in non-civilian use are well protected because they are under military control. However, the number of troubling security breaches involving nuclear material in military use, as well as some examples involving civilian nuclear facilities, belies this casual assumption, underscoring why the world should not simply accept the unsubstantiated ‘solemn word’ of authorities that security is as tight as needed. The list of incidents includes insider threats, peaceful incursions for demonstration purposes, theft, armed attack, and, most recently, over-flights by drones and computer hacking. Our report includes a number of examples of incidents at civilian facilities as well because they demonstrate areas of vulnerability that may also apply to the noncivilian sector. The record offers a compelling case for why security must be enhanced for all nuclear material.

Abstract:
Highly enriched uranium (HEU)—one of the key ingredients for nuclear weapons—is one of the most dangerous materials on the planet. Significant progress has been made over the past several years to eliminate all HEU from 26 countries and Taiwan. The creation of regional HEU-Free Zones would help cement a global norm against civilian HEU use in much the same way that Nuclear-Weapon-Free Zones have strengthened global non-proliferation and disarmament efforts. In many cases, only one or two countries in each proposed regional HEU-Free Zone have small amounts of remaining HEU, presenting an opportunity for countries to take action prior to the Nuclear Security Summit in 2016. This concept paper was developed by a working group on “The Elimination of Highly Enriched Uranium in Civilian Applications,” a project of the Fissile Materials Working Group, a coalition of eighty civil society organizations committed to improving fissile materials security. Initial work on the concept was also funded by the Nuclear Threat Initiative.

Abstract:
Permanent Risk Reduction of Radioactive Sources Illustration by Evelyn Helminen, MIIS There has been a marked increase in international and domestic attention to the need to replace high-risk radioactive sources with less risky and non-isotopic alternatives in order to forestall an act of radiological terrorism. In response to this need, the James Martin Center for Nonproliferation Studies at the Middlebury Institute for International Studies at Monterey, with the support of the US and UK governments, hosted three, closed-door workshops with governmental and nongovernmental experts in Washington, London, and Vienna to propose appropriate policies. Through these workshops and additional research, CNS has developed the new occasional paper, “Permanent Risk Reduction: A Roadmap for Replacing High-Risk Radioactive Sources and Materials,” which offers a series of actions that governments could take to help expedite and encourage the substitution of high-risk sources with non-isotopic alternatives as an important contribution to the nuclear security framework.

Abstract:
There is growing global awareness of the need to secure radiological sources in order to prevent terrorists from using such materials in a radiological weapon, such as a “dirty bomb.” A new CNS report calls for a move towards permanently reducing this threat by substituting non-isotopic alternatives for these sources in civil uses. As an initial step, the authors propose a move towards gradual phase-out of cesium chloride use in pre-transfusion blood irradiation on a global scale – a domain where non-isotopic alternatives are considered to be the most viable in the short-term. They urge United States to launch an international initiative involving the phase out of cesium-chloride and other high-risk radiological sources as a “gift basket” for the upcoming 2014 Nuclear Security Summit. Cesium chloride is one of the most commonly used radiological materials, despite being an IAEA Category 1 “extremely dangerous” source. Because cesium chloride is easily dispersible, water soluble, and relatively easy to handle, it is particularly suitable for terrorist purposes. The blood irradiators that use it as a source are located in many large hospitals and blood banks (inherently publicly accessible spaces), and the source is usually transported through regular civilian infrastructure at the beginning and the end of its lifecycle, giving more cause for concern. Cesium chloride based irradiators are used to treat blood and blood products prior to transfusion in order to prevent a rare but fatal Graft Versus Host Disease (GVHD). A growing number of non-isotopic alternatives are becoming available for that purpose, but there is a serious lack of awareness about the range of options and how they compare to current practices, both among the medical professionals and national regulators.
