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:
Over the last forty years, South Korea (or the Republic of Korea, or ROK) and the United States have become essential partners on nuclear matters. The United States provided the technology and knowhow necessary for Korea to establish a nuclear sector. Koreans mastered that technology and have worked to improve on it, with the twin goals of expanding their country’s energy independence and becoming a leading exporter of nuclear power production facilities. The two states’ nuclear energy industries have become intertwined. They cooperate on multiple initiatives to strengthen international nuclear security and nonproliferation measures. Collaborative research ties amongst nuclear scientists from both countries run deep. Arguably, each state is the other’s most important nuclear partner. As with all maturing relationships, there remain differences of view and priority that must be managed. Though unlikely, a disruption in ROK-US nuclear relations would have wide-ranging, deleterious effects on both states. For this reason, the conclusion in June 2015 of a new bilateral treaty, the Agreement for Cooperation Between the Government of the United States of America and the Government of the Republic of Korea Concerning Peaceful Uses of Nuclear Energy (hereafter referred to as the 123 agreement after section 123 of the Atomic Energy Act, the relevant US statute) is a critical milestone. The new agreement establishes the terms for nuclear cooperation for the next twenty years. It is expansive and forward-looking, providing the basis for unusually broad and deep nuclear ties. The 123 agreement will bring predictability to the relationship at a time when the global nuclear energy outlook remains in flux. However, the new nuclear agreement only managed to partially resolve several deep-seated differences between the two sides that were illustrated by the fact that negotiations on a new agreement lasted more than four years and required an extension to complete. The agreement creates a new political framework for managing divergent views over how to cooperate most effectively, but differences may yet re-emerge and frustrate cooperation. The challenge before the two governments now is to implement the new agreement in ways that can either resolve or remove these differences and solidify existing ties. In other words, the two countries should seek to build a nuclear partnership in deed, not just in word. This report articulates a vision for ROK-US nuclear partnership for the next two decades, a period which aligns with the duration of the new agreement for cooperation. It highlights challenges and opportunities and provides recommendations intended to deepen and expand the range of existing cooperation in ways that will support a stable and sustainable nuclear partnership. The objective of the report is to describe a desirable and stable end-state for the relationship—an enduring partnership—and to identify steps along the path to achieve it. It discusses multiple areas of cooperation, assesses strengths and weaknesses of existing ties, and identifies practical activities both parties can pursue toward building the partnership.

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.

4. US and Russia Can End Use of Weapons-Usable Uranium for Medical Uses

Abstract:
A new report co-authored by CNS Senior Research Associate Miles Pomper recommends steps for the United States and Russia to cooperate in ending Russian use of highly enriched uranium (HEU) in medical isotope production, an important step in keeping this nuclear weapons material from terrorists. Great progress has been achieved in recent years in minimizing civilian use of HEU as part of the international efforts to reduce the nuclear terrorism threat. In particular, the leading global suppliers of the molybdenum-99 (Mo-99) isotope, which is widely used in medical diagnostics, are taking steps to reduce and, in the medium time frame, completely eliminate the use of HEU in the production of medical isotopes. Major new steps towards phasing out HEU use in medical isotopes production could be announced at the Nuclear Security Summit that will take place in The Hague on March 24-25, 2014. The Russian nuclear industry has set for itself an ambitious goal of becoming one of the three top global suppliers of Mo-99, used in 80 per cent of the medical procedures involving isotopes particularly as a diagnostic tool. Growing Russian production could help stabilize the global Mo-99 market, which faced severe shortages on several occasions in 2005-2013. According to some estimates, in 2010 during a six month period medical facilities around the world were unable to perform diagnostic procedures for several million people due to the shortage of Mo-99; the shortfall was estimated at 7 million doses. However, until recently, Russia had been bucking global trends by planning to use HEU fuels and targets rather than safer low enriched uranium (LEU) for much of this production. The ‘Ending HEU Use in Medical Isotope Production: Options for Russian-US Cooperation’ report co-authored by the Moscow-based Center for Energy for Energy and Security Studies (CENESS) analyses what can be done by Moscow and Washington to harmonize the Russian producers’ plans to win a share of the global market, while at the same time facilitating the Russian nuclear industry’s transition to new market requirements for producing Mo-99 without HEU.
