The break-up of the Soviet Union resulted in conditions that focused attention on the possible risk of "loose nukes."  But the risk from insecure nuclear materials is not limited to the former Soviet Union; there is a need to ensure adequate physical protection on a global basis. 

The Cox Commission of the U.S. Congress was established in June 1998 to investigate concerns over Chinese acquisition of sensitive U.S. missile and space technology in connection with the launching of U.S. civilian satellites using Chinese launchers on Chinese territory. The investigations were broadened in October 1998 to include alleged security problems and possible espionage at the U.S. nuclear weapons laboratories. Some conclusions were released in January 1999 by the White House together with the administration's response. The full declassified (redacted) version of the report of the Cox Commission was released on May 25, 1999.

The decade of the 1990s has seen renewed concerns over nuclear proliferation, both horizontal and vertical. While many in the arms control community focus on numbers, it is control that is the most important factor--the detonation of just one nuclear weapon would be an international catastrophe. Rather than concentrating on numbers, the regime defined herein centers on enhancing the safety and security being provided nuclear weapons and weapons-usable fissile materials. The proposal in the paper is called the Nuclear Weapons Control Treaty (NWCT) and referred to as New Court. The emphasis is on control rather than disarmament, protection from unintended or unauthorized use rather than elimination. New Court, once in place, would provide an environment in which the necessary audits and accountability for undertaking dramatic reductions in the numbers of weapons and the quantities of weapons-usable materials could be made with much greater confidence than exists today. However, it will be decades (if ever) before the number of nuclear weapons goes to zero. In the meantime, it is paramount that comprehensive safety and security be established and maintained.

There are currently more than a thousand metric tons of civilian fuel cycle plutonium, mostly in spent fuel rods, but hundreds of tons are already separated and in storage. Any of this plutonium could be fashioned into a nuclear explosive. There are no practical approaches for disposing of plutonium in periods of time less than decades. Much of the architecture and technology from New Court can be applied to the development of international monitored storage facilities (IMSF) for civil nuclear material. The paper outlines the five key requirements an international depository must satisfy: national security for the depositors and the host nation; safety and security of the material; transparency of operations; technology transfer to provide uniform global protection; and precise accurate accountability of the quantities and forms of material deposited. The synergism and conflict among the factors is briefly described. The paper also contains annexes on the current status of some key monitoring technologies and a description of an international "stored weapons standard" for protecting weapons-usable fissile material.

Background: In the 1980s, many medical organizations identified the prevention of nuclear war as one of the medical profession's most important goals. An assessment of the current danger is warranted given the radically changed context of the post–Cold War era.

Methods: We reviewed the recent literature on the status of nuclear arsenals and the risk of nuclear war. We then estimated the likely medical effects of a scenario identified by leading experts as posing a serious danger: an accidental launch of nuclear weapons. We assessed possible measures to reduce the risk of such an event.

Results: U.S. and Russian nuclear-weapons systems remain on high alert. This fact, combined with the aging of Russian technical systems, has recently increased the risk of an accidental nuclear attack. As a conservative estimate, an accidental intermediate-sized launch of weapons from a single Russian submarine would result in the deaths of 6,838,000 persons from firestorms in eight U.S. cities. Millions of other people would probably be exposed to potentially lethal radiation from fallout. An agreement to remove all nuclear missiles from high-level alert status and eliminate the capability of a rapid launch would put an end to this threat.

Conclusions: The risk of an accidental nuclear attack has increased in recent years, threatening a public health disaster of unprecedented scale. Physicians and medical organizations should work actively to help build support for the policy changes that would prevent such a disaster.

In the 1990s, global concern over illicit trafficking in nuclear material to terrorists and nation-states has intensified. Two major changes are responsible: the evident new intent of terrorists to wound or kill thousands of civilians and the availability of inadequately protected "loose" nuclear materials in Russia and the newly independent former Soviet republics. These changes have made more likely attempts to acquire weapons-usable nuclear materials for terrorist use or for sale to state sponsors of terrorism. As a result, many efforts are being made to strengthen national and international standards for protection of nuclear material from theft and sabotage. One problem with current efforts is that national stnadards now vary widely. Although the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) mandates that non-nuclear weapon parties accept the safeguards requirements of the International Atomic Energy Agency (IAEA) for their nuclear activities, the relevant international standards for physical protection are mostly advisory.

Russia's current strategic nuclear force will become obsolete shortly after the turn of the century. Strategic modernization is therefore essential if Russia is to remain a nuclear power on a par with the US. But modernization will be extremely difficult because of the country's economic and political turmoil. Russia can probably maintain slightly more than 4,000 strategic nuclear warheads under the Strategic Arms Reduction Talks (START) I Treaty - roughly half of what the United States could, in theory, deploy. Under START II, Russia's strategic force will likely contain between 1,800 and 2,500 warheads, compared to 3,500 for the US. Hence, the easiest - perhaps the only - way for Russia to recover rough parity with the United States would be through a START III Treaty that limits both sides to 2,000-2,500 warheads.

From the preface:

"Events in recent years have caused heightened concern about the security of weapons-usable nuclear material. The possibility of illicit trafficking in, or seizure of, such material, leading to nuclear terrorism, is a worry for all states and their citizens. And given the relatively small quantities required, material obtained in one part of the world could be made into a weapon in another and threaten lives in a third. It is truly a global problem.

Since the beginning of the nuclear era, the physical protection of fissile material has been a responsibility of the individual states possessing the material. These states have different organizational approaches for providing physical protection; and while cognizant of recommended general standards, they tend to follow their own practices, shaped by custom, costs, and threat perception. Moreover, the existence of military as well as civil programs in some states adds another dimension
to the physical protection issue.

Because physical protection is a sovereign matter and not part of an international regime (except for transit of civil material across borders), there has been less attention in much of the world community to the issues of physical protection than to the other elements of nuclear safeguards and controls. (An important exception to this situation is the effort being made to assist the states of the former Soviet Union in the disposition of their weapons-usable nuclear materials.) The lack of a general dialog about a problem of growing concern motivated us to hold a three-day workshop at Stanford University to develop a better understanding of some of the important underlying questions and issues, and to undertake a comparative examination of states' approaches to physical protection. We were pleased to have knowledgeable participants from a number of the countries and regions where physical protection of fissile materials is, or will become, a day-to-day matter.

The results of the workshop are reported in these Proceedings. It is our hope that this work will stimulate further analysis and discussion, and lead to greater interest in international standards, cooperation, and supporting programs.

There is a growing logjam of arms control treaties waiting for approval in both the Russian State Duma and the U.S. Senate. Without decisive action, this logjam will probably prevent approval by the world's two largest military powers of the Strategic Arms Reduction Treaty (START II) of 1993, the Comprehensive Test Ban Treaty of 1996 (CTBT), amendments to the Anti-Ballistic Missile (ABM) Treaty, and the protocols of the Treaty of Pelindaba (creating an African nuclear-weapon-free zone (NWFZ)) and the Treaty of Rarotonga (creating a South Pacific NWFZ) before the end of the century. It will also prevent progress towards START III and further bilateral nuclear reductions.
