Global concerns over illicit trafficking in nuclear materials intensified in the 1990s. Some
countermeasures were taken, including steps involving the IAEA. But greater international cooperation, and higher standards of physical protection, may be needed to guard against the chance that weapons-grade material might fall into the wrong hands. This viewpoint article — based on a presentation to the IAEA’s International Conference on Physical
Protection in November 1997 — advocates steps to raise global standards, and to have them monitored internationally.

Risk can be thought of as the product of consequence times probability. No one can assign a number to the probability, for example, that a terrorist gang will acquire a nuclear weapon, although experts think the probability is considerably greater today than at any previous time. We do know, however, that the consequences of a nuclear explosion in any major population center would be catastrophic. The inescapable conclusion is that the global community is facing a very serious risk. What I want to discuss with you today is what is being done to deal with it and what still needs to be done.

Transcript of the first in a series of lectures on  "The U.S.-Russian Strategic Partnership: Premature or Overdue?"

This discussion focused on what Russia and the United States might do to dismantle the nuclear weapons legacy of the Cold War.  Tens of thousands of nuclear bombs and warheads are still held by the two nations.  Wat can be done to rid the world of these weapons?  Can we move beyond START II, and indeed, will the Russian Duma ratify START II? Russia and the United States have the capacity to lead the world into a post-nuclear war era.  The question for today is, will they?

This article analyses whether the Nuclear Non-Proliferation Treaty (NPT) provides legal authority for International Atomic Energy Agency (IAEA) efforts to gain more information and more intrusive inspections to assure that non-nuclear-weapons States (NNWS) have joined the NPT are not attempting to make nuclear weapons in violation of that Treaty.

This report summarizes analytical work completed on the Trident SLBM nuclear weapons safety issue. First, we evaluated the increase in low levels of risk of death from cancer from potential plutonium dispersal accidents at the Trident base at Kings Bay, Georgia. Specifically, we estimated the number of latent cancer fatalities resulting from a hypothetical worst-case accident involving a 10-kilogram release of weapons-grade plutonium aerosol at Kings Bay with the wind direction toward downtown Jacksonville, located 55 kilometers away. The estimated number of long-term cancer deaths ranges from 5 to 3300 and depends on a number of factors and assumptions including deposition velocity, wind speed and direction, the nature of the plume, and mixing layer height.

Second, we applied a simple, "back ofthe envelope" risk-analytic approach to the Trident safety problem to try to shed some light on the key question: How much should be spent on safety modifications for Trident? Depending on a variety of assumptions and value judgments, our analysis suggests that if one believes that the probability of a serious accident over the 30-year Trident program lifetime is of order 0.01 to 0.10, then an expenditure of $1-5 billion to increase safety is not unwarranted given reasonable estimates of the consequences of such an accident.

The end of the Cold War creates both new challenges and new opportunities for improving nuclear weapons safety. Several post Cold War developments are likely to have negative effects on the safety of existing nuclear weapons arsenals. These potentially dangerous trends include an apparent decline of morale in the laboratories and military organizations responsible for weapons safety, the potential proliferation of nuclear weapons to new states, the likely discontinuation of nuclear testing for safety related purposes, and the introduction of new nuclear weapons operations, including large-scale warhead dismantlement and the relocation and long-term storage of large numbers of nuclear weapons.

In an effort to explore such challenges and opportunities, a NATO Advanced Research Workshop was held in Oxford, England from August 25^th through 27^th, 1994. The workshop produced seven specific proposals for consideration to increase nuclear weapons safety and security. The proposals represent a summary of the points discussed at the workshop and are not intended to imply complete consensus of all participants.
