Successful environmental management is partly contingent on the effective recognition and communication of environmental health risks to the public. Yet risk perceptions are known to differ between experts and laypeople; laypeople often exhibit higher perceptions of risk in comparison to experts, particularly when these risks are associated with radiation, nuclear power, or nuclear waste. This paper consequently explores stakeholder risk perceptions associated with a mercury-contaminated chloralkali production facility in Kazakhstan.

"If nuclear power is to grow on the scale required to be a significant part of the solution to global climate disruption or scarcity of fossil fuels, major steps are needed to rebuild confidence that nuclear facilities will be safe from accidents and secure against attacks."

During the Cold War, the threat of a nuclear attack came mainly from the U.S.-Russian nuclear arsenals, writes Kevin Ryan. Today, however, the United States and Russia have been forced to adapt to a new nuclear threat—that of dedicated terrorists with money and technological access who seek to obtain and use a nuclear device.

In 1985, researchers at the Harvard Kennedy School published a book called “Hawks, Doves, and Owls,” and gave it an ambitious subtitle: “An Agenda for Avoiding Nuclear War.” Those scholars gathered again at the School on Monday (May 16) for a seminar on the current challenges in avoiding nuclear war — and to marvel at just how drastically the nuclear threat has morphed in the two decades since the Cold War ended and the Soviet Union collapsed.

"Our crystal ball is not clear enough to predict with confidence whether the global nuclear future will be characterized by peace and prosperity or by conflict and destruction. But we do believe that the choices made in the coming few years will be crucial in determining whether the world can have more nuclear power without more nuclear weapons dangers in the future."

"Keeping nuclear weapons and the difficult-to-manufacture materials needed to make them out of terrorist hands is critical to U.S. and world security — and to the future of nuclear energy as well. In the aftermath of a terrorist nuclear attack, there would be no chance of convincing governments, utilities, and publics to build nuclear reactors on the scale required for nuclear energy to make any significant contribution to coping with climate change."

"...[A] primary goal in the next decades must be to remove this risk of near global self-destruction by drastically reducing nuclear forces to a level where this outcome is not possible, but where a deterrent value is preserved — in other words, to a level of minimum deterrence. This conception was widely discussed in the early years of the nuclear era, but it drowned in the Cold War flood of weaponry. No matter how remote the risk of civilization collapse may seem now — despite its being so vivid only a few decades ago — the elimination of this risk, for this century and centuries to come, must be a primary driver for radical reductions in nuclear weapons."

Will the growth of nuclear power lead to increased risks of nuclear weapons proliferation and nuclear terrorism? Will the nonproliferation regime be adequate to ensure safety and security in a world more widely and heavily invested in nuclear power? The authors in this two-volume (Fall 2009 and Winter 2010) special issue of Dædalus have one simple and clear answer to these questions: It depends.

Hui Zhang argues that an effective universal Fissile Material Cutoff Treaty (FMCT) would make an important contribution to nuclear disarmament, the nonproliferation regime, and the prevention of nuclear terrorism. However, such a FMCT must have a credible verification regime. Dr. Zhang suggests that it should be technically feasible to establish an effectively verifiable FMCT at a reasonable cost, while protecting national security secrets.
