Through structured interviews and a literature review, we assess which approaches to protection against insider thefts in the casino and pharmaceutical industries could be usefully applied to strengthen protections against insider theft in the nuclear industry, where insider thefts could have very high consequences.

This article examines and evaluates security measures at Chinese civilian nuclear power plants and suggests ways to improve them. It also reviews current export control policies and systems, identifies likely challenges to the expanding nuclear sector, and proposes possible solutions.

"An ambitious reinvigoration of the grand bargain that was struck 40 years ago in the NPT is needed to usher in a new era of cooperation on preventing proliferation. The renewed grand bargain will need to combine steps that can be taken immediately alongside a vision for the longer term. It will also need to draw in states that are not parties to the NPT. Rather than rushing toward confrontation, with all its risks, all sides must put historic antipathies aside and find face-saving solutions. To give the Iranian advocates of compromise a chance to succeed, the United States and the other major powers need to put offers on the table that will show the people of Iran that nuclear restraint and compliance will put their nation on a path toward peace and prosperity."

"Without energy, there is no economy. Without climate, there is no environment. Without economy and environment, there is no material well-being, no civil society, no personal or national security. The overriding problem associated with these realities, of course, is that the world has long been getting most of the energy its economies need from fossil fuels whose emissions are imperiling the climate that its environment needs."

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."

Nuclear terrorism is a realistic threat to all countries. First, this article describes the potential threats of nuclear terrorism including nuclear explosives, nuclear sabotage, and dirty bombs. Finally, this article recommends steps to secure nuclear weapons, nuclear materials, and nuclear facilities.

Pakistan's security environment has deteriorated through its adoption of a declared nuclear weapons posture in May 1998. Internal fissures have widened along regional and sectarian lines as the Pakistani economy falters, unable to sustain even limited external sanctions following decades of internal mismanagement. Tensions with India have also increased as Pakistan's security managers adopt interventionist policies, based on a misplaced belief in the deterrent value of nuclear weapons. The international community, in particular, the USA's failure to reverse South Asian nuclear proliferation, has emboldened Indian advocates of nuclear deployment. If India deploys nuclear weapons and their delivery systems, Pakistan will follow suit. Operation-ready nuclear weapons will increase the prospects of an India - Pakistan conflict that could assume a nuclear dimension. Pakistan's nuclear weapons capability will not prevent an Indian conventional attack nor will the presence of nuclear weapons deter an Indian accidental, unauthorised or preventive nuclear attack. Changed domestic and external priorities alone can buttress Pakistani security.

The operation of dedicated plutonium-production reactors and large gaseous-diffusion uranium-enrichment plants (GDPs), can be detected remotely using commercial observation-satellite imagery. Declassified Corona imagery is used to demonstrate that the new generation of commercial observation satellites with 1-meter spatial resolution will be able to detect vapor plumes inside and downwind from large operating natural-draft cooling towers. Low-resolution Landsat-5 thermal infrared images have been shown by other authors to be able to detect warm water discharges from reactors into lakes, rivers, etc. Here, the same systems are shown to be able detect the elevated temperature of the roofs of large operating GDPs. Commercial-satellite observations could therefore play an important role in increasing confidence in declarations that plutonium-production reactors and GDPs have been shut down as a result of a fissile material-production moratorium or Fissile Material Cutoff Treaty.

One key building block in a comprehensive strategy to contain and eliminate nuclear weapons is the Fissile Material Cutoff Treaty (FMCT), which would ban the production of plutonium and highly enriched uranium (HEU) for nuclear weapons. However, negotiations on this treaty have been at an impasse in Geneva since 1993. Since realistically a FMCT will probably not come into force for some years, a moratorium on the production of fissile material for weapons should be encouraged in order to capture as many of the benefits of an FMCT in the interim.

Negotiations on a fissile material cut-off treaty (FMCT) may soon be launched at the Conference on Disarmament in Geneva after several years' delay caused by debates over its scope and linkage to nuclear disarmament measures. Fissile material, in practice plutonium or HEU, is the fundamental ingredient in all nuclear weapons. It is also the most difficult and expensive part to produce. A global, verified ban on the production of fissile materials for nuclear explosives would be a key building block in a comprehensive strategy to contain and eliminate nuclear weapons.
