After worldwide calls to action in the wake of the tsunami that devastated Fukushima Daiichi in March 2011, nuclear power plants have been shoring up their defenses for more than a year. Much has already been accomplished; many projects are only months away from realization. The end of 2013 marks the deadline for many countries’ medium-term actions. This article provides a country-by-country report which aims to give an overview of actions taken in most countries operating nuclear power plants.

"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."

A multinational solution for keeping states out of the nuclear weapons business.

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.

Nuclear weapons have the capability to destroy all the creatures of this Earth. As long as nuclear weapons exist, there is a danger of accidental or deliberate use with disastrous consequences. Therefore, the negotiation of a NWC is vital to all humanity. However, such negotiations have not started yet because of the opposition of the nuclear weapon states (except China). The NWC negotiations will not make progress without these states’ participation. The main reason for these nuclear states’ objections to NWC negotiations is that they continue to rely on the deterrence role of nuclear weapons, despite there being no rationale for deterrence since the end of the Cold War. To reach the goal of the NWC, therefore, the major steps are to reduce the deterrence role of nuclear weapons and to render such weapons unusable.

Carter, Deutch, and Zelikow addresses the threat of Catastrophic Terrorism in Foreign Affairs.

A water vapour plume from a cooling tower vent at Khushab and the discharge of hot water at Trombay prove that Pakistan and India are producing plutonium for nuclear weapons. Easily available satellite images should be used to make them stop proliferation in South Asia.

A new international regime could stop nations before they enter the proliferation “red zone.”
