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.

Probabilistic estimates of the cost and performance of future nuclear energy systems under different scenarios of government research, development, and demonstration (RD&D) spending were obtained from 30 U.S. and 30 European nuclear technology experts. The majority expected that such RD&D would have only a modest effect on cost, but would improve performance in other areas, such as safety, waste management, and uranium resource utilization. The U.S. and E.U. experts were in relative agreement regarding how government RD&D funds should be allocated, placing particular focus on very high temperature reactors, sodium-cooled fast reactors, fuels and materials, and fuel cycle technologies.

This paper aims to provide a comprehensive assessment of the Chinese nuclear energy program and policy, reviewing its past, present, likely future developments, as well as to consider potential challenges that deserve further attention. This paper will explore reasons that have caused the existing industry, describe China's nuclear bureaucracy and decision making process to understand how different stakeholders play a role in China's nuclear energy development. This study concludes that China's existing nuclear program and industry, in combination with its current stable economic and political environment, provides a sound foundation for the planned nuclear expansion. However, challenges which are crucial to the success of the nuclear expansion will need to be addressed.

"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."

"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."

"...[T]here are plenty of laws that require or authorize sanctions against governments that knowingly provide direct support to proliferators. But these laws offer little protection against those governments that—through neglect, corruption, or incompetence—fail to keep the materials and technology needed to make nuclear, biological, and chemical weapons from slipping out of their control and across their borders."

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.
