Russia’s Remaining Weapons Are Horrific and Confounding

| Mar. 23, 2022

Along with concerns over the possible deployment of tactical nuclear weapons, the Biden administration is now warning that the Russian military may launch a chemical weapons attack in Ukraine. Russia has used chemical weapons during past conflicts, notably in Chechnya and Syria, in violation of international law. Russian officials denied Biden’s accusation during a U.N. Security Council meeting Tuesday.

The ecological tradeoffs of desalination in land-constrained countries seeking to mitigate climate change

| Feb. 18, 2022

The global demand for desalinated water is increasing at a remarkable rate. In a future with increasing demand for water and low-carbon electricity, an interesting ecological dilemma emerges. In a decarbonized world, providing desalinated water for domestic use and aquatic ecological restoration could increasingly come at the expense of open space lost to renewables such as solar photovoltaics (PV) and wind turbines. In this article we examine the environmental tradeoffs of providing freshwater from desalination under a solar photovoltaic-based decarbonization strategy, using Israel as an example.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The Overwhelming Case for No First Use

| Jan. 13, 2020

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

Uranium Supplies: A Hitch to China’s Nuclear Energy Plans? Or not?

| May 6, 2015

China will triple the number of nuclear power plants it has in operation by 2020 according to official plans, and the country’s nuclear fleet will increase 20-fold by 2050 under some not-yet-approved proposals. But how and where will China get the uranium to fuel them all? Will China need to resort to breeder reactors and reprocessing, with all the proliferation problems they incur? Or is there another way? In this journal article for the Bulletin of the Atomic Scientists, Hui Zhang suggests that between China’s domestic uranium mining, uranium purchased on the international market, and uranium mined by Chinese-owned companies overseas, China could meet even the most ambitious target, thus avoiding the troublesome and dangerous path of reprocessing.

Iran and Weapons of Mass Destruction: The Military Dynamics of Non-Proliferation

| 2014

Weapons of mass destruction (WMDs) are not suitable for the Iranian Army, given its non-mechanized nature; its defensive military posture; its current status as a non-nuclear weapon state; and its sufficient conventional preparation to meet its protective security interests. This paper proposes three interlinked policy approaches to resolve the current impasse.

Preventing Insider Theft: Lessons from the Casino and Pharmaceutical Industries

| June 17, 2013

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.

Expert Judgments about RD&D and the Future of Nuclear Energy

| 2012

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.

The Status of Advanced Small Pressurized Water Reactors

| Oct 1, 2012

In order to expand nuclear power energy in desalination and increase competitiveness in the global nuclear power market, many developed countries with strong nuclear technology have realized the importance of Small Modular Reactors (SMR) and initiated heavy research and development in SMR.The Advanced Small Pressurized Water Reactor (ASPWR) is characterized by great advantages, both in safety and economic mattters. It can be used in remote power grids and replace mid/small size fossil plants economically.This paper reviews the history and current status of SMR and ASPWR,and also discusses the design concepts, safety features and other advantages thereof.

The Balance of Power in the Persian Gulf: An Iranian View

| Fall 2010

"...[W]hile the traditional form of balance of power between Iran and Iraq provided security for the Arab states of the Persian Gulf, it favored the interests of foreign actors, especially the United States. Proponents of such a view hold that following the overthrow of the Baathist regime in Iraq and the growth of Iran's role and influence in the region, the international community ought to establish a new kind of balance of power to restrain the Islamic Republic of Iran, and thereby preserve the security of the region. Following its failure to redefine the position of the new Iraq in terms of a new balance of power, the United States has itself tried to play such a role in the region. U.S. efforts to minimize Iran's role within the context of the new balance of power have consequently created another security dilemma in the Persian Gulf."
