Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

A Process for Capturing CO2 from the Atmosphere

    Authors:

| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.

Nuclear Security in Russia: Can Progress Be Sustained?

| May 08, 2018

Nuclear security in Russia has continued to evolve since the suspension of nearly all US–Russian nuclear-security cooperation in 2014, but the United States and the rest of the world now know much less about the directions of this evolution. This article assesses the current state of nuclear security in Russia based on an examination of key drivers of Russia’s nuclear-security system, from allocation of resources to regulatory oversight. It then outlines four scenarios for the future of evolution of nuclear security in Russia, describing potential causes, implications, and observable indicators for each scenario. It closes with recommendations designed to maximize the chance of moving onto a path of continuous improvement of nuclear security.

Is Nuclear War Inevitable?

| Dec. 28, 2017

Donald Trump and Kim Jong-un trading threats with words like “fire and fury”; Pakistan deploying tactical nuclear weapons to counter Indian conventional threats; Russia enunciating an Orwellian doctrine of “escalate-to-de-escalate” that calls for early use of battlefield nuclear weapons; and major nuclear-weapons states modernizing their arsenals — nukes are back. The cruel irony: This is happening after eight years of a president who won the Nobel Peace Prize largely for his vision of a world free of nuclear weapons.

Tomcat and Mouse: Iranian Illicit Procurement of U.S. Legacy Military Technologies, 1979–2016

| Autumn 2017

Since the 1979 revolution, Iran has sought to illicitly procure parts for the U.S. origin fighter aircraft sold to the country under the rule of the Shah. The U.S. has taken steps to quash this trade—these efforts have constituted a relatively large proportion of U.S. export control enforcement over the past near-to-four decades.

Nuclear Energy in the Middle East? Regional Security Cooperation Needed

| Spring 2017

Nuclear power in the Middle East has appeared poised for dramatic growth for more than a decade.  Iran’s nuclear power plant at Bushehr, the first of its kind in the Middle East, began producing electricity in 2011. Tehran has plans or proposals for additional 11 reactors, according to the World Nuclear Association. Saudi Arabia has announced plans to build 16 nuclear power reactors by 2040. The UAE has four nuclear power reactors under construction, the first of which is expected to come online later this year.  Egypt, Turkey, and Jordan, are each pursuing the development nuclear energy at their own pace.  The appearance of activity is impressive.

Evolving State and Nonstate Proliferation Threats

| Winter 2016

UN Security Council resolution 1540 has come a long way since it was approved over a decade ago. Initially, many countries questioned the legitimacy of the Security Council “legislating” requirements for countries all over the world, and there were wide gaps in both reporting and action. Today, UNSCR 1540 is a broadly accepted part of the international landscape, only a few countries have not yet provided at least basic reporting on steps taken under the resolution, and many countries have taken action to fulfill the resolution’s requirements, ranging from enacting export control laws to strengthening security for biological pathogens.

Improving Nuclear Safety, Security, and Nonproliferation in Northeast Asia through Multinational Approach

| December 31, 2016

Reviewing recent developments in nuclear energy, it is clear that Northeast Asian countries have become the leading customers and suppliers of nuclear technology worldwide. However, regional cooperation in the nuclear field remains inadequate when compared to the close economic interaction between these states and their need for solutions to pressing issues, such as supply assurance and spent fuel management. At the same time, with events like the Fukushima accident or the ongoing nuclear crisis in North Korea, there is an urgent demand for Northeast Asia to improve the safety, security, and nonproliferation status of the regional nuclear programs as any nuclear-related incident in any regional state will have transnational impact on the economic and social stability of the whole region.

Strengthening Nuclear Security in a Post-Summit World

| Summer 2016

This spring, the United States hosted the fourth and final Nuclear Security Summit in Washington, DC. Senior representatives of more than 50 nations convened to mark the end of an unprecedented international initiative over the last six years to strengthen security measures aimed at preventing nuclear terrorism. During that time, many states made significant progress, but more work is needed.
