A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war.

Assessing Nuclear Security Risks in Pakistan

| June 2023

Pakistan’s nuclear program and perceived nuclear security concerns have attracted global attention. The varying concerns range from the potential theft of nuclear weapons or materials to the unauthorized use of a nuclear device to terrorist groups taking control of the Pakistani government. The enduring debate, however, has oscillated between these doomsday scenarios and some optimistic considerations, where various quarters have shared their satisfaction over Pakistan’s nuclear security regime and its ability to deal with the emerging challenges. To address the evolving nature of these threats, Pakistan is constantly improving its nuclear security infrastructure. It has established a comprehensive legislative and institutional structure, nuclear security systems, and has also undertaken various international obligations. To further improve nuclear security perceptions, Pakistan should adopt a more transparent approach and learn from international best practices.

Security Under Strain? Protecting Nuclear Materials During the Coronavirus Pandemic

| June 28, 2021

The coronavirus pandemic has had a significant impact on the nuclear industry, complicating operations and altering the delivery of both safety and security. This has generated concerns over the ability of governments and industry to provide vital services, while also protecting against changing threats that have evolved to take advantage of the pandemic. Christopher Hobbs, Nickolas Roth and Daniel Salisbury examine the nuclear security community’s response to this challenge, exploring how the risk landscape has been changed by the pandemic and the efficacy of new security solutions.

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:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 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.
