• To Check Iran’s Missiles, JCPOA Re-Entry is a Must

    Iran’s missile program is a cause for international concern. John Krzyzaniak and Akshai Vikram write that Iran’s increasing willingness and ability to launch missiles at neighboring countries merits a coordinated, international response. If Iran were to ever acquire a nuclear weapon, its unchecked missile program could allow it to hold entire cities at risk in the Middle East and potentially beyond. “If the United States is ever going to restrict Iran’s missile program through diplomacy, re-entering the 2015 Iran nuclear deal is the best – and likely only – way to make it happen,” they write.

  • Comparing Geologic Repository Assessment Tools

    A computer modeling system is designed to answer critical safety assessment questions about future disposal options for spent nuclear fuel deep underground and the system of tunnels, containers and possible concrete-like barriers used to keep the radioactive material contained far from the surface and water sources.

  • Risks of an Unfamiliar New Nuclear Age

    High-tech advances in weapons technologies and a return of ‘great power nuclear politics’, risk the world ‘sleepwalking’ into a nuclear age vastly different from the established order of the Cold War, experts warn. Stockpiles are much reduced from the peak of up to 70,000 nuclear weapons seen in the 1980s, but progress in a number of new or ‘disruptive’ technologies threatens to fundamentally change the central pillars on which nuclear order, stability and risk reduction are based.

  • New Treatment Removes Radioactive Barium from Nuclear Wastewater

    Exposure to ionizing radiation can be extremely dangerous for humans and animals. High acute doses lead to radiation burns and radiation sickness that can be lethal. Researchers havedeveloped a new process that offers a rapid and effective path to remove some of the most harmful of these ions – barium.

  • Risks of a Dirty Bomb Attack Are Increasing

    In a new factsheet, the GAO says that the risks of a dirty bomb attack are increasing and the consequences could be devastating.

  • Iran Vows to Continue Nuclear Activities

    Iranian President Ebrahim Raisi has said Iran will continue nuclear development activities as talks to revive Tehran’s nuclear deal with world powers remain stalled. The nuclear deal collapsed four years ago when former President Donald Trump withdrew the United States from the agreement, allowing Iran to vastly expanded its nuclear work.

  • Food Security During a Nuclear Winter

    A nuclear war would cause global blockage of the sun for several years due to injections of black carbon soot into the upper atmosphere, covering most of the planet with black clouds. This could result in less than 40 percent of normal light levels near the equator and less than 5 percent normal light levels near the poles. Research focuses on how meeting food security and nutrition in post-catastrophe conditions, which could last 15 years in some wet tropical forests.

  • Can Ukraine Be Saved Without Triggering a Nuclear Response?

    Worries about the war in Ukraine are deepened by the prospect that if, against the odds, Russian forces are brought to the point of defeat, Putin will launch a ‘battlefield’ or ‘tactical’ nuclear weapon to destroy the forces opposing the Russian military, and, perhaps, even attack military bases inside neighboring countries – some are NATO member states – which provide supplies to the resistance.

  • What Are the Risks at the Chernobyl Nuclear Plant?

    Threat of a nuclear catastrophe is low. But experts fear for safety of workers who have been unable to rotate off shift. Communications with the site are down and electricity has reportedly been lost.

  • Russian Attack on, Takeover of Ukraine Plant Ramps Up Nuclear Threat

    Russia’s attack last Friday on a nuclear power plant in southeastern Ukraine has heightened concerns of a nuclear catastrophe in the region, and not only as a result of unintended leaks or possible future attacks on Ukraine’s three remaining nuclear plants. Statements by Russian President Vladimir Putin and Foreign Minister Sergey Lavrov have further deepened worries that Russia may seek to turn material in captured reactors into “dirty bombs.”

  • The Dangers Following Russia’s Attack on the Zaporizhzhia Nuclear Power Plant

    Following recent news of Russian shelling of Zaporizhzhia nuclear power plant in southern Ukraine, which is the largest in Europe, there is great concern over the potential for a Chernobyl-esque release of radioactive material. Several security personnel at the plant were injured by the attack.

  • Exploring the Impact of the COVID-19 Pandemic on Nuclear Security

    A new study examines measures put in place in the nuclear sector in the U.K. to mitigate risks from the pandemic. The study identifies a series of lessons learnt in maintaining nuclear security. It also provides recommendations for managing the continuing impact of the pandemic and preparing for future crises.

  • Improved Nuclear Accident Code Helps Policymakers Assess Risks from Small Reactors

    New software will help the global nuclear industry in assessing the consequences of nuclear accidents. The Maccs code, developed by Sandia researchers, can also evaluate the potential health and environmental risks posed by advanced nuclear reactors and small modular nuclear reactors.

  • Providing Student Research Opportunities to Strengthen Nuclear Security

    Student researchers at The University of Texas at El Paso Aerospace Center will engage in nuclear materials technology research through a five-year, $5 million grant from the U.S. Department of Energy (DOE). Work will focus on the design, synthesis and fabrication of advanced materials.

  • The Resilience and Safety of Nuclear Power in the Face of Extreme Events

    As the prospect of extreme global events grows — from natural disasters and intensifying climate change-driven weather patterns that could affect a nuclear plant, to a rise in infectious diseases that could affect its workforce — nuclear power plants’ adaptable workforces and robust designs will be essential to staying resilient and contributing to a low carbon path to the future.
