• 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.

  • Ensuring Safe Nuclear Waste Disposal

    Disposal concepts call for the waste to be isolated a third of a mile belowground for safe storage, enclosed within engineered barrier systems and surrounded by subsurface rock. But there’s still the chance radionuclides might leak out if these systems lose their protective properties as it heats up due to radioactive decay. International nuclear waste disposal research effort evaluates maximum allowable temperature for buffer material.

  • Radioactive Contamination Is Creeping into Drinking Water Around the U.S.

    As mining, fracking and other activities increase the levels of harmful isotopes in water supplies, health advocates call for tighter controls.

  • Belgium to Shut Down All Existing Nuclear Power Plants

    The Belgian government has said all of the country’s existing nuclear energy plants will close by 2025. However, Belgium will invest in future nuclear technology.

  • Iran Can Produce One Nuclear Weapon in as Little as Three Weeks

    The growth of Iran’s stocks of near 20 and 60 percent enriched uranium has dangerously reduced breakout timelines: Iran has enough enriched uranium hexafluoride (UF6) in the form of near 20 and 60 percent enriched uranium to produce enough weapon-grade uranium (WGU), taken here as 25 kilograms (kg), for a single nuclear weapon in as little as three weeks. It could do so without using any of its stock of uranium enriched up to 5 percent as feedstock.

  • New Treatment Technology Could Reduce Nuclear Waste Burden

    Researchers have developed a novel treatment technology that may help to significantly reduce the burden of nuclear waste. This breakthrough could therefore significantly speed up disposal of such material and reduce the overall cost of dealing with our legacy waste.

  • Redesigning Radiation Monitors at U.S. Ports of Entry

    Every day at ports of entry around the country, hundreds of thousands of vehicles and containers cross into the country. Since 9/11, all incoming vehicles and containers at land crossings, rail crossings, mail facilities, and shipping terminals are scanned by Customs and Border Protection (CBP) officers to detect potential threats, including radiation. The time has come to replace and upgrade the aging radiation detection systems.

  • Future Solutions for Spent Nuclear Fuel

    Nuclear technology has been used in the United States for decades for national defense, research and development, and carbon-free electric power generation. Nuclear power is a key element of the U.S. response to climate change and reducing greenhouse gas emissions. However, nuclear energy, as an essential form of electricity production, generates radioactive waste in the form of spent nuclear fuel. Spent nuclear fuel must be handled, stored, and ultimately disposed of in a manner that won’t harm the environment.

  • RadSecure 100 Radiological Security Initiative Launched in 100 U.S. Cities

    The RadSecure 100 Initiative focuses on removing radioactive material from facilities where feasible and improving security at the remaining facilities located in 100 metropolitan areas throughout the United States. Partnerships with local medical facilities, industrial firms, and law enforcement will be key to the project.

  • Extending Nuclear Power Accident Code for Advanced Reactor Designs

    Nuclear power is a significant source of steady carbon-neutral electricity, making the design and construction of new and next-generation nuclear reactors critical for achieving the U.S.’s green energy goals. A number of new nuclear reactor designs, such as small modular reactors and non-light water reactors, have been developed over the past 10 to 15 years.Sandia Lab researchers have been expanding their severe accident modeling computer code, called Melcor, to work with different reactor geometries, fuel types and coolant systems.
