• Armored Transformer Barrier Protects Electric Power Grid

    A 2013 sniper attack on an electric power substation in Northern California, which caused more than $15 million in damages and destroyed 17 transformers, led researchers to develop a novel protective solution: the Armored Transformer Barrier system.

  • 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.”

  • Climate Change Contributor to 2017 Oroville Dam Spillway Incident

    A one-two punch of precipitation resulted in damage to Oroville Dam’s main and emergency spillways pushing the second largest dam in California into a crisis in February 2017. Researchers say that they have identified the fingerprint of climate change in the events that triggered the incident. Issues with the dam’s spillways led to the evacuation of 188,000 people.

  • 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.

  • Small-Scale Renewable Energy Sources Could Cause Power Failures

    Renewable energy that feeds into the main power grid could destabilize the system and potentially cause power failures according to a new study.

  • How Much Damage Could a Russian Cyberattack Do in the U.S.?

    U.S. intelligence analysts have determined that Moscow would consider a cyberattack against the U.S. as the Ukraine crisis grows. As a scholar of Russian cyber operations, I know the Kremlin has the capacity to damage critical U.S. infrastructure systems.

  • Wide Range of Possible Targets for Russian Cyberstrikes, from Infrastructure to Smartphones

    For years prior to Russia’s invasion of Ukraine, Vladimir Putin’s government waged cyberwar aimed at destabilizing the country’s infrastructure, government, and financial systems, including several distributed-denial-of-service (DDoS) attacks in the run-up to this week’s assault. What are Russia’s cyberwarfare capabilities, and what would a cyberattack against the U.S. look like?

  • 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.

  • If Russia Turns Off the Tap: LNG Could Boost European Energy Security

    Europe’s gas reserves are at their lowest in years with winter demand not yet over. As the Ukraine crisis escalates, raising fears over Russian supply, could liquefied natural gas (LNG) fill the gap?

  • The U.S. Digital Security Challenges: Q&A with Frederic Lemieux

    The U.S. is facing many digital challenges: Ransomware attacks; critical infrastructure vulnerability; exploitation of flaws in widely used software packages such as SolarWinds; potential Russian cyberattacks resulting from the Ukraine crisis; shortage of cybersecurity talent which leaves many government and private sector positions vacant; and many more. HSNW talked with Georgetown’s Professor Frederic Lemieux, a recognized expert in the fields of global threats and homeland security.

  • Can California’s Lithium Valley Power the EV Revolution?

    The Salton Sea geothermal field in California potentially holds enough lithium to meet all of America’s domestic battery needs, with even enough left over to export some of it. But how much of that lithium can be extracted in a sustainable and environmentally friendly way? And how long will the resource last?

  • 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.

  • Lake Evaporation Patterns Will Shift with Climate Change

    Lakes serve as a major global source of freshwater. As temperatures continue to get warmer, so will lakes. As global average temperatures rise, lake evaporation is projected to increase at double the rate of ocean evaporation. However, future increases in lake evaporation vary substantially across regions.

  • Prospect of War in Ukraine Raises Questions About Europe’s Natural Gas Supply

    The possibility of a Russian invasion of Ukraine is what an armed conflict in Eastern Europe raises the question of the repercussion to the energy supply of the countries of the European Union, which have become increasingly reliant on Russian natural gas for electricity generation, industrial applications, and commercial and residential use.
