• Today, Everyone’s a Nuclear Spy

    There was a time when tracking nuclear threats was the domain of secret agents, specialists at high-powered government intelligence agencies, and think-tank experts. Not anymore. Amy Zegart writes that today, the world of new nuclear sleuths looks like the Star Wars bar scene. What has empowered these nuclear detectives and made their work possible is the fact that in the last 15-20 years, commercial satellites have become common – and their capabilities, although not at the level of spy satellites, are not too far behind. Open-source amateur nuclear sleuthing comes with risks, but Zegart says that despite these risks, the democratization of nuclear-threat intelligence is likely to be a boon to the cause of nonproliferation.

  • Worry: Iran Said It Will Continue to Enrich Uranium Beyond Radioactive Isotopes Level

    Tehran sent a letter to the UN Thursday saying that it was “determined to resolutely continue” enriching uranium. This came following an EU letter criticizing the Iranian government’s decision, and a Russian firm suspending cooperation in Iran’s uranium enrichment program at the underground Fordo facility.

  • Britain’s Secret War with Russia

    A drab office building on the outskirts of the Swiss town of Spiez houses Switzerland’s Federal Office for Civil Protection, renowned for its work on global nuclear, chemical, and biological threats.Over the course of a few months in 2018, this outfit’s gentle existence was upended, as the lab became caught in a cold war between Russia on one side and the United Kingdom and the West on the other.

  • DHS S&T Event to Host Innovators, Researchers, Experts on Canine Detection

    Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is inviting innovators, researchers, and canine training experts to learn about funding opportunities in the detection canine field. “We want to reach a broad spectrum of innovators to help us solve our most important detection canine research challenges,” said Don Roberts, S&T’s Detection Canine Program Manager.

  • Underwater Telecom Cables to Be Used as Seismic Detection Network

    About 70 percent of Earth’s surface lies under the sea, which means that, until now, most of the Earth’s surface had been largely without early-warning seismic detection stations. Scientists say that fiber-optic cables that constitute a global undersea telecommunications network could one day help in studying offshore earthquakes.

  • Newly Proposed Barrier Could Have Limited Radiation Release at Chernobyl, Fukushima

    Following the most serious nuclear accidents in the history — at Three Mile Island (1979), Chernobyl (1986) and Fukushima (2011), in which release of radiation occurred as a result of core meltdown — many countries around the world have committed to phase out nuclear power. Afuture powered by nuclear energy, however, may be neither a lost cause nor a game of “Russian roulette,” according to researchers.

  • The U.S. Wants to Bury SC’s Plutonium Stockpile Forever. Its New Home Isn’t Sure It Wants It.

    How long will it take for weapons-grade plutonium stockpile, temporarily stored at the South Carolina’s Savanah River nuclear weapons complex, to decay, that it, to have its radioactivity reduced to a level at which it will no longer pose radiation risks or turned into nuclear weapons? About seven billion years, or a little more than double the age of planet Earth. The government’s plutonium plan calls for expanding a nuclear waste burial ground located inside an abandoned salt mine near Carlsbad, New Mexico, which is known as the Waste Isolation Pilot Plant, or WIPP. But New Mexico objects.

  • Dealing with the Soviet Nuclear Legacy

    On 29 August 1949, the Soviet Union conducted their first nuclear test. Over a 40-year period, they conducted 456 nuclear explosions at Semipalatinsk, in eastern Kazakhstan — 116 aboveground and 340 underground. After the collapse of the Soviet Union in 1991, many of the scientists and military personnel abandoned the site and fled the country, leaving behind large quantities of nuclear materials, completely unsecured. The Defense Threat Reduction Agency (DTRA) has been quietly helping Kazakhstan deal with the Soviet nuclear legacy.

  • Iran’s Nuclear Weapons “Breakout” Time Getting Shorter: Experts

    The Trump administration’s withdrawal from the 2015 nuclear agreement with Iran, and the administration’s “maximum pressure” policy, are failing to yield the desired results, as Iran, pursuing a methodical “creep-out” strategy, is reconstituting its nuclear weapons program. In 2015, Iran’s “breakout” time, that is, the amount of time Iran would need to produce enough weapon-grade uranium for a nuclear weapon, was three months. The 2015 agreement, by imposing serve technical restrictions and intrusive monitoring, increased Iran’s breakout time to about twelve months. Experts now say that since the U.S. withdrawal from the treaty, Iran’s breakout time has been reduced to 6-10 months. “The breakout time will decrease further as Iran increases its stock of enriched uranium and installs more centrifuges,” the experts say.

  • Operations in French Nuclear Power Plant Suspended after Monday Tremor

    Following a strong earthquake Monday in the Drôme and Ardèche regions in south-east France, EDF (Électricité de France) has ordered the suspension of power production at the Cruas-Meysse power station. The magnitude 5.4 earthquake shook the area at 11:52 a.m. Monday. Of France’s nineteen active nuclear power plants, five plants are located in seismically active zones.

  • New Reactor Designs Will Degrade Waste More Rapidly

    Renewed interest in nuclear power as a viable option for generating electricity has been accompanied by steady progress in reactor design. Advanced reactors offer the promise of greater fuel efficiency and less radioactive waste generation compared with the water-cooled models that have dominated the nuclear power landscape for decades. Newer designs, however, will operate at higher temperatures and use highly corrosive coolants — like liquid metal, molten salt, or high-temperature gas — all of which would rapidly degrade many of the materials used in conventional nuclear reactors.

  • Preparing for Chemical Attacks

    Is the U.S. ready for a chemical attack on the homeland? With the very real possibility of a chemical attack in public spaces like stadiums, religious buildings, museums and theaters, or even contamination of the food or water supply, the U.S. needs to be prepared to take appropriate action to save lives. This means having security measures in place to prevent or minimize the attack. It also means having effective medical responses that consider the quantity of medical supplies needed, transportation of those supplies to the scene, and medical facilities and personnel to care for the injured.

  • Converting Big Data into Real-Time, Actionable Intelligence

    Social media, cameras, sensors and more generate huge amounts of data that can overwhelm analysts sifting through it all for meaningful, actionable information to provide decision-makers such as political leaders and field commanders responding to security threats. Researchers are working to lessen that burden by developing the science to gather insights from data in nearly real time.

  • Can American Values Survive in a Chinese World?

    The People’s Republic of China bounds from strength to strength. Every year sees increases in its wealth and power relative to the world. But what do its leaders hope to achieve with their newfound clout? Jonathan D. T. Ward’s book China’s Vision of Victory traces the Chinese desire to shape the future of all mankind (not just the East Asian part of it) to a national myth taught to schoolchildren across China. According to this narrative, China was once the center of the world; China was the mother of invention, the seat of global wealth, and the beacon of civilization. This is China’s natural role in the world order—a role disrupted by the “century of humiliation” between the Opium Wars and World War II, when China suffered at the hands of foreign powers. But now that age of suffering is over. China’s destiny, according to its leaders, is to reclaim its natural perch as the leading force of human civilization. Tanner Greer writes that these global ambitions raises serious questions for the United States – questions which go beyond whether Americans will be willing to live in a world where China is the supreme economic and military power. The “hardest question may be whether we are willing to live in a world where dominant economic and military power is wielded by an insecure regime whose leaders believe that the same authoritarian techniques used to control enemies within their society must be used to surveil, coerce, and corrupt those enemies outside it.”

  • Helping First Responders Identify Unknown Chemicals

    First responders arrive first on the scene when disaster strikes or terrorists attack. They often encounter dangerous conditions like smoke and chemicals. To best help in situations like these, they need to know the chemical substances present onsite. This is where analytical field instruments such as Gas Chromatograph/Mass Spectrometers (GC/MS) come into play. But to acquire such technology, first responders first need to know which GC/MSs suit both their needs and their budgets.
