• 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.

  • India-Pakistan Nuclear War Could Kill Millions, Lead to Global Starvation

    A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people—more than the death toll during all six years of World War II, according to new research. The researchers calculated that an India-Pakistan war could inject as much as 80 billion pounds of thick, black smoke into Earth’s atmosphere. That smoke would block sunlight from reaching the ground, driving temperatures around the world down by an average of between 3.5-9 degrees Fahrenheit for several years. Worldwide food shortages would likely come soon after. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.

  • North American Seismic Networks Can Contribute to Nuclear Security

    The International Monitoring System is the top global seismic network for monitoring nuclear weapon tests around the world. To expand the system’s detection capabilities, however, international monitors should seek out the data, methods and expertise of smaller regional seismic networks.

  • How to Dismantle a Nuclear Bomb: Team Successfully Tests New Method for Verification of Weapons Reduction

    How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets. Now MIT researchers have successfully tested a new high-tech method that could help inspectors verify the destruction of nuclear weapons. The method uses neutron beams to establish certain facts about the warheads in question — and, crucially, uses an isotopic filter that physically encrypts the information in the measured data.

  • Containing a Nuclear Accident with Ground-up Minerals

    Researchers at Sandia National Laboratories are developing a promising new way to prevent the spread of radioactive contamination and contain the hot molten mass that develops within a nuclear reactor during a catastrophic accident. A team of scientists discovered and patented a process for injecting sand-like minerals into the core of a nuclear reactor during an accident to contain and slow down the progression of a meltdown.

  • A Meltdown in Nuclear Security

    A commando raid on a nuclear power plant seems the stuff of Hollywood. So why are nuclear security experts so worried? It ranks among the worst-case scenarios for a nuclear power plant: an all-out assault or stealth infiltration by well-trained, heavily armed attackers bent on triggering a nuclear blast, sparking a nuclear meltdown or stealing radioactive material. Under pressure from a cash-strapped nuclear energy industry increasingly eager to slash costs, the commission in a little-noticed vote in October 2018 halved the number of force-on-force exercises conducted at each plant every cycle. Four months later, it announced it would overhaul how the exercises are evaluated to ensure that no plant would ever receive more than the mildest rebuke from regulators – even when the commandos set off a simulated nuclear disaster that, if real, would render vast swaths of the U.S. uninhabitable. Nuclear security experts, consultants, law enforcement veterans and former NRC commissioners are nothing short of alarmed. “You can’t afford to be wrong once,” says one expert.

  • Sniffing Out Signs of Trouble

    A NIST researcher is conducting the first field test of a high-tech sniffing device called a PLOT-cryo — short for “porous layer open tubular cryogenic adsorption.” This NIST-invented device can be used to detect very low concentrations of chemicals in the air. The technology offers a new way to screen shipping containers at ports of entry.
