• New cracks found in aging Belgian nuclear power plant

    More micro-cracks have been discovered at the Belgian Tihange 2 nuclear reactor near the German border. safe. The worries in Germany about radiation leaks from the old reactor are strong. Last year, the government of the German state of North Rhine-Westphalia, which is on the other side of the Belgian-German border, purchased iodine tablets for distribution to the public in the event of radiation leak. Belgium relies on its two 40-year old nuclear reactors for 39 percent of its energy needs, and has extended the operational life of both, even though they were supposed to be decommissioned a decade ago.

  • Remote detection of hazardous radioactive substances

    Remote detection of radioactive materials is impossible when the measurement location is far from its source. A typical radiation detectors, like Geiger-Muller counters can detect 1 milli Curie (mCi) of Cobalt-60 (60Co) at a maximum distance of 3.5 meters, but are inefficient at measuring lower levels of radioactivity or at longer distances. Researchers have developed a method for the remote detection of hazardous radioactive substances. With the help of this newly developed detection device, the detection of various types of radioactive materials can be done from a remote distance.

  • Detecting and preventing the use of chemical weapons

    Like detectives looking for clues, researchers at the Department of Energy’s Pacific Northwest National Laboratory have been working for nearly a decade on ways to identify the “fingerprints” of potential chemical threats. The ability to identify a particular agent and attribute its source is key to responding to and even preventing these threats.

  • New fabric coating could neutralize chemical weapons, save lives

    Chemical weapons are nightmarish. In a millisecond, they can kill hundreds, if not thousands. But, in a new study, scientists report that they have developed a way to adhere a lightweight coating onto fabrics that is capable of neutralizing a subclass of these toxins — those that are delivered through the skin. The life-saving technique could eventually be used to protect soldiers and emergency responders.

  • Helping explosive detection canine teams across the U.S.

    Dogs are uniquely suited to sniffing out explosives – their sense of smell is more than a million times stronger than a human’s. Harnessing this natural ability to help law enforcement identify explosives requires specialized training and testing. Many detection canine teams, however, have limited access to critical training materials and limited time to establish rigorous training scenarios. DHS S&T’s Detection Canine Program has developed an initiative to support these needs for the nation’s more than 4,000 explosives detection canine teams.

  • No funds for California's earthquake early-warning system in Trump's proposed budget

    The Trump administration’s proposed budget would eliminate federal funding for an earthquake early warning system being developed for the U.S. West Coast. Critics say that if the relevant clauses in the budget proposal become law, the long-planned seismic warning effort will be killed. Scientists say the withdrawal of federal funds would likely end the early-warning project, which aims to send smartphone tremor alert messages to West Coast residents.

  • Israel to install earthquake early-warning system

    Israel has selected Ottawa, Canada-based Nanometrics to build an earthquake early-warning system in Israel. The alert system will give a 10-to-30-second alert of an impending earthquake. The system’s success depends on the distinction between two types of waves an earthquake generates — P waves (for primary) and S waves (for secondary). P waves are very fast, traveling through rock at between four and seven kilometers per second, and are thus the first waves to arrive at a recording station following an earthquake. An S-wave has a shearing motion that makes the rock vibrate perpendicular to its path. This movement slows the S-wave, so that it travels at two to five kilometers per second, or about half the speed of the P-wave. It is S waves which are almost entirely responsible for the damage and destruction associated with earthquakes.

  • $2-million grant for training next generation of nuclear arms control experts

    Post-Cold War arsenal reductions by the United States and Russia have slowed, and both sides continue to keep many hundreds of weapons on hair trigger alert ready to launch within minutes of a country’s leader pushing the button. Meanwhile, concerns grow about nuclear programs in North Korea, South Asia, and the Middle East. Princeton University’s Program on Science and Global Security (SGS) has received a $2-million grant from the MacArthur Foundation. The award will support SGS’ efforts to educate and train the next generation of researchers and scientists studying nuclear non-proliferation, arms control and disarmament.

  • Argonne’s nuclear security training team has a global reach

    At Argonne National Laboratory, a team of experts is training foreign scientists and engineers in the peaceful uses of nuclear energy and technology. Although the building is more than 4700 miles from the headquarters of the International Atomic Energy Agency (IAEA) in Vienna, the team is helping it uphold decades of international nuclear cooperation. Over the years, Argonne has taught more than 220 courses to more than 5,000 students, many of whom became leaders of nuclear safety and security abroad.

  • U.S. nuclear watchdog greatly underestimates potential for nuclear disaster

    The U.S. Nuclear Regulatory Commission (NRC) relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from the occurrence of a catastrophic nuclear-waste fire at any one of dozens of reactor sites around the country, a new study shows. Fallout from such a fire could be considerably larger than the radioactive emissions from the 2011 Fukushima accident in Japan. These catastrophic consequences, which could be triggered by a large earthquake or a terrorist attack, could be largely avoided by regulatory measures that the NRC refuses to implement.

  • Mobile phones can reveal exposure to radiation

    In accidents or terror attacks which are suspected to involve radioactive substances, it can be difficult to determine whether people nearby have been exposed to radiation. But by analyzing mobile phones and other objects which come in close contact with the body, it is possible to retrieve important information on radiation exposure.

  • Bomb squads to compete in annual Robot Rodeo

    Robots are life-saving tools for bomb squads and emergency response teams, providing them a buffer from danger. Sandia National Laboratories is hosting the 11th annual Western National Robot Rodeo, a four-day event where civilian and military bomb squad teams get practice using robots to defuse diverse, dangerous situations.

  • Pocket-size biological solution to radioactive threats

    Yaky Yanay, co-CEO of Pluristem Therapeutics, last week surprised the participants The Jerusalem Post Annual Conference in New York by saying that a small glass vial he pulled out of his pocket offered a solution to Iran’s nuclear threats. “I have the solution in my pocket.” The company has developed an anti-radiation therapy that can be stockpiled for emergencies. The therapy harnesses the power of the human placenta to contain the cascading effect of radiation exposure in the body and allow for the natural healing of cells.

  • New plutonium discovery to help nuclear waste clean-up

    Plutonium has long been part of many countries’ nuclear energy strategies, but scientists are still unlocking the mysteries behind this complicated element and seeing how they can use heavier, nuclear elements to clean up nuclear waste. Now, new research shows that plutonium does not exactly work the way scientists thought it did. The findings will contribute to the effort to develop technologies to clean up nuclear waste.

  • Nuclear storage tunnel collapses at Washington State’s Hanford site; employees evacuated

    Hundreds of workers have been forced to “take cover” after a tunnel in a nuclear finishing plant collapsed at the Hanford Nuclear Reservation in southeastern Washington state. The Department of Energy activated its Emergency Operations Center following the collapse. Nuclear experts have criticized to storage and safety practices at the site, calling it “the most toxic place in America” and saying it was “an underground Chernobyl waiting to happen.”
