• News coverage of Fukushima disaster inadequate

    Five years after the 2011 Fukushima Daiichi nuclear disaster in Japan, the disaster no longer dominates U.S. news headlines, although experts say it is a continuing disaster with broad implications. A new analysis finds that U.S. news media coverage following the disaster minimized health risks to the general population.

  • The lasting legacies of Chernobyl and Fukushima

    It is thirty years since the Chernobyl nuclear disaster. It is also five years since the Fukushima disaster. Greenpeace says that to mark these anniversaries, it has commissioned reviews of scientific studies examining the continued radioactive contamination in the affected areas, and the health and social effects on the impacted populations.

  • Secretive Area 6 used to test aerial radiation detection equipment

    Top-secret Nevada site – even more secret than neighboring Area 51 — is used by Pentagon, DHS to test drones equipped with sensors to detect radioactive material which could be used in dirty bombs. The site, located in Yucca Flat, was once used for nuclear testing.

  • Fukushima five years on: Three lessons from the disaster

    It has been five years since the emergency sirens sounded at Japan’s Fukushima Daiichi power plant following the massive 2011 earthquake and subsequent devastating tsunami. The partial meltdown of three reactors caused approximately 170,000 refugees to be displaced from their homes, and radiation releases and public outcry forced the Japanese government to temporarily shut down all of their nuclear power plants. On the fifth anniversary of the partial meltdown at Japan’s Fukushima Daiichi Power Plant, Stanford’s Rodney Ewing says we should rethink our language, reassess natural disaster risks, and appreciate the links between nuclear energy and renewables.

  • Bird droppings caused N.Y. nuclear reactor power outage

    On 14 December, one of the nuclear reactors at Indian Point nuclear power plant outside New York City was safely shut down for three days, following an electrical disturbance on outdoor high voltage transmission lines. Outside experts investigating the incident found the bird droppings were the cause of the electrical disturbance.

  • 2014 French nuclear accident more serious than official reports suggested

    German media charges  that the French nuclear authority and the French company operating the aging Fessenheim nuclear facility in France, concealed the seriousness of the April 2014 incident at the site. The French nuclear authorities withheld information not only from the German government, but also from the IAEA, to which they were required to submit a detailed report about the incident.

  • Truck carrying toxic nuclear materials stolen in Mexico

    Five Mexican states have been placed on a state of alert after a truck carrying a container of dangerous radioactive material was stolen, the Mexican Interior Ministry has said. The material could cause permanent or serious injury to a person who is in contact with it for a short time, and is fatal when exposure lasts for more than a few hours.

  • Air data can be used to reconstruct radiological releases

    New research demonstrates that experts can use data from air sampling technology to not only detect radiological releases, but to accurately quantify the magnitude and source of the release. This has applications for nuclear plant safety, as well as national security and nuclear nonproliferation monitoring.

  • U.S. testing radiation therapy developed in Israel

    The United States will likely begin to stock anti-radiation therapy from Pluristem Therapeutics Inc., an Israeli biotech company. The company says that the therapy can also cure nearly all people exposed to the radiation effects of nuclear weapons, “dirty” bombs, or nuclear power plants.

  • Nuclear forensics support law enforcement, national security investigations

    According to the IAEA, in the period from 1993 to 2013, sixteen confirmed incidents involved the unauthorized possession of HEU or plutonium. Researchers have just published an overview of nuclear forensics, including examples of key nuclear forensic signatures that have allowed investigators to elucidate the history of unknown nuclear material and describing how nuclear forensics supports law enforcement and national security investigations.

  • Predicting clay swelling for better nuclear waste disposal

    Bentonite clay is planned to be used as a key barrier in the deep geological disposal of high-level nuclear waste. To ensure the safety of disposal, it is crucial to understand and predict the swelling behavior of bentonite clay. The swelling property, however, is regulated by multiple structural and environmental factors. A new model simulates the atomic-level interactions among the components of clay-water system, reproducing the swelling trends and swelling pressures measured by experiments with good accuracy.

  • ISIS may get its hands on “highly dangerous” nuclear material stolen in Iraq

    Iraqi security agencies are searching for “highly dangerous” radioactive material stolen last year.  Experts are worried that the material could fall into the hands of ISIS. The material – Ir-192 — is designated a Category 2 radioactive by the IAEA, and it could be used to build a “dirty bomb,” which combines nuclear material with conventional explosives to contaminate an area with radiation.

  • Ending civilian use of highly enriched, weapon-grade uranium

    Efforts to convert civilian research reactors from weapon-grade highly enriched uranium (HEU) to low enriched uranium (LEU) fuels are taking significantly longer than anticipated, says a report from the National Academies of Sciences. The report calls for the federal government to take immediate steps to convert civilian research reactors currently using weapon-grade HEU fuel to a lower-enriched HEU fuel while awaiting the qualification of new LEU fuel.

  • Specialized ORNL team uses nuclear forensics to solve mysteries, safeguard materials

    From the Manhattan Project in the 1940s to the High Flux Isotope Reactor’s 50th anniversary and its selection as an American Nuclear Society Nuclear Historic Landmark, the Department of Energy’s Oak Ridge National Laboratory (ORNL) has been the preeminent destination for nuclear R&D. A group of nuclear detectives at ORNL) takes on tough challenges, from detecting illicit uranium using isotopic “fingerprints” to investigating presidential assassination conspiracies.

  • Symetrica inaugurates Radioactive Threat Verification Solutions Hub

    Southampton, U.K.-based Symetrica has inaugurated the company’s new Radioactive Threat Verification (RTV) Solutions Hub. The company says that the new facility will improve the company’s ability to support the global security community – including the U.K.’s Home Office and Border Force, the U.S. Department of Homeland Security, and other border protection agencies.
