• Sandia transport triathlon puts spent nuclear fuel to the test

    Nuclear power supplies almost 20 percent of U.S. electricity and is the leading carbon-neutral power source. However, it produces between 2,200 and 2,600 tons of spent fuel in the United States each year. Fuel rods become brittle and highly radioactive while powering the nuclear reactor, making safe transportation important. Sandia National Laboratories researchers completed an eight-month, 14,500-mile triathlon-like test to gather data on the bumps and jolts spent nuclear fuel experiences during transportation.

  • Pipe-crawling robot to help decommission DOE nuclear facility

    A pair of autonomous robots developed by Carnegie Mellon University’s Robotics Institute will soon be driving through miles of pipes at the U.S. Department of Energy’s former uranium enrichment plant in Piketon, Ohio, to identify uranium deposits on pipe walls. The CMU robot has demonstrated it can measure radiation levels more accurately from inside the pipe than is possible with external techniques.

  • Expanding real-time radiological threat detection to include other dangers

    Advanced commercially available technologies—such as additive manufacturing (3-D printing), small-scale chemical reactors for pharmaceuticals, and CRISPR gene-manipulation tools—have opened wide access to scientific exploration and discovery. In the hands of terrorists and rogue nation states, however, these capabilities could be misused to concoct chemical, biological, radiological, nuclear, and high-yield explosive (CBRNE) weapons of mass destruction (WMD) in small quantities and in form factors that are hard to detect. DARPA’s SIGMA+ program aims to create additional sensors and networks to detect biological, chemical, and explosives threats.

  • DTRA awards British university $1.1 million for improved radiation detectors

    The University of Surrey has been awarded $1.1 million by the U.S. Defense Threat Reduction Agency (DTRA) to research new types of nanomaterials that produce high efficiency radiation detectors for use in nuclear security. The project will develop materials that are used as highly sensitive radiation detectors.

  • New evidence of nuclear fuel releases discovered at Fukushima

    Uranium and other radioactive materials, such as cesium and technetium, have been found in tiny particles released from the damaged Fukushima Daiichi nuclear reactors. This could mean the environmental impact from the fallout may last much longer than previously expected according to a new study by a team of international researchers. The team says that, for the first time, the fallout of Fukushima Daiichi nuclear reactor fuel debris into the surrounding environment has been “explicitly revealed” by the study.

  • Quicker response to airborne radiological threats

    Researchers have developed a new technique that uses existing technologies to detect potential airborne radiological materials in hours instead of days. at present, emergency responders who are characterizing potential radiological risk need to take an air sample and ship it to a radiochemistry lab after preliminary screening analysis. The process means it can take days or weeks to get quality results that authorities can use to make informed decisions.

  • The sound and the fury: Inside the mystery of the Havana embassy

    More than a year after American diplomats began to suffer strange, concussion-like symptoms in Cuba, a U.S. investigation is no closer to determining how they were hurt or by whom, and the FBI and CIA are at odds over the case. A ProPublica investigation reveals the many layers to the mystery — and the political maneuvering that is reshaping U.S.-Cuba relations.

  • The man who knew too much

    In November 2006, on orders of Vladimir Putin, Russian operatives used radioactive material to poison and kill Alexandr Litvinenko, a former KGB colleague who had turned a fierce critic of the Russian leader, and who was living with his family in London. Yesterday, the British government froze the assets of the two Russian agents – one of them has been awarded a medal by Putin, and is now a leading member of United Russia, Putin’s political party, in the Russian parliament. Ten years later, in November 2016, a leading British nuclear forensic scientist – who was part of the 2006 investigation and who was instrumental in tying the nuclear material used in the killing to the two Russian agents — was found dead in his home, after returning from an academic research trip to Russia. It was the 14th Russia-related killing on British soil since 2006. The number of individuals with inside knowledge of the Putin regime and its practices — and who have met an untimely end in mysterious circumstances — is growing, and British lawmakers urge the government to show more resolve in investigating this string of killings.

  • DHS establishes the Countering Weapons of Mass Destruction office

    Secretary of Homeland Security Kirstjen Nielsen last week announced the establishment of the Department of Homeland Security’s (DHS) Countering Weapons of Mass Destruction (CWMD) Office. DHS says that the CWMD Office will elevate and streamline DHS efforts to prevent terrorists and other national security threat actors from using harmful agents, such as chemical, biological, radiological, and nuclear material and devices to harm Americans and U.S. interests.

  • U.S. medical profession unprepared for nuclear attack: Study

    Escalating tensions between Washington and Pyongyang over North Korea’s nuclear program have fueled concerns about the possibility of nuclear warfare, and a new study has found that American medical professionals are woefully unprepared to handle the needs of patients after a nuclear attack. “I was not surprised that the responses from the emergency medical community were relatively poor in terms of knowledge and attitudes, because that’s what you get with radiation-myths versus reality,” said the study’s lead author.

  • Evacuating a nuclear disaster area is often a waste of time and money, says study

    Over 110,000 people were moved from their homes following the Fukushima nuclear disaster in Japan in March 2011. Another 50,000 left of their own will, and 85,000 had still not returned four-and-a-half years later. While this might seem like an obvious way of keeping people safe, my colleagues and I have just completed research that shows this kind of mass evacuation is unnecessary, and can even do more harm than good. We calculated that the Fukushima evacuation extended the population’s average life expectancy by less than three months. The reality is that, in most cases, the risk from radiation exposure if tpeople stay in their homes is minimal. It is important that the precedents of Chernobyl and Fukushima do not establish mass relocation as the prime policy choice in the future, because this will benefit nobody.

  • Radioactive material, leaked from a Russian nuclear complex, detected over Europe

    The Russian state meteorological agency Roshydromet today released data which show exceedingly high atmospheric concentration of ruthenium-106 in the area where the Rosatom Mayak nuclear complex, located in the Southern Urals. The late-September leak, initially denied by Roasatom, the operator of the complex, caused the radioactive material to spread over northern Europe, where it was detected by IRSN and BfS, the French and German nuclear safety agencies, respectively.

  • Investigating the effectiveness of nanoscale nuclear waste filter

    Nuclear power accounts for roughly 11 percent of the world’s electricity, and researchers are examining more efficient and less expensive methods of capturing radioactive iodine and other common byproducts from the reactors. Researchers are investigating the effectiveness of a nanoscale “sponge” that could help filter out dangerous radioactive particles from nuclear waste.

  • New theory of the opening moments of Chernobyl disaster

    Researchers, relying on new evidence and analysis, have come up with a new theory of the opening moments during the Chernobyl disaster, the most severe nuclear accident in history. The new theory suggests the first of the two explosions reported by eyewitnesses was a nuclear and not a steam explosion, as is currently widely thought.

  • Detecting nuclear materials used in dirty bombs

    Radiological material falling into the wrong hands is a constant security concern for governments around the world. Border agencies must scan incoming vehicles and freight for radioactive material, which is a challenging task, as huge volumes of both move across borders each day. Imperial College London’s physicists have developed two devices for detecting nuclear materials.
