• Sandia Labs refurbishes nuclear security infrastructure

    Sandia National Laboratories has completed $199 million in facilities construction and repair as part of an 11-year national effort to revitalize the physical infrastructure of nuclear security enterprise sites. The work is part of a program established in 2001 to reduce a long-standing backlog of deferred maintenance at the National Nuclear Security Administration’s (NNSA) eight sites, including Sandia.

  • New explosives vapor detection technology

    Novel explosives detection method focuses on direct, real-time vapor detection rather than collection of explosives particles. It could change paradigm for explosives screening.

  • Defusing the threat of ionizing radiation

    The damage to Japan’s Fukushima nuclear reactor after the 2011 Tohoku earthquake raised concerns regarding U.S. preparedness to treat large-scale human exposure to ionizing radiation. Additionally, the immediate destructive potential of nuclear and radiological weapons, as well as their long-term health and economic impacts, continue to be of concern to DoD. Researchers look for  novel approaches to mitigate immediate and long-term health damage from acute exposure to ionizing radiation and model its biophysical effects.

  • Improving detection of, responses to biological warfare

    Biological warfare agents pose more than a hypothetical threat to U.S. soldiers. Troops operate in hostile areas where they could come under attack from adversaries wielding bio-agents like anthrax and toxins. The first step in reacting to any such attack is knowing that it occurred. Quickly and accurately identifying the presence of airborne antigens can be difficult given their complexity, the presence of numerous similar microorganisms in the environment, and the fact that even minute quantities of a threat agent can cause infection. Researches seek to advance sensitivity and durability of antibody-based biosensors better to protect soldiers.

  • Keeping an eye on the world’s dangerous chemicals

    In the chemistry labs of the developing world, it is not uncommon to find containers, forgotten on shelves, with only vague clues to their origins. The label, if there is one, is rubbed away. Left alone for years, some chemicals can quietly break down into explosive elixirs, and what was once an innocent experiment by a well-meaning scientist becomes a very real, unsecured threat. Should such chemicals fall into malicious hands, the consequences could be widespread and deadly.

  • Idaho debating nuclear waste storage

    For two decades, the Yucca mountain nuclear waste repository in Nevada was viewed as a long-term solution to the growing problem of radioactive waste generated by the 104 active nuclear power generation plants in the United States. One of the Obama administration’s first acts was to “defund” the project, in effect outing an end to it. States such as Texas, New Mexico, and North Carolina have fashioned their own interim solution to the problem of nuclear waste storage, and the governor of Idaho wants his state to follow these states’ example.

  • Promising substance for better cyanide antidote for terrorist attacks

    In an advance toward closing a major gap in defenses against terrorist attacks and other mass casualty events, scientists are reporting discovery of a promising substance that could be the basis for development of a better antidote for cyanide poisoning.

  • Increasing the sensitivity of airport security screening

    The latest episode in the American Chemical Society’s (ACS) Global Challenges/Chemistry Solutions podcast series reports a simple way to improve the sensitivity of the test often used to detect traces of explosives on the hands, carry-ons, and other possessions of passengers at airport security screening stations.

  • Part Three: Bechtel and the Y-12 security breach

    With an annual security budget of $150 million, the Y-12 Nuclear Complex at Oakridge, Tennessee, prided itself on its high-tech security system built to protect more than 179 tons of uranium. After Sister Megan Rice, age 82, and two confederates, both senior citizens, too — the three were armed with nothing but wire cutters and flashlights — broke into the Y-12 facility on 28 July 2012, one security guard was fired. Numerous investigations and reports, however, show that last July’s incident was but one in a series of security failures and breaches at nuclear sites under the supervision of the National Nuclear Security Administration (NNSA). In May, Sister Rice and her aging collaborators will stand trial. Bechtel, a major contractor sharing responsibility for the documented security lapses at Y-12, has just received a federal nuclear plant security contract worth more than $22 billion.

  • Uranium mining debate divides Virginia

    In Virginia a fight has begun over whether to drill for uranium. Some feel the drilling, which would create about 1,000 jobs and bounty of tax revenue in addition to nuclear fuel, is important for a state whose main industries, such as tobacco and textiles, are failing. Those who oppose the drilling fear the contamination of drinking water in case of an accident, and a stigma from uranium which would deter people and businesses from moving to the area.

  • Thorium holds promise of safer, cleaner nuclear power

    Thorium as nuclear fuels has drawbacks, but its main advantage includes generating far less toxic residue. The majority of the mineral is used during the fission process, and it can burn existing stockpiles of plutonium and hazardous waste, saving the need to transport it and bury the waste in concrete. If thorium becomes available as a source of energy in the future, the world will rely less on coal and gas, and wind turbines will become a thing of the past. The risk of a global energy crunch will decrease considerably.

  • Revealing full-body scanners to be removed from airports

    One of the more controversial post-9/11 security devices, the ubiquitous and uncomfortably intrusive full-body scanners, will be removed from service by the Transportation Security Administration (TSA). On Friday, the agency announced it would begin to remove the scanners from U.S. airports this summer. The anatomically revealing backscatter scanners are being replaced by the ore discreet millimeter wave devices.

  • Metamaterial sensor improves security, collision avoidance

    Engineers have developed a novel sensor which is more efficient, versatile, and cheaper for potential use in such applications as airport security scanners and collision avoidance systems for aircraft, cars, or maritime vessels.

  • Neutralizing the effects of lethal chemical agents

    Organophosphorus agents (OPs) are used both in farm pesticides, and by terrorists and rogue states. About 200,000 people die each year across the world from organophosphorus agents (OP) poisoning, through occupational exposure, unintentional use, and misuse, mostly in developing countries like India, Pakistan, and Sri Lanka and through deliberate terrorist activities. OPs include compounds like Tabun, which was developed in 1936 by German scientists during the Second World War, Sarin, Soman, Cyclosarin, VX, and VR. Researchers develop an enzyme treatment which could neutralize the effects of OPs.

  • U.K. revises nuke emergency plans post-Fukushima

    The Sizewell nuclear power station in Suffolk, England, was decommissioned in 2006, but after the 2011 Fukushima disaster, the Suffolk authorities thought there was a need to upgrade the emergency plans for the people living around the plant. There are disagreements, however, over the radius of the emergency zone around the plant, and how many people should be included i evacuation plans and given potassium iodide tablets in the event of a radiation leak.
