• Better protective shield material for nuclear waste

    The integrity and survivability of a nuclear waste package is critically important in the transport of nuclear fuel and high-level waste. Research are working on developing an outer shield material for use in packaging which is resistant to corrosion, radiation, diffusion, and thermal cycling processes that affect fuel packages during long-term storage. The material will also need to be wear-tolerant and mechanically robust so that it can survive repeated handling and transportation.

  • U.S. nuclear power industry facing growing challenges

    The U.S. nuclear industry is scaling back expectations on the future of the industry, expectations which only a few were soaring. The availability of cheaper energy alternatives, a growing trend toward energy conservation, and renewed safety and health worries as a result of the 2011 Fukushima Daiichi Nuclear Power Plantaccident, are all reasons for why active nuclear plants are being forced to close, and why fewer energy companies are investing in new nuclear plants or upgrading existing ones.

  • Compound derived from vegetables offers shield from lethal radiation doses

    Researchers say a compound derived from cruciferous vegetable such as cabbage, cauliflower, and broccoli protected rats and mice from lethal doses of radiation. The compound, known as DIM could protect normal tissues in patients receiving radiation therapy for cancer, but could also protect individuals from the lethal consequences of a nuclear disaster.

  • Debate heats up over N.Y.’s Indian Point nuke license renewal

    Indian Point nuclear power plant, located twenty-four miles north of New York City, provides 25 percent of the power used in New York City and Westchester County. The plant’s two reactors were built four decades ago, and the plant operator is seeking a 20-year license renewal for them, or they will have to be shut down. Opponents of the license renewal point to the risk inherent in operating aging reactors – and to a recently discovered risk: Indian Point is located near two active seismic areas — the Ramapo Fault Plain and the Peekskill-Stamford line.

  • Arktis closes $2 million financing round

    Zürich, Switzerland-based Arktis Radiation Detectors Ltd., developer of a proprietary fast neutron detection technology which offers an innovative detection method for discovering well-shielded nuclear materials, successfully closed a round of financing worth $2 million.

  • Costly DOE uranium processing facility questioned

    The cost of a proposed Department of Energy’s uranium processing facility for nuclear weapons at theY-12 National Security Complex in Oak Ridge, Tennessee has increase nineteen times – from the original estimate of $600 million to $11.6 billion. If these estimates are accurate, the processing facility would entail one the largest investments in the U.S. nuclear weapons infrastructure since the Manhattan Project.

  • $5 million NSF grant focuses on nuclear threat inspection

    Penn State University has received a 5-year grant from the National Science Foundation (NSF) and DHS for nuclear threat inspection, as part of a team led by the Massachusetts Institute of Technology and including Georgia Tech. The grant will help develop new systems and sensors that will help detect nuclear weapons, special nuclear materials, radiation dispersal devices, and related threats.

  • Preventing nuclear terrorism

    Nuclear terrorism remains a real and urgent threat. Despite an array of mechanisms established to combat this threat, several serious problems persist, requiring relentless attention and actions by the United States, Russia, and other responsible nations. These problems include continuing nuclear security vulnerabilities in a number of countries and the continued incidents of illicit trafficking in nuclear materials, radioactive sources, and the various components.

  • Robust fourth-generation nuclear fuel withstands high-temperature accident conditions

    A safer and more efficient nuclear fuel is on the horizon. A team of researchers at the U.S. Department of Energy’s Idaho National Laboratory (INL) and Oak Ridge National Laboratory (ORNL) have reached a new milestone with tristructural-isotropic (TRISO) fuel, showing that this fourth-generation reactor fuel might be even more robust than previously thought.

  • Iran indicates willingness to rethink nuclear program in exchange for sanction relief

    As part of a series of steps designed to present post-election Iran as more pragmatic, President Hassan Rouhani and his advisers indicated they would be willing to consider curbs on Iran’s nuclear program in exchange for relief from the crippling economic sanctions imposed on Iran. Some Western experts say that all these steps are more than mere cosmetic changes, while skeptics note that Obama has reached out to Iran before, with no results. Veterans of past nuclear negotiations with Iran also noted that it is likely that Rouhani’s team may not yet fully understand the kinds of concessions that the Islamic republic would be required to make to have the most painful economic sanctions lifted.

  • Improving nuclear waste repositories

    How fast will iodine-129 released from spent nuclear fuel move through a deep, clay-based geological repository? Understanding this process is crucial. Countries worldwide consider underground clay formations for nuclear waste disposal because clay offers low permeability and high radionuclide retention. Even when a repository is not sited in clay, engineered barriers often include a compacted buffer of bentonite, a common type of clay, to improve waste isolation.

  • Children living close to nuclear power plants do not have higher risk of developing leukemia

    Young children who live near nuclear power plants do not have a greater risk of developing childhood leukemia or non-Hodgkin Lymphoma according to new research. Researchers conducted a study of almost 10,000 children under five years of age who were diagnosed with leukemia or similar cancers in Britain between 1962 and 2007. The scientists measured the distance from the nearest nuclear power plant both at birth and when diagnosed with childhood leukemia or non-Hodgkin lymphoma, and found that there was no apparent extra risk living near a nuclear power plant.

  • Fukushima radioactive plume to reach U.S. next year

    The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the United States within three years from the date of the incident, but is likely to be harmless, according to a new study. While atmospheric radiation was detected on the U.S. west coast within days of the incident, the radioactive particles in the ocean plume take considerably longer to travel the same distance.

  • Long-term radiation effects: Chernobyl’s lessons for Fukushima

    The Fukushima Daiichi nuclear disaster spread significant radioactive contamination over more than 3,500 square miles of the Japanese mainland in the spring of 2011. Now several recently published studies of Chernobyl are bringing a new focus on just how extensive the long-term effects on Japanese wildlife might be.

  • U.S. nuclear reactors vulnerable to terrorist attack: study

    More than ten years after the 9/11 hijackers considered flying a fully loaded passenger jet into a Manhattan area nuclear reactor, U.S. commercial and research nuclear facilities remain inadequately protected against two credible terrorist threats — the theft of bomb-grade material to make a nuclear weapon, and sabotage attacks intended to cause a reactor meltdown. A new report finds that none of the 104 commercial nuclear power reactors in the United States is adequately protected — but among the most vulnerable are eleven reactors in California, Connecticut, Florida, Maryland, Massachusetts, Missouri, New York, North Carolina, Texas, and Virginia. One of these reactors, on the grounds of the National Institute of Standards and Technology (NIST), is among the three research reactors fueled with bomb-grade uranium, and is located in the Washington, D.C. suburb of Gaithersburg, less than twenty-five miles from the White House.
