• Bolstering shipping security

    During a press conference following the March 2014 Nuclear Secu­rity Summit in the Hague, President Barack Obama noted that his biggest security concern was not Russia — or any other regional superpower — but rather “the prospect of a nuclear weapon going off in Manhattan.” Experts say that the most likely way in which a nuclear weapon would potentially come to a major U.S. city is not on the tip of a missile but in the belly of a ship, noting that this view has been openly validated by the intelligence community. In 2007, Congress passed a law requiring all overseas cargo containers to be inspected before they are loaded on a U.S.-bound ship. That law, however, has never been enforced.

  • South Carolina withdraws MOX lawsuit against DOE, NNSA

    The state of South Carolina said Friday that it would not go ahead with its lawsuit against the Department of Energy and the National Nuclear Security Administration (NNSA) in support of the Savannah River Site’s Mixed Oxide (MOX) Fuel Fabrication Facility. The dismissal of the lawsuit follows an announcement last Tuesday by the DOE and NNSA that construction will continue on the MOX facility through the end of the fiscal year. The two agencies made it clear, though, that they still plan to mothball the plant.

  • Lawmakers want DOE to reduce run-away costs of S.C. plutonium processing plant

    Lawmakers have given the Obama administration two weeks to submit a plan for reducing the cost of constructing the mixed-oxide fuel conversion (MOX) facility which would convert bomb-grade plutonium into nuclear fuel. The MOX facility at the Savannah River Site, South Carolina was launched to help the United States meet its nuclear arms reduction agreement with Russia, and agreement which called for the two countries to dispose of at least thirty-four metric tons each of weapons-grade plutonium.

  • Lawmakers urge NRC not to exempt shut-down nuclear plants from emergency, security regulations

    Lawmakers are urging the U.S. Nuclear Regulatory Commission (NRC) to halt exemption of recently- shuttered nuclear power plants from emergency-planning and security regulations. The lawmakers are especially concerned about the nuclear waste which will continue to be stored on the grounds of shut-down nuclear plants, saying that the stored radioactive waste continues to be a security threat whether or not the plant itself is still operational.

  • Birds in and around Chernobyl's exclusion zone adapting to ionizing radiation

    Birds in the exclusion zone around Chernobyl are adapting to — and may even be benefiting from — long-term exposure to radiation, ecologists have found. The study is first evidence that wild animals adapt to ionizing radiation, and the first to show that birds which produce most pheomelanin, a pigment in feathers, have greatest problems coping with radiation exposure.

  • Threats from insiders are the most serious security challenges nuclear facilities face

    Insider threats are the most serious challenge confronting nuclear facilities in today’s world, a new study says. In every case of theft of nuclear materials where the circumstances of the theft are known, the perpetrators were either insiders or had help from insiders, the study found. Theft is not the only danger facing facility operators; sabotage is a risk as well, the study authors say.

  • S.C. fights to keep costly plutonium processing project alive

    The United States and Russia have agreed to dispose of thirty-four tons of weapon-grade plutonium each, an amount equal to 17,000 nuclear warheads. The United States budgeted $4 billion for a mixed-oxide fuel project, known as MOX, at the Savannah River Site, S.C., to process the plutonium, but construction costs have now reached $8 billion, and officials estimate the facility will cost about $30 billion over its operating years. DOE has suspended the MOX project and is looking for alternative plutonium processing methods. South Carolina has sued the federal government, arguing that since Congress has authorized the funds for MOX, the administration must spend the money.

  • Some see small modular reactors as offering a better future for the nuclear industry

    A full-size reactor costs up to $8 billion, takes years to build, and decades to achieve a return on investment. Some experts say the future of the nuclear industry should be based on small underground reactors, which are cheaper and quicker to build. Other experts say that smaller reactors mean needing many more of them to produce the same amount of power as traditional reactors, and having more reactors means increasing security concerns.

  • Detecting and defeating radiological threats

    Brookhaven National Laboratory’s Radiological Assistance Program (RAP) team works to stay ahead of any radiological threats by using many detection tools that have become increasingly sophisticated and user-friendly. During a deployment, researchers and technicians with backgrounds in various aspects of radiological controls and analysis conduct field monitoring and environmental sampling, assessment, and documentation activities to help decision makers choose appropriate protective actions for the safety of both the public and first responders.

  • Debate over Ontario, Canada underground nuclear waste facility intensifies

    Ontario Power Generation’s (OPG) proposal to construct an underground nuclear waste disposal facility near the company’s Bruce Nuclear plantand on the edge of the Great Lakes is facing growing opposition from local municipalities and environmentalists. The facility would store low and intermediate nuclear waste from OPG’s Bruce, Pickering, and Darlington nuclear facilities. Environmentalists are concerned that a leak in the underground facility would be devastating for communities which depend on water from the Great Lakes.

  • NC State awarded $25 million NNSA grant to launch nuclear proliferation detection effort

    North Carolina State University was awarded a 5-year, $25 million grant by the National Nuclear Security Administration’s (NNSA) to develop the next generation of leaders with practical experience in technical fields relevant to nuclear nonproliferation. The new Consortium for Nonproliferation Enabling Capabilities, or CNEC, aims to be the pre-eminent research and education hub dedicated to the development of enabling technologies and technical talent for meeting the challenges of nuclear nonproliferation in the next decade.

  • New detection technology to help combat nuclear trafficking

    According to the International Atomic Energy Agency (IAEA), the greatest danger to nuclear security comes from terrorists acquiring sufficient quantities of plutonium or highly enriched uranium (HEU) to construct a crude nuclear explosive device. The IAEA also notes that most cases of illicit nuclear trafficking have involved gram-level quantities, which can be challenging to detect with most inspection methods. Special algorithm coupled with commercial X-ray scanners allows detection of small amounts of fissile materials in luggage.

  • Floating nuclear plants could ride out tsunamis

    When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused the ensuing contamination. Rather, it was the aftereffects — specifically, the lack of cooling for the reactor cores, due to a shutdown of all power at the station — that caused most of the harm. A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid such consequences in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material.

  • Debate over closing NY’s Indian Point nuclear power plant intensifies

    Indian Pointnuclear power plant, just thirty miles from New York City, has presented a conundrum for environmentalists who advocate clean-air initiatives, caps on carbon emissions, and increasing investment in non-polluting renewable energy sources — but at the same time argue that nuclear power poses a safety hazard to the surrounding area and demand that Indian Point cease operations. Closing the plant would require a long-term energy strategy to replace the 2,000 megawatts the plant currently produces.

  • New consortium dedicated to developing nuclear arms control verification technologies

    A consortium of thirteen universities and eight national laboratories, led by the University of Michigan and including the Los Alamos National Laboratory as a partner, has been awarded a $25 million grant by the NNSA. The consortium is dedicated to the research and development (R&D) of nuclear arms control verification technologies, including nuclear safeguards effectiveness.
