  • Idaho bolsters the state’s cyber defenses

    Idaho’s director of the Bureau of Homeland Security says that cyber threats remain the most important yet least understood risk to government and the private sector. He has announced plans to tackle that vulnerability in the state. The director of the Bureau says that cybersecurity will never be perfect, which makes it imperative for organizations like the Idaho Bureau of Homeland Security to focus on planning that incorporates not just defense, but also detection and the mitigation of damage that has already occurred.

  • Patriot Act’s reauthorization an obstacle for cyber information sharing bill

    Recent cyber hacking incidents have persuaded lawmakers to pass a cyber information sharing bill which will help protect U.S. private sector networks. Business groups and federal intelligence agencies insist that information exchange is critical to protecting the nation’s cyber infrastructure. One of the hurdles to passing such a bill is that by 1 June, Congress must reauthorize sections of the Patriot Act which are the basis for the NSA’s most controversial surveillance programs. Many lawmakers consider NSA reform to be essential before they can support the White House’s cybersecurity proposal, which would allow cyber information sharing between the public and private sector.

  • Studying cancer risks near nuclear facilities

    The National Academy of Sciences has issues a brief report which provides an expert committee’s advice about general methodological considerations for carrying out a pilot study of cancer risks near seven nuclear facilities in the United States. The pilot study will assess the feasibility of two approaches that could be used in a nationwide study to analyze cancer risk near nuclear facilities regulated by the U.S. Nuclear Regulatory Commission (NRC).

  • If South Korea’s nuclear plant staff are vulnerable, then so are the reactors

    Does it matter that a South Korean nuclear plant was hacked and plans of the complex stolen? As it is South Korea that’s the subject of this latest attack, everyone tends to assume it must have had something to do with North Korea. With a target as sensitive as a nuclear power plant, not unreasonably people are asking if safety could be compromised by a cyberattack. Could hackers cause the next Chernobyl or Three Mile Island? This points to an important and infrequently discussed problem, the vulnerability of critical national infrastructure. Cyber-attacks like these are a great way of levelling the playing field: why invest in massively expensive nuclear weapons program if you can simply shut down your enemies’ power, gas, water, and transportation systems? Increasingly more and more infrastructure is connected to the Internet, with all the security risks that entails.

  • Industry: Multiple redundant and back-up systems make nuclear plants safer than ever

    Nuclear plants receive what supporters of nuclear power regard as an unfair amount of scrutiny and concern for their safety, but industry experts say that plant equipment and plant operations are highly regulated to minimize risks.All U.S. nuclear plants are now storing emergency pumps, generators, battery banks, chargers, compressors, and hoses at off-site locations near the plants to protect against floods, industry insiders say.Working in a nuclear plant is much safer than working in a paper mill or a chemical plant, according to Jim Krafty, a Nuclear Regulatory Commission (NRC) resident senior inspector at the Beaver Valley nuclear power plant in Shippingport, Pennsylvania.

  • Nuclear power should play “substantial role” in mitigating climate change: Environmental scientists

    Leading conservation scientists from around the world have called for a substantial role for nuclear power in future energy-generating scenarios in order to mitigate climate change and protect biodiversity. In an open letter to environmentalists with more than sixty signatories, the scientists ask the environmental community to “weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is ‘green’.”

  • Ultrasonic robot inspects pipes at nuclear power plant

    See video

    GE Hitachi Nuclear Energy (GEH) the other day announced that its ultrasonic robot, Surveyor, successfully inspected a section of underground pipe at the South Texas Project Electric Generating Station. The inspection at the site of two Westinghouse-built pressurized water reactors near Bay City, Texas, marks the first deployment of the state-of-the-art robot at a nuclear power plant.

  • SCE&G places 180,000-pound CA05 module at V.C. Summer Unit 2, S.C.

    South Carolina Electric & Gas Company (SCE&G) and its partners placed on 6 December the CA05 structural module on the V.C. Summer Unit 2 nuclear island. The company says this is one of several milestones achieved this year in the construction of nuclear reactors that are among the first in the U.S. in thirty years.

  • Improving nuclear power plant safety by looking at nature

    Within the nuclear industry, hazardous salt solutions can arise within industrial containment vessels. The salt solution precipitates out, forming structures with strange morphologies that bear a resemblance to stalagmites. If left unchecked, they could build up and cause a problem in the nuclear containment chamber. Currently, these containment chambers are checked regularly to prevent this from happening. Taking inspiration from nature, researchers have created a versatile model to predict how stalagmite-like structures form in nuclear processing plants — as well as how lime scale builds up in kettles.

  • Risks of terrorists attacking, or using materials from, a nuclear power plant are low: Experts

    Energy analysts who support new nuclear power plants construction insist that the probability of a terrorist nuclear attack by land, sea, or air is extremely low. They reject arguments by nuclear power opponents that terrorist groups may one day attack a nuclear plant, or build an improvised nuclear bomb using materials stolen from a nuclear power plant – and that governments should, therefore, end construction of new nuclear power plants. Climate scientists supporting reduction in CO2 emissions wrote that “There is no credible path to climate stabilization that does not include a substantial role for nuclear power.”

  • Washington State supports new Hanford project, but worries about cost

    The state of Washington is supporting a new facility which would lessen the load on the Hanford vitrification (vit) plant to process nuclear waste, but has expressed concerns about how the U.S. Department of Energy (DOE) will pay for the project. Only rough estimates of the cost of the project – called LAWPS, or the Low-Activity Waste Pretreatment System — have been made, but these estimates run between $243 million and $375 million, though that number does not include infrastructure costs such as the addition of roadways and utility services.

  • New light shed on reactor fuel behavior during severe nuclear reactor accidents

    UO2 is the primary fuel component in the majority of existing nuclear reactors, but little is known about the molten state because of its extremely high melting point. Until now, the extremely high temperature and chemical reactivity of the melt have hindered studies of molten UO2. This lack of fundamental information has made it difficult to evaluate issues associated with the interaction of molten UO2 with a reactor’s zirconium cladding and steel containment vessel. A new discovery about the atomic structure of uranium dioxide will help scientists select the best computational model to simulate severe nuclear reactor accidents.

  • U.S. planning expansion of nuclear production in the face of safety concerns

    Despite the release of a damning report regarding the 14 February nuclear waste accident at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico by the U.S. Department of Energy (DOE), the government is planning ramped-up production of nuclear weapons cores, a move which is raising red flags for those calling for reform of nuclear production and storage procedures.

  • A second drum at nuke waste repository poses radiation leak danger

    At a recent meeting of the New Mexico Legislature’s Radioactive and Hazardous Materials Committee in Carlsbad, officials were informed that a second waste drum containing nuclear materials, could also contain the same mix of ingredients as the waste drum from Los Alamos National Laboratory (LANL) which caused a radiation leak at the Waste Isolation Pilot Plant (WIPP) in February.

  • Preparing the next generation of nuclear emergency responders

    The catastrophic failure of Japan’s Fukushima I Nuclear Power Plant in March 2011 was a turning point in how the scientific community viewed nuclear emergencies. Up to then, the emphasis had been on prevention, not response. Virginia Tech’s Sonja Schmid has won a 2014 National Science Foundation Faculty Early Development (CAREER) Award to study the prospects and problems of creating a global nuclear emergency response plan. Key issues to be addressed in her research are how to convince the world that any nuclear accident is everybody’s problem and how to mobilize an effective international response.
