• DOE to resume transient testing of nuclear fuels and materials

    Transient testing of nuclear fuel involves placing fuel or material into the core of a nuclear reactor and subjecting it to short bursts of intense, high-power radiation in order to analyze the effects of the radiation. The Idaho National Laboratory (INL) Transient Reactor Test Facility began operating on 23 February 1959 and was a principal reactor safety testing facility in the United States for thirty-five years. The U.S. Department of Energy invites the public to read and comment on a draft environmental assessment it has prepared for a proposal to resume transient testing of nuclear fuels and materials.

  • Japan hopes off-shore wind turbines can replace shut-down nukes

    Japan inaugurated a floating offshore wind turbine on Monday, symbolizing the country’s effort to reduce its dependency on nuclear energy and fossil fuels and shift to renewable energy sources. The floating platform is anchored thirteen miles offshore from the Fukushima Daiichi nuclear power plant, which has been out of commission since the reactor’s meltdown disasterof March 2011. The platform is anchored to the seabed 400 feet below surface. It is the first project of its kind in Japan, and it aims to show that the country can exploit the country’s powerful offshore winds to create a sustainable energy source.

  • Reducing volume of nuclear waste by 90 percent possible

    Engineers have developed a way significantly to reduce the volume of some higher activity wastes, which will reduce the cost of interim storage and final disposal. The researchers have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces its volume by 85-95 percent. It also effectively locks in the radioactive plutonium, creating a stable end product.

  • “Hybrid” nuclear plants could make a dent in carbon emissions

    Combining nuclear with artificial geothermal, shale oil, or hydrogen production could help slow climate change, study shows. MIT’s Charles Forsberg proposes marrying a nuclear powerplant with another energy system, which he argues could add up to much more than the sum of its parts.

  • China buys Implant Sciences explosives detectors to protect nuclear power plants

    Implant Sciences has sold multiple units of its QS-H150 handheld explosives trace detectors to a customer in China, who will be deploy them across several locations for the purpose of protecting nuclear power plants in multi-layered security environments.

  • Leading climate scientists urge support for nuclear power

    Four of the world’s leading climate scientists have urged environmentalists to support the continuing development of nuclear power as one of the ways to reduce fossil fuel pollution, saying wind and solar energy will not be enough to head off dangerous acceleration of global warming. This is an important point because environmentalists agree that global warming is a threat to ecosystems and humans, but many of the same environmentalists oppose nuclear power, arguing that new forms of renewable energy will be sufficient to meet the world’s need for power within the next few decades.

  • Where should U.S. radioactive waste be buried?

    In the United States, about 70,000 metric tons of spent commercial nuclear fuel are located at more than seventy sites in thirty-five states. Shales and other clay-rich (argillaceous) rocks have never been seriously considered for holding America’s spent nuclear fuel, but it is different overseas. France, Switzerland, and Belgium are planning to put waste in tunnels mined out of shale formations, and Canada, Japan, and the United Kingdom are evaluating the idea.

  • Russia to build floating nuclear power plants

    Global warming is opening the Arctic Ocean to shipping – and causing the rapid melting of Arctic ice. Russia says that ship-based nuclear power plants would allow it to provide power to remote cities in Siberia, and provide power to oil and gas drilling operations in the Arctic (about 30 percent of the world’s unclaimed natural gas is in the Arctic, and about, 60 percent of that unclaimed natural gas is in the Russian Arctic). Experts worry about the ability of ship-based nuclear reactor to withstand extreme weather events, or terrorist attacks. The U.S. Army deployed its own floating nuclear reactor – the Sturgis – in the Panama Canal Zone from 1968 to 1976.

  • Nuclear fuel withstands accident conditions’ high-temperature

    A safer and more efficient nuclear fuel is on the horizon. A team of researchers 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. Byproducts of the fission process have the potential to escape the fuel, especially at very high temperatures. Controlled, high-temperature testing of irradiated TRISO) fuel demonstrated that fission product release remains relatively low at high temperatures postulated to occur in accidents and beyond.

  • Sharp increase in radioactive water leaks at Fukushima

    Tokyo Electric Power(TEPCO) has reported a rise in groundwater radiation levels, saying a tank at the firm’s Fukushima plant leaked 300 metric tons of toxic water in August 2013. Water samples from wells, taken in mid-October, show a record-high concentration of beta-ray emitting substances, and a sharp increase in the presence of radioactive tritium. Japanese prime ministerShinzo Abe, in a tacit admission that Japan cannot effectively handle the continuing radiation leaks from the stricken plant, said Japan would be interested in receiving foreign help to contain widening radioactive water leaks at Fukushima.

  • U.S. first nuke in thirty years mired in costly legal wrangling

    The U.S. first nuclear construction project in thirty years is the center of a $900 million lawsuit pitting Westinghouse Electric Co. against Georgia Power. The $14 billion project is about twenty months behind schedule and $900 million over budget, and each side blames the other for the delays and cost overruns.

  • Irish heritage groups sues U.K. over nuclear power plant

    An Taisce, an Irish charity group promoting the preservation of Ireland’s heritage, is taking the British government to the High Court in London in December seeking a judicial review of the legality of British energy minister Ed Davey’s decision to approve the construction of a nuclear power plant just 150 miles from the Irish coast without consulting the Irish public.

  • 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.

  • 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.
