  • Service lives of European nuclear power stations to be extended

    Germany has decided to abandon nuclear energy – in what the Germans call Energiewende (energy turnaround) – but new nuclear power stations are being built on all sides of Germany and service lives for existing facilities on the territory of Germany’s neighbors are being extended. German nuclear scientists should thus continue to be involved in assessing the safety of the nuclear power stations in neighboring countries, especially so since the EU has launched its LONGLIFE project, which aims to extend the service life of existing reactors from forty to sixty or even eighty years.

  • NRC: storing spent nuclear fuel in cooling pools is safe

    The nuclear reactors now in service in the United States were built with the assumption that the spent fuel would be removed from nuclear the facilities after a few years, but because the government has failed to provide a centralized place to store the spent fuel, utility companies have had to store an ever-growing quantity of it in spent fuel pools on the grounds of the facilities. Scientists argue that it would be safer to move some of the spent fuel into giant steel and concrete casks, where it can be stored dry, with no reliance on water, pumps, or filters to keep them cool. The nuclear industry and the NRC do not agree.

  • Nations' nuclear ambitions not discouraged by few suppliers

    Twenty-nine countries are considering constructing their first nuclear power plant. There are doubts as to which of these nuclear “newcomer” countries can actually succeed and join the thirty-one countries that already operate nuclear reactors. If even half of the national plans for nuclear power plants materialize, the geography of nuclear energy would radically change and could revitalize a stagnant industry. But given the obstacles to starting a national nuclear power program even for rich and stable countries, it’s not likely to happen quickly elsewhere.

  • One step closer to nuclear fusion power station

    Researchers have made a technological breakthrough crucial to the success of nuclear fusion reactors, allowing for clean, inexhaustible energy generation based on the workings of the stars in our galaxy. At the heart of the new development is an ingenious and robust superconducting cable system. This makes for a remarkably strong magnetic field that controls the very hot, energy-generating plasma in the reactor core, laying the foundation for nuclear fusion. The new cables are far less susceptible to heating due to a clever way of interweaving, which allows for a significant increase in the possibilities to control the plasma.

  • U.S. loses clean electricity as nuclear power plants keep closing

    Four nuclear power plants, sources of low-emissions electricity, have announced closings this year. The main reason: the increasing availability of cheap natural gas as a result of fracking. If plants continue to shut down instead of extending operations, the United States risks losing 60 percent of its clean electricity starting in 2030, according to a new report by the American Physical Society (APS). The APS calls on socially responsible investors to encourage utilities to consider carbon emissions in business decisions.

  • Y-12 security breach update: Old nun awaits sentencing while costs of new Y-12 facility not to be released until 2015

    On 28 July 2012, three senior citizens, led by an 83-year old nun, easily breached the supposedly impregnable security systems protecting the Y-12 National Security Complex at Oak Ridge, Tennessee. The three peace activists wondered the grounds of the maximum security facility for a while before being noticed by security personnel. While the three aging protesters are awaiting sentencing, the two companies — Bechtel Corporation and Babcock and Wilcox – which were responsible for designing and implementing security at Y-12, have been named as the primary construction contractors for planning and design of the new uranium processing facility (UPF) to be built at Y-12.

  • The interim agreement between the P5+1 and Iran: the details

    The P5+1 countries (the United States, United Kingdom, Germany, France, Russia, and China, facilitated by the European Union) have been engaged in negotiations with Iran in an effort to reach a verifiable diplomatic resolution which would prevent Iran from obtaining a nuclear weapon. On Sunday, the P5+1 and Iran reached a set of initial understandings which halts, at least temporarily, the progress of Iran’s nuclear program and rolls it back in key respects. In return, for Iran’s concessions, and as part of this initial step, the P5+1 will provide what the agreement describes as “limited, temporary, targeted, and reversible” relief to Iran.

  • New drone to monitor radiation following nuclear disasters

    Researchers have unveiled a large semi-autonomous drone called the ARM system which could be used to provide visual and thermal monitoring of radiation after a release of nuclear material. The system was developed in response to requirements for radiation monitoring in event of the release of radioactive materials.

  • 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.
