• Switzerland mulls its energy future

    Switzerland has a long history of trying to be as self-sufficient and energy independent as possible. Although its energy supply system has served it well in the past, the country is now looking to turn away from its reliance on nuclear power, at the same time that it is seeking to compensate for the energy lost from hydropower as a result of climate change.

  • A new look for nuclear power

    Many experts cite nuclear power as a critical component of a low-carbon energy future. Nuclear plants are steady, reliable sources of large amounts of power; they run on inexpensive and abundant fuel; and they emit no carbon dioxide (CO2). A novel nuclear power plant that will float eight or more miles out to sea promises to be safer, cheaper, and easier to deploy than today’s land-based plants.

  • Iran offered nuclear help in exchange for tighter restrictions on weapons-related technology

    The talks between the P5+1 and Iran over a nuclear deal resumed on Wednesday, and sources say that Western powers have offered Iran high-tech reactors in exchange for further curbs on those aspects of Iran’s nuclear program which would make it possible for it to “break out” of the confines of the deal and build a nuclear weapon. The Western powers promised to supply Iran with light-water nuclear reactors instead of its nearly completed heavy-water facility at Arak, which could produce enough plutonium for several bombs a year if completed as planned. One of the major goals of the P5+1 negotiators has been to reduce the Arak reactor’s plutonium output, thus blocking Iran’s plutonium path to the bomb. It offers cooperation with Iran in the fields of nuclear safety, nuclear medicine, research, nuclear waste removal, and other peaceful applications.

  • New reactor design recycles nuclear waste

    One of the major technological hurdles for nuclear energy is developing systems to dispose of the waste produced by typical reactors. It must be sealed away for hundreds of millennia while the radioactivity naturally decreases. An advanced nuclear reactor under development by Hitachi could help solve the nuclear waste problem. Hitachi’s new design would burn off the longest-lived radioactive materials, called transuranics, shortening that isolation period to a few centuries. This would recycle the nuclear waste to produce yet more energy and reduce the amount that must be stowed away.

  • NRC ruling raises questions about future of Diablo Canyon reactors

    In a major victory for those who pointed, post-Fukushima, to the risks involved in having a nuclear power reactor operating too close to a seismic fault, as is the case with the Diablo Canyon nuclear reactors, U.S. Nuclear Regulatory Commissioners have ruled – in a decision that could mark the beginning of the end of Diablo Canyon — that an Atomic Safety Licensing Board will decide whether Pacific Gas & Electric Co. was allowed illegally to alter the plant’s license. This alteration was made in an effort to hide the risk from powerful earthquake faults discovered since it was designed and built.

  • More proof needed that PG&E’s Diablo Canyon nuclear plant is safe from earthquakes: NRC

    Despite repeated assertions by Pacific Gas & Electric Co. that the Diablo Canyon nuclear plant is safe from earthquakes, the U.S. Nuclear Regulatory Commission (NRC) has ordered PG&E to provide more proof. Critics of the plant’s continuing operation say the order confirms concerns that faults surrounding Diablo Canyon are capable of more ground motion than the reactors were built to withstand and that the plant is in violation of its operating license and should be closed immediately.

  • Seismic safety of nuclear power plants in Scandinavia to improve

    Since the Fukushima accident, Nordic nuclear power plant areas have given greater priority to understanding the safety implications of seismic events. The Technical Research Center of Finland (VTT) and various Nordic players are co-developing new methods of making seismic hazard estimates of anticipated earthquakes in Fennoscandia — the region comprising the Scandinavian Peninsula, Finland, Karelia, and the Kola Peninsula in Russia.

  • Israel worries about its own Big One

    The magnitude 7.8 earthquake that struck Nepal, leaving more than 4,000 people dead, has alerted earthquake experts in Israel about the country’s own seismic risk, which could result in a large quake months or a few years from now. Israel, the Palestinian territories, and Jordan are sitting on a major fault line which constitutes “a real, as well as a current, threat to the safety, social integrity, and economic well-being of the people in the region,” reads a 2007 earthquake report.

  • Preventing a Fukushima-like disaster in Europe

    In 2005, Europe was exposed to a potential risk of a nuclear disaster caused by the flooding of the Loviisa nuclear power plant in Finland. Sea levels rose by 1.73 meter above normal levels, due to a storm. As a result, flood defenses have been reinforced. Floods are likely to occur more frequently than anticipated when nuclear power plants where built, due to climate change. Improved safety management and further collaboration between experts are required to minimize the risk of flooding at coastal nuclear plants in Europe.

  • France’s flagship nuclear power reactor hobbled by mishaps, delays

    France’s position as a leader in the nuclear energy industry is being undermined by the country’s pending flagship nuclear reactor, which may be delayed by another year following a series of setbacks. The third-generation European Pressurized Reactor (EPR), built by Areva and EDF, was meant to be in operation by 2012 and its designers claimed it would be one of the safest — built to resist the impact of a commercial airliner crash — and the most energy efficient reactors in the world. EPR was to represent France’s nuclear renaissance, a vision to replace the country’s aging nuclear plants over time. The renaissance, however, has faced several setbacks, mishaps, and delays.

  • U.S. says South Africa’s weapon-grade uranium not sufficiently secure

    In the early 1990s South Africa’s former apartheid government dismantled the country’s six nuclear bombs and its nuclear weapons-making infrastructure as it began planning the transformation of the country into a democracy. The nuclear fuel, extracted from the country’s nuclear weapons, has over time been used to make medical isotopes, but roughly 485 pounds remain. A November 2007 breach at the Pelindaba nuclear research center, where the nuclear fuel is stored in a former silver vault, alarmed U.S. officials, who had reason to believe the culprits were after the center’s fuel inventory. Incentives from the Obama administration for South Africa to convert its nuclear-weapons fuel, have been rejected by South Africa.

  • In South Africa, bomber of apartheid era nuclear power plant is a hero, not a terrorist

    In December 1982, Rodney Wilkinson planted four bombs that caused $519 million in damages at the Koeberg nuclear power plant north of Cape Town, South Africa. The attack, which many believe to be the most ambitious and successful terror attack against a nuclear facility, remains a symbol of African National Congress (ANC) war against South Africa’s then-apartheid government. The 1982 Koeberg assault, however, and a 2007 raidby two yet-to-be-identified armed groups on South Africa’s Pelindaba nuclear research site, are at the root of U.S. concerns about the safety of South Africa’s roughly 485 pounds stockpile of highly enriched uranium.

  • Critics: PG&E downplays quake risk to Diablo Canyon nuclear plant

    Since the Diablo Canyon nuclear power plant in California was opened by Pacific Gas and Electric Co. (PG&E) in 1985, geologists have discovered three fault lines nearby, which could threaten the plant. The three faults are capable of quakes even stronger than the one which ravaged the Napa Valley last year, and critics of PG&E say the company has been minimizing the risks the three faults pose. The company rejects the criticism. The critics are now suing to company to force it to reapply for an operating license – with the information about the three faults included in the application.

  • Scientists develop deep borehole disposal (DBD) method to deal with nuclear waste

    Technologies which will enable nuclear waste to be sealed five kilometers below the Earth’s surface could provide a safer, cheaper and more viable alternative for disposing of the U.K.’s high level nuclear waste. Scientists calculate that all of the U.K.’s high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes five kilometers deep, fitting within a site no larger than a football pitch. The concept — called deep borehole disposal — has been developed primarily in the United Kingdom, but is likely to see its first field trials in the United States next year.
