  • NRC Panel Deals Final Blow to Comanche Peak Expansion’s Opponents

    The Nuclear Regulatory Commission’s (NRC’s) Atomic Safety and Licensing Board panel dismissed the last objection filed by anti-nuclear groups and a Texas lawmaker to block expansion of Luminant Energy’s Comanche Peak nuclear plant.

  • Judge Orders Immediate Suspension of 11.2-GW Brazilian Hydro Project

    A federal judge in Brazil on Friday ordered immediate suspension of a license permitting construction of the controversial 11,233-MW Belo Monte dam complex. The license was recently issued by Brazil’s environmental agency, IBAMA, and it would have allowed dam-building consortium Norte Energia to begin clearing forestland on the margins of the Amazon’s Xingu River.

  • DOE Grants First Geothermal Loan Guarantee

    The U.S. Department of Energy on Thursday finalized a $96.8 million Recovery Act–supported loan guarantee to Neal Hot Springs, a project sponsored by U.S. Geothermal, to construct a 23-MW geothermal project in Oregon’s Malheur County.

  • Small Nuclear Reactor Concept Goes Underwater

    France in January announced its contribution to the wave of small and modular reactors (SMRs): a submarine-like nuclear plant that can be submerged in waters 60 meters (m) to 100 m deep and several kilometers offshore.

  • Proper Sizing of Steam Header Drains Prevents Water Induction

    Steam turbines convert the thermal energy in motive steam to rotating mechanical energy, and the generator converts that energy into electrical power. One important requirement for safe and reliable operation is preventing water induction in the steam turbine and avoiding water hammer in the steam piping system. ASME standards present the design guidelines for removing moisture from steam lines; this article explains a practical design process.

  • Brazil Greenlights 11-GW Belo Monte Project

    Brazil’s environment agency, IBAMA, in January issued a partial installation license that allows for construction of the controversial Belo Monte dam complex, an 11,233-MW project estimated to cost some 19.6 billion reals (US$11.7 billion), to begin on the margins of the Amazon’s Xingu River. Saying the project is needed to meet soaring electricity demand when completed, as planned in 2015, the government gave license to dam-building consortium Norte Energia to begin clearing 238.1 hectares (588 acres) of forestland.

  • European Offshore Wind Turbine Capacity Grows 51% in 2010

    Europe installed 308 new offshore wind turbines in 2010—a 51% increase in installed offshore capacity over the previous year, the European Wind Energy Association (EWEA) said in new figures released this January. The 883 MW of new capacity—worth some €2.6 billion—were installed at nine wind farms in five countries, bringing the continent’s total offshore installed wind capacity to 2,964 MW.

  • Energy, GDP, and Thomas Malthus

    A new article in Bioscience looks again at the connection between economic growth and energy demand, shedding little light on the subject and further demonstrating the limits of neo-Malthusianism. Of course there is a relationship between energy and economic growth, but what is it? No answers here; only a doomsday prediction.

  • E.ON Starts 417-MW Cogeneration Plant in Slovakia

    At the beginning of 2011, German firm E.ON began operation of its new 417-MW Malzenice gas and steam turbine power station in Slovakia’s Trnava region, near the country’s capital, Bratislava (Figure 5). The facility, which is expected to generate more than 300 billion kWh annually, boasts an efficiency of 58%—which E.ON claims is among the “highest in Europe.”

  • TREND: Uranium Business Heats Up

    The long-struggling uranium business, hoping that demand for nuclear fuel will increase, is slowly stretching its muscles and strengthening exploration and production efforts in the U.S. and elsewhere.
