    Omaha Public Power District (OPPD) has postponed restart of its troubled 478-MW Fort Calhoun nuclear plant for the third time since it was shut down 16 months ago. Restart of the reactor, located 19 miles north of Omaha, Neb., requires regulatory approval, and that is now tentatively anticipated early next year.

  • Federal Court Holds TVA Liable for Kingston Coal Ash Spill

    A federal district court on Thursday ruled in favor of more than 800 plaintiffs when it held the Tennessee Valley Authority (TVA) liable for the December 2008 failure of coal ash containment dikes at its Kingston Fossil plant in Roane County, Tenn., that resulted in the spill of more than a billion gallons of coal ash sludge.

  • Carbon Dioxide Injection Begins at Fully Integrated Coal-Fired CCS Project

    Injection of carbon dioxide began last week at one of the world’s first fully integrated coal-fired carbon capture, transportation, and geologic storage projects. The "Anthropogenic Test" conducted by the Southeast Regional Carbon Sequestration Partnership (SECARB) transports carbon dioxide via a 12-mile pipeline from a 25-MW post-combustion carbon capture facility at Southern Co.’s 2,657-MW Plant Barry in Bucks, Ala., and sequesters it within a saline Paluxy Formation at the nearby Citronelle Oil Field operated by Denbury Resources.

  • Exelon Withdraws Early Site Permit Application for Victoria County Reactor

    Exelon on Tuesday said it plans to withdraw its Early Site Permit (ESP) application for construction of a new reactor at an 11,500-acre tract of land southeast of Victoria, Texas, saying “low natural gas prices and economic and market conditions . . . have made construction of new merchant nuclear power plants in competitive markets uneconomical now and for the foreseeable future.”

  • Trade Representatives Request Investigation on U.S. Renewables in Global Context

    The U.S. Trade Representative on Monday asked the U.S. International Trade Commission (ITC) to investigate how U.S.-provided renewable energy services affect development of renewable energy projects worldwide.

  • Report: Implementing Federal Dry Storage Program by 2020 Is Nation’s Best Waste Storage Option

    Implementation of a new federal nuclear spent fuel–handling program starting in 2020 to remove 6,000 metric tons of uranium (MTU) per year for 10 years and 3,000 MTU per year thereafter could allow for full decommissioning of U.S. sites awaiting fuel removal. It would also enable retirement of all private Independent Spent Fuel Storage Installations by 2030, and achieve approximately a 10% reduction in average wet pool density, a new study from consulting firm The Brattle Group suggests.

  • Warm Water, Repairs, and a “Dropped” Control Rod Separately Prompt Reactor Shutdowns

    As warmer-than-average waters in Connecticut’s Long Island Sound last week prompted Dominion to shut down one unit at its Millstone Nuclear Plant, an ammonia release caused an evacuation of part of Tennessee Valley Authority’s Watts Bar Unit 1, and Constellation Energy shut down of its Calvert Cliffs Unit 1 reactor after a control rod unexpectedly dropped into the reactor’s core. Then, on Tuesday, Xcel Energy shut down its Monticello Nuclear Generating Plant and Unit 1 of its Prairie Island Nuclear Generating Plant for repairs.
