  • Brexit Implications for UK Nuclear Power

    When the UK, the European Union’s (EU’s) second-largest economy, voted to leave the union on June 23, reactions were swift and sometimes unexpected, but what does the Brexit vote mean for the nuclear power industry, which is an increasingly global one? Based on comments made at this week’s World Nuclear Exhibition (WNE) outside Paris, the […]

  • California Governor, Legislature, Agree on Major Overhaul of CPUC

    California Gov. Jerry Brown and members of the California legislature have agreed on a package of “sweeping” reforms designed to overhaul the California Public Utilities Commission (CPUC), increase transparency, and change how the CPUC conducts much of its business. The changes come in the wake of repeated disclosures of illegal ex parte meetings and communications […]

  • World Nuclear Exhibition Addresses Challenging Markets and New Solutions

    The second World Nuclear Exhibition (WNE) began on June 28 in Le Bourget, just outside Paris, with the usual mixed messages about the need for and challenges of nuclear power globally.

  • U.S. Nuclear Power Plant Closures [Slideshow]

    According to the U.S. Energy Information Administration, nuclear power has accounted for about 20% of electricity generated in the U.S. each year since 1990. In fact, the U.S. nuclear fleet out produced France—the country with the next highest nuclear generation—by more than two to one in 2012. Russia was a distant third, generating less than […]

  • District Energy Systems Improve Efficiency and Reduce Carbon Emissions

    Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

  • PG&E Moves to Retire 2.3-GW Diablo Canyon Nuclear Plant

    Diablo Canyon, the two-reactor nuclear power plant on the central California coastline, will be permanently shuttered by 2025 under a renewables-boosting initiative announced today by its owner, Pacific Gas and Electric (PG&E). The company on June 21 unveiled a “joint proposal” with labor and environmental groups that seeks to increase investment in energy efficiency, energy […]

  • The Importance of RTO Maintenance

    The importance of RTO maintenance
    RTOs or Regenerative Thermal Oxidizers control emissions without producing harmful byproducts or hazardous waste. They help destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other odorous emissions created during normal manufacturing and industrial processes by combusting them into carbon dioxide and water. RTOs pass hot exhaust gas and cooler

  • Fort Calhoun Nuclear Power Plant to Close by Year-end

    The Omaha Public Power District (OPPD) board of directors voted unanimously on June 16 to close Fort Calhoun Station, the smallest nuclear power plant in the U.S., due to economic reasons. In April, OPPD Board Chairman Mick Mines asked senior management to develop potential scenarios regarding future power resources. Tim Burke, president and CEO of […]

  • Experts: Gas Power’s Expansion Riddled with Roadblocks

      Even though it may dominate forecasts, natural gas–fired generation faces a troubled expansion in the U.S., according to experts from a variety of stake-holding entities—including an industry group, a utility, a generator, and a pipeline company. Challenges that have few solutions—from price volatility, to gas transport concerns, to rule uncertainty—may upend the nation’s dependence […]

The plan sets […]

  • GE-Hitachi Exits Nuclear Laser-Based Enrichment Venture

    GE-Hitachi Nuclear Energy is pulling out of Global Laser Enrichment (GLE), a company that in 2012 got the Nuclear Regulatory Commission’s (NRC’s) unprecedented approval to build and operate a full-scale laser uranium enrichment facility. The move was precipitated by a change in business priorities, but it doesn’t necessarily mean the GLE’s proprietary SILEX technology is […]

  • Is There a Market for Small Modular Reactors?

    The nuclear industry has been expecting big things from small modular reactors (SMRs) for a long time, but to date, no SMRs have reached commercial construction phase. That may change soon.

  • Two Exelon Nuclear Plants Fail to Clear PJM Auction

    Exelon’s Quad Cities and Three Mile Island nuclear plants have failed to clear the PJM capacity auction for the 2019–2020 planning year, and the future looks grim for at least one of those plants. The Chicago-headquartered company on May 25 confirmed that the two plants would not receive capacity revenue for the period. It also […]

  • Watts Bar Unit 2 Reactor Goes Critical (and That’s a Good Thing)

    The Tennessee Valley Authority’s (TVA’s) newest nuclear plant, Watts Bar Unit 2, achieved initial criticality on May 23 at 2:16 a.m. Although that may sound ominous to anyone untrained in nuclear terminology, initial criticality simply means that Watts Bar Unit 2 reached a state in which the reactor’s neutron population remained steady from one generation […]

  • Moniz: Incentives Needed to Alleviate Nuclear Power Woes

    U.S. Secretary of Energy Ernest Moniz said the time will come—perhaps 10 to 15 years from now—when “nuclear power is going to have to see a substantial resurgence.” Moniz was speaking on May 19 at the “Summit on Improving the Economics of America’s Nuclear Power Plants.” He provided opening remarks, framing the challenges facing the […]
