  • NRC Commissioners Grilled on Nuclear Rules, Security, and Efficiency

    “It’s as if the government—the [Environmental Protection Agency (EPA)] and the [Nuclear Regulatory Commission (NRC)]—is trying to regulate the nuclear energy industry out of business, just like it’s been trying to regulate fossil fuels out of business,” said Sen. Jim Inhofe (R-Okla.), during the U.S. Senate Committee on Environment and Public Works’ eighth NRC oversight […]

  • EPA Reports Toxic Air Releases Down Due in Part to Coal Plants

    The Environmental Protection Agency (EPA) reported on Feb. 4 that total releases of toxic chemicals decreased 12%, while toxic air releases were down 8% in its annual Toxics Release Inventory (TRI) report. The data—from 2012—was compiled from 21,024 facilities that are required to report to TRI. Of that total, only 582 of the facilities fall […]

  • Safety and Oil & Gas Boom Focus of N.D. Generation Conference

    The 35th Annual Energy Generation Conference (EGC) held in Bismarck, N.D., Jan. 28–30, highlighted the importance of North Dakota to national discussions of energy policy. The opening session focused on the oil and natural gas boom currently taking place in the state. The Bakken shale play is expected to produce over one million barrels of […]

  • Idling of Two Coal-Fired Plants Will Cost Jobs

    Big Rivers Electric Corp.—a member-owned, not-for-profit, generation and transmission cooperative serving western Kentucky—plans to idle two of its coal-fired power plants following the loss of its largest industrial load. The D.B. Wilson Station, a 417-MW plant located in Centertown, Ky., will idle on Feb. 1, barring a miracle. Big Rivers simply doesn’t need the power […]

  • The Coal to Gas Exodus Continues

    Alabama Power Co., a subsidiary of Southern Co., has applied for air permits that would authorize the company to retrofit four coal-fired electric generating units, enabling them to add the capability to burn natural gas as a primary fuel. The Alabama Department of Environmental Management gave public notice of the application on Jan. 8. The […]

  • Safety Culture Scrutinized at U.S. Nuclear Plant

    Officials from Wolf Creek Generating Station, a 1,200-MW nuclear plant located northeast of Burlington, Kan., met with the Nuclear Regulatory Commission (NRC) on Jan. 22 to review actions the company has taken in response to the NRC’s issuance of a chilling effects letter on Aug. 19, 2013. The NRC defines a “chilled work environment” as […]

  • Former Nuclear Plant Supervisor Sentenced for Falsifying Records

    A former chemistry manager at a nuclear power facility was fined $500 and sentenced to 18 months’ probation on Jan. 16 for engaging in deliberate misconduct in connection with a matter regulated by the Nuclear Regulatory Commission (NRC). Daniel Wilson pleaded guilty to felony charges of fabricating chemical test results regarding diesel fuel used to […]

  • Will the Nuclear Industry Bite on Indiana’s Bait?

    A new bill authored by state Sen. James Merritt, R-Indianapolis, is designed to promote nuclear power development in Indiana, which doesn’t currently have any operating nuclear power plants. Senate Bill 302 provides that projects involving the construction of nuclear energy production or generating facilities qualify for the financial incentives available for clean energy projects. Current […]

  • Nuclear Revival in the UK—Should the U.S. Take Notice?

    With 16 reactors providing roughly 18% of the UK’s electricity needs, nuclear power is a vital part of the country’s energy supply. The trouble is that all but one of the aging reactors is expected to be permanently shutdown within the next 12 years. Recent developments, however, indicate that there is no reason for the […]

  • How Stealth Combustion Losses Lower Plant Efficiency. Part 2: The Solutions

    Important process variables that affect unit efficiency were reviewed in Part 1 of this two-part report. Many of those process parameters were also identified as related to boiler air in-leakage.  These stealthy combustion losses are difficult to identify or locate yet have a significant effect on boiler combustion efficiency. Keeping your plant operating at or near […]
