  • NFPA Gas Purging Rules Updated

    The CSB has made urgent recommendations to the NFPA and the International Code Council to prohibit indoor purging and require companies and installers to purge flammable fuel gases to safe locations outdoors, away from workers and ignition sources.

  • Benchmarking Nuclear Plant Capital Requirements

    The EUCG Nuclear Committee’s primary goal is to optimize the costs and reliability performance of participating plants by publishing for its members a comprehensive database of performance metrics and best practices derived through surveys of its membership. Earlier reports examined staffing and performance data. In this exclusive EUCG report, we examine nuclear plant capital requirements.

  • Matching Load and Generation at UCSD

    “Smart Power Generation at UCSD” explains how the University of California, San Diego (UCSD) is maximizing the value of combined heat and power. However, like any other grid-controlling entity large or small, the campus has to match generation and load. Its two Solar Turbines gas turbines operate in baseload mode 24/7 while the cogeneration side of the plant maximizes the value of “waste” heat and electricity that isn’t needed to serve immediate load by generating steam and chilled water for campus heating and cooling.

  • TREND: Smart Grid Complications

    Despite a trendy moniker and lots of hype and interest, the smart grid has been facing some major setbacks of late, as regulators and customers begin challenging some of the claims for what interconnected smart meters will deliver in the way of tangible benefits.

  • Abrasion-Resistant Pipe Handles Ash Slurry

    Steel piping systems are widely used at coal-fired power plants for a variety of purposes, including the conveying of coal ash slurry to nearby settling ponds, the transfer of limestone slurry to absorber spray towers for removal of SO2 and dilute hydrochloric acid from flue gases, and for transporting away the calcium sulfate by-product of the flue gas desulfurization process.

  • The Best of U.S. Nuclear Developments 2010: Uprates and Loan Guarantees

    Utilities are spending billions of dollars on nuclear plant uprate projects, and Southern Company has been offered $8.3 billion in federal loan guarantees to build Vogtle Units 3 and 4 (although the final deal has yet to be signed). Meanwhile, other nuclear developers have slashed preconstruction spending as the cost of the “nuclear renaissance” becomes evident.

  • Combined Heat and Power Across the U.S.

    The University of California, San Diego (see “Smart Power Generation at UCSD”) is just one of many combined heat and power (CHP), or cogeneration, systems in the U.S. A 2008 report by Oak Ridge National Laboratory (ORNL), “Combined Heat and Power: Effective Energy Solutions for a Sustainable Future,” notes that Texas has the most CHP capacity—much of it used by the petrochemical and petroleum refining industries. California ranks second, largely a result of “industrial demands, stringent air quality requirements, and effective policies that encourage adoption of CHP.”

  • Uranium Enrichment: Boom or Bust?

    The prospects of a worldwide nuclear power renaissance have spawned many plans for increasing uranium enrichment capacity. Could those plans swamp the world in SWUs?

  • Air Casters Speed Equipment Moves

    When it comes to moving megaton items like feedwater heaters or recirculating pumps, conventional moving tools such as wheel rollers, cranes, hoists, and come-alongs may be virtually useless. In some cases, moving large components is dangerous in a space-constrained location surrounded by delicate process control equipment. Feedwater heater and recirculating pump removal and replacement are […]

  • Retrofitting BWR Recirculation Pumps with Adjustable-Speed Drives

    Exelon Nuclear recently replaced the original motor-generator sets for its boiling water reactor (BWR) recirculation pumps at its Quad Cities Generating Station Unit 1 with adjustable-speed drives. We examine the actual energy savings, motor-starting characteristics, control accuracy and stability, and motor and cable thermal behavior of this retrofit project.

  • NRC Chairman Floats Plan for Long-Term Spent Fuel Storage

    A sea change in thinking about how to deal with spent nuclear fuel in the U.S. appears to be on the policy and political horizon, rekindling battles last fought in the 1980s about how to pay for the disposal of nuclear waste and where to put it. Holes in the ground look increasingly unlikely.

  • EPA’s Mercury Rule: Another Incarnation Coming

    Much like the shape-shifting substance it regulates, the mercurial enforcement rule that governs mercury emissions from coal-fired power plants has changed unpredictably several times in recent years.

  • Biomass Power Under Attack

    Biomass energy has been an up-and-down industry for decades. As public awareness grows, it inevitably influences new tax legislation and environmental regulations. Two recent events have made the climate for development of this renewable resource even more volatile.

  • Dodd-Frank: Legislation and Magical Misdirection

    Here’s how, with almost no attention, recent financial reform legislation changes how business must deal with whistleblower employees and affects other seemingly nongermane issues.

  • Collaborative Team Investigates Long-Term Nuclear Operations

    The Atomic Energy Act originally established the length of a U.S. commercial nuclear reactor license as 40 years and made it renewable for another 20 years. The U.S. Nuclear Regulatory Commission has stated that it bases the length of these licenses (and the 50+ renewed licenses granted to date) not on any particular technical limitation but on whether the plant meets current safety requirements. Does this mean there could be reactor life after 60?

  • Semi-Automated Tube Bundle Cleaner

    Part of a family of automated and semi-automated tube-cleaning accessories, the new Saflex 2000 makes tube bundle cleaning more productive because it can clean four times as many tubes in a given period as manual water jetting, says NLB Corp. Operating at pressures up to 40,000 psi, the semi-automated accessory cleans two tubes (ranging from […]

  • Social Media: Watch Your Words and Fingers

    Letting loose on Facebook, Twitter, and email, no matter how tempting and satisfying, can be a prescription for big trouble for you and your organization. Watch out for the dangers of social media on the job.

  • Follow the Leader

    Another year has passed and the promised U.S. nuclear renaissance is still in the Dark Ages. Blame for slow progress is usually cast on the pedestrian pace of finalizing loan guarantees, the economy and slow load growth, or the rising cost of construction. The excuses end when competition increases. Two years have elapsed since the […]
