  • The Lesson of Procrustes

    Procrustes the metal worker—not to be confused with Krusty the Klown—was an important figure in Greek mythology. A son of Poseidon, Procrustes was an iron smith, thief, murderer, and inn keeper. He offered hospitality to strangers passing his place on the sacred byway between Athens and Eleusis. For a price.

  • ITER Gets New Life

    The International Thermonuclear Experimental Reactor (ITER) in southern France, the world’s biggest nuclear fusion research project, is seeing a revival. After a budget shortfall last year and cost projections that continue to escalate, in September, the project got the European Parliament’s (EP’s) backing for an autonomous budget that seeks to guarantee transparent and reliable financing while limiting cost overruns. Japan also announced that it would increase its budget for ITER by 50% (the current ITER director-general is Japanese). Also in September, scientists announced that after an 18-month shutdown to upgrade the Joint European Torus (JET)—the world’s largest magnetic fusion device—the machine is ready to test materials to be used inside ITER (Figure 5).

  • Condenser Tube Failure Mechanisms

    The operating environment within a condenser is extremely harsh, and in spite of the designer’s best intentions, sometimes tubes made of the best materials fail. The most important tube failure mechanisms typically result from different forms of corrosion and erosion. When it’s time to select new condenser tube material, you’ll need to consider the projected operating environment and failure mechanisms that material will be subjected to.

  • Public Power Challenges Moody’s Proposed New Metrics

    Public power utilities depend upon access to capital at favorable rates. So the munis pay special attention when Wall Street rating agencies talk about tinkering with how they establish bond ratings for municipal utility projects. Thus, recent moves by Moody’s Investors Service has drawn some fire from public power.

  • THE BIG PICTURE: Reactors Under Construction

    For seven years in a row, the number of new nuclear construction starts increased markedly. Then the accident at Japan’s Fukushima Daiichi plant occurred, prompting shutdowns of existing plants and a rethinking of future plans in many countries. Nevertheless, the International Atomic Energy Agency (IAEA) expects “continuous and significant growth” in the use of nuclear […]

  • Condenser Retubing

    Once the condenser tubes are designed, selected, and purchased, the final step in a retubing project is to remove the old tubes and install the new ones. The success of this project is very dependent upon attending to quality control, following proper procedures, using the right tools, and having a highly skilled workforce.

  • Improving Condenser O&M Practices

    Losses attributed to condenser tube leaks, fouling, and failures continue to climb, costing the power generation industry an estimated half-billion dollars annually in maintenance costs and loss of production. Investing in an effective condenser maintenance program will reduce those expenses in short order.

  • Solar Power’s Elephant in the Living Room

    Understanding the reliability and failure mechanisms of photovoltaic modules is crucial to understanding how well they will perform over time. But today there are no test standards in place to judge this crucial issue.

  • Steam Turbine Cleaning Using Chemical Foams

    In the May issue, we discussed the importance of either preventing copper plating of the high-pressure (HP) steam turbine rotor or finding a good foam or mechanical removal means of restoring lost efficiency. In that article we noted that “copper deposits typically form on the stationary nozzle block or first-stage stationary blades” and that those deposits usually result in a steam turbine loss of capacity at a rate of about 2 to 3 MW per month. We also stated that the “general rule of thumb is that there is a reduction of about 1 MW of generating capacity for each 1 to 2 pounds of deposit that accumulates on the HP turbine.

  • Nordic Nations Provide Clean Energy Leadership

    In the past few years, nuclear concerns, rising oil prices, and a growing understanding of our environmental impact has given energy issues a higher profile worldwide.

  • Legal Issues That Float in the Cloud

    Cloud computing is a growing phenomenon for many businesses, large and small, promising significant efficiencies and cost savings. But, as with anything new, computing in the cloud poses some unforeseen legal issues.

  • Predictive Maintenance That Works

    This is the fourth in a series of predictive maintenance (PdM) articles that began in the April “Focus on O&M” with an introduction to PdM as a process whereby maintenance is performed based on the condition of the equipment rather than on a predetermined interval. In the May and July issues, we began exploring specific PdM techniques, such as motor-current signature analysis and oil analysis.

  • Crossing the Digital Divide

    One of the great successes of the power generation industry over the past two decades has been the significant increase in nuclear plant reliability and other performance standards. However, there is reason to be concerned that the design, operation, and maintenance practices used by the current fleet of plants do not leverage all the possible advantages from a digital controls upgrade. Perhaps past success is the biggest barrier to future success.

  • Final FERC Rule Backs Reasonable Rates for Frequency Regulation Service Providers

    A new rule enacted by the Federal Energy Regulatory Commission (FERC) on Thursday orders organized wholesale power market operators to pay “just and reasonable rates” for providers of regulation service, an ancillary transmission service that protects the grid by correcting deviations in grid frequency and balance on transmission lines with neighboring systems.

  • Alberta Court Rejects Environmental Group’s Challenge to Planned Coal Plant

    An Alberta court on Friday rejected an environmental group’s challenge to the August-issued Alberta Utility Commission approval of a planned 500-MW supercritical coal-fired addition at the 150-MW H.R. Milner Generating Station in the Grande Cache area. The court’s decision paves the way for Maxim Power to begin construction of the controversial unit—the first coal plant built in the province in a decade.

  • California Adopts Final Cap-and-Trade Regulation

    After three years of development, dozens of public workshops, and hundreds of meetings with stakeholders, the California Air Resources Board (ARB) on Thursday adopted a final rule to cap California’s greenhouse gas emissions and put a price on carbon. The cap-and-trade program starts in 2013 for electric utilities and large industrial facilities.

The $60 million investment is part of the DOE’s SunShot Initiative, a collaborative effort to reduce the cost of solar energy 75% and make it cost competitive with other forms of energy by the end of the decade.

  • Companion Coal Ash Bill Introduced in Senate

    A companion bill to the U.S. House’s recently passed Coal Residuals Reuse and Management Act (H.R. 2273) was last week introduced in the Senate by Sens. John Hoeven (R-N.D.) and Kent Conrad (D-N.D.).

  • House Passes Bill to Delay, Limit Boiler MACT Rules

    The U.S. House of Representatives on Thursday passed The Environmental Protection Agency (EPA) Regulatory Relief Act of 2011 (H.R. 2250) by a vote of 275-42 .The bill, which seeks to limit the federal agency’s rules limiting toxic air pollutants from commercial and industrial boilers and thwart the EPA from proposing a new standard for at least 15 months after enactment, now heads to the Senate, where it is unlikely to pass, industry analysts say.

  • House Votes to Leave Coal Ash Management to States, Not EPA

    On Friday, following passage of a bill to delay Environmental Protection Agency (EPA)–promulgated Boiler MACT rules, the U.S. House of Representatives also passed the Coal Residuals Reuse and Management Act (H.R. 2273), legislation that would impede the federal agency from proceeding with its May 2010 proposed rule to regulate coal ash residuals.

  • European Transmission Operators Warn of Possible Load Shedding This Winter

    An association of 41 European transmission system operators (TSOs) from 34 countries last week warned that adequacy margins in the coming winter could dip dangerously and threaten power supply for most of the continent.

  • U.S. Solar Panel Makers Petition Govt. to Investigate Chinese Solar Subsidies, Dumping

    A coalition of seven U.S. manufacturers of solar cells and panels today petitioned the U.S. International Trade Commission (ITC) to investigate whether Chinese manufacturers are illegally dumping crystalline silicon solar cells into the U.S. market and receiving illegal subsidies from China. The measure follows a string of bankruptcy filings by several U.S. solar manufacturers in the past few months.
