By Kennedy Maize Washington, D.C., Nov. 5, 2010 – It could be a sign of the times, or merely a temporal coincidence. Liza Heinzerling this week announced she is leaving the Environmental Protection Agency, where she has been a hard-charging policy chief, to return to teaching at the Georgetown University law school. The departure came […]

By Kennedy Maize Washington, D.C., Nov. 4, 2010 — Here’s another major blow to the increasingly problematic nuclear renaissance: France’s “European Pressurized Water” (EPR) reactor design is “in crisis,” according to a new analysis by a British economist  and nuclear energy policy analyst. The problems with the “Generation III+” reactor are so serious that they […]

On Tuesday, while voters rejected many politicians who supported cap-and-trade legislation, the New Mexico Environmental Improvement Board (EIB) adopted what it said are the most comprehensive greenhouse gas regulations in the U.S.

Days after California’s Air Resources Board (ARB) released its proposed greenhouse gas cap-and-trade regulation, voters on Tuesday rejected a controversial proposition to suspend the state’s landmark greenhouse gas reduction law.

A set of common standards proposed by European Union (EU) Energy Commissioner Guenther Oettinger today could force utilities in the 27-nation bloc to abide by binding rules for the long-term storage of nuclear waste. The proposal chiefly calls for construction of long-term deep geologic storage repositories.

A U.S. district court judge last week ordered Southwestern Electric Power Co. (SWEPCO) to cease work on a small tract of land designated as jurisdictional wetlands where the utility is building the $1.7 billion John W. Turk., Jr. power plant—the nation’s first ultrasupercritical pulverized coal power plant.

Nuclear plant enriched uranium supplier USEC on Tuesday said it was in discussions with the Department of Energy’s (DOE’s) Loan Guarantee Program office to proceed to the next step toward obtaining a $2 billion conditional loan guarantee commitment for its American Centrifuge Plant (ACP).

The STP Nuclear Operating Co. declared an "Unusual Event" at 10:38 a.m. this morning when a circuit breaker malfunctioned, which caused Unit 2 to go offline.

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.

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.

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.

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.”

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?

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 […]

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.

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.

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 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.

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.

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?

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 […]

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.

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 […]

Engineers and technicians searching for a high-performance oxidation-reduction potential (ORP) sensing solution will find that the S10 and S17 ORP Sensors from Electro-Chemical Devices (ECD) feature a no-glass design with platinum or gold sensor tips to operate safely in a wide range of applications. ECD’s ORP S10 and S17 Sensors come with easily replaceable ORP […]

Business planning that doesn’t carefully consider workforce issues can result in economic and management headaches.

Atomstroyexport, the Russian Federation’s nuclear power equipment and services export monopoly, in September signed a US$1.8 billion contract with the Chinese government for development of the second stage of the Tianwan nuclear power plant in Lianyungang City. Under the agreement, Units 3 and 4 are to be built in a way similar to construction of the first stage of Tianwan—two Russian-designed VVER-1000 reactors that came online in 2007, each with a rated capacity of 1,060 MW.

The University of California, San Diego has been accumulating awards for its savvy use of a constellation of power generation and energy-saving technologies. The campus already controls a fully functioning microgrid—including a cogeneration plant—and, as befits a research institution, is constantly looking for new ways to make its energy system smarter. This “living laboratory,” as campus leaders like to call it, demonstrates what it takes to build a smarter grid and why the effort is worth it.

The new QC#1 MT Pre-Cleaner from Martin Engineering is a high-quality cleaning blade for use on vulcanized conveyor belts. It features a special polyurethane blend and tungsten carbide tip to deliver service life two to three times longer than conventional urethane blades, the company claims. Designed to provide excellent cleaning performance without any break-in period, […]

The smart grid, a truly disruptive business force, will require a new regulatory paradigm and new approaches to the electric utility business model.
