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 […]

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.

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.

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.

The first unit of Ling Ao phase II (Unit 3) in Guangdong Province, China, entered commercial operation in late September. The 1,080-MW reactor is the first CPR-1000—a Chinese design—to be built, and its start-up marks a major milestone in the country’s concerted nuclear power expansion.

Microturbine technology has evolved from early systems of 30 kW to 70 kW to today’s systems, which can have individual ratings of 200 kW to 250 kW. Packages up to 1 MW are now available that can be assembled into multipac units for projects of 5 MW to 10 MW. These modern units are packaged with integrated digital protection, synchronization, and controls; they produce high combined heat and power efficiencies; and they are capable of using multiple fuels.

Correction In the September issue’s “Taming Condenser Tube Leaks, Part I,” the first full paragraph in the main text on page 57 should say, “If chloride and sulfate in the steam cannot be maintained below 8 ppb….” POWER regrets the error.

The Scottish poet Robert Burns had it right. Using the power to see ourselves as we really are, and as others see us, is a key to leadership in business.

Swedish company Vattenfall in late September officially opened the 300-MW Thanet Offshore Wind Farm in southeast England. Covering an area of 35 square kilometers, the installation comprising 100 Vestas V90 turbines, each 115 meters (m) high, is the largest offshore wind farm in the world to date.

Presenters at the inaugural GridWise Global Forum in Washington, D.C., September 21 to 23 had a lot to say about the prospects for smarter grids. This synopsis of facts and opinions shared at the event, which attracted several smart grid A-listers, looks at the major challenges ahead, especially for the U.S.

Sometimes we do things for the wrong reason . . . that turns out to be exactly right.

The pilot-scale project at Georgia Power’s Plant Yates near Newnan, Ga.—the first step in one of the industry’s largest demonstrations of a start-to-finish coal-fired power plant carbon capture and storage system—reached a significant milestone this September, capturing the greenhouse gas for the first time.

Turkey, a country that has long vied to become part of the European Union, is finally part of its grid, at least. The nation’s power system was synchronized with Continental Europe’s interconnected grid this September, marking the beginning of a year-long trial period in which security and performance will be monitored.

In August, researchers from the University of Cincinnati who are working on creating an artificial foam that could absorb carbon dioxide (CO₂) from the flue gas at power plants and convert it into biofuel won the grand prize at the 2010 Earth Awards in London.

TVA’s 550-MW Combined-Cycle Plant Starts Operations. The Tennessee Valley Authority (TVA) on Sept. 30 officially began operating the Lagoon Creek Combined Cycle Plant, a 550-MW natural gas–fired plant, near Brownsville, Tenn. The federal utility said that the new plant, the first new power generation source built by TVA since 2002, would provide power during days […]

The U.S. Nuclear Regulatory Commission (NRC) approved an updated “waste confidence” rule in mid-September that reflects the agency’s confidence that spent nuclear fuel (SNF) can be safely stored for at least 60 years beyond the closing date of any U.S. nuclear plant. Approval of this rule was required before the NRC can license any new reactors that will be required to store SNF on site indefinitely.

EPRI recently issued a handbook on nuclear spent fuel storage that examines regulatory trends affecting used fuel storage, describes available dry storage technologies, reviews planning considerations for spent fuel storage installations, and discusses technical issues affecting dry storage.

The Chemical Safety Board (CSB)—an independent federal agency charged with investigating serious chemical accidents such as equipment failure, as well as inadequacies in regulations, industry standards, and safety management systems—recently released multiple reports that should be made part of every power plant’s safety training program.
