Washington, D.C., 6 August 2012 — It’s been a rough road for nuclear advocates in the U.S. of late, although nothing seems to dent the Pollyanna armor of the nuclear crowd, always appearing to believe a revival is just over the horizon and headed into view. Here are a few fraught developments for the nuclear […]

Back-to-back transmission grid failures in India plunged nearly 670 million people—roughly 10% of the world’s population—into darkness on Monday and Tuesday, paralyzing transport networks and crippling the country’s economic ambitions. Larger than both the August 2003 North American blackout and the March 1999 southern Brazil blackout, the unprecedented Indian grid failures are among the world’s worst.

A new report by the Government Accountability Office (GAO) finds that the Environmental Protection Agency (EPA) lacks centralized information on New Source Review (NSR) permits typically issued to fossil fuel-fired power plants by states, though the agency has spearheaded enforcement efforts for noncompliance. The report, which concedes that the NSR permitting process is “complex and controversial,” also suggests that a "substantial number" of existing generating units may not have complied with requirements to obtain NSR permits.

The Nuclear Regulatory Commission (NRC) last week issued a bulletin to all holders of nuclear plant operating licenses in the U.S., alerting them to a potential design vulnerability discovered at Exelon’s Byron Nuclear Generating Station in January that it says "could have damaged the plant’s emergency core cooling system."

Progress Energy Carolinas, which recently became a Duke Energy subsidiary, on Friday said it would accelerate the retirement of its 316-MW Cape Fear coal-fired plant, located near Moncure, N.C., and the 177-MW H.B. Robinson Unit 1 coal-fired plant, located near Hartsville, S.C., due to “pending changes in the environmental regulations and other rising costs for smaller, older technology plants.”

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on June 26 unanimously rejected all pending legal challenges against the U.S. Environmental Protection Agency’s (EPA’s) interpretation of the Clean Air Act (CAA) that allows the agency to regulate greenhouse gases (GHGs). What is the EPA’s future strategy in its war on coal?

The U.S. Environmental Protection Agency (EPA) has a long history of making waves with the electric power industry because of its efforts to regulate the way thermal power plants construct and operate their cooling water intake structures (CWIS). These structures divert billions of gallons of water into power plants’ cooling systems and can injure or kill billions of aquatic organisms.

AES Gener recently completed construction of twin coal-fired, 260-MW units in the electricity-starved desert of northern Chile that may serve as models for future hybrid-fossil plant designs. For meeting an aggressive construction schedule, integrating a 20-MW battery energy storage system, embracing desalination, using the first-of-its-kind seawater cooling tower in South America, and employing innovative financing methods, the AES Gener Angamos plant has earned POWER’s 2012 Plant of the Year Award.

Solid oxide fuel cells (SOFCs), which oxidize a fuel to produce electricity, have received much attention of late for the technology’s myriad benefits, including high efficiency, long-term stability, fuel flexibility, and low carbon emissions—all at a relatively low cost.

Combined Solar Technologies (CST) has designed, built, owns, and operates a water purification system located at the Musco Family Olive Co. facility in Tracy, Calif., that burns olive pits to purify highly saline wastewater through a distillation process while also producing electric power. For its pioneering approach, CST is the winner of POWER’s 2012 Marmaduke Award for excellence in plant problem-solving. The award is named for Marmaduke Surfaceblow, the fictional marine engineer and plant troubleshooter par excellence, whose exploits were chronicled in POWER beginning in 1948.

Siemens Energy in June announced it had produced the first batch of its new B75 Quantum wind turbine rotor blades, fiberglass components 75 meters (m) in length that were cast in one piece (Figure 3). The blades were manufactured to be installed this fall on Siemens’ second prototype of the German firm’s SWT-6.0 6-MW offshore […]

“If you build it, they will come” has proven a risky strategy for some smart grid projects. One of California’s largest investor-owned utilities faced the opposite challenge—customers whose behaviors necessitated a smarter grid. Customer involvement in and support for smart grid plans is a major reason SDG&E’s smart grid efforts continue to garner accolades, including the 2012 POWER Smart Grid Award.

Albania this June inaugurated its first major hydropower project since the early 1980s, bringing online Ashta I, the first of two run-of-river plants with a combined capacity of 53 MW. At the inauguration ceremony, Albania’s Prime Minister Sali Berisha called the plant “a novelty” because it is the largest in the world to use advanced tubular turbines technology.

Moving thousands of tons of coal per hour at high speeds through a complex handling system is a main cause of airborne coal dust in a coal-fired plant. Depending upon the coal’s characteristics, that dust can become explosive when its concentration reaches 80 g/m3 and, hence, a threat to life and property. The best option is to stop the dust from becoming airborne in the first place.

A new gas-fired power generation technology that uses an oxyfuel, high-pressure, supercritical carbon dioxide cycle and produces pipeline-ready carbon dioxide for sequestration or use in enhanced oil recovery (EOR), without reducing plant efficiency, garnered the interest of three new partners in June.

New U.S. Environmental Protection Agency regulations affecting the nation’s coal power plants are routinely in the national news. The latest proposed rule focuses on the release of carbon dioxide into the atmosphere. With a substantial amount of coal generation expected to be shut down (up to 40 GW to 50 GW in the coming years by some accounts), the new regulations are increasing the likelihood that this lost capacity will not be replaced by new coal generation.

FP&L to Increase Output at Turkey Point. Florida Power & Light (FP&L) on June 19 received approval from the Nuclear Regulatory Commission to increase the power generating capacity of Turkey Point Nuclear Generating Units 3 and 4 by 15%. The power uprate for the pressurized water reactors will increase each unit’s capacity from approximately 700 […]

The world nuclear industry experienced few substantial changes in performance metrics for 2011—beyond Japan, that is. In the aftermath of Fukushima, the once–world leading Japanese nuclear industry fell to the bottom of the rankings, perhaps for good.

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the third chapter, “Micro-Mismanagement by Committee.” During the frenzy to manage atomic power after World War II, Congress created an executive branch agency that threatened to be too independent, too powerful, and too isolated from the rest of government. Compounding their errors, perhaps in recognition of what they had created, the solons also developed a way to insert their own power into the action. This proved to be a major mistake—blurring the lines between executive and legislative authority—causing no end of problems for the nation’s nascent atomic energy venture.

Camfil Farr Power Systems added two new products for dusty environments to its Campulse product line: Campulse GTC and GTD. Both have new, non-discharging fiber media, which are sturdy, durable, and offer high dust-holding capacity. The Campulse GTC’s smooth synthetic fibers offer low resistance to airflow and maintain a low pressure drop throughout the filter […]

Steve Elonka began chronicling the exploits of Marmaduke Surfaceblow—a six-foot-four marine engineer with a steel brush mustache and a foghorn voice—in POWER in 1948, when Marmy raised the wooden mast of the SS Asia Sun with the help of two cobras and a case of Sandpaper Gin. Marmy’s simple solutions to seemingly intractable plant problems remain timeless. This Classic Marmaduke story, published more than 50 years ago, reminds us that an overhaul or startup may not go as planned, but it can still have a happy ending.
