Nuclear

The year 2008 is shaping up nicely for nuclear power in the U.S. Since September 2007, when NRG Energy and the South Texas Project Nuclear Operating Co. filed the first complete U.S. nuclear plant license application in 29 years with the Nuclear Regulatory Commission (NRC), a dozen more companies and consortia have followed suit. And […]

A familiar argument against building new nuclear power plants in the U.S. is that there’s no long-term solution to the used nuclear fuel storage problem. This situation was created in 1977 with the indefinite suspension of programs to reprocess commercial used nuclear fuel. The Global Nuclear Energy Partnership’s announcement in February 2006 that it was reconsidering the reprocessing of used nuclear fuel represented a major shift in policy. It may even open the door to building new U.S. nuclear plants.

It is rare indeed to witness, at an otherwise staid industry forum, the public rebuke of the country’s most prominent supplier to the electric power industry. But at the Keynote session and Power Industry CEO Roundtable of the 2008 ELECTRIC POWER Conference & Exhibition in Baltimore this May, Milton Lee, general manager and CEO of […]

A week before the Preakness and two weeks after the Kentucky Derby, it was an atomic horse race in Baltimore. Reactor vendors trotted out their technologies at the ELECTRIC POWER Conference & Exhibition in sessions that filled the nuclear track’s 96-seat room at the Baltimore Convention Center. The reactor makers were also soliciting help from […]

The nuclear renaissance is likely to slow next year with a new tenant in the White House and many key regulatory positions in flux. Nuclear industry leaders are especially concerned that rules for construction loan guarantees will fall victim to the “wait and see” disease that infects those inside the Beltway every four years. If those rules aren’t in place before this November’s election, the nuclear renaissance may revert to the Dark Ages.

Dozens of intrinsically safe Generation III+ reactors are expected to be deployed in the U.S. in the coming years. Today, scientists already are looking over the horizon to Generation IV reactors that will be capable of producing hydrogen and process heat as well as electricity while generating much less radioactive waste.

I was talking with a utility executive the other day about his recent vacation in India. It’s certainly not your usual holiday destination, but he’s the adventurous type, eager to mingle with different cultures and sample their cuisine. The exec did a lot more than tour the Taj Mahal and get a glimpse of endangered […]

In our second annual report on the state and future of the U.S. power generation industry, we combine the considerable experience of POWER’s editorial staff with the market savvy of Industrial Info Resources Inc. (see next story) to preview the industry’s direction in 2008. We anticipate that the specter of carbon control legislation will hobble coal and make renewables the hot ticket while nukes continue to inch forward in a generation market that is basically treading water.

Industrial Info Resources’ strengths are tracking capital projects and cost projections and providing intelligence about the power generation market, among others. IIR has used its large industry databases and numerous industry contacts to develop its outlook for 2008. Here’s what you should expect and plan for this year.

In the U.S. today, there are continual discussions about energy independence, energy security, and ways to slow climate change. But meeting the nation’s projected 40% increase in electricity demand by 2030, while reducing overall power plant CO2 emissions, will require much more than talk. During the 1990s, American utilities increased their gas-fired generating capacity because […]

  Early last month, Governor Eliot Spitzer and Attorney General Andrew M. Cuomo—both New York Democrats—asked the U.S. Nuclear Regulatory Commission (NRC) to reject Entergy Nuclear’s application to extend the operating licenses of Indian Point Units 2 and 3 for 20 years. The units, each rated at about 1,000 MW, are a major source of […]

How do you know if a pressure transmitter is giving poor results? Unless the transmitter actually fails, most operators won’t notice a very slow loss in accuracy or response time. Fortunately, the noise analysis technique can identify such changes before they cause a problem. The technique has been used to effectively measure the dynamic response of nuclear power plant pressure sensors and their associated sensing lines. It also can be applied to any plant that relies on accurate instrumentation for control and monitoring plant performance.

The eyes of Texas—and the rest of the world—are upon NRG Energy after its September application for licenses for two new reactors at South Texas Project (see Global Monitor). The filing was the first of its kind in nearly three decades and the first of up to 30 like it expected over the next few […]

TVA’s 1,155-MW Browns Ferry Unit 1 returned to service on May 22 after sitting idle since 1985, when all three units were shut down to address management and operational concerns. Units 2 and 3 returned to service in 1991 and 1995, respectively, after extensive upgrades to controls, electrical systems, pumps, motors, and more. The return of Unit 1 began in 2002 with a five-year $1.8 billion restart plan to make all three units essentially identical, and that goal was accomplished in style. Welcome back, Unit 1.

A Luminant-Bechtel team completed replacement of four steam generators and the reactor vessel head—plus almost 200 other work packages—in a short, 55-day outage at Comanche Peak Unit 1. Matching or exceeding this schedule will become the goal for those who follow.

Detroit Edison teamed with Washington Group International to complete a first-of-its-kind nuclear retrofit project: replacing two moisture separator reheaters during a single 35-day outage with a perfect safety record. POWER recognizes this significant accomplishment by naming Fermi 2 Power Plant a 2007 Top Plant.

Just under a year ago, Omaha Public Power District completed perhaps the most complex nuclear power plant renovation in the history of the industry in a scant 85 days—five fewer days than the original plan called for. POWER recognizes Fort Calhoun Nuclear Generating Station as a Top Plant for packing more work into one outage than was thought possible, and then executing the plan ahead of schedule and below budget.

The U.S. is home to more than 30 boiling water reactors of BWR-3 through -6 vintage. At one time or another, all have experienced obsolescence, reliability, or control problems with their reactor recirculation flow control systems and components. Temporary down-powers are often required for corrective maintenance. Exelon Nuclear plans to begin upgrading the recirculation pump motor drives at its BWRs in the spring of 2009. The upgrade project’s technical design and business case were developed in great detail before the project was approved. This article presents the results of all key internal analyses.

Over the past few years, U.S. nuclear power plants have begun replacing their obsolete analog control systems with digital control systems. Many of these projects have been completed successfully, yielding a tidy return on investment in the form of increased generation. However, some have encountered difficulties, which resulted in cost overruns and schedule delays. This minority of projects may have eroded the industry’s confidence in digital upgrade projects, but a well-run project is still one of your best options for squeezing the last drop of performance out of your plant.
