Arc flash is arguably the most deadly and least understood hazard faced daily by plant personnel. Research indicates that even the best safety plan, training regimen, and protective equipment may be no match for the heat and blast effects of an arc flash. Consider this article a wakeup call to retrofit every switchgear cubicle in your plant with a properly designed remote racking system. Forewarned is forearmed.
One expert has called it the "digital delta"—the seemingly endless challenges in refurbishing U.S. nuclear plants with digital instrumentation and controls. But it appears more like a deep ditch, where even those seeking to license new reactors could get stuck. Here’s the latest on the issues, experience, and results—plus recommendations for getting the industry out of the mud and back on the road.
Following the money invested in projects is a viable way to compare growth trends for power projects using the four major generation types: coal, natural gas, nuclear, and renewable.
Forecasting the direction of the U.S. electric power industry for 2007, much less the distant future, is like defining a velocity vector; doing so requires a direction and speed to delineate progress. In this special report, POWER’s first stab at prognostication, the editors look at current industry indicators and draw conclusions based on their more than 100 years of experience. To borrow verbatim the title of basketball legend Charles Barkley’s book: I May Be Wrong but I Doubt It.

An offshoot of the 1993 Megatons to Megawatts nonproliferation program, the Blended Low-Enriched Uranium (BLEU) project has modified and developed new fabrication processes for converting surplus weapons-grade uranium materials into nuclear fuel for TVA’s Browns Ferry Nuclear Plant. This innovative public/private venture continues to deplete nuclear arsenal stockpiles while reducing storage, security, and disposal costs to U.S. taxpayers.

This year’s main course, as usual, was instrumentation and controls. Side dishes of digital nuclear plant controls, plant controller and IT security, corrosion monitoring, and model predictive control added their own distinctive flavors. There was something for every taste, from the theoretical to the practical.
