A new tool that can be used to help ensure the proper positioning of core shroud head bolt assemblies in boiling water reactors (BWRs) was recently invented by Jason Cocke, engineering, tooling, and logistics

When management decided to purchase and install a new, vented lead-acid battery system at the Dogwood power plant, decision-makers also investigated the benefits of adding a continuous battery-monitoring

Keeping a power plant’s surface condenser in proper working order requires paying attention to balance-of-plant systems as well. Failure to monitor and maintain cooling towers and vacuum pumps in particular can lead to performance penalties or worse. The surface condenser at a power plant has a significant effect on power generation—specifically, the efficiency with which […]

Two senior power sector executives opened the 2016 ELECTRIC POWER Conference and Exhibition in New Orleans April 19 with a message that generators need to “think big” and embrace possibilities of disruptive technologies—or risk being run over on the road to the future. Leo Denault, chairman and CEO of Entergy Corp., delivered the opening keynote […]

A great level of risk is present when operating pressurized systems. Over the years, industry safety concerns have increased with the occurence of catastrophic events. To help prevent further loss and damages

Blades are probably the most delicate part of a wind turbine and the most susceptible to accidental damage. Some estimates suggest that greater than 90% of wind turbine blades are damaged to some degree while

If you’re still thinking of drones and robots as more toy than tool, think again. The drones now working in the power sector have gone far beyond remote-control hobbies and now resemble something closer to

In 2000, the world had installed just 1 GW of solar photovoltaic (PV) capacity (in DC terms—see the sidebar, “AC or DC?”), a number that had surged to 39 GW by 2010 and 176 GW in 2014. Fueled by

In the January issue, I introduced the concepts of highly reliable organizing (HRO) and resilience engineering with a promise to address the remaining principles. As a quick review of the first article

Although other renewable sources of energy may be growing at a faster rate, more electricity continues to be generated in the U.S. by conventional hydropower than by wind, solar, and geothermal power combined
