As an alternative to titanium, consider highly alloyed stainless steels for your next tubing project.

A key maxim of the military is "train like you fight, and fight like you train." The same applies to emergency response training, which should be a part of a plant’s routine operation. Don’t risk waiting until an accident occurs to test your response plan. At approximately 8:30 a.m. on a Tuesday morning, the Paducah […]

For busy staff in the field, nothing is more frustrating than having laptop computers or smart phones crash due to lost connections when those devices lose wireless coverage. Often, important data is obliterated and workers have to waste precious time reentering the lost information. The irony is that wireless data connections, which are increasingly being […]

In 2005, Jersey Central Power & Light (JCP&L), a subsidiary of Akron, Ohio – based FirstEnergy Corp., initiated a project to identify protection system improvements that could be made to proactively combat wind- and lightning-related weather events that create sustained power outages (Figure 2). JCP&L determined that these changes had the potential to improve the […]

Software ranges from shrink-wrapped products available “off the shelf” to custom corporate implementations of enterprise systems that require sessions with shrinks to keep everyone sane. Regardless of its complexity, every piece of software a plant uses, or interfaces to, poses critical issues that require life-cycle management. Although functionality has always been the chief specification for software, plants must pay far more attention to long-term quality issues. These two concerns are often at odds with each other.

An increasing number of low-pressure steam turbines—especially at supercritical fossil units—have experienced stress corrosion cracking in the blade attachment region of their low-pressure rotors. Approaches to solving this problem range from redesign of the attachment and blade replacement to in-situ weld repair. Regardless of the procedure selected, the solution must completely restore the turbine performance while minimizing outage duration.

Entergy christened its Performance Monitoring and Diagnostic Center several years ago to leverage the expertise of its most senior operators and technicians across the company’s entire fleet of plants. The center also makes use of advanced software tools that increase plant availability and reliability by identifying faults before they become major, unplanned outages. The center paid for itself for years to come with a single “big catch” last year.

The power industry’s operating and maintenance practices were held up to intense regulator and public scrutiny when on November 6, 2007, a Massachusetts power plant’s steam-generating boiler exploded and three men died.

Chromium-molybdenum (chrome-moly) pipe has become a standard in the power generation industry, not only because of its corrosion resistance and high-temperature strength, but also for its cost-effectiveness. In many applications, it is a viable alternative to a more costly stainless steel pipe.

Spurred on by a recent audit showing widespread utility noncompliance with voluntary recommendations meant to protect the grid from cyber attacks, key lawmakers have unveiled plans to give the Federal Energy Regulatory Commission (FERC) broad powers to enact new mandatory measures to close vulnerabilities in the U.S. bulk power system to potentially devastating computer-launched assaults.
