Test for Reactor Vessel Damage Assessment

Posted January 20, 2017 12:00 AM by Engineering360 eNewsletter

An analytical method pioneered by MIT researchers could change the way operators measure damage to nuclear reactor vessels. This method could potentially provide continuous monitoring and prevent unnecessary replacement of materials. The testing method uses acoustic vibrations to gauge material damage levels.

Safer Way to Install Offshore Wind Turbines

Posted November 26, 2016 12:00 AM by Engineering360 eNewsletter

Installing offshore wind turbines in open water presents plenty of risks to workers. To improve safety and save costs, researchers from the EU-funded ELISA Project have developed a new system where turbines can be completely pre-assembled and pre-commissioned in controlled harbor conditions. The assembled and tested units are then installed offshore without the need for heavy-lift vessels. Engineering360 shares fascinating details about how the installation procedure works, noting that one fully operational 5 MW prototype already exists in the Canary Islands. Engineers believe the ELISA process could reduce installation costs by 30-40% over traditional systems while improving worker safety substantially.

Improving Steam Turbine Reliability

Posted November 01, 2016 12:00 AM by Engineering360 eNewsletter

Spinning at up to 3600 rpm, turbines and generators are subject to failure, and that's a critical problem in power gen facilities worldwide. Second only to boiler tube failures as a cause of downtime, turbine outages are responsible for millions of dollars of lost power generation. When those failures occurred in the past, the causes were often unknown, meaning repeat failures of the same type were common. But with turbine and generator equipment replacements becoming cost-prohibitive, it's essential that turbine life extension strategies be put in place. Engineering360 looks at what can be done to enhance turbine life and reliability.

Full Steam Ahead!

Posted September 23, 2016 12:00 AM by Engineering360 eNewsletter

Steam is responsible for generating 80% of the world's power. It's required for coal, combined-cycle natural gas, nuclear, geothermal, and even concentrated solar plants. Steam has played a key role in power generation for nearly 100 years, so what does the future hold for this venerable technology? Engineering360 dives deep into the history of steam turbines, noting basic designs haven't changed much at all, before looking at possible enhancements to existing techniques and systems. Will these turbines still factor in if renewable energy replaces traditional sources? And why has no other technology proven as effective at transforming thermal energy to mechanical energy?

Preventing HRSG Failures

Posted September 04, 2016 12:00 AM by Engineering360 eNewsletter

Combined-cycle natural gas generation is quickly proving to be a popular alternative to both traditional coal power and renewables, because it can ramp up output quickly. But is the growing popularity of this technology resulting in increasing heat recovery steam generator (HRSG) failures? Engineering360 says cycling of combined-cycle plants has led to abuse of HRSG pressure components since most were not designed to withstand the stress caused by faster startups and low-load operations. Here is an up-close look at the most common types of HRSG failures, their causes, and what can be done to prevent them.
