The Trump administration has revived the discussion of using Yucca Mountain in Nevada as a repository for the nation’s nuclear waste. Nevada officials remain opposed to the idea of putting spent nuclear fuel in long-term storage at a site about 100 miles from Las Vegas. But while a bill to resurrect Yucca Mountain as a […]

It is safe to say that all electricity customers want reliable and resilient power service. One way that some end-users are ensuring they get it is by investing in distributed energy resources and building microgrids. But rather than simply using these systems as emergency backups, more and more owners are finding ways to capture economic […]

A Massachusetts Institute of Technology (MIT) interdisciplinary study found that nuclear power has the potential to contribute greatly to the achievement of deep decarbonization goals, yet despite its promise, cost hinders the expansion of nuclear power. “The Future of Nuclear Energy in a Carbon-Constrained World” was released on September 3. It is the eighth in […]

 The Japanese government has pushed for the reuse of mixed-oxide (MOX) fuel in the country’s nuclear reactors, but utilities that finance the reprocessing have not funded those operations since fiscal year 2016, according to financial reports released by the power companies on September 2. Japan’s KYODO News reported that sources said 10 utilities, including Tokyo […]

Power plant control and monitoring can be complex given the need to integrate many different platforms. Adding to the complexity is the fact that HMI’s (Human-Machine Interface) supplied by the OEM often only interface with the OEMs controller and not with ancillary systems. Lastly, ongoing support and updates from the common operating system may be […]

Mechanical Dynamics and Analysis (MD&A) was contracted after a forced outage to perform a major overhaul on a cogeneration unit’s MS5001PA gas turbine, and to remove, test and inspect the generator field. Because the unit dispatches as baseload and the turbine is a critical asset, MD&A was asked to complete the repair work as quickly […]

Mechanical Dynamics and Analysis (MD&A) was retained by a utility to perform a stub-shaft repair of a generator rotor collector-end shaft. The customer reported that the generator rotor had suffered a collector ring failure and also a ground to the main shaft. Major arcing and heat damage occurred to the generator rotor forging shaft. The utility weighed […]

Mechanical Dynamics & Analysis (MD&A) experts recently performed a thermodynamic analysis to assist our client in converting their coal and natural gas plant to combined cycle operation. The customer was able to locate a gray market Gas turbine and Heat Recovery Steam Generator (HRSG). Our team modeled how each component would interact with one another, and were […]

MD&A’s San Antonio Service Center can extend the service life of gas turbine components whose OEM service limit has passed or whose configuration is no longer suitable to operate. Significant savings can be realized by opting for lower-cost repaired spares instead of new parts. Elevated temperatures take a big toll on gas turbine components. Repair […]
