A major part of maintaining a power plant at peak efficiency is dealing with or preventing damage from corrosion and corrosive objects that can enter air and water intake systems, including pipes and fluid

The hard realities of an energy system based on renewables will soon be with us, causing far more problems than are realized. Renewables don’t offer a quick fix, and we need to get the transition from

A new report released July 31 details continued growth in global energy storage, driven by lower costs for lithium-ion batteries. Research company BloombergNEF (BNEF) in its latest forecast published Wednesday said energy storage installations worldwide will grow across the next two decades, from the 9 GW/17 GWh of capacity deployed as of last year, to […]

A team that reviewed Southern Nuclear Company’s (SNC’s) April 2019 Vogtle Units 3 and 4 Re-baseline of Forecast Schedule and Cost said it believes the working schedule predicated on commercial operation dates of May 23, 2021, and May 23, 2022, for the respective units, is unachievable. Furthermore, the reviewers said the regulatory-approved schedule from the […]

Elevated temperatures take a big toll on gas turbine components risking cracks, corrosion, wall thickness, and material condition. Repair enhancements can extend a part’s life by slowing its degradation and pushing out its usable service life. Operators can see significant savings by opting for lower-cost repaired spares instead of new parts as demonstrated in the following case studies.

On July 29, 1949, at 2:15 p.m., General Electric’s (GE’s) first gas turbine at the Belle Isle Station in Oklahoma City began delivering power to Oklahoma Gas and Electric Co.’s distribution system. The 3.5-MW GE Frame 3 machine reportedly had an efficiency of about 17%. Since the Belle Isle machine (Figure 1) started up seventy […]

NuScale Power, Rolls-Royce, and China National Nuclear Corp. (CNNC)—three companies working on different small modular reactor (SMR) technology—recently announced positive developments for their respective designs. NRC Makes Progress on NuScale Design Review Portland, Oregon-based NuScale said on July 22 that the U.S. Nuclear Regulatory Commission (NRC) completed the second and third phases of its SMR […]

BHP and Mitsubishi Development Pty (MDP) in late June signed a memorandum of understanding for joint research, development, and deployment of greenhouse gas emissions reduction technologies in several countries, including projects with battery storage, solar, and carbon capture and storage (CCS). The agreement, signed in Tokyo, Japan, on June 20, also calls for research into […]

Nuclear power advocates suggest there are many benefits associated with nuclear energy. They point to high-paying jobs; billions of dollars in economic activity for plant-hosting communities; and secure, reliable, baseload electricity. But the most-important benefit of nuclear power may be that it emits no greenhouse gases, and therefore does not contribute to climate change. According […]

Tokyo Electric Power Co. (TEPCO) on July 24 said it will decommission its Fukushima Daini nuclear station. The plant is located just south of the larger Fukushima Daiichi plant, site of a meltdown in March 2011 after an earthquake and tsunami heavily damaged the Daiichi facility. The four reactors at Daini automatically shut down after […]
