The interior of the Massachusetts Institute of Technology’s (MIT’s) Alcator C-Mod tokamak. A team led by Princeton Plasma Physics Laboratory’s C.S. Chang recently used the Titan supercomputer

The same fusion reactions that power the sun also occur inside a tokamak, a device that uses magnetic fields to confine and control plasmas of 100-plus million degrees. Under extreme temperatures and pressure, hydrogen atoms can fuse together, creating new helium atoms and simulta...

An image of a complete 7HA.02 gas turbine. The new GE turbine is capable of achieving an overall efficiency of more than 62 percent in a combined-cycle power plant and is projected to exceed world-record efficiency marks set by GE’s 9HA turbine model.
In 2017, US-based General Electric (GE) delivered its newest heavy-duty gas turbine, the 7HA.02, to two power plants in Texas. The installations marked a milestone in natural gas–derived electricity generation, setting new marks in efficiency and emissions for utility-scale turboma...

The Big Bang began the formation and organization of the matter that makes up ourselves and our world. Nearly 14 billion years later, nuclear physicists at the Department of Energy’s Oak Ridge National Laboratory (ORNL) and their partners are using America’s most powerful supercomp...

Oak Ridge National Laboratory scientists have developed a technique for making ultrafast measurements using atomic force microscopy, which previously could only investigate slow or static material structures and functions. In AFM, a rastering probe maps a material’s surface and cap...
ORNL’s 2017 Molten Salt Reactor Workshop offered a wide range of talks on advanced reactors, including modeling and simulation techniques, commercial licensing strategies and the Department of Energy’s efforts to work with industry on developing designs.

The third annual Molten Salt Reactor Workshop allowed leading voices on advanced reactors—including scientists from the national laboratory system, the Nuclear Regulatory Commission, reactor design firms and universities—to discuss current efforts in molten salt reactor work and pu...

It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. They found that aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles by about 10 to 40 percent in stop-and-go traffic and roughly 15 to 30 percent at highway speeds. This can equate to losing about $0.25 to $1 per gallon.
