Unique system for welding highly irradiated metal alloys

12-Feb-2018

Scientists of the Department of Energy's Light Water Reactor Sustainability Program (LWRS) and partners from the Electric Power Research Institute (EPRI) have conducted the first weld tests to repair highly irradiated materials at DOE's Oak Ridge National Laboratory. The welding system, designed ...

Model predicts scenarios for energy generation using nuclear fusion

31-Jan-2018

Nuclear fusion, for the controlled and regular generation of electric power by converting hydrogen into helium and reproducing on a small scale what happens in our Sun (as well as other stars), is one of the foremost technological promises for the decades ahead. Designed to reach parameters ...

IceCube experiment finds Earth can block high-energy particles from nuclear reactions

24-Nov-2017

For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of ...

A detailed look at 2-D structure of turbulence in tokamaks

17-Oct-2017

A key hurdle for fusion researchers is understanding turbulence, the ripples and eddies that can cause the superhot plasma that fuels fusion reactions to leak heat and particles and keep fusion from taking place. Comprehending and reducing turbulence will facilitate the development of fusion as a ...

New model for bimolecular reactions in nanoreactors

07-Aug-2017

Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts. They gained surprising new insights as to what factors promote reactions and how to control and select them. The model is relevant for a wide range of ...
