When whistler waves are present in a fusion plasma, runaway electrons pay attention.
A research team led by the Department of Energy’s Oak Ridge National Laboratory is the first to directly observe the elusive waves inside a highly energized magnetic field as electrons zoom ar...
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...
Not everyone can look back on their life and pick the specific instance that brought them to their current field and dictated the course of their career. For Jason Newby, that instance was a high school physics class that would eventually lead to him studying nuclear technology and i...
When it comes to a challenging application for embedded instrumentation and control, none quite beats an environment of molten salt at 700 degrees Celsius. But that is just the application chosen by scientists at the US Department of Energy’s Oak Ridge National Laboratory...
Renewed interest in molten salt technology was evident at a recent gathering of advanced nuclear reactor experts at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL). Nearly 200 attendees from national labs, industry, utilities, reactor design firms,...
For a second straight summer, Rachel Seibert spent her days at the Department of Energy’s Oak Ridge National Laboratory (ORNL) researching advanced nuclear reactors. The Ph.D. candidate may not have had such an opportunity more than a decade ago, but thanks to a unique internship ...
Moving advanced nuclear reactors from the drawing board to the field was the focus of the Advanced Reactors Technical Summit III, hosted by the Department of Energy’s Oak Ridge National Laboratory and attended by 180 experts from industry, government and academia. The conference, ...
When it’s up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other hand, will be small and very cold. Pellets of frozen gas will be shot int...
Blowing bubbles may be fun for kids, but for engineers, bubbles can disrupt fluid flow and damage metal.
Researchers at the Department of Energy’s Oak Ridge National Laboratory got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra “switch” that brings new functionalities to materials when “flipped” by external stimuli such as electric fields or mechanical strain. This makes polar materials useful for devices such as sensors and actuators.
