Nearly 200 attendees from national labs, industry, utilities, reactor design firms, and international development companies gathered at ORNL’s latest molten salt reactor workshop.

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,...

Doctoral student Rachel Seibert works with ORNL mentor Kurt Terrani as part of the lab’s Nuclear Engineering Science Laboratory Synthesis (NESLS) program.
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 ...

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...

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.
