ORNL and EPRI built an enclosed welding system in a hot cell of ORNL’s Radiochemical Engineering Development Center. C. Scott White (ORNL) performs operations with remotely controlled manipulators and cameras.

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.

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...

COHERENT collaborators were the first to observe coherent elastic neutrino–nucleus scattering. Their results, published in the journal Science, confirm a prediction of the Standard Model and establish constraints on alternative theoretical models. Image c

After more than a year of operation at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

Jason Newby is a physicist in the Nuclear Security and Isotope Technology Division at ORNL.
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...

Two researchers from the Department of Energy’s Oak Ridge National Laboratory have been elected fellows of the American Nuclear Society. Alan S. Icenhour and Jess C. Gehin were recognized for their outstanding scientific and technical leadership in nuclear energy rese...
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 ...
