Radiation-induced volumetric expansion (RIVE) is a concern for any concrete structures that are exposed to neutron flux and other types of radiation that affect crystalline structures within the ...

As night descends on the Department of Energy’s Oak Ridge National Laboratory, the High Flux Isotope Reactor (HFIR) bursts with activity. A rigorous 24-day fuel cycle concludes and neutron production ...

One of the four missions at DOE’s High Flux Isotope Reactor is neutron scattering, a research technique used to study matter at the atomic scale. These neutrons are produced at HFIR through fission, ...

Oak Ridge National Laboratory’s High Flux Isotope Reactor (HFIR), one of the world’s most powerful research reactors, is marking a milestone this month — its 400th fuel cycle since it began operation ...

This paper presents a novel approach, ReactorNet, a machine learning framework leveraging thermal neutron flux imaging to enable real-time monitoring of pressurized water reactors (PWRs). By ...

Neutron transport and reactor physics analysis form the theoretical and computational foundation for the design, operation and safety assessment of nuclear reactors. At its core lies the neutron ...

It's been known for some time that radiation impacts the structural integrity of concrete. However, until now the details of this were unknown. Researchers can finally demonstrate what properties of ...
