INL researchers use LEDs to shed light on next-gen reactors
At Idaho National Laboratory, researchers have built a bridge between computer models and the lab’s Microreactor Applications Research Validation and Evaluation (MARVEL) microreactor.
Tony Crawford, an INL researcher and MARVEL’s reactivity control system lead, designed a phone booth–sized surrogate nuclear reactor called ViBRANT, or Visual Benign Reactor as Analog for Nuclear Testing, which uses light instead of neutrons to show a “nuclear” reaction.

Interactive graphic techniques have been employed to analyze and interpret the discrepancies found between the integral measurement and the prediction of neutron flux in sodium. Direct adjustments have been made to improve the calculation-experiment agreement in the 10-keV to 1-MeV energy range. In general, the adjusted values for elastic cross sections have been found to be lower than the ENDF/B-IV values. Sensitivity of sodium spectra to the angular distribution of elastically scattered neutrons has also been determined.
