Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

For the modeling of the one-dimensional interfacial area transport equation for adiabatic bubbly flow in vertical rod bundles, existing typical sink and source terms were reviewed. Based on the reviewed interactive mechanism of bubbles and turbulent eddies, newly interfacial area transport model with considering the effect of spacer grids has been proposed and evaluated by the experimental data with the mean relative error of 19.9% .
