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.

Idealized equilibrium expansion calculations were made to determine the characteristics of UO2 vapor bubbles produced under sodium in the capacitor discharge vaporization experiments at the Oak Ridge National Laboratory. These characteristics are the quality of the vaporized UO2, it vapor density, and the bubble diameter. A parametric study was made over the range of initial and final states expected to occur in the experiments to determine the effects of losing arbitrary amounts of energy and of vaporizing arbitrary amounts of sodium. The results are sufficiently general to be of use in estimating bubble characteristics for a hypothetical core disruptive accident in a liquid metal-cooled fast breeder reactor.
