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.

Delivering targets whose parameters are repeatable within specifications is critical to a successful ignition campaign. Knowing the repeatability of the metrology techniques and determining random error bars is central in achieving this goal. In this paper, we will discuss the relationship of specifications and actual target variability to the processes we have developed to adequately characterize them. The paper covers five broad categories of capsule specifications: dimension, composition, homogeneity, surface finish, and point defects. The instruments include contact radiography, energy dispersive spectroscopy, X-ray absorption edge spectroscopy, precision radiography system, sphere mapping, and phase-shifting diffraction interferometry.
