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.

The extrapolation distance ϵ at the surface of a grey cylindrical control rod of given size is found in terms of the blackness β of the rod and in terms of the extrapolation distance ϵb at the surface of a black rod of the same size. The formula is where λe is the transport mean free path in the region external to the rod. Tables are provided for β and an empirical expression for ϵb/λe is given.
