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 investigations of the tritium distribution in a surface layer and in the depth of samples using a magnetic microscope were carried out. The dependence of a saturation level in the boundary layer for hydrogen was established from a preliminary examination of samples. Conservation of the tritium distribution profile in the depth of the stainless steel samples after completion of their saturation and cooling was assigned. For Inconel-625 substantial tritium redistribution and release during storage (300K, 15 and 28 months) were experimentally ascertained to a greater degree satisfies the classical characteristics of the diffusion process. The "braking" effect of tritium diffusion was found by preliminary saturation of samples by hydrogen. Research in tritium decontamination effects for samples saturated with tritium with various technological preparation was carried out and essential increase of its efficiency was founded. The experiments emulated a model of technological operation cycle of the thermonuclear reactor.
