Description/Abstract:
Ten fuel elements have completed 4440 hours of endurance testing at 1200°F after receiving: 1. Thermal cycling, 2. High level vibration and shock, 3. Isothermal ramp heating. There is no evidence that any of these inputs damaged the ceramic hydrogen barrier of these elements. The ten fuel elements have lost an average of 0.2% of their hydrogen during 4440 hours of endurance. The average permeation rate of seventeen fuel elements, after reference level gradient ramp heating, shows no indication of any degradation of the ceramic hydrogen barrier. However, the permeation of one of the seventeen elements increased from 0.52 to 1.15 after this input.
