| Abstract Scope |
The epithermal beamline at Washington State University’s Dodgen Research Facility was utilized to interrogate the influence of neutron irradiation on vapor pressure over hydrided getters. Neutrons produced in WSU’s TRIGA Reactor were collimated and reduced to a 2-inch beam prior to interacting with the hydrided getter sample inside the measurement apparatus. Samples evaluated in this study consisted of nickel-plated zirconium alloy tubes hydrided to an H/Zr ratio of 0.4. Previously established pressure-composition-temperature diagrams provide the temperature dependence of the vapor pressure exerted by hydrided zirconium at relatively high temperatures (> 500°C). Low-temperature data are more challenging to obtain due to the corresponding lower pressures and the influence of neutron irradiation is unknown. Although it was hypothesized that neutron irradiation may enhance vapor pressure, data measured in this study show indicate vapor pressures are not increased by an epithermal neutron flux of 1x109 n/cm2-s in the temperature range of 275°C -400°C. |
