| Abstract Scope |
YH is a potentially useful material as a microreactor moderator due to its high hydrogen concentration and desirable thermal properties. Despite these attributes, both radiation effects and hydrogen diffusion may pose challenges to its use in reactor systems. To test the viability of YH, this talk will highlight the effects of 3 MeV or 100 MeV proton irradiation on its microstructure, mechanical properties, and H concentration. Through the use of micro-mechanical tests, we will decipher the effects of local grain orientation on the strength of YH under various irradiation conditions. X-ray tomography will elucidate internal changes due to ion bombardment and electron microscopy will investigate the differences in radiation induced defects on the nanoscale. Finally, a combination of Raman Spectroscopy, Elastic Recoil Detection, and H desorption will elucidate H stability following irradiation. This work will advance the understanding of YH in irradiation environments for advanced nuclear reactors. |
