In-situ TEM study on the evolution of dislocation loops and bubbles in CeO2 during Kr+single-beam and Kr+-H2+dual-beam synergetic irradiation
文献摘要：
CeO2 is widely used as the nonradioactive surrogate fuel of UO2 when studying the irradiation perfor-mance of UO2.The evolution and characteristics of dislocation loops and bubbles in CeO2 foils were studied by in-situ transmission electron microscopy(TEM)observation during 400 keV Kr+&30 keV H2+dual-beam synergetic irradiation and 400 keV Kr+single-beam irradiation at 1073 K.The rotation of the habit plane of dislocation loops induced by above ion irradiation was found in the CeO2 for the first time,such as from[211]to[311]and then to[100].The rafted loops were first observed under Kr+&H2+dual-beam synergetic irradiation,which not only had similar[111]direction,but also belonged to perfect dislocation loops(PDLs).The rafted loops were formed not only by the growth of loops that absorbed irradiation defects,but also by the combination of loops.But,this phenomenon of loop rafting was not obvious during Kr single-beam irradiation.It was first found that Kr+irradiation induced the change of Burgers vectors of PDLs.The absorption of large PDLs to small PDLs was also observed.The average size and areal number density of dislocation loops and gas bubbles as a function of irradiation dose were constructed,which showed that the addition of H2+obviously affected the characteristics of dislocation loops and gas bubbles and the swelling of CeO2.
