Popis:	This paper discusses a possible role of grain boundary cavities in the high temperature irradiation embrittlement (HTIE) of reactor structural materials. It is demonstrated that grain boundary voids alone can hardly provide the dominance of intergranular fracture mode during HTIE. An alternative mechanism based on the growth of helium accumulating cracks is discussed and the resulting predictions for material failure parameters are presented.
