Comparison of the swelling and the microstructural/microchemical evolution of AISI 316 irradiated in EBR-II and HFIR
The microstructural and microchemical evolution has been compared for one heat of cold worked 316 stainless steel irradiated in both HFIR and EBR-II at 500 to 620/sup 0/C. The dislocation and cavity densities and the swelling at high fluence are remarkably insensitive to the over two orders of magnitude difference in helium/dpa ratios. While the microchemical evolution is also largely unaffected, minor differences were observed possibly arising from solid transmutants that form only in HFIR. The reported absence of ..gamma..' phase in specimens irradiated in HFIR at these temperatures reflects its sluggish formation in both reactors. The microchemical evolution is accompanied by the development of a swelling rate typical of steels irradiated in fast reactors. The magnitude of this swelling rate is corroborated by HFIR data on this same heat in the solution annealed condition.
