Abstract

Implications for the use of the ppm to dpa ratio as a parameter for simulating the effects of helium generation rate on bubble nucleation and void swelling are examined. It is shown that neither the experimental nor the calculated results can be rationalized in terms of the ppm to dpa ratio. The analysis shows that the use of the ppm to dpa ratio can lead to unrealistic conclusions regarding the effects of helium atoms on grain boundary embrittlement and swelling under fusion irradiation conditions.
