“…For the sake of simplicity the damage will be cited as simply dpa from now onwards. First irradiation experiment was conducted at 450 C using 10 MeV Fe 5þ ions in electrostatic accelerator connected to a triple beam chamber at JANNuS facility of CEA Saclay [29]. Targeted doses were 5 and 10 dpa at the surface with a dose rate of 2.7 Â 10 À4 dpa/s (calculated at the surface).…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. Proton irradiation is generally used as a representative alternative of neutron irradiation to improve the current understanding of the mechanisms involved in IASCC. This study assesses the possibility of using heavy ions irradiation to evaluate IASCC mechanisms by comparing the irradiation induced modifications (in microstructure and mechanical properties) and cracking susceptibility of SA 304 L after both type of irradiations: Fe irradiation at 450 C and proton irradiation at 350 C. Irradiation-induced defects are characterized and quantified along with nano-hardness measurements, showing a correlation between irradiation hardening and density of Frank loops that is well captured by Orowan's formula. Both irradiations (iron and proton) increase the susceptibility of SA 304 L to intergranular cracking on subjection to Constant Extension Rate Tensile tests (CERT) in simulated nominal PWR primary water environment at 340 C. For these conditions, cracking susceptibility is found to be quantitatively similar for both irradiations, despite significant differences in hardening and degree of localization.

“…High temperature helium embrittlement could also potentially be a problem [4e7]. Before a facility like IFMIF [8] that will produce high fluxes of 14 MeV neutrons is available, one of the best ways to study the combined effects of irradiation and simultaneous gas production is a multibeam ion-irradiation facility like JANNUS Saclay [9,10]. In this paper we present results concerning the microstructure of EUROFER-97 and EUROFER-ODS (0.5wt.%Y 2 O 3 ) steels after ion-irradiation.…”

a b s t r a c t RAFM steels such as Eurofer-97 and Eurofer-ODS are potential structural materials for future fusion reactors. In order to study their resistance to the high energy neutrons they will be subjected to in this context, we have irradiated these materials in single-, dual-and triple-beam mode to 26 dpa at 400 C. In single-beam mode (Fe ions only), both materials resist swelling but dislocation loops form. For dual-(Fe and He ions) and triple-beam (Fe, He and H) modes, the same dislocation loop microstructure is observed as for the single-beam mode, but small cavities form, aided by the presence of gases. Despite the formation of cavities, swelling is very low for the present conditions. The influence of ODS particles on swelling is briefly discussed.
