The expected degradation of mechanical properties of structural materials under irradiation
(ie “in operation”) in nuclear components represents a significant challenge for the design to …

To better understand the thermal stability of dislocation loops formed by long-term neutron
irradiation in reactor pressure vessel (RPV) steels, in-situ scanning transmission electron …

Monte Carlo (MC) techniques are among the most used techniques for modeling materials
at the atomic scale, with those of molecular dynamics. The name MC comes from the fact …

Abstract Ferritic/Martensitic (F/M) steel T91 was irradiated in-situ to 4 and 10 dpa at 470° C
using 1 MeV Kr 2+. The microstructure evolution under irradiation was followed and …

For ferritic steels served as structural materials for future nuclear reactors, a large number of
helium atoms are expected to be introduced through transmutation reaction. Current …
