Abstract: Generation IV reactor structural materials will be exposed to high doses and temperatures during reactor operation that may lead to irradiation-induced degradation. This degradation will differ from that seen in light water reactors and therefore understanding mechanisms controlling material performance during irradiation is critical for evaluating the viability of Generation IV nuclear reactor concepts. This chapter discusses irradiation effects and microstructural changes that affect mechanical properties and dimensional stability of Generation IV reactor materials.

Cluster dynamics models of irradiation damage accumulation in ferritic iron. I. Trap mediated interstitial cluster diffusion
Aaron A. Kohnert,Brian D. Wirth +1 more
TL;DR: In this paper, the formation of these defects is described as an aggregation process of smaller clusters created as primary damage, and multiple assumptions regarding the mobility of these damage features are tested in the models, both with and without explicit consideration of such irradiation induced hops.

A. J. Ardell
- 01 Jan 2008
TL;DR: The state of knowledge of radiation-induced solute segregation (RIS) in alloys is reviewed in this paper, with special emphasis on solute partitioning in steels, and some important outstanding issues that impact the current understanding of RIS are discussed.

Modeling of radiation-induced segregation at grain boundaries in Fe–Cr–Ni alloys
TL;DR: In this article, a model of radiation-induced segregation at grain boundaries in Fe-Cr-Ni alloys was carried out for wide ranges of temperatures, point defects generation rates and doses taking into account both the vacancy and interstitial mechanisms of the alloy components diffusion.

Post-irradiation deformation in a Fe-9%Cr alloy
David S. Gelles,Robin Schäublin +1 more
TL;DR: In this article, the deformation following irradiation is found to occur in poorly defined channels about 100 nm wide, causing formation of discrete steps at surfaces and, interestingly, designated by nonuniformly distributed highly elongated voids.
