HRTEM Study of Irradiation-Induced Cavities in Oxide-Dispersed Ferritic Steel
TL;DR: In this paper, the structure of oxide nanoparticles and the effects of matrix/nanoparticle interfaces on irradiation-induced cavity nucleation and distribution in Fe-16Cr-4.5Al-0.37Y2O3 oxide-dispersed ferritic steel were studied using high-resolution transmission electron microscopy techniques.

Swelling in light water reactor internal components: Insights from computational modeling
TL;DR: In this article, a modern cluster dynamics model has been used to investigate the materials and irradiation parameters that control microstructural evolution under the relatively low-temperature exposure conditions that are representative of the operating environment for in-core light water reactor components.

Predicting microstructural evolution in fusion reactor environments: experimental imperatives and opportunities
TL;DR: In this article, the experimental and theoretical basis for predicting microstructural evolution in structural alloys in fusion reactor environments is reviewed, and three classes of possible experimental initiatives are described: identifying and quantifying important mechanisms and model parameters, and the second is intended to test integral models of the interacting evolutions leading to rapid void swelling.

Voids in Irradiated Stainless Steel
C. Cawthorne,E. J. Fulton +1 more
TL;DR: In this paper, electron microscope examination by the thin foil technique has been carried out on samples of stainless steel irradiated in the Dounreay Fast Reactor, either in the form of cladding on experimental fuel elements or as specimens intended for mechanical property tests.

Void Swelling in Metals and Alloys Under Irradiation: An Assessment of the Theory
TL;DR: In this paper, the theory of swelling is reviewed in terms of basic concepts and simulation and impurity effects, and the basic theory employs the formalism of chemical reaction rates, e.g., voids, dislocations, etc.
Journal ArticleDOI
Experimental effects of helium on cavity formation during irradiation—a review
TL;DR: In this paper, a review of cavity formation and swelling in non-fissile materials during neutron irradiation and charged particle bombardments is presented, which is explainable in terms of cavity nucleation on submicroscopic critical size gas bubbles, and on the influence of the neutral sink strength of such bubbles.

An improved equation of state for inert gases at high pressures
I.R. Brearley,D.A. MacInnes +1 more
TL;DR: In this paper, a hard sphere equation of state is developed in order to describe inert gas behaviour at high temperatures and/or pressures, and the use of the hard sphere EOS in modelling fission gas behaviour during a thermal transient is shown to be a more robust estimator of the fissure gas pressure in bubbles than the reduced van der Waals EOS.

Fission-fusion correlations for swelling and microstructure in stainless steels: Effect of the helium to displacement per atom ratio
TL;DR: In this article, the effects of the helium to displacement per atom ratio on microstructural evolution, with emphasis on austenitic stainless steels, were analyzed to determine mechanistic trends and a model calibrated to the fission reactor data was used to extrapolate to fusion conditions.
