Influence of temperature, initial grain-boundary bubble density and grain structure on fission gas behaviour in UO: a 3D hybrid multiscale study
Sourav Chatterjee, Md. Ali Muntaha, Sophie Blondel +3
Fission gas swelling and release in UO are governed by the coupled evolution of intragranular clusters and bubbles, migrating grain boundaries (GBs), triple junctions (TJs), an…

Simulations of grain growth in tungsten armor materials under ARC plasma edge operation conditions using an integrated plasma-edge/materials model
Jinxin Yu, Nithin Mathew, Sophie Blondel +5
An integrated model of grain growth deuterium-exposed tungsten polycrystals, consisting of a two-dimensional vertex dynamics model fitted to atomistic data, has been developed to a…

Impact of grain boundary and surface diffusion on predicted fission gas bubble behavior and release in UO fuel
Md Ali Muntaha, Sourav Chatterjee, Sophie Blondel +4
In this work, we quantify the impact of grain boundary (GB) and surface diffusion on fission gas bubble evolution and fission gas release in UO nuclear fuel using simulations w…
