| Abstract Scope |
Tritium transport in tungsten plasma-facing components plays a central role in the performance, safety, and fuel economy of fusion energy systems. As an interstitial species, tritium migration governs retention, permeation, and losses, directly influencing fusion fuel cycle efficiency and component performance under reactor operating conditions. This work presents a multiphysics, multiscale modeling framework for predicting tritium behavior in tungsten using Tritium Migration Analysis Program 8 (TMAP8) and Software for Advanced Large-scale Analysis of MAgnetic confinement for Numerical Design, Engineering & Research (SALAMANDER), both built on the Multiphysics Object-Oriented Simulation Environment (MOOSE) framework. By coupling interstitial transport with other physics across scales, these simulations quantify the interactions between tritium diffusion, material response, and component-scale and fuel cycle performance. The results demonstrate that accurate representation of interstitial transport is essential for reliable prediction of plasma-facing component durability and tritium fuel cycle behavior, highlighting the outsized role of small atoms in fusion materials. |
