    Impact of trapping on tritium self-sufficiency and tritium inventories in fusion power plant fuel cycles by Samuele Meschini, Rémi Delaporte-Mathurin, George R. Tynan, Sara E. Ferry

    Published 2025-01-01
    “…The novelty of this work is the integration of an explicit, physics-based model for tritium trapping, evolution of damage-induced traps, and component replacements into a dynamic, system-level model of a fuel cycle. The results show an increase of a factor $10^3 - 10^4$ of tritium inventory in the first wall and vacuum vessel of an ARC-class FPP when accounting for the aforementioned phenomena. …”
