Deuterium plasma discharges of the Divertor Tokamak Test facility (DTT) in different operational scenarios have been predicted by a comprehensive first-principle based integrated modelling activity using state-of-art quasi-linear transport models. The results of this work refer to the updated DTT configuration, which includes a device size optimisation (enlargement to  m and a = 0.70 m) and upgrades in the heating systems. The focus of this paper is on the core modelling, but special attention was paid to the consistency with the scrape-off layer parameters required to achieve divertor plasma detachment. The compatibility of these physics-based predicted scenarios with the electromagnetic coil system capabilities was then verified. In addition, first estimates of DTT sawteeth and of DTT edge localised modes were achieved.

Divertor Tokamak Test施設(DTT)における異なる運転シナリオでの重水素プラズマ放電は、最先端の準線形輸送モデルを用いた包括的な第一原理に基づく統合モデリング活動によって予測された。これらの結果は、装置サイズの最適化( mへの拡大およびa = 0.70 m)と加熱システムのアップグレードを含む、更新されたDTT構成に関するものである。本論文の焦点はコアモデリングにあるが、ダイバータプラズマ剥離を達成するために必要なスクレイプオフ層パラメータとの整合性には特に注意が払われた。これらの物理に基づく予測シナリオと電磁コイルシステムの適合性も検証された。さらに、DTTのソーテインおよびDTTのエッジ局在モードの最初の推定が達成された。
