The 'European Transport Simulator' (ETS) (Coster et al 2010 IEEE Trans. Plasma Sci.38 2085–92, Kalupin et al 2011 Proc. 38th EPS Conf. on Plasma Physics (Strasbourg, France, 2011) vol 35G (ECA) P. 4.111) is the new modular package for 1D discharge evolution developed within the EFDA Integrated Tokamak Modelling (ITM) Task Force. It consists of precompiled physics modules combined into a workflow through standardized input/output data structures. Ultimately, the ETS will allow for an entire discharge simulation from the start up until the current termination phase, including controllers and sub-systems. The paper presents the current status of the ETS towards this ultimate goal. It discusses the design of the workflow, the validation and verification of its components on the example of impurity solver and demonstrates a proof-of-principles coupling of a local gyrofluid model for turbulent transport to the ETS. It also presents the first results on the application of the ETS to JET tokamak discharges with the ITER like wall. It studies the correlations of the radiation from impurity to the choice of the sources and transport coefficients.

「欧州輸送シミュレータ」(ETS)(Coster et al 2010 IEEE Trans. Plasma Sci.38 2085–92、Kalupin et al 2011 Proc. 38th EPS Conf. on Plasma Physics (Strasbourg, France, 2011) vol 35G (ECA) P. 4.111)は、EFDA統合トカマクモデリング(ITM)タスクフォース内で開発された、1次元放電発展のための新しいモジュール型パッケージである。これは、標準化された入出力データ構造を通じてワークフローに組み合わされた、事前コンパイル済みの物理モジュールから構成される。最終的には、ETSは、制御器およびサブシステムを含む、立ち上げから電流終了段階までの放電全体のシミュレーションを可能にする。本論文は、この最終目標に向けたETSの現状を提示する。これは、ワークフローの設計、不純物ソルバーの例におけるその構成要素の検証と妥当性確認について論じ、乱流輸送のための局所ジャイロ流体モデルとETSとの原理実証的結合を実証する。また、ITER類似壁を備えたJETトカマク放電へのETSの適用に関する最初の結果を提示する。これは、不純物からの放射と、ソースおよび輸送係数の選択との相関関係を研究する。
