Integrated predictive modelling simulations of burning plasma experiment designs

Glenn Bateman, Thawatchai Onjun, Arnold H Kritz2003年Plasma Physics and Controlled FusionIF 2.2出版社

Models for the height of the pedestal at the edge of H-mode plasmas (Onjun T et al 2002 Phys. Plasmas9 5018) are used together with the Multi-Mode core transport model (Bateman G et al 1998 Phys. Plasmas5 1793) in the BALDUR integrated predictive modelling code to predict the performance of the ITER (Aymar A et al 2002 Plasma Phys. Control. Fusion44 519), FIRE (Meade D M et al 2001 Fusion Technol.39 336), and IGNITOR (Coppi B et al 2001 Nucl. Fusion41 1253) fusion reactor designs. The simulation protocol used in this paper is tested by comparing predicted temperature and density profiles against experimental data from 33 H-mode discharges in the JET (Rebut P H et al 1985 Nucl. Fusion25 1011) and DIII-D (Luxon J L et al 1985 Fusion Technol.8 441) tokamaks. The sensitivities of the predictions are evaluated for the burning plasma experimental designs by using variations of the pedestal temperature model that are one standard deviation above and below the standard model. Simulations of the fusion reactor designs are carried out for scans in which the plasma density and auxiliary heating power are varied.

Hモードプラズマのペデスタル高さに関するモデル(Onjun Tら 2002 Phys. Plasmas9 5018)を、マルチモードコア輸送モデル(Bateman Gら 1998 Phys. Plasmas5 1793)とともにBALDR統合予測コードで用いて、ITER(Aymar Aら 2002 Plasma Phys. Control. Fusion44 519)、FIRE(Meade D Mら 2001 Fusion Technol.39 336)、およびIGNITOR(Coppi Bら 2001 Nucl. Fusion41 1253)の核融合炉設計の性能を予測する。本論文で用いるシミュレーションプロトコルは、JET(Rebut P Hら 1985 Nucl. Fusion25 1011)およびDIII-D(Luxon J Lら 1985 Fusion Technol.8 441)トカマクにおける33回のHモード放電の実験データと予測された温度・密度分布を比較することにより検証する。燃焼プラズマ実験設計に対する予測の感度は、ペデスタル温度モデルの標準モデルから1標準偏差上下の変動を用いて評価する。核融合炉設計のシミュレーションは、プラズマ密度と補助加熱出力を変化させたスキャンに対して実施する。
