Alternative divertor target concepts for next step fusion devices

I.V. Mazul2016年被引用 6Nuclear FusionIF 3出版社

The operational conditions of a divertor target in the next steps of fusion devices are more severe in comparison with ITER. The current divertor designs and technologies have a limited application concerning these conditions, and so new design concepts/technologies are required. The main reasons which practically prevent the use of the traditional motionless solid divertor target are analyzed. We describe several alternative divertor target concepts in this paper. The comparative analysis of these concepts (including the advantages and the drawbacks) is made and the prospects for their practical implementation are prioritized. The concept of the swept divertor target with a liquid metal interlayer between the moving armour and motionless heat-sink is presented in more detail. The critical issues of this design are listed and outlined, and the possible experiments are presented.

核融合装置の次の段階におけるダイバータ標的の運転条件は、ITERと比較してより厳しいものとなる。現在のダイバータ設計および技術は、これらの条件への適用が限られており、新たな設計概念・技術が要求される。従来の固定式固体ダイバータ標的の使用を実際的に妨げる主な理由を分析する。本論文では、いくつかの代替ダイバータ標的概念について述べる。これらの概念の比較分析(利点および欠点を含む)を行い、それらの実用化の見通しに優先順位を付ける。移動式アーマーと固定式ヒートシンクの間に液体金属中間層を有する掃引式ダイバータ標的概念について、より詳細に提示する。この設計の重要な課題を列挙して概説し、可能性のある実験を示す。
