Indirectly driven target design influence on energetic balance of inertial confinement fusion power plant

N. Cerullo, S. Lanza, M. Vezzani1998年Fusion Engineering and DesignIF 1.7出版社

AbstractA detailed energy flow diagram for indirect drive ICF was elaborated. Using driver pulse energy as input, this diagram undergoes various energy processes of conversion, absorption, re-emission and transfer, until the thermonuclear energy delivered by target fusion is reached as output. Each process was identified with an energetic parameter (efficiency or gain). Starting from this diagram it was possible to analyse the influence of each energetic parameter on the energetic balance of ICF power plant. In this paper special attention was put on the influence of target design (materials and dimensions) on the transfer efficiency and on capsule illumination uniformity. The analysis led to the evaluation of optimal target materials and dimensions to achieve a positive energetic balance of an ICF power plant.

間接駆動ICFの詳細なエネルギーフロー図を作成した。この図は、ドライバーパルスエネルギーを入力とし、変換、吸収、再放射、伝達といった様々なエネルギー過程を経て、最終的にターゲット核融合によって放出される熱核エネルギーを出力とするものである。各過程は、エネルギー効率または利得というエネルギー学的パラメータに対応付けられた。このフローダイアグラムに基づき、各エネルギー学的パラメータがICF発電所のエネルギー収支に及ぼす影響を分析することが可能となった。本論文では、特にターゲット設計(材料と寸法)が伝達効率とカプセル照射均一性に及ぼす影響に着目した。この分析により、ICF発電所の正のエネルギー収支を達成するための最適なターゲット材料と寸法の評価が導かれた。
