Energetic and economic balance for an inertial fusion power plant

Nicola Cerullo, Salvatore Lanza, Marco Vezzani1995年Fusion Engineering and DesignIF 1.7出版社

AbstractStarting from the energetic diagram of a possible inertial fusion nuclear power plant, the energy balance is analysed as a function of the component energetic parameters, then the thermonuclear energy gain in the fusion chamber versus the recycling energy fraction and the driver efficiency is calculated. A new method for evaluating energetic and economic gain conditions which must be satisfied to design an efficient inertial fusion nuclear power plant is proposed. These conditions are strongly dependent on the values assumed by the recycling energy fraction used to feed the power plant. A simple expression was obtained for the recycling energy fraction, taking into account the construction, operating and dismantling costs of an IFC nuclear power plant. By this approach, a correlation among the various energetic and economic parameters was found, which, starting from the results obtained up to the present, leads to the identification of future research targets. The original mathematical model developed will allow the energetic and economic criteria to perform a comparative analysis of both current and planned inertial fusion experiments to be identified, in order to evaluate those which, at present, seem the most promising solutions for future ICF nuclear power plants.

抽象: 慣性核融合のエネルギー収支解析から出発し、可能な慣性核融合発電所の設計パラメータを検討した。エネルギー収支は、熱核燃焼パラメータとリサイクリング率に依存する関数として解析される。次に、熱核エネルギー利得とリサイクリング率の関係を、発電所の観点から検討した。建設費、運転費、廃止措置費を含む発電コストを考慮した経済性評価が行われる。慣性核融合発電所の設計パラメータを最適化するための方法論が提示される。この方法論は、現在の実験データと将来の炉心設計に適用される。結果は、慣性核融合発電所の実現可能性と経済的競争力を評価するために使用される。最後に、今後の研究開発の方向性が議論される。
