Economic goals and requirements for competitive fusion energy

Ronald L. Miller1998年Fusion Engineering and DesignIF 1.7出版社

AbstractFuture economic competitiveness, coupled to and constrained by environmental and safety characteristics, continues to provide a central strategic motivation and concern for fusion research. Attention must also be paid to the evolving cost projections of future fusion competitors, with appropriate consideration of externalized impacts, insofar as they establish the eventual market-penetration context and also influence the near-term funding climate for fusion R&D. With concept optimization and selection in mind, tradeoffs among system power density, recirculating power, plant availability (reflecting both forced and planned outages), complexity, and structural materials and coolant choices are best monitored and resolved in the context of their impacts on capital and operating costs, which, together with low fuel costs and financial assumptions, determine the projected life-cycle product cost of fusion. Considerations deriving from deregulation and privatization are elucidated, as are possible implications of modern investment-analysis methods.

将来の経済的競争力は、環境特性と安全性の制約と結びつきつつ、核融合研究における中心的戦略的動機であり続けている。将来の核融合競合技術のコスト見通しの変遷にも注意を払う必要があり、外部性(外部コスト)の影響を適切に考慮しつつ、それらが最終的な市場普及の状況を左右し、また核融合研究開発(R&D)の短期的な資金環境にも影響を与える点を踏まえなければならない。概念の最適化と選択にあたっては、システム出力密度、再循環動力、プラント稼働率(計画停止および強制停止の両方を反映)、複雑性、構造材料と冷却材の選択の間のトレードオフを、資本コストと運転コストへの影響という観点から評価することが最も適切であり、これらは、低燃料コストや財務上の前提条件と相まって、核融合のライフサイクルコストを左右する。さらに、規制緩和と民営化に由来する考慮事項、ならびに現代の投資分析手法がもたらし得る影響についても明らかにする。
