Environmental and economic assessments of magnetic and inertial fusion energy reactors

K. Yamazaki, T. Oishi, K. Mori2011年被引用 6Nuclear FusionIF 3出版社

Global warming due to rapid greenhouse gas (GHG) emissions is one of the present-day crucial problems, and fusion reactors are expected to be abundant electric power generation systems to reduce human GHG emission amounts. To search for an environmental-friendly and economical fusion reactor system, comparative system studies have been done for several magnetic fusion energy reactors, and have been extended to include inertial fusion energy reactors. We clarify new scaling formulae for the cost of electricity and GHG emission rate with respect to key design parameters, which might be helpful in making a strategy for fusion research development. Comparisons with other conventional electric power generation systems are carried out taking into account the introduction of GHG taxes and the application of the carbon dioxide capture and storage system to fossil power generators.

地球温暖化は、急速な温室効果ガス(GHG)排出による現代の重大な問題の一つであり、核融合炉は、人類のGHG排出量を削減するための豊富な発電システムとして期待されている。環境に優しく経済的な核融合炉システムを探索するため、複数の磁場閉じ込め核融合炉を対象とした比較システム研究が実施され、さらに慣性核融合炉も対象に拡張された。我々は、主要な設計パラメータに関する発電コストとGHG排出率の新しいスケーリング式を明らかにした。これは、核融合研究開発の戦略立案に有用であると考えられる。また、GHG税の導入と化石燃料発電への二酸化炭素回収・貯蔵(CCS)システムの適用を考慮した上で、他の従来型発電システムとの比較も実施した。
