核融合発電所（Fusion power plant、fusion power plants）は、核融合・プラズマ物理学の工学。核融合反応のエネルギーを電気に変換する発電設備で、実験炉の次の段階として想定される実用炉の設計概念を指す。重水素－トリチウム燃料を用い、ブランケットでトリチウムを増殖し熱を取り出す。ダイバータの高熱負荷対策や安全性、放射性廃棄物管理が主要な工学的課題である。この用語集が追う論文のうち、タイトルにこの主題が現れるものは158本ある。比重が最も大きいのは直近の2025–2029年で、その期間に発表された論文の0.61%を占める。この用語集がこの主題を最初に拾うのは1995年以降で、それ以前の収録論文には現れない。
The block diagram shows the high-level fuel cycle of an ARC-class FPP. The outer fuel cycle (OFC) breeds tritium via Li(n), (T) reactions in the blanket and coolant channels. This tritium is passed to the inner fuel cycle (IFC), where it is processed into fuel. Only the components that have been modeled in this work are shown in the figure. The DIR system is represented by a dotted path to indicate that it may or may not be present in the IFC. The dotted path from the heat exchanger to the detritiation system is present if the chosen heat exchanger has an active tritium removal system (e.g. a double-walled heat exchanger with purge gas flow). The inclusion of DIR and the decision to include T extraction in the heat exchanger (HX) are examples of ARC design decisions which have yet to be finalized.
Indicative (not calculated) power flow for a tokamak power plant. Some concepts consider using the low-grade heat to improve the overall efficiency, e.g. for pre heating of heat transfer fluids, and potentially thermomechanical not electrical energy for some of the recirculating power (e.g. some classes of pump). For EU DEMO, Pfus is presently set around 2GW aiming at several hundred MW electricity output, in pulsed operation [2].
The capacity factor and recirculated power fraction determine the reduction of the plant efficiency according to equation (1). The shaded area represents the expectation values of fusion power plants based on the steady state tokamak concept, as estimated in sections 2 and 3 of this paper. Note how the combination of a high recirculated power and a modest capacity factor results in serious reduction of the overall plant efficiency. In contrast, with a low recirculated power, more typical of conventional power plants or renewable energy technologies, the plant efficiency does not depend on the capacity factor.
