Here is an analysis comparing conventional fission and proposed tokamak fusion reactors, published by Los Alamos:
https://www.lenr-canr.org/acrobat/KrakowskiRlessonslea.pdf Abstract Lessons from the four-year ARIES (Advanced Reactor Innovation and Evaluation Study) investigation of four magnetic-fusion-energy (MFE) power-plant embodiments of the tokamak are summarized. These lessons are derived from the physics; engineering and technology; economics; and environmental, safety, and health (ES&H) characteristics of these conceptual tokamak power-plant designs. This summary of ARIES lessons is intended to provide a general indicator of the requirements of economically and environmentally attractive fusion power. The integration of fundamental tokamak physics with conceptual engineering models through a cost-based systems methodology has been especially thorough in ARIES. The resulting quantitative tradeoffs among tokamak plasma physics, plasma engineering, and a wide range of supporting reactor engineering disciplines, and the enhanced interdisciplinary understanding of the impact of constraints leading to optimal tokamak reactors are major contributions of the ARIES Project. . . .
