MS10 has strengthened its portfolio by newly selecting seven projects in FY2025. In selecting these new projects, we required them to address highly challenging research topics under the “breakthrough in one area, full-scale expansion” scenario, while also evaluating the clarity of their scientific and technological vision. With the recognition that the combination of “challenging nature” and a “clear vision” is what society expects from the Moonshot R&D Program, MS10 will conduct stage-gate evaluations through open discussions at all opportunities deemed necessary.

This workshop will examine the scientific and technological validity of the scenario for achieving the central objective of the Okada Project, “Innovative Muon-Catalyzed Fusion Technology for Practical Applications,” namely the achievement of a fusion number F ~ 1000. Muon-catalyzed fusion is a method in which nuclear fusion is induced by introducing muons into a mixed deuterium–tritium target, and it has the potential to be a game-changer as a fusion approach that does not require ultra-high-temperature plasma.
The fusion number F, an indicator of feasibility, refers to the number of nuclear fusion reactions mediated by a single muon during its lifetime of 2.2 microseconds. It is estimated that F ~ 1000 is required for muon-catalyzed fusion to become viable as an energy plant. The Okada Project aims to achieve F ~ 1000 by fully utilizing previously untapped elementary processes. This workshop will provide a forum to examine, from a cutting-edge scientific and technological perspective, the theoretical feasibility of this goal and methods for validating the reaction processes, and to discuss whether the project can identify a viable path to success toward the target. We sincerely invite your participation.
