Hiroyasu Utoh, Senior Researcher in Fusion Energy Research and Development Directorate received the 21st JSPF Academic Award for Early Career Research Contributions
Award title
Construction of DEMO reactor remote maintenance scheme based on electromagnetic structural analysis
Description of the award-winning work
Blankets for functions including breeding tritium for fuel and divertor modules for removing heat need to be replaced regularly and maintained remotely in a DEMO reactor.
The remote maintenance scheme is one of the critical issues in the DEMO design, because it makes significant influence not only on the availability of the reactor but also on the design of superconducting magnets and in-vessel components for improved performance of the core plasma.
Hiroyasu Utoh, a Senior Researcher, set the following as evaluation criteria for the remote maintenance replacement schemes: (1) stabilization of the fusion plasma, (2) equilibrium controllability of the fusion plasma, (3) design of toroidal field coils. He has established potential concepts of in-vessel components and remote maintenance compatible with fusion plasma operation and the design of superconducting magnets based on multifaceted electromagnetic structural analyses and evaluation.
Comment
The construction of remote maintenance scheme, the award-winning subject, encompasses the whole DEMO reactor design, and is a culmination of collaboration and advice from the members of Fusion Reactor Design-Group as well as participants of the BA DEMO Design Activities and the DEMO Design Joint Special Team. I would like to take this opportunity to express my gratitude all of them. This award has given me a good incentive to continue my efforts for realization of the DEMO reactor. I would greatly appreciate your continuous supports.
