This issue is positioned as a special issue of the GPI Journal, and will be published by the GPI Standards Committee as a record booklet for the presentation of the symposium on the geological disposal of radioactive waste.
In holding this symposium, we received the efforts of the Japan Atomic Energy Relation Organization in all aspects, from the invitation of lecturers to the publication of this booklet. We also thank the Global Urban Business Society for their efforts in setting up the remote conference network.
We hope that this journal will continue to contribute widely to the development of technology for composite materials as a whole, and to benefit the world and people.
