Organizations Worldwide
・Fuel debris retrieval and decommissioning of Fukushima Daiichi NPS
is unprecedented technological challenge the world has ever faced.
We need to promote alliance and cooperation with relatedorganizations worldwide so as to establish a scheme enabling
integration of world knowledge.
・As for technological challenges with extreme difficulty such as fueldebris retrieval, we are considering ways to encourage wide varietyof ideas and proposals from worldwide.
〈Present plans〉
・Dissemination to world arena using occasions like IAEA general
assembly (the week of 9/16).
・Soliciting advices at International Experts Group meeting to be held inJapan during the week of 9/23.
・International collaborative project meeting of OECD/NEA for accident
analysis (10/15 to 17).

and Human Resource Development
・To secure human resource and its development from mid-to-long term perspective,
promote fundamental studies under alliance with universities, research institutes
and so forth.
・By hosting workshops, tied up with Ministry ofEducation, Culture, Sports, Science and Technology (MEXT), promote
dissemination and sharing information on R&D program, while considering areas
and tasks of fundamental studies to focus which meet practical needs.
〈Present plans〉
To host a series of workshops on R&D program and fundamental studies.
- 1st (9/25 Kanto-1): R/W and fuel debris related- 2nd (10/8 Fukushima): Development of remote controlled equipment and device,
Data visualization related-3rd (Around late October, Kansai/Western Japan-1): R/W, Fuel debris related-4th (Around Mid November, Tohoku/Hokkaido): Soundness of PCV etc., R/W related-For after 5th, planning to host at respective areas
