Message from the President

Technology Research Association, International Research Institute for Nuclear Decommissioning Hideo ishibashi, PresidentSince its establishment in August 2013 the International Research Institute for Nuclear Decommissioning (IRID) has been fully committed to an urgent challenge: Research and Development (R&D) of the technologies required in the decommissioning of the Fukushima Daiichi Nuclear Power Station (NPS). In August 2014, the Nuclear Damage Liability Facilitation Fund was reorganized as the Nuclear Damage Compensation and Decommissioning Facilitation Corporation (NDF). The division of roles among the relevant organizations engaging in the decommissioning was then clarified: The NDF formulates strategies and R&D plans for the decommissioning; The Tokyo Electric Power Company (TEPCO) implements on-site operations; and IRID conducts R&D of the technology required in the decommissioning work. The four key players, including the government, have been working closely together in the effort to decommission the Fukushima Daiichi NPS.

This has resulted in the development of technology for investigating inside the primary containment vessel and the development of technology for identifying fuel debris using cosmic rays, and thus the situation inside the Primary Containment Vessel (PCV) has become clearer while the technological challenges that have to be overcome have also become clearer.

The Mid-and-Long-Term Roadmap was revised by the government after reflecting a revision of the “Technical Strategic Plan 2017 for Decommissioning of the Fukushima Daiichi NPS of TEPCO Holdings, Ltd.” (Strategic Plan 2017, hereinafter) made by NDF, which provides the technological basis for the NDF Mid-and-Long-Term Roadmap for Decommissioning of the Fukushima Daiichi NPS of TEPCO Holdings, Ltd. (Mid-and-Long-Term Roadmap, hereinafter) in September 2017.

It expressed that the policy with fuel debris retrieval should focus on the partial submersion side access method and retrieval of debris from the bottom of the PCV, and that the fuel debris retrieval method for an initial unit will be determined in FY 2019. R&D on the fuel debris retrieval is therefore about to enter a crucial phase.

In ensuring safe and secure decommissioning of the Fukushima Daiichi NPS, the IRID is committed to the responsibility of making steady achievements in R&D with respect to the reconstruction of Fukushima, and amassing knowledge from all over the world. Furthermore, IRID would like to contribute to the next generations through the R&D we are involved in.

We sincerely appreciate your kind guidance, continued support, and encouragement.
