Message from the President
Ever since establishment in August 2013, the International Research Institute for Nuclear Decommissioning (IRID) has focused on strengthening the platform for nuclear decommissioning technology, undertaking R&D on the technologies necessary to decommission the Fukushima Daiichi Nuclear Power Station (NPS), which is an urgent issue at present. In August 2014, the Nuclear Damage Liability Facilitation Fund was restructured as the Nuclear Damage Compensation and Decommissioning Facilities Corporation (NDF). With this restructuring, the decommissioning scope has been clearly defined: NDF develops decommissioning strategy and R&D plans, Tokyo Electric Power Company Holdings, Inc. (TEPCO) undertakes onsite work, and IRID implements the R&D for technologies required for decommissioning. The four key players, including the government, have been closely working together in the process of decommissioning the Fukushima Daiichi NPS.
As a result, the conditions of the nuclear reactor and the primary containment vessel (PCV) interiors have been clarified by development of technologies for investigating inside the PCV and for utilizing cosmic rays to detect the position of fuel debris, while the technical issues that ought to be overcome have been also identified.
This decommissioning work is being undertaken in accordance with the “Technical Strategic Plan for Decommissioning of the Fukushima Daiichi NPS of TEPCO Holdings, Inc.”, published by NDF, which provides the technological basis for the Mid-and-Long-Term Roadmap for Decommissioning of the Fukushima Daiichi NPS of TEPCO Holdings, Inc., (Mid-and-Long-Term Roadmap, hereinafter). This prioritizes the task of retrieving fuel debris from the PCV bottom, focusing on the partial-submersion side-access method, as a fuel debris retrieval policy. In accordance with the government and the NDF policy, IRID is dedicated to R&D toward achievements in technology for more detailed investigation inside the PCV and for fuel debris retrieval.
In ensuring the safe decommissioning of the Fukushima Daiichi NPS, 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 involvement of future generations through R&D.
We sincerely appreciate your kind guidance, continued support, and encouragement.
