Establishment of Toso Mirai Technology Co., Ltd. for Fuel Debris Retrieval at Fukushima Daiichi Nuclear Power Station
Tokyo Electric Power Company Holdings, Inc. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Tomoaki Kobayakawa; hereinafter referred to as “TEPCO”) and IHI Corporation (Headquarters: Koto-ku, Tokyo; Representative Director) President: Hiroshi Ide (hereafter referred to as “IHI”) has already announced that in April this year, the joint venture for fuel debris retrieval from the Fukushima Daiichi Nuclear Power Station will be established in October this year. We have agreed to establish After that, the two companies conducted detailed discussions, and today established a joint venture, Toso Mirai Technology Co., Ltd. (President: Masumi Ishikawa, hereinafter referred to as “Decom.Tech”). We are pleased to inform you that we have. Decom.Tech will organize the basic design of the systems and equipment required for further expansion of the scale of fuel debris retrieval (hereafter, large-scale retrieval), and will also be responsible for the research and development necessary for fuel debris retrieval. Looking ahead to the large-scale retrieval planned for the 2030s, we will expand the business step by step in line with business development and contribute to the safe and steady decommissioning work.
TEPCO is working on investigations inside the reactor containment vessel and preparations for trial removal in order to realize the decommissioning work process indicated in the “Decommissioning Medium- to Long-term Execution Plan 2022”. By establishing Decom.Tech this time, we have realized the construction of the systems and equipment necessary for large-scale retrieval. We will also contribute to the reconstruction of Fukushima.
IHI will make use of its experience as a nuclear reactor manufacturer, as well as its technology for remote handling under high radiation levels and the processing and storage of high-dose waste cultivated through the construction of spent fuel reprocessing facilities, to develop a safe and secure system for large-scale retrieval. We will contribute to the construction of facilities and systems that meet the needs of the site.
Going forward, TEPCO and IHI will use Decom.Tech to manage engineering and research and development in an integrated manner, and accelerate the improvement of project risk management functions. We will carry out debris retrieval safely and steadily, aiming to complete long-term decommissioning.
