Key Field: Decommissioning

Technical Development with Domestic
and International Wisdom

To move forward with the decommissioning of the nuclear power plant, an initiative crucial to the reconstruction of the Hamadori area, the Framework draws upon domestic and international wisdom to promote research and development as well as human resource development, then spread the benefits of these efforts to the industrial sector as well to build an industrial cluster in the Hamadori area.

JAEA/Naraha Center for Remote Control
Technology Development (NARREC)

The Japan Atomic Energy Agency (JAEA) has been working to develop the technology required for decommissioning work. One such technology is a system that uses VR technology to replicate the sensation of being at the Fukushima Daiichi Nuclear Power Plant. This system makes it possible to conduct training and examine work plans inside the reactor.

JAEA/Okuma Analysis and Research Center

The Facility for Analysis and Research of Radioactive Materials consists of three buildings: the Administration Building, where staff members perform administrative work, then Laboratories 1 and 2, where analysis and research are conducted. Laboratory 1, which analyzes waste samples with medium to low radioactivity, commenced operations as a laboratory on June 24, 2022, after which it was used for experiments and analysis preparation, then, following the establishment of a controlled zone as part of the designated nuclear facility, analysis work on radioactive substances commenced. Detailed design and construction preparation is underway for Laboratory 2, which will analyze fuel debris and other substances.

JAEA/Collaborative Laboratories
for Advanced Decommissioning Science (CLADS)

This center builds integrated systems for promoting human resource development and R&D across industry, academia, and government while forming networks that enable the exchange of human resources from universities, research institutions, and industry in Japan and abroad to move forward with the decommissioning of the nuclear power plant.

Developing Technology for Application in Decommissioning Robot Systems

Able Co., Ltd.

Able Co., Ltd. (headquartered in the town of Okuma, Futaba District, Fukushima Prefecture) is using a remote-controlled robot system to dismantle the 120-meter-long exhaust stack at the Fukushima Daiichi Nuclear Power Plant. Using knowledge accumulated over many years, they have not only undertaken the practical work of decommissioning the nuclear reactor but have increasingly expanded the scope of robot use.

Fukushima Decommissioning Industry Business Exhibition

A new event involving contractors, research institutions, and other organizations both inside and outside Fukushima Prefecture called the Fukushima Decommissioning Industry Business Exhibition was hosted to create a space for business matching and promoting clustering of the decommissioning industry for local companies involved in decommissioning, and featured three events held on the same day: the 2nd Decommissioning Industry Exchange Meeting 2022, the Decommissioning and Disaster Response Robot Technology Exhibition and Demonstration, and the Fukushima Decommissioning Industry Business General Exhibition (November 8, 2022).

Developing Human Resources for Decommissioning

Creative Robot Contest for Decommissioning

An annual contest hosted every year since 2016 by the Ministry of Education, Culture, Sports, Science and Technology based on the Fukushima Innovation Coast Framework. This contest aims to spark interest in decommissioning the nuclear reactor and cultivate creativity among children by building a robot imagined for use in decommissioning work. The venue for this event is the Naraha Center for Remote Control Technology Development (Naraha, Fukushima) at the Japan Atomic Energy Agency (JAEA).
