Status of research and development conducted by the International Research Institute for Nuclear Decommissioning

Since the International Research Institute for Nuclear Decommissioning (IRID) was established as a technology research association in August 2013, it has been engaged in research and development (R&D) for decommissioning the Fukushima Daiichi nuclear power plant, which is currently an urgent issue, to strengthen the platform for decommissioning technology for the future. The work of IRID R&D is classified into three main pillars: removal of spent nuclear fuel from the pool; retrieval of fuel debris; and technological development for treatment and disposal of solid radioactive waste. This article describes an overview of R&D as of the first half of the fiscal year 2020, mainly focusing on investigation inside primary containment vessels and retrieval of fuel debris.

Positioning Time

Toshiba Corporation, a member of International Research Institute of Nuclear Decommissioning (IRID), has contributed to decontamination works throughout Fukushima Daiichi Nuclear Power Plant from outside ground to inside of the buildings. Speedy decontamination works allow workers to access and stay inside of the contaminated buildings for many hours, and as a result, all decommission works can be accelerated. Some remote decontamination machines to decontaminate the inside of the reactor buildings from a remote safe building have been developed for workers not to be radiated by high-level radiation. Conventionally, operators have remotely controlled the decontamination machine through multiple views of some remote surveillance cameras mounted on it. Because the position data such as GPS data is not available in the buildings, it was hard for operators to detect its absolute position and orientation in the building, and it took much time to recognize targets to be decontaminated. In order to reduce positioning time and make operation works easier, we constructed 3D positioning system to automatically detect the absolute 3D position of the decontamination machine in the reactor buildings from a remote safe building. Moreover, we can also keep records of decontamination works easily by tracking 3D position of the decontamination machine. This paper shows the overview of our approach of 3D positioning and a result of examinations in the mock-up facility that simulates a part of the inside of the reactor building at Fukushima Daiichi NPP.
