Muon measuring instrument production for “muon transmission method” and its review by international experts
Jan.20,2015
Work on the construction of measuring equipment in preparation for testing of muon technology is currently underway. It is hoped that this technology will allow experts to obtain a view inside the reactors at the Fukushima Daiichi Nuclear Power Station (NPS).
To investigate the position of fuel in reactor using cosmic ray muon, a preparatory test for designing a measuring system was conducted at Fukushima Daiichi Nuclear Power Station.

IRID conducted a preparatory test for designing a measuring system using “muon transmission method” at Fukushima Daiichi Nuclear Power Station (NPS) and reports the result herein.
Progress status of “PCV lower-section repair technology” test
May.30,2014
The investigation and repair of primary containment vessel (PCV) leak locations are indispensable for water filling according to the fuel debris retrieval plan in the “Mid- and-Long-Term Roadmap” and for preventing contaminated water levels from increasing.
The progress status of the R&D project for the “inspection/repair of leaking locations using PCV lower-section repair technology” in the subsidy project of the Japanese Ministry of Economy, Trade and Industry (METI) is as follows:
Ongoing Development of “Submergible Crawling Swimming Robot” and “Shape-changing Robot”
Apr.24,2014
Hitachi-GE Nuclear Energy Ltd. (a member of IRID) and Hitachi Ltd. announced the development of two types of transformer robots that can modify their posture or shape in water or in narrow spaces surrounded by obstacles. These robots will advance to demonstration testing for IRID’s R&D projects, which has following main aims, namely “Inspection of leaking locations of the PCV” and “Investigating the inside of reactor containment vessels. This project is partially funded by the Japanese Ministry of Economy, Trade and Industry (METI).
“MEISTeR” Remote Control Robot Completes Demonstration Testing at Fukushima Daiichi Nuclear Power Station
Mar.25,2014
The “MHI-MEISTeR”, a remotely controlled robot developed by Mitsubishi Heavy Industries, Ltd. (MHI) funded by the Japanese Ministry of Economy, Trade and Industry (METI) has completed demonstration testing, and performed decontamination work and concrete core sampling tasks at the Fukushima Daiichi Nuclear Power Station (NPS).
