Development of decontamination equipment for upper floors of the reactor building at the Fukushima Daiichi Nuclear Power Station (Dec.16, 2015)
Dec.16,2015
IRID is developing decontamination equipment for upper floors—a new robot for decontaminating the second and third floors of the reactor building at the Fukushima Daiichi Nuclear Power Station (NPS).
[Videos] Operations Training for Investigation inside the Primary Containment Vessel (PCV) at the Fukushima Daiichi Nuclear Power Station (NPS) Unit 2 and Equipment for Preliminary Investigation inside the Pedestal and Deposit Removal Equipment (Oct. 14, 2015)

The inside of the PCV at the Fukushima Daiichi NPS Unit 2 is to be investigated by deploying the remotely-operated robot (scorpion robot) in place as soon as on-site preparations are completed, including investigation of the periphery of the penetration through which the investigation robot will be inserted.
Below are five videos, including one showing TOSHIBA CORPORATION, an IRID member, conducting training in preparation for the investigation inside the PCV this summer.
Development and Utilization of Dry Ice Blast Decontamination Equipment for High Places (Sept. 8, 2015)

The decontamination work in reactor buildings at the Fukushima Daiichi Nuclear Power Station (NPS) must be accelerated as early as possible because radiation doses there are currently high and therefor workers are not able to put in long hours.

IRID plans to use a miniature robot to investigate (‘A2 Investigation’) the inside of the Fukushima Daiichi Unit 2 primary containment vessel (PCV). This investigation will see the robot make its way the point directly below the reactor pressure vessel and making full use of an onboard camera, in addition to other devices, measure radiation and temperature levels and have it collect vital data for the consideration of various decommissioning scenarios.
Commencement of Reactor Interior Survey Using ‘Muon Transmission Method’ (February 12, 2015)
Feb.12,2015
A survey of the interior of Unit 1 at the Fukushima Daiichi Nuclear Power Station (NPS) using the ‘muon transmission method’ began on February 12, 2015.
In order for the decommissioning of the damaged reactors at the Fukushima Daiichi NPS to proceed, molten fuel debris inside the reactors must first be retrieved. However, radiation levels are extremely high, preventing workers from entering the reactor building and directly observing the condition and location of the fuel in the cores.
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).
