In a collaborative effort, TEPCO, Toshiba, and IRID developed a "Scorpion-shaped robot" to investigate conditions of the melted-down fuel debris and the Unit 2 Primary Containment Vessel (PCV) at Fukushima Daiichi Nuclear Power Station. It would be a significant step forward in the decommissioning work to obtain any information from the PCV, such as digital images, temperature data, and radiation levels. This video introduces the challenges for this robot as well as the commitment of Toshiba engineer Takayuki Nakahara who deals with this very challenging mission.
This video shows various measures against dust dispersion during the dismantling work of cover panels over Unit 1 reactor building. At Unit 1, rubble from the damaged building caused by the hydrogen explosion is still scattered and needs to be removed. Cover panels were placed over the rubble to prevent the dispersion of radioactive materials, but dismantling of the panels started in July 2015 to remove the rubble. Wall pannels will be taken down around September 2016.
We have created a new web content featuring ROBOTS applied to decommissioning operations. This page introduces robot applications inside the reactor buildings, which have been disclosed chronologically in our web site, with pictures, videos, and documents.
With support and cooperation of both domestic and international corporations and organizations, robots has been applied to the operations, such as the decontamination of the high-dose radiation area and the removal of fuel debris, and contributed to the reduction of operational risk of radiation exposure.
