Video: Dismantling of Unit 1 cover panels for spent fuel removal at Fukushima Daiichi Nuclear Power Station

Dismantling of Unit 1 cover panels for spent fuel removal

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.

Preventing Recriticality in Fuel Debris at Fukushima Daiichi Nuclear Power Station

This video will explain the conditions of the fuel retained in the reactors of Units 1-3 at Fukushima Daiichi Nuclear Power Station, and TEPCO's measures to prevent recriticality-return to a point at which a nuclear reaction becomes self-sustaining- in the fuel debris there.

Application of Robot Technology

The current situation at Fukushima Daiichi NPS–From 3.11 toward the future

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.
