About this website

We are committed to dealing with the accident at Fukushima Daiichi Nuclear Power Station and tackling the various issues in its aftermath, applying technologies and know-how gained from inside and outside Japan, in order to realize the plant's decommissioning.

"The current situation at Fukushima Daiichi NPS"

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

Fukushima Daiichi Nuclear Power Station was attacked by a huge tsunami caused by Tohoku Pacific Ocean earthquake on March 11 2011.

We would like to show you the latest situation of Fukushima Daiichi, looking back the time of the accident.

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.

Groundwater pump-up by Subdrain or Groundwater drain (plan)

The subdrain system, a group of wells, prevents groundwater from entering the reactor and turbine buildings and stops highly contaminated water generated. In order to prevent marine pollution, we are planning to operate another group of wells (groundwater drain) in the bank protection area and to close the sea-side impermeable walls along with the subdrain operation.

The pumped-up water is confirmed of its quality to meet the strict standard and then drained into the ocean, improving the quality of sea water in the harbors.

The purified water will be only discharged with the agreement of the relevant governments and local fishermen.
