Currently, a large quantity of radioactive wastewater exists inside the
turbine building of Fukushima Daiichi Nuclear Power Station. In this
regard, on April 10th, we received a direction from Minister of Economy,
Trade and Industry to report on matters in connection with transfer of
high level radioactive wastewater to the Centralized Radiation Waste
Treatment Facility, such as necessity, assessment of safety, plans on
permanent safety storage of wastewater and treatment facilities.
(Previously announced on April 15th, 2011)
Since we completed implementing measures to prevent leakage in the main
process building of the Centralized Radiation Waste Treatment Facility,
we compiled the details based on the direction given and reported to
Minister of Economy, Trade and Industry on April 18th, 2011. Concurrently,
the content of the report has been confirmed by Nuclear and Industrial
Safety Agency.

From April 19th, 2011, we have been continuously transferring high
radioactive wastewater from the turbine building of Unit 2 to the Process
Main Building of the Centralized Radiation Waste Treatment Facility.
Since the level of radioactive wastewater in the turbine building of Unit
3 is increasing, we have been implementing prevention of leakage in the
Miscellaneous Solid Waste Volume Reduction Treatment Building of the
Centralized Radiation Waste Treatment Facility. As the prevention work in
the misc solid waste capacity reduction facility is completed, we compiled
the details based on the direction given and reported to Minister of
Economy, Trade and Industry. The content of the report has been confirmed
by Nuclear and Industrial Safety Agency.
Based on the method described in the report, we will start transferring
high level radioactive wastewater from the turbine building of Unit 3 to
the Centralized Radiation Waste Treatment Facility once we complete
preparation.
