Press Releases 2015

On June 9, 2011, we received an instruction document^*, "Installment of treatment facility and storing facility of water including highly concentrated radioactive materials at Fukushima Daiichi Nuclear Power Station (Instruction)" from Nuclear and Industrial Safety Agency (NISA) of Ministry of Economy, Trade and Industry.

(Previously announced on June 9, 2011)

Since then, per the instruction, we have been treating the water accumulated in the Central Radioactive Waste Treatment Facility that contains highly concentrated radioactive materials. We announce today we submitted a report to the Nuclear Regulation Authority regarding the latest updates of storage and treatment of the accumulated water.

*Attachment-1 and Attachment-2 of Storage and Treatment of High Level Radioactive Accumulated Water, 188th report, published on February 13, 2015, contain the following incorrect figures. We would like to apologize for providing those figures, and inform you of the correct ones in the announcement.

1. Storage and Treatment of High Level Radioactive Accumulated Water (as of February 12, 2015), Attachment-1
The table at the upper right corner of the Attachment-1 shows the “Storage volume” of different water storage tanks. The figure of the “Treated water storage tank” cell in there was 305,846m³ as first published, but the correct one is 306,896m³. As a result, the corresponding figure of the “Change from the last report” cell should be amended to +9,833m³.

2. Storage and Treatment of High Level Radioactive Accumulated Water (as of February 19, 2015), Attachment-2
The figure of the “Treated water storage tank” cell in the table of the “Storage volume” in the Attachmet-2 was 316,425m³ as first published, but the correct one is 317,475m³.
