We received the instruction document*1 titled "Submission request for the
report on the Accident Operation Manuals of Units 1 to 3 at Fukushima
Daiichi Nuclear Power Station" from the Nuclear and Industrial Safety
Agency (NISA) of the Ministry of Economy, Trade and Industry.
                                    (Previously announced on September 27)

                                    (Previously announced on September 28)

Per the instructions on September 27, we have organized materials
regarding information contained in the Accident Operations Manual of Unit

                                       (Previously announced on October 4)

Per the instructions on September 28, we have also organized materials

*4 Extension of the deadline
The instruction document on September 28 originally instructs us to report
them to NISA before October 4.  However, we asked NISA to extend the
deadline on October 4 as we had estimated that to organize those materials
would take plenty of time.  As a result, NISA accepted our request and the
new deadline was set on October 7. 

We have provided a Japanese press release version of the instruction
document received from NISA. However, at this time we have reserved the
right not to provide an English version due to potential misunderstandings
that may arise from an inaccurate rendering of the original Japanese text.
We may provide the English translation that NISA releases in our press
releases. However, in principle we would advise you to visit the NISA
website for timely and accurate information.
