On June 22, 2011, we received an instruction document, from Nuclear and
Industrial Safety Agency (NISA), entitled "Instruction to submit reports
related to injection of nitrogen to the reactor containment vessel of Unit
2 at Fukushima Daiichi Nuclear Power Station". *
(Previously announced on June 22, 2011)
Subsequently, regarding the injection of nitrogen to the reactor
containment vessel of Unit 2 at Fukushima Daiichi Power Station, we have
compiled a report that we will start the injection as early as possible
after the preparation of necessary work environment and the environment
impact due to the injection is below the exposure dose limit (1mSv per
annum) to the general public, and have reported to NISA yesterday.

Instruction to submit reports related to injection of nitrogen to the
reactor containment vessel of Unit 2 at Fukushima Daiichi Nuclear Power
Station
We have provided a Japanese press release version of the instruction
document received from NISA. However, at this time we have reserved the
right to not 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.
