At 2:48PM on March 11th, turbines and reactors of Tokyo Electric Power 
Company's Fukushima Daiichi Nuclear Power Station Unit 1 (Boiling Water 
Reactor, rated output 460 Megawatts) and Units 2 and 3 (Boiling Water 
Reactor, Rated Output 784 Megawatts) that had been operating at rated 
power automatically shutdown due to the Miyagiken-oki Earthquake.
 
After the shut down, the values of radioactive materials (iodine, etc) 
measured by the monitoring car have been increasing. Increase in the 
measured value has also been recognized in one of the monitoring posts.

Furthermore, at 3:29PM, Mar 12, radiation dose measured at site boundary 
has exceeded the limiting value. Therefore, at 4:17PM, Mar 12, it was 
determined that a specific incident stipulated in article 15, clause 1 
has occurred.

                                     (as per the previous press release)

After that, the radiation dose at the monitoring post decreased once. 
Today, the measured value revamped and the radiation dose measured at 
site boundary exceeded the limiting value again. As such, at 8:56AM, 
today, it was determined that a specific incident stipulated in article 
15, clause 1 occurred. 

We will endeavor to secure the safety and alongside, continue monitoring 
the environment of the site periphery.
