other• In the Unit 1, 2, 3 and 4, which automatically shut down due to 
       the Tohoku-Chihou-Taiheiyo-Oki Earthquake on March 11th, 2011, 
       we had been preparing measures for decreasing the pressure of 
       each reactor containment vessel since March 12th. However, on 
       March 17th, we released such preparation in all of the Units.
