Press Release (May 13,2011)
Commencement of a preparation work for the installation of a cover for the reactor building of Unit 1, Fukushima Daiichi Nuclear Power Station
In accordance with "Roadmap towards Restoration from the Accident at 
Fukushima Daiichi Nuclear Power Station" published on April 17th, 2011, we
will commence a preparation work from May 13th for the installation of a 
cover for the reactor building of Unit 1, Fukushima Daiichi Nuclear Power 
Station to prevent the diffusion of radioactive substances.

This cover for the reactor building will be installed as an emergency 
measure to prevent the diffusion of radioactive substances until 
mid-to-long term measures including radiation shielding are implemented.
In the installation work of the cover, moreover, we are now considering 
utilizing crawler cranes (i.e. large heavy machineries) in order to 
minimize the exposure dose of the workers and shorten the work period.
Prior to the installation work of the cover for the reactor building, we 
have decided to commence the preparation work from May 13th, including 
flattening the ground to bring crawler cranes into the site.

■ Schedule
 We plan to start the installation of the cover for the reactor building 
 from June.
