In accordance with “Roadmap towards Restoration from the Accident at 
Fukushima Daiichi Nuclear Power Station”, we have decided to install 
a cover for the reactor building of Unit 1 of Fukushima Daiichi 
Nuclear Power Station in order to prevent the diffusion of 
radioactive substances and are going to commence main construction in 
the site on June 27th.
(Previously announced on May 13th and June 14th)

Today, from Nuclear and Industrial Safety Agency of Ministry of 
Economy, Trade and Industry (NISA), we have received an instruction 
document* entitled "Instruction to report on installing the reactor 
building cover and ancillary facilities for Unit 1 of Fukushima 
Daiichi Nuclear Power Station of Tokyo Electric Power Company"

Pursuant to this instruction, with regard to installation of the 
reactor building cover for Unit 1 of Fukushima Daiichi Nuclear Power 
Station, we will summarize the contents of the plan to install it and 
evaluation on the effect of decreasing the volume of radioactive 
substance emission and safety and will report them to NISA by June 
23rd.
