As for the unit 4, we have been conducting internal inspections of 
the low-pressure turbine (A) by opening its cover since Nov.8th.

While conducting the inspections rotor blades and stator blades 
(the ninth and tenth), we found wear (maximum about 4mm) at the 
edges of the rotor blades (shrouds of the ninth and tenth) at 
around 4:40 pm on Nov.19th. We suppose that this wear was caused 
by contact of the rotor blades and the stator blades. We also 
found another wear (maximum about 2mm), which was also supposed 
to be made by contact, at the base of the ninth rotor blade and 
a stator blade. 

We will consider exchanging the edges of the rotor blades and 
repairing their bases. In addition, we will continue to inspect 
the rest of both blades (from the 11th to the 17th) of the 
low-pressure turbine and those of the high-pressure turbine.
Status and details of the inspections will be announced.
