The Tokyo Electric Power Company has made a decision to shut down Unit 4 of
Kashima Thermal Power Station due to potential risks of combustion gas
leakage expansion and pending repair work (Manager: Masakuni ARAKI,
Address: Higashi-Wada 9, Kamisu-shi, Ibaraki, Rated output: 600MW). This
will be effective from 10pm on July 27, 2011.
As we discovered trace amounts of combustion gas leaking from the boiler
unit during an equipment inspection conducted on July 9, we continued
operations under enhanced monitoring conditions to verify operational
safety. Nevertheless, after ascertaining the distinct possibility of a leak
expansion, we have decided to undergo repairs to secure future power
supplies.
We will restart the unit on August 6, 2011.
