Below is major impact to TEPCO's facilities due to the Miyagiken-Oki
Earthquake that occurred yesterday at 2:46PM.
*new items are underlined
[Nuclear Power Station]
Fukushima Daiichi Nuclear Power Station:
Units 1 to 3: shutdown due to earthquake
Units 4 to 6: outage due to regular inspection
* The national government has instructed evacuation for those local
residents within 10km# radius of the periphery (#as of 7:11PM, it has
expanded to 20km).
* The value of radioactive material (iodine, etc) is increasing according
to the monitoring car at the site (outside of the site). One of the
monitoring posts is also indicating higher than normal level.
* Since the amount of radiation at the boundary of the site exceeds
the limits, we decide at 4:17PM and we have reported and/or noticed
the government agencies concerned to apply the clause 1 of the Article 15
of the Radiation Disaster Measure at 5PM.
* In addition, a vertical earthquake hit the site and big explosion has
happened near the Unit 1 and smoke breaks out around 3:36PM.
Our two employees and two cooperation workers who had been working for
the foundation of safety are suffered and they are all sent to
the hospital.
* We continue endeavoring to secure the safety that all we can do and
monitoring the periphery.
Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to earthquake
* The national government has instructed evacuation for those local
residents within 10km radius of the periphery.
* At present, we have decided to prepare implementing measures to reduce
the pressure of the reactor containment vessel (partial discharge of air
containing radioactive materials) in order to fully secure safety.
These measures are considered to be implemented in Units 1, 2 and 3 and
accordingly, we have reported and/or noticed the government agencies
concerned.
* Unit 3 has been stopped and being “nuclear reactor cooling hot stop”
at 12:15PM.
* The operator seriously injured in the operating room of tower crane of
exhaust stack was transferred to the ground at 5:13PM and confirmed
the death at 5:17PM.
Kashiwazaki Kariwa Nuclear Power Station:
Units 1, 5, 6, 7: normal operation
Units 2 to 4: outage due to regular inspection
[Thermal Power Station]
Hirono Thermal Power Station Units 2 and 4: shutdown due to earthquake
Hitachinaka Thermal Power Station Unit 1: shutdown due to earthquake
Kashima Thermal Power Station Units 2, 3, 5, 6: shutdown due to
earthquake
Ohi Thermal Power Station Units 2, 3: shutdown due to earthquake
Higashi-Ohgishima Thermal Power Station Unit 1: shutdown due to
earthquake
[Hydro Power Station]
* All the stations have been restored.
[Transmission System, etc.]

[Supply and Demand Status within TEPCO's Service Area to Secure Stable
Power Supply]
Backup supply from Shinshinano Conversion Station: 600MW
Backup supply from Sakuma Conversion Station: 300MW
Backup supply from Higashi Shimizu Conversion Station: 100MW
Because TEPCO's facilities have been seriously damaged, power shortage
may occur. TEPCO appreciates customers' cooperation in reducing
electricity usage by avoiding using unnecessary lighting and electrical
equipment.
We are taking all measures to restore power, however, we expect extremely
difficult situation in power supply for tomorrow as well.
We kindly ask our customers to cooperate with us in reducing usage
of power.
Please do NOT touch cut-off electric wires.
* Revised past progress
