Impact to TEPCO's Facilities due to Miyagiken-Oki Earthquake (as of 8AM)
Below is major impact to TEPCO's facilities due to the Miyagiken-Oki
Earthquake that occurred yesterday at 2:46PM.
*new items are underlined
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 20km radius of the site periphery.
* 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, Mar 12 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, Mar 12.
* In addition, a vertical earthquake hit the site and big explosion has
happened near the Unit 1 and smoke breaks out around 3:36PM, Mar 12th.
* We started injection of sea water into the reactor core of Unit 1 at
8:20PM, Mar 12 and then boric acid subsequently.
* High Pressure Coolant Injection System of Unit 3 automatically stopped.
We endeavored to restart the Reactor Core Isolation Cooling System but
failed. Also, we could not confirm the water inflow of Emergency Core
Cooling System. As such, we decided at 5.10AM, Mar 12, and we reported
and/or noticed the government agencies concerned to apply the clause 1 of
the Article 15 of the Radiation Disaster Measure at 5:58AM, Mar 13.
In order to fully secure safety, we operated the vent valve to reduce the
pressure of the reactor containment vessels (partial release of air
containing radioactive materials) and completed the procedure at 8:41AM,
Mar 13,
* 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 trapped in the crane operating console of the 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
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
* All the stations have been restored.
4 substations shown below have been shutdown:
- Naka Substation
- Shin Motegi Substation
- Joban Substation
- Ibaraki Substation
- Nishi Mito Substation
Total of about 0.31 million households are out of power.
Tokyo: 0
Kanagawa Pref.: 0
Tochigi Pref.: 7,221
Chiba Pref.: 301
Saitama Pref: 0
Gunma Pref.: 0
Ibaraki Pref: 298,977
Yamanashi Pref: 0
Shizuoka Pref: 0 (east of Fuji River)
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.
