Tokio Electric Power Company informa en detalle de la situación en la planta #nuclear de Fukushima: Nota de prensa.

Press Release (Mar 12,2011)
Impact to TEPCO's Facilities due to Miyagiken-Oki Earthquake (as of 3PM)

Nota de prensa de TEPCO, la compañía eléctrica de Tokio,  Central Nuclear Fukushima

 
Below is major impact to TEPCO's facilities due to the Miyagiken-Oki
Earthquake that occurred yesterday at .
*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.
* Measurement of radioactive material (Iodine, etc.) by monitoring car
indicates increasing value compared to normal level. One of the
monitoring posts is also indicating higher than normal level. We will
continue monitoring discharge of radioactive material from exhaust stack
and discharge canal, etc.
* Reactor of Unit 1 has been shut down and steam in reactor has been
cooled by isolation condenser, but it is now stopped. Because pressure
level in reactor containment vessel is increasing, following the national
government instruction, we have done the measure to reduce the pressure of
the reactor containment vessels in order to fully secure safety and we
understand that we have succeeded it at .
At present, reactor water level is becoming lower and we are injecting
water accordingly.
* Reactor of Unit 2 has been shut down and we continue injecting water by
Reactor Core Isolation Cooling System. Current reactor water level is
lower than normal level, but the water level is steady. Following the
national government instruction, we are preparing to implement a measure
to reduce the pressure of the reactor containment vessels in order to
fully secure safety.
* Reactor of Unit 3 has been shut down and we continue injecting water by
Reactor Core Isolation Cooling System. Following the national government
instruction, we are preparing to implement a measure to reduce the
pressure of the reactor containment vessels in order to fully secure
safety.
* We are implementing a measure to reduce the pressure of the reactor
containment vessels, but, one of our employees working in the Unit 1 was
irradiated at over 100mSv level(106.3mSv). He received a medical treatment
by a special physician.

Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to earthquake
* The national government has instructed evacuation for those local
residents within 3km radius of the periphery and indoor standby for those
local residents between 3km and 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
.

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]
4 stations in Fukushima Prefecture were shutdown due to earthquake.
Power stations in Yamanashi Prefecture have been restored.

[Transmission System, etc.]
5 substations shown below have been shutdown:
- Naka Substation
- Shin Motegi Substation
- Joban Substation
- Ibaraki Substation
- Nishi Mito Substation

[Blackout in TEPCO's Service Area]
Total of about 0.6 million households are out of power.
Tokyo: 0
Kanagawa Pref.: 0
Tochigi Pref.: 30,389
Chiba Pref.: 36,456
Saitama Pref: 0
Gunma Pref.: 0
Ibaraki Pref: 537,288
Yamanashi Pref: 0
Shizuoka Pref: 0 (east of Fuji River)

[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.
