Due to the Tohoku-Taiheiyou-Oki Earthquake which occurred on March 11th
2011, TEPCO's facilities including our nuclear power stations have been
severely damaged. We deeply apologize for the anxiety and inconvenience
caused.
Below is the status of TEPCO's major facilities.
*New items are underlined
[Nuclear Power Station]
Fukushima Daiichi Nuclear Power Station:
Units 1 to 3: shutdown due to the earthquake
(Units 4 to 6: outage due to regular inspections)
*At approximately 6:38 AM, April 12th, a fire broke out at the
distribution switchboard containing batteries located in the sampling
equipment switchbox situated close to the south water discharge channel
for Units 1-4. The self defense fire fighting team began extinguishing
this fire soon after it broke out. At approximately 6:45 AM, this
incident was reported to the Futaba fire authorities.
Efforts to contain the fire were successful and there are now no more
flames or smoke emanating from the switchbox.
This incident did not impact the external release of radioactive
substances or the cooling capability of the reactor. The data taken from
the monitoring of the environment in the area did not change.
At 9:12 on April 12th, Futaba Fire Fighting Head Office confirmed fire
extinguishment at the distribution switchboard.
*Below is the status of TEPCO's major facilities due to the 6.8 magnitude
earthquake centered in the Fukushima-Hama-dori earthquake which occurred
at approximately 2:07 pm, April 12th 2011,
-No shutdown of the off-site power of the units 1-6
-No abnormalities in water injection to the reactor of the units 1-3,
nitrogen gas injection to the reactor containment vessel of unit 1
-No abnormalities were detected in the parameter of each of the units.
-No abnormalities in the data taken from the monitoring before as well as
after the earthquake.
-We advised workers at outdoor to evacuate in the key earthquake-proof
building after the quake We confirmed that there were no injured workers,
we cancelled the evacuate advice at 3:05 on April 12th, 2011.
*April 12th we conducted sampling water at fuel pool, to assess the
situation of spent fuel in fuel pool. We will analyze nuclide from now
Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
-There was no impact from the 6.3 magnitude earthquake whose epicenter was
at Fukushima-Hama-dori which occurred at approximately 2:07 pm, April
12th 2011,
Kashiwazaki Kariwa Nuclear Power Station:
Units 1, 5, 6, 7: normal operation
(Units 2 to 4: outage due to regular inspection)
-There was no impact from the 6.3 magnitude earthquake whose epicenter was
at Fukushima-Hama-dori which occurred at approximately 2:07 pm, April
12th 2011
[Thermal Power Station]
-Hirono Thermal Power Station Units 2 and 4: Shutdown due to the
earthquake
-Hitachinaka Thermal Power Station Unit 1: Shutdown due to the earthquake
-Kashima Thermal Power Station Unit 6: Shutdown due to the earthquake
[Hydro Power Station]
-Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[Impacts on Transmission Facilities]
-Power supply has returned to normal and facilities damaged by the
earthquake are now being handled in a timely manner.
[Avoidance of further Implementation on Planned Rolling Blackouts and
Request for Conserving Electricity Consumption]
Currently, we are working to restore electricity supply after our nuclear
and thermal power facilities were severely damaged by
Tohoku-Taiheiyou-Oki Earthquake. The widespread understanding and
cooperation of our customers to conserve electricity have contributed to
the improvement of this tight power supply-demand balance situation.
Amidst this backdrop, in principle, we have decided not to implement
further rolling blackouts. However, we must sincerely ask for your
continued cooperation in reducing electricity consumption due to the
possible increase in demand caused by warmer weather or unexpected
trouble at power stations that are currently being restored to service.
In case the electricity supply-demand balance becomes tighter than
expected, as stated, we may reluctantly restart the implementation of
rolling blackouts. We kindly ask for your cooperation. We will do our
best to maintain this policy of avoiding further implementation of
rolling blackouts during the summer.
