Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March
11, 2011, TEPCO's facilities including our nuclear power stations have
been severely damaged. We deeply apologize for the anxiety and
inconvenience caused.
With regard to the accident at Fukushima Daiichi Nuclear Power Station,
on April 17, we have compiled the roadmap towards restoration from the
accident and then we updated the roadmap considering the current situation,
on May 17. By bringing the reactors and spent fuel pools to a stable
cooling condition and mitigating the release of radioactive materials, we
will make every effort to enable evacuees to return to their homes and for
all citizens to be able to secure a sound life.
Below is the status of TEPCO's major facilities.
*Updates from previous press release 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 11:05 am on June 15, it was confirmed that a worker from a partner
company in charge of crane assembling work for the preparing for the
installation of the cover for Unit 1 reactor building at the shallow
draft quay was smoking with his full mask off. Later it was confirmed
the density of radioactive materials in the air at the working place
was below the detectable level both for particulate materials and iodine.
The evaluation exposure dose is external exposure---0.13mSv and internal
exposure---0.24mSv.
· From 10:00 am to 4:00 pm on June 15, transfer of accumulated water in
the Unit 6 turbine building underground to the temporary tank was
implemented.
· From 1:10 pm to 8:35 pm on June 15, test operation of decontamination
instruments in the water treatment facilities was implemented with the
low level contaminated water.
· From 10:40 pm on June 15th to 12:20 am on June 16th, cesium adsorption
instruments and decontamination instruments of water treatment
facilities were operated with low-level contaminated water by trial.
· At 12:20 am on June 16th, continuous operation of the whole water
treatment facilities with low level contaminated water was initiated
· From 6:39 pm on June 4th to 8:40 am on June 16th, we transferred the
accumulated water in the vertical shaft in the turbine building of
Unit 2 to the centralized radiation waste treatment facility (process
main building).
· From 10:05 am on June 14th to 8:46 am on June 16th, we transferred the
accumulated water in the basement in the turbine building of Unit 3 to
the centralized radiation waste treatment facility (process main
building).
· On June 15, around super high voltage switching stations of Unit 5 and
6, we implemented spraying dust inhibitor (7,000㎡).
Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquake
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 Unit 2 and 4: 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.
[Perspective of Power Supply and Demand Balance in this Summer]
We have worked to restore electricity supply after our nuclear and thermal
power facilities were severely damaged by Tohoku-Chihou-Taiheiyou-Oki
Earthquake. This time, we revised that the supply capacity in this summer
would increase because we could plan to secure an additional capacity.
However, in order to maintain the policy of avoiding further
implementation of rolling blackouts during the summer, in addition to
the above increase of the supply capacity, we sincerely ask for your
continued cooperation in reducing electricity consumption. Now we are
creating concrete measures considering "Outline of Countermeasures for
Power Supply and Demand During Summertime" presented by the Electricity
Supply-Demand Emergency Response Headquarters of the Japanese government.
(Previously Announced)
It is expected that we will be able to maintain the policy of avoiding
further implementation of rolling blackouts this June because it is
estimated that we will be able to secure the capacity exceeding the
maximum forecasted demand as of now, thanks to your understanding as
well as cooperation on saving electricity.
However In the event that an unplanned outage such as excessive continuous
operation in old plants and a sudden increase of power demand due to
unusual hot temperature occur, there is a possibility to affect a stable
power supply. In order to maintain the policy of avoiding rolling
blackouts, we steadily implement to install additional power capacity we
have planed, and we continuously do our best efforts to secure supply
capacity. We apologize for the inconvenience this may cause and appreciate
for your cooperation to save electricity.
