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. While the density of
radioactive materials in the air at the working place was below the
detectable level both for particulate materials and iodine, whole body
counter will be implemented later.
· At 1:10 pm on June 15, test operation of decontamination
instruments in the water treatment facilities was initiated using the
low level contaminated water.
· On June 15, test of decontamination was conducted inside the
truck bay door to investigate the measures of decontamination.
· At 10:33 on June 15, transfer of accumulated water in the
Unit 1 condenser to condenser storage tank was initiated.
· At 10:06 am on June 15, the amount of injected water to
the reactor was changed from approx. 5 m3/h to approx. 4.5 m3/h.
· At 10:05 on June 14, transfer of accumulated water in the
Unit 6 turbine building underground to the temporary tank was
initiated.
· On June 15, we have been spraying dust inhibitor to areas
including the area surrounding Unit 5 and 6 extra high voltage
switching station.
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.
