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)
· From 6:40 pm to 7:00 pm on June 17, a test operation of the whole water
treatment facilities started for high radiation-level contained water.
At 8:00 pm on June 17, a full operation started.
At 0:54 am on June18, we stopped operation of the facility temporarily
due to the radiation dose at surface level measured up to the basis of
exchange filter of Cesium adsorption Instruments.
· At 10:00 AM on June 17, we started a water transfer from the underground
floor of the turbine building of Unit 6 to temporary water tanks. At 4:00
pm on June 17, the transfer was completed.
· On June 17, spraying inhibitor for about 7,000 m2 was implemented by
worker in the ground.Fukushima Daini Nuclear Power Station:
Units 1 to 4: shutdown due to the earthquakeKashiwazaki 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 planned 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.
