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 June 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 8:51 pm on June 19 we began to open the air lock, while coordinating
a degree of its opening. Then we confirmed a result of monitoring dose
rate in the air and evaluated there was no impact in the surrounding
area. At 5:00 am on June 20 we fully opened the air lock. At 2:30 pm on
June 20, we opened the large equipment carry-in entrance of R/B.
·At 9:49 am on June 20, in order to lower dose during work at 5FL, R/B,
Unit 4, we started freshwater injection to Reactor well and equipment
storage pool.
·At 10:25 am on June 20, conducted a water flow test using highly
concentrated contaminated water in Cesium adsorption Instruments of the
water treatment facility and finished it at 2:50 pm on the same day.
·At 1:37 pm on June 20, we started transferring accumulated water in the
basement of the turbine building of Unit 2 to Condenser, turbine building,
Unit 1.
·At 10:00 am on June 20, we started transferring accumulated water in the
basement of the turbine building of Unit 6 to the temporary storage tanks.
·At 10:00 am on June 20, we started operation of the circulating seawater
purification facility installed at the screen area, Units 2 and 3.
·On June 20, we are spraying dust inhibitors to yards around Unit 5 in
order to inhibit scattering of radioactive substances on the ground by a
crawler dump truck.
On June 20, workers are spraying dust inhibitors to materials yards etc.
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 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.
