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, 2011, we have compiled the roadmap towards
restoration from the
accident and on July 19 we accomplished the Step1
target "Radiation dose
is in steady decline". Then on December 16 we
confirmed the accomplishment
of the Step 2 target "Release of radioactive
materials is under control
and radiation doses are being significantly held
down".
In addition, on December 21, 2011, we have compiled the
"Mid-to-long-Term
Roadmap toward the Decommissioning of Fukushima Daiichi
Nuclear Power
Units 1-4, TEPCO".
In addition to the maintenance of the plant's
stable condition, we will
implement Mid-to-Long Term countermeasures towards the
decommissioning of
Fukushima Daiichi Nuclear Power Units 1-4 to enable
evacuees to return to
their homes as soon as possible and reduce the anxiety
of the people in
Fukushima and the whole nation as soon as
possible.
Below is the status of TEPCO's major
facilities.
*Updates since the previous press release
underlined.
[Nuclear Power Station]
·Fukushima Daiichi Nuclear Power Station: Unit 1 to 3:
shut down due to
the earthquake
(Units 4 to 6: outage due to regular
inspections)
*At 9:13 am on January 16, we suspended the second
cesium absorption
apparatus due to reverse cleaning of the filters
because the amount of
disposal water of the second cesium absorption
apparatus decreased
gradually. We restarted the apparatus at 12:12 pm on
the same day. At
12:17 pm on the same day, the flow rate reached steady
state (approx.
28m3/h).
·Fukushima Daini Nuclear Power Station:
(Units 1 to 4: shutdown due to the earthquake)
*At 2:28 pm on January 16, we stopped the Residual Heat
Removal System
(System A) of Unit 1 due to the switching work from
System A to System B.
At 2:47 on the same day, we started System B.
·Kashiwazaki Kariwa Nuclear Power Station: Units 5, 6:
under normal
operation
(Units 1 to 4 and 7: outage due to regular
inspections)
[Thermal Power Station]
·Power supply has returned to normal and facilities
damaged by the
earthquake are now being handled in a timely
manner.
[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.
[Impacts on Power Supply and Demand Balance]
This winter, there will be some minus factors such as
the regular
inspection of Unit 5 at Kashiwazaki-Kariwa Nuclear
Power Station. On the
other hand, there will be several plus factors such as
the recovery of the
common thermal power stations which suffered the
earthquake. As a result,
we expect to secure 54.6 GW (at the end of January),
53.7 GW (at the end
of February) supply power.
Compared to the maximum demand in the last winter,
which is 51.5 GW, we
will have 2.2 - 3.1 GW generation reserve
margin.
We expect to maintain stable power supply this winter,
however, as there
remains possibilities of unplanned shutdowns at our
power stations and
growth in the demand according to the rapid change in
the temperature, we
would like to ask your reasonable effort to save
electricity.
We will continue to make our efforts to maintain stable
operation and
maintenance of the power facilities in order to
"prevent in principle" the
planned blackouts and secure power supply.
