TEPCO website has current updates

Tokyo Electric Power Company (TEPCO) provides periodic updates on all its power generation units on its website at: http://www.tepco.co.jp/en/index-e.html.

Of course, everything TEPCO tells us should be taken with a grain of salt.
One thing I noticed in today’s report is that some of TEPCO’s non-nuclear facilities suffered damaged and two are still out-of-service. Here’s today report:


Status of TEPCO’s Facilities and its services after the Tohoku-Chihou-Taiheiyou-Oki Earthquake(as of 3:00PM, April 25)

Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March

11th 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 17th, we have put together the roadmap towards restoration from the

accident. 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.

*New items have been 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 10:12 am on April 25th, we started water injection to spent fuel pool

 in Unit 2 by the temporary motor driven pump. The operation was completed

 at 11:18 am.

*Work to connect high voltage power panel of Unit 1/2 and Unit 5/6 is

 continuously under way. Before this work, the power source of pumps to

 inject water to reactors was switched to a temporary diesel generator a

 at 10:57 am on April 25th. The pump to inject nitrogen in Unit 1 was

 stopped from 2:10 pm on April 25th. The pump of the residual heat removal

 system to cool the reactor and spent fuel pool in Unit 5 was stopped from

 12:22 pm on April 25th.

*From 10:30 am on April 25th, the dust inhibiter was sprayed to the total

 area of 3,800 m2 around the mountain side of reactor building of Unit 5,

 slope in front of administration building, and gymnasium building. The

 operation was completed at 12:30 pm.


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 Units 2 and 4: Shutdown due to the


-Hitachinaka Thermal Power Station Unit 1: 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.


[Avoidance of further Implementation on Planned Rolling Blackouts and

Request for Conserving Electricity Consumption]

Currently, we are working to restore electricity supply after our nuclear

and thermal power facilities were severely damaged by

Tohoku-Chihou-Taiheiyou-Oki Earthquake. The widespread understanding and

cooperation of our customers to conserve electricity have contributed to

the improvement of this tight power supply-demand balance situation.

Amidst this backdrop, since the electricity supply will be able to balance

with the demand for the time being, we have decided not to implement

further rolling blackouts in principle.

However, we sincerely ask for your continued cooperation in reducing

electricity consumption due to the possible increase in demand caused by

warmer weather or unexpected trouble at power stations that are currently

being restored to service. In case the electricity supply-demand balance

becomes tighter than expected, we may regrettably need to restart the

implementation of rolling blackouts, with prior notice. We kindly ask for

your cooperation.

We will do our best to maintain this policy of avoiding further

implementation of rolling blackouts during the summer.
