Plant Status of Fukushima Daiichi Nuclear Power Station (as of 2am March 13th)

All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.

Casualty
- 2 workers of cooperative firm were injured at the occurrence of the
earthquake, and were transported to the hospital.
- 1 TEPCO employee who was not able to stand by his own with his hand
holding left chest was transported to the hospital by an ambulance.
- 1 subcontract worker at important earthquake-proof building was
unconscious and transported to the hospital by an ambulance.
- The radiation exposure of 1 TEPCO employee, who was working inside the
reactor building, exceeded 100mSv and was transported to the hospital.
- 4 workers were injured and transported to the hospital after explosive
sound and white smoke were confirmed around the Unit 1.
- Presence of 2 TEPCO employees at the site are not confirmed

Others
- We measured radioactive materials inside of the nuclear power station
area (outdoor) by monitoring car and confirmed that radioactive
materials level is higher than ordinary level. Also, the level at
monitoring post is higher than ordinary level. We will continue to
monitor in detail the possibility of radioactive material being
discharged from exhaust stack or discharge canal. The national
government has instructed evacuation for those local residents within
20km radius of the periphery because it's possible that radioactive
materials are discharged.

- We will continue to take all measures to restore the security of
the site and to monitor the environment of the site periphery.

Japan's Edano: Work under way to control reactor

http://www.reuters.com/article/2011/03/13/us-japan-quake-nuclear-idUSTRE72C05420110313

TOKYO, March 13 (Reuters) - Attempts to control a nuclear reactor that exploded after the earthquake and subsequent tsunami in northern Japan are continuing using water supply and steam release to cool it down, the top government spokesman said on Sunday.

Friday's devastation left the No.1 reactor at Tokyo Electric Power Co's Fukushima Daiichi power plant with a crippled cooling system, causing a rise in reactor temperature and pressure.

"We are doing the two things at the same time - venting air out of the reactor and supplying water into the reactor," Chief Cabinet Secretary Yukio Edano said.

to shut the reactor down, the rods are inserted.

but it was said it could take a week to see if it works. The next four might need other resources. As it's been said Japan doesn't have enough river resources...so the plants are located near ocean.

the quake for inspection, 1, 2,3 shut down when the quake hit. The shut down system worked fine. It is the cooling they are having problems with.

Maybe someone should inform TEPCO that part of the reactor building is missing.



Press releases like this are why people do not trust the nuclear industry.

But, in THIS CASE it's a NECESSARY inspection. In our case it's just "Authoritarian." :-(

That wasn't an explosion! It was just an explosive sound and white smoke! Silly people jumping to all sorts of conclusions!

And yeah, part of your building is missing, too.

Press Release (Mar 13,2011)
Plant Status of Fukushima Daini Nuclear Power Station (as of 2:00am March 13th)

http://www.tepco.co.jp/en/press/corp-com/release/11031302-e.html

There is no update from the release issued at 1:00 am

Unit 1 (shut down at 2:48pm on March 11th)
- Reactor is shut down and reactor water level is stable.
- Offsite power is available.
- At 8:19am, there was an alarm indicating that one of the control rods was
not properly inserted, however, at 10:43am the alarm was spontaneously
called off. Other control rods has been confirmed that they are fully
inserted (reactor is in subcritical status)
- Status of main steam isolation valve: closed
- Injection of water into the reactor is done by Make-up Water Condensate
System.
- At 6:08pm, we announced the increase in reactor containment vessel
pressure, assumed to be due to leakage of reactor coolant. However, we
do not believe there is leakage of reactor coolant in the containment
vessel at this moment.
- At 5:22am, the temperature of the suppression chamber exceeded 100
degrees. As the reactor pressure suppression function was lost, at 5:22am,
it was determined that a specific incident stipulated in article 15,
clause 1 has occurred.
- We decided to prepare implementing measures to reduce the pressure of the
reactor containment vessel (partial discharge of air containing
radioactive materials) in order to fully secure safety. This preparation
work started at around 9:43am and finished at 6:00pm.
- Restoration work in reactor cooling function is in progress to achieve
reactor cold shutdown.

Impact to TEPCO's Facilities due to Miyagiken-Oki Earthquake (as of 8AM)

http://www.tepco.co.jp/en/press/corp-com/release/11031304-e.html

Below is major impact to TEPCO's facilities due to the Miyagiken-Oki
Earthquake that occurred yesterday at 2:46PM.
*new items are underlined


Fukushima Daiichi Nuclear Power Station:
Units 1 to 3: shutdown due to earthquake
Units 4 to 6: outage due to regular inspection
* The national government has instructed evacuation for those local
residents within 20km radius of the site periphery.
* The value of radioactive material (iodine, etc) is increasing according
to the monitoring car at the site (outside of the site). One of the
monitoring posts is also indicating higher than normal level.
* Since the amount of radiation at the boundary of the site exceeds the
limits, we decide at 4:17PM, Mar 12 and we have reported and/or noticed
the government agencies concerned to apply the clause 1 of the Article 15
of the Radiation Disaster Measure at 5PM, Mar 12.
* In addition, a vertical earthquake hit the site and big explosion has
happened near the Unit 1 and smoke breaks out around 3:36PM, Mar 12th.
*TextHigh Pressure Coolant Injection System of Unit 3 automatically stopped.
We endeavored to restart the Reactor Core Isolation Cooling System but
failed. Also, we could not confirm the water inflow of Emergency Core
Cooling System. As such, we decided at 5.10AM, Mar 12, and we reported
and/or noticed the government agencies concerned to apply the clause 1 of
the Article 15 of the Radiation Disaster Measure at 5:58AM, Mar 13.
In order to fully secure safety, we operated the vent valve to reduce the
pressure of the reactor containment vessels (partial release of air
containing radioactive materials) and completed the procedure at 8:41AM,
Mar 13
* We continue endeavoring to secure the safety that all we can do and
monitoring the periphery.

when they say the water level is stable, does that mean can still pump enough sea water in it faster than the melt down can turn it into radioactive steam..
