All 6 units of Fukushima Daiichi Nuclear Power Station have been shut down.
Unit 1(Shut down)
- Reactor has been shut down and steam in reactor has been cooled by
isolation condenser, but now it is stopped. Because pressure level in
reactor containment vessel is increasing, we are implementing a measure
to reduce the pressure of the reactor containment vessels in order to
fully secure safety.
Reactor water level is decreasing, we will continue injecting water step
by step.
Unit 2(Shut down)
- Reactor has been shut down and we continue injecting water by Reactor
Core Isolation Cooling System. Current reactor water level is lower than
normal level, but the water level is steady. We are preparing to
implement a measure to reduce the pressure of the reactor containment
vessels in order to fully secure safety.
Unit 3(Shut down)
- Reactor has been shut down and we continue injecting water by Reactor
Core Isolation Cooling System. We are preparing to implement a measure
to reduce the pressure of the reactor containment vessels in order to
fully secure safety.
- Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
Unit 4 (shut down due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
Unit 5 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
Unit 6 (outage due to regular inspection)
- Reactor has been shut down and sufficient level of reactor coolant to
ensure safety is maintained.
- Currently, we do not believe there is any reactor coolant leakage inside
the reactor containment vessel.
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 10km radius of the periphery because it’s possible that radioactive
materials are discharged.
Two workers of a cooperative firm were injured in the nuclear power station
premise. One with a broken bone was transported to the hospital by an
ambulance and the other by a company car.
Further, there are 2 TEPCO employees whose presence has not been confirmed.
In addition, one subcontract worker standing near important earth
quake-proof buidling was unconscious and transported to the hospital by an
ambulance.
We are presently checking on the site situation of each plant while keeping
the situation of aftershock and Tsunami in mind.
