TEPCO Press Release (Mar 12,2011)
Plant Status of Fukushima Daiichi Nuclear Power Station as of 1PM March 12th (11:00:00 p.m. Friday March 11 Eastern Time) 
 
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 it is now stopped. Because pressure level in
  reactor containment vessel is increasing, following the national
  government instruction, 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. Following the national
  government instruction, we are preparing to implement a measure to reduce
  the pressure of the reactor containment vessels in order to fully secure
  safety.  

We are implementing a measure to reduce the pressure of the reactor
containment vessels,

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.
