Crisis Nuclear - Terremoto y Tsunami en Japón

Han actualizado el status de los reactores y dicen que de momento siguen igual y estables:

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.

Unit 2 (shut down at 2:48pm on March 11th)

• Reactor is shut down and reactor water level is stable.
• Offsite power is available.
• Control rods 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.
• We do not believe there is leakage of reactor coolant in the containment
  vessel.
• At 5:32am, the temperature of the suppression chamber exceeded 100
  degrees. As the reactor pressure suppression function was lost, at 5:32am,
  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 10:33am and finished at 10:58pm.
• Restoration work in reactor cooling function is in progress to achieve
  reactor cold shutdown.

Unit 3 (shut down at 2:48pm on March 11th)

• Reactor is shut down and reactor water level is stable.
• Offsite power is available.
• Control rods are fully inserted (reactor is in subcritical status)
• Status of main steam isolation valve: closed
• We do not believe there is leakage of reactor coolant in the containment
  vessel.
• 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. The preparation
  woke started at around 12:08pm and finished at 12:13pm.
• Reactor cold shutdown at 12:15pm

Unit 4 (shut down at 2:48pm on March 11th)

• Reactor is shut down and reactor water level is stable.
• Offsite power is available.
• Control rods 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.
• We do not believe there is leakage of reactor coolant in the containment
  vessel.
• In order to cool down the reactor, injection of water into the reactor
  had been done by the Reactor Core Isolation Cooling System, however, At
  6:07am, the temperature of the suppression chamber exceeded 100 degrees.
  As the reactor pressure suppression function was lost, at 6:07am, 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. The preparation
  woke started at around 11:44am and finished at around 11:52am.
• Restoration work in reactor cooling function is in progress to achieve
  reactor cold shutdown.

Indication from monitoring posts installed at the site boundary did not
show any difference from ordinary level.
No radiation impact to the external environment has been confirmed. We will
continue to monitor in detail the possibility of radioactive material being
discharged from exhaust stack or discharge canal.[/i]
