Press Release (Mar 12,2011) Plant Status of Fukushima Daini Nuclear Power Station (as of 11pm March 12th) [New Items are underlined] 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. 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. 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. 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. There is no missing person within the power station. We are presently checking on the site situation of each plant while keeping the situation of aftershock and Tsunami in mind. A seriously injured worker who had been trapped in the crane operating console of the exhaust stack was transported to the ground at 5:13pm and confirmed dead at 5:17pm. We sincerely pray for the repose of his soul. A worker was lightly injured spraining his left ankle and cutting both knees when he fell while walking at the site. The worker has returned to work after medical treatment and rest. At 10:15pm, an earthquake occurred centered in offshore Fukushima prefecture. No damage to the plant has been found at this moment. |
