The Earthquake Check In thread

Back on topic please.

 

FUCK NHK went off the air what is going on?

 

We are still not heard from our sendai people.. it's sure they have important survival to do..

I have some hundreds of dollars here for emergency help

 

Well the reactors:

They are hot water reactors, the water is used to make power and keep the cores cool.

The tsunami destroyed the generators, the backup turbines, and they ran on battery
cooling unit that ran out.

Unit 1, the steam shed (turbine) burst and now they have no cooling, and the water jacket around the reactor fell.

The cooling inside the reactor was fine, but pressure built.

Now they have water covering the core in unit 1, but units 2,3 have
no cooling.

In short three of four reactors might overheat, and they might have to release the
steam into the air which will have some radiation.

The will keep pumping water in to cool the cores (no meltdown) but radiation steam
from the cooling will be released into the air.

The rods inside have damage, so in the end all the reactors will need to be torn down, and new power plant built at costs of some billions.

As a result the reactors which provide some 35% of power won;t work, so russia is rushing emergency LPG to Japan to make the gas power plants supplied.

Bad bad times.

 

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