One thing of interest, when the EQ happened at fukushima it put of service a tranformation station which cut out the connection to the eletrical grid. This condition lasted for approximately 50 minutes before being restored. After the scram the main steam turbine isolation valves shut which isolated steam to the main turbine and caused it to trip. At this point the electrical facility power that is generated by the turbine and used by various plant systems and instrumentation was also lost.

I am trying to find out what kind of diesels were used for the EMERGENY DIESELS (2 at the plant and as far as my research has indicated - water coole). Only plant 6 had a 3rd diesel that is air cooled. Without water cooling to the diesel it could have over heated as typically the jacket water system on a diesel is cooled by auxillary sytem water (similar to the secondary side in the steam turbine)

@dean hi water cooled deisels to handle loss of coolant mmmm monty python would like that
by elainekirk 5/10/2011 8:45:02 PM

indeed elaine.. that's one part of the whole equation not identified diesels have to have cooling or they shutdown

@dean I will have a look as I tootle round these docs- given myself headache - gonna have a coffee and then back to them
