Only 50 technicians are left, the rest left the installation. Can they manage the cooling of 6 reactor cores?

What about the damage of the containment in reactor 2?

What about the rods outside reactor core 4 which were taken out for maintenance checks?

What does it mean having to use helicopters to cool down the buildings? How can this be a substitute for seawater being pumped into the buildings?

How long can the remaining small group survive? 400 millisievert within one hour is a lot of radiation. Do we depend on robots if the situation gets worse? Will people sacrifice their lives to save thousands?
